1. Inserting New Breadcrumb

   CREATE PROCEDURE [dbo].[addnewbreadcrumb]
     @PageTitleParent AS VARCHAR(100),
   	@PageTitle AS VARCHAR(100),
   	@PageURL AS VARCHAR(100)
   AS
   BEGIN
   DECLARE @ParentLevel INTEGER;
   DECLARE @RecCount INTEGER;
   DECLARE @CheckRecCount INTEGER;
   DECLARE @MyPageTitle VARCHAR(100);
     -- routine body goes here, e.g.
   SET @ParentLevel = (SELECT Rgt FROM [dbo].[breadcrumblinks] WHERE 
   Page_Title = @PageTitleParent);
    
   SET @CheckRecCount = (SELECT COUNT(*) AS RecordCount FROM [dbo].[breadcrumblinks] WHERE 
   Page_Title = @PageTitle);
   	IF @CheckRecCount > 0
     BEGIN 
   		SET @MyPageTitle = 'The following Page_Title is already exists in database: ' +  @PageTitle;
   		SELECT @MyPageTitle;
   		GOTO GoodBye;
     END
    
    
   UPDATE [dbo].[breadcrumblinks] 
      SET Lft = CASE WHEN Lft > @ParentLevel THEN
         Lft + 2
       ELSE
         Lft + 0
       END,
      Rgt = CASE WHEN Rgt >= @ParentLevel THEN
         Rgt + 2
      ELSE
         Rgt + 0
      END
   WHERE  Rgt >= @ParentLevel;
    
   SET @RecCount = (SELECT COUNT(*) FROM [dbo].[breadcrumblinks]);
   	IF @RecCount = 0
       BEGIN
   		-- this is for handling the first record
   		INSERT INTO [dbo].[breadcrumblinks] (Page_Title, Page_URL, Lft, Rgt)
   					VALUES (@PageTitle, @PageURL, 1, 2);
   		END
   	ELSE
       BEGIN
   		-- whereas the following is for the second record, and so forth!
   		INSERT INTO [dbo].[breadcrumblinks] (Page_Title, Page_URL, Lft, Rgt)
   					VALUES (@PageTitle, @PageURL, @ParentLevel, (@ParentLevel + 1));
    
   	  END
    
     GoodBye:
    
   END
   GO

2. Removing or Deleting Breadcrumb

   CREATE PROCEDURE [dbo].[deletebreadcrumbbasedonpagetitle]
     @PageTitle AS VARCHAR(100)
   AS
   BEGIN
    
   DECLARE @DeletedPageTitle VARCHAR(100);
   DECLARE @DeletedLft INTEGER;
   DECLARE @DeletedRgt INTEGER;
    
   SELECT @DeletedPageTitle=Page_Title, @DeletedLft=Lft, @DeletedRgt=Rgt
   FROM   [dbo].[breadcrumblinks] 
   WHERE  Page_Title = @PageTitle;
    
   DELETE FROM [dbo].[breadcrumblinks]
   WHERE Lft BETWEEN @DeletedLft AND @DeletedRgt;
    
   UPDATE [dbo].[breadcrumblinks]
      SET Lft = CASE WHEN Lft > @DeletedLft THEN
                Lft - (@DeletedRgt - @DeletedLft + 1)
             ELSE
                Lft
             END,
          Rgt = CASE WHEN Rgt > @DeletedLft THEN
                Rgt - (@DeletedRgt - @DeletedLft + 1)
             ELSE
                Rgt
             END
      WHERE Lft > @DeletedLft
         OR Rgt > @DeletedLft;
   END
   GO

3. Moving Breadcrumb to Another Parent

   CREATE PROCEDURE [dbo].[movebreadcrumb]
     @CurrentRoot AS VARCHAR(100),
   	@NewParent AS VARCHAR(100)
   AS
   BEGIN
     -- routine body goes here, e.g.
     DECLARE @Origin_Lft INTEGER;
   	DECLARE @Origin_Rgt INTEGER;
   	DECLARE @NewParent_Rgt INTEGER;
    
   SELECT @Origin_Lft=Lft, @Origin_Rgt=Rgt
   	FROM [dbo].breadcrumblinks 
   	WHERE Page_Title = @CurrentRoot;
   SET @NewParent_Rgt = (SELECT Rgt FROM [dbo].breadcrumblinks
   	WHERE Page_Title = @NewParent);
   UPDATE [dbo].breadcrumblinks 
   	SET Lft = Lft + 
   	CASE
   		WHEN @NewParent_Rgt < @Origin_Lft
   			THEN CASE
   				WHEN Lft BETWEEN @Origin_Lft AND @Origin_Rgt
   					THEN @NewParent_Rgt - @Origin_Lft
   				WHEN Lft BETWEEN @NewParent_Rgt	AND @Origin_Lft - 1
   					THEN @Origin_Rgt - @Origin_Lft + 1
   				ELSE 0 END
   		WHEN @NewParent_Rgt > @Origin_Rgt
   			THEN CASE
   				WHEN Lft BETWEEN @Origin_Lft	AND @Origin_Rgt
   					THEN @NewParent_Rgt - @Origin_Rgt - 1
   				WHEN Lft BETWEEN @Origin_Rgt + 1 AND @NewParent_Rgt - 1
   					THEN @Origin_Lft - @Origin_Rgt - 1
   				ELSE 0 END
   			ELSE 0 END,
   	Rgt = Rgt + 
   	CASE
   		WHEN @NewParent_Rgt < @Origin_Lft
   			THEN CASE
   		WHEN Rgt BETWEEN @Origin_Lft AND @Origin_Rgt
   			THEN @NewParent_Rgt - @Origin_Lft
   		WHEN Rgt BETWEEN @NewParent_Rgt AND @Origin_Lft - 1
   			THEN @Origin_Rgt - @Origin_Lft + 1
   		ELSE 0 END
   		WHEN @NewParent_Rgt > @Origin_Rgt
   			THEN CASE
   				WHEN Rgt BETWEEN @Origin_Lft AND @Origin_Rgt
   					THEN @NewParent_Rgt - @Origin_Rgt - 1
   				WHEN Rgt BETWEEN @Origin_Rgt + 1	AND @NewParent_Rgt - 1
   					THEN @Origin_Lft - @Origin_Rgt - 1
   				ELSE 0 END
   			ELSE 0 END;
    
   END
   GO

Hope it helps!

1. First of all, alter your ost_groups table by adding the three new fields called by using the following script into your osTicket database (please adjust the table prefix if you are using the different one with mine using ost_):

   ALTER TABLE `ost_groups` ADD COLUMN `can_post_reply` tinyint(1) UNSIGNED NOT NULL DEFAULT 1 AFTER `can_create_tickets`;
   ALTER TABLE `ost_groups` ADD COLUMN `can_post_internal_notes` tinyint(1) UNSIGNED NOT NULL DEFAULT 1 AFTER `can_post_reply`;
   ALTER TABLE `ost_groups` ADD COLUMN `can_assign_tickets` tinyint(1) UNSIGNED NOT NULL DEFAULT 1 AFTER `can_post_internal_notes`;

2. Open your /include/staff/group.inc.php file, and find this code:

           <tr><th>Can <b>Create</b> Tickets</th>

Hopefully you find it useful.

Some of the advantages of this Nested Set Data Model are:

1. You can create unlimited levels and it only needs one query to get all the related path.
2. Since it only need one query, then it is faster to get and display the full path.
3. It is easy to manage the records (inserting, deleting, and moving record). We will focus on this item in this article using MySQL database.

The only one disadvantage of this model is it is more complex than the others. You have to be careful to manage all of the records (inserting, deleting, and moving), otherwise you will break all of the breadcrumb records!

I came across the following article: Using the Nested Set Data Model for Breadcrumb Links and I think this is the smartest way how you can create the independent breadcrumb for any websites which have not implemented it. Since that article only explained how to add and delete a row (breadcrumb), but had not explained more detail how can you move the certain breadcrumb from the current position to the new parent, then in this article I wrote, I will try to explain you step by step, how you can create the Stored Procedures in MySQL for inserting new breadcrumb, deleting breadcrumbs based on their parent, and also: Moving the Breadcrumb from the current location to the new parent. This will be helpful to manage your breadcrumb easily and quickly especially if the current location has many breadcrumb childs. If you do not handle this carefully then you will destroy all of your breadcrumb records in your table.

1. Creating Table for Breadcrumb

   First of all, let’s create a table which we will use to store all the breadcrumb records using the following SQL query:

   CREATE TABLE `breadcrumblinks` (
     `Page_Title` VARCHAR(100) NOT NULL,
     `Page_URL` VARCHAR(100) NOT NULL,
     `Lft` int(4) NOT NULL,
     `Rgt` int(4) NOT NULL,
     PRIMARY KEY (`Page_Title`)
   ) ENGINE=MyISAM DEFAULT CHARSET=utf8;

2. Inserting New Breadcrumb

   Now let’s create a Stored Procedure for adding a new record to your breadcrumblinks table above:

   CREATE PROCEDURE `addnewbreadcrumb`(IN PageTitleParent VARCHAR(100), 
                                       PageTitle VARCHAR(100), 
                                       PageURL VARCHAR(100))
   GoodBye: BEGIN
   -- Need three parameters (PageTitleParent, PageTitle, and PageURL), 
   -- look at this line --> `Page_Title` = PageTitleParent);
   -- look at this line --> VALUES (PageTitle, PageURL, ParentLevel, (ParentLevel + 1));
   DECLARE ParentLevel INTEGER;
   DECLARE RecCount INTEGER;
   DECLARE CheckRecCount INTEGER;
   DECLARE MyPageTitle VARCHAR(100);
    
   SET ParentLevel = (SELECT Rgt FROM `breadcrumblinks` WHERE 
   `Page_Title` = PageTitleParent);
    
   SET CheckRecCount = (SELECT COUNT(*) AS RecCount FROM `breadcrumblinks` WHERE 
   `Page_Title` = PageTitle);
   	IF CheckRecCount > 0 THEN
   		SET MyPageTitle = CONCAT("The following Page_Title is already exists in database: ", PageTitle);
   		SELECT MyPageTitle;
   		LEAVE GoodBye;
     END IF;
    
   UPDATE `breadcrumblinks`
      SET Lft = CASE WHEN Lft > ParentLevel THEN
         Lft + 2
       ELSE
         Lft + 0
       END,
      Rgt = CASE WHEN Rgt >= ParentLevel THEN
         Rgt + 2
      ELSE
         Rgt + 0
      END
   WHERE  Rgt >= ParentLevel;
    
   SET RecCount = (SELECT COUNT(*) FROM `breadcrumblinks`);
   	IF RecCount = 0 THEN
   		-- this is for handling the first record
   		INSERT INTO `breadcrumblinks` (Page_Title, Page_URL, Lft, Rgt)
   					VALUES (PageTitle, PageURL, 1, 2);
   	ELSE
   		-- whereas the following is for the second record, and so forth!
   		INSERT INTO `breadcrumblinks` (Page_Title, Page_URL, Lft, Rgt)
   					VALUES (PageTitle, PageURL, ParentLevel, (ParentLevel + 1));
   	END IF;
    
   END

   Now let’s discuss that Stored Procedure (SP) above:
   Look at this following line:

   CREATE PROCEDURE `addnewbreadcrumb`(IN PageTitleParent VARCHAR(100), 
                                       PageTitle VARCHAR(100), 
                                       PageURL VARCHAR(100))

   We see that this SP has a name: addnewbreadcrumb, and it needs three parameters.
   They are:
   - PageTitleParent: This parameter is the page title parent of your new breadcrumb,
   - PageTitle: This parameter is the page title of your new breadcrumb,
   - PageURL: This parameter is the page URL of your new breadcrumb.

   Here is how we can keep the ParentLevel value based on the PageTitleParent parameter using this following SQL:

   SET ParentLevel = (SELECT Rgt FROM `breadcrumblinks` WHERE 
   `Page_Title` = PageTitleParent);

   Before we add a new breadcrumb record, let’s check to the table whether the new record that we will insert has already exists or not using this following code (this is important in order to avoid the summing up the value of Lft and Rgt of the breadcrumb):

   SET CheckRecCount = (SELECT COUNT(*) AS RecCount FROM `breadcru.mblinks` WHERE 
   `Page_Title` = PageTitle);
   	IF CheckRecCount > 0 THEN
   		SET MyPageTitle = CONCAT("The following Page_Title is already exists in database: ", PageTitle);
   		SELECT MyPageTitle;
   		LEAVE GoodBye;
     END IF;

   That code will tell us, if the record already exists, then display the custom message: “The following Page_Title is already exists in database: {ThePageTitle}”, and then exit from that SP by jumping to GoodBye label before the BEGIN statement above.

   The rest of that code is for adding the new breadcrumb. Important to know, that I added the special handling for adding the first record if the table is still empty, and also for adding the second record and so forth. Please look at the following code:

   SET RecCount = (SELECT COUNT(*) FROM `breadcrumblinks`);
   	IF RecCount = 0 THEN
   		-- this is for handling the first record
   		INSERT INTO `breadcrumblinks` (Page_Title, Page_URL, Lft, Rgt)
   					VALUES (PageTitle, PageURL, 1, 2);
   	ELSE
   		-- whereas the following is for the second record, and so forth!
   		INSERT INTO `breadcrumblinks` (Page_Title, Page_URL, Lft, Rgt)
   					VALUES (PageTitle, PageURL, ParentLevel, (ParentLevel + 1));
   	END IF;

   So, if you want to add your new breadcrumb record, simply execute this addnewbreadcrumb SP.

3. Removing or Deleting Breadcrumb

   Now let’s create another SP for deleting the certain breadcrumb based on the given PageTitle parameter. This SP only needs one parameter (PageTitle):

   CREATE PROCEDURE `deletebreadcrumbbasedonpagetitle` (IN `PageTitle` VARCHAR(100))
   BEGIN
   -- Need one parameter (PageTitle), look at the line: WHERE  Page_Title = PageTitle;
   DECLARE DeletedPageTitle VARCHAR(100);
   DECLARE DeletedLft INTEGER;
   DECLARE DeletedRgt INTEGER;
    
   SELECT `Page_Title`, `Lft`, `Rgt`
   INTO   DeletedPageTitle, DeletedLft, DeletedRgt
   FROM   `breadcrumblinks`
   WHERE `Page_Title` = PageTitle;
    
   DELETE FROM `breadcrumblinks`
   WHERE Lft BETWEEN DeletedLft AND DeletedRgt;
    
   UPDATE `breadcrumblinks`
      SET Lft = CASE WHEN Lft > DeletedLft THEN
                Lft - (DeletedRgt - DeletedLft + 1)
             ELSE
                Lft
             END,
          Rgt = CASE WHEN Rgt > DeletedLft THEN
                Rgt - (DeletedRgt - DeletedLft + 1)
             ELSE
                Rgt
             END
      WHERE Lft > DeletedLft
         OR Rgt > DeletedLft;
   END

   If you want to remove or delete the certain breadcrumb record, simply execute this deletebreadcrumbbasedonpagetitle SP.

4. Moving Breadcrumb to Another Parent

   So far we have already had the 2 SPs for inserting and deleting breadcrumb records. How about moving breadcrumb? Good question! Now the most important thing that we have to handle is how we can move the certain breadcrumb from the current position to the new parent. This is very important, especially if you want to move the certain breadcrumb which have so many childs beneath it. So we will create the third SP as following:

   CREATE PROCEDURE `movebreadcrumb`(IN CurrentRoot VARCHAR(100), IN NewParent VARCHAR(100))
   BEGIN
   -- Need two parameters: (1) CurrentRoot, and (2) NewParent.
   DECLARE Origin_Lft INTEGER;
   DECLARE Origin_Rgt INTEGER;
   DECLARE NewParent_Rgt INTEGER;
    
   SELECT `Lft`, `Rgt`
   	INTO Origin_Lft, Origin_Rgt
   	FROM `breadcrumblinks`
   	WHERE `Page_Title` = CurrentRoot;
   SET NewParent_Rgt = (SELECT `Rgt` FROM `breadcrumblinks`
   	WHERE `Page_Title` = NewParent);
   UPDATE `breadcrumblinks` 
   	SET `Lft` = `Lft` + 
   	CASE
   		WHEN NewParent_Rgt < Origin_Lft
   			THEN CASE
   				WHEN Lft BETWEEN Origin_Lft AND Origin_Rgt
   					THEN NewParent_Rgt - Origin_Lft
   				WHEN Lft BETWEEN NewParent_Rgt	AND Origin_Lft - 1
   					THEN Origin_Rgt - Origin_Lft + 1
   				ELSE 0 END
   		WHEN NewParent_Rgt > Origin_Rgt
   			THEN CASE
   				WHEN Lft BETWEEN Origin_Lft	AND Origin_Rgt
   					THEN NewParent_Rgt - Origin_Rgt - 1
   				WHEN Lft BETWEEN Origin_Rgt + 1 AND NewParent_Rgt - 1
   					THEN Origin_Lft - Origin_Rgt - 1
   				ELSE 0 END
   			ELSE 0 END,
   	Rgt = Rgt + 
   	CASE
   		WHEN NewParent_Rgt < Origin_Lft
   			THEN CASE
   		WHEN Rgt BETWEEN Origin_Lft AND Origin_Rgt
   			THEN NewParent_Rgt - Origin_Lft
   		WHEN Rgt BETWEEN NewParent_Rgt AND Origin_Lft - 1
   			THEN Origin_Rgt - Origin_Lft + 1
   		ELSE 0 END
   		WHEN NewParent_Rgt > Origin_Rgt
   			THEN CASE
   				WHEN Rgt BETWEEN Origin_Lft AND Origin_Rgt
   					THEN NewParent_Rgt - Origin_Rgt - 1
   				WHEN Rgt BETWEEN Origin_Rgt + 1	AND NewParent_Rgt - 1
   					THEN Origin_Lft - Origin_Rgt - 1
   				ELSE 0 END
   			ELSE 0 END;
   END

   You will see that this SP needs two parameter as you can see from this following line:

   CREATE PROCEDURE `movebreadcrumb`(IN CurrentRoot VARCHAR(100), IN NewParent VARCHAR(100))

   They are:
   - CurrentRoot: This is the name of the current page title that you want to move.
   - NewParent: This is the name of the page title where the CurrentRoot will be moved to. In other words, this is the new parent page title where the CurrentRoot will be located after the moving process is successfully done.

   If you want to move the certain breadcrumb record, simply execute this movebreadcrumb SP.

5. Retrieving Breadcrumb

   As I mentioned above, you only need one query to get the full path of the certain given page.
   Here is one of the example of the code how you can retrieve the certain breadcrumb of the (e.g) ‘Statistik per Jam’ page:

   SELECT C.* FROM `breadcrumblinks` AS B, `breadcrumblinks` AS C
   WHERE (B.Lft BETWEEN C.Lft AND C.Rgt)
   AND (B.Page_Title = 'Statistik per Jam')
   ORDER BY C.Lft;

1. First of all, alter your ost_config table by adding a new field called allow_mandatory_attachments by using the following script into your osTicket database (please adjust the table prefix if you are using the different one with mine using ost_):

   ALTER TABLE `ost_config` ADD COLUMN `allow_mandatory_attachments` TINYINT(1)  NOT NULL DEFAULT '0' AFTER `allow_attachments`;

2. Open your /include/client/open.inc.php file, and find this code (you will never find this code if you have not implemented the Multiple Attachments for Client Side of osTicket 1.6 RC5 mod above):

           <td>
               <!-- <input type="file" name="attachment"><font class="error">&nbsp;<?=$errors['attachment']?></font> -->
               <input id="my_file_element" type="file" name="file_1" ><font class="error">&nbsp;<?=$errors['file_1']?></font>
           </td>

   then replace it with this following code:

           <td>
               <!-- <input type="file" name="attachment"><font class="error">&nbsp;<?=$errors['attachment']?></font> -->
               <input id="my_file_element" type="file" name="file_1" value="document.getElementById( 'my_file_element' )"><font class="error">
   			<?php // MOD Mandatory Attachments, by Masino Sinaga, October 8, 2011  
   			if ($cfg->allowMandatoryAttachments()) { 
   			  echo '&nbsp;*'; 
   			} else { 
   			  echo ''; 
   			} 
   			// MOD Mandatory Attachments, by Masino Sinaga, October 8, 2011 ?>&nbsp;<?=$errors['file_1']
   			?>
   			</font>
           </td>

3. Open your /include/class.ticket.php file, and find this code:

           $fields['message']  = array('type'=>'text',     'required'=>1, 'error'=>'Message required');

   after that line, please insert this following code:

           // MOD Mandatory Attachments, by Masino Sinaga, October 8, 2011
           if ($cfg->allowAttachments() && $cfg->allowMandatoryAttachments()) {
             $totalsize=0;
             foreach($_FILES as $file) {
               if ($file['name']!='') {
                  $totalsize = $totalsize + $file['size'];
               }
             }
             if ($totalsize==0) {
                $fields['file_1']  = array('type'=>'string',     'required'=>1, 'error'=>'Attachment file(s) required');
             }
           }
           // MOD Mandatory Attachments, by Masino Sinaga, October 8, 2011

   So here is the idea for this mod. First of all, we checked whether the system is allowing the attachments and the mandatory attachments. Secondly, it will check the file size of the attachments in order to make sure the current ticket has the attachments file attached to it. If the conditions in first step are met but the file size is equal with zero, then system reject or cancel the submission and inform the client of a missing attachment.

4. Open your /include/class.config.php file, and find this code:

       function allowAttachments() {
           return $this->config['allow_attachments']?true:false;
       }

   after the last line of that code, please insert this following code:

       // MOD Mandatory Attachments, by Masino Sinaga, October 8, 2011
       function allowMandatoryAttachments() {
           return $this->config['allow_mandatory_attachments']?true:false;
       }
       // MOD Mandatory Attachments, by Masino Sinaga, October 8, 2011

5. Open your /include/staff/attachment.inc.php file, and find this code:

             <tr>
               <th width="165">Allow Attachments:</th>
               <td>
                 <input type="checkbox" name="allow_attachments" <?=$config['allow_attachments'] ?'checked':''?>><b>Allow Attachments</b>
                   &nbsp; (<i>Global Setting</i>)
                   &nbsp;<font class="error">&nbsp;<?=$errors['allow_attachments']?></font>
               </td>
             </tr>

   after the last line of that code, please insert this following code:

             <?php // MOD Mandatory Attachments, by Masino Sinaga, October 8, 2011 ?>
             <tr>
               <th width="165">Mandatory Attachments:</th>
               <td>
                 <input type="checkbox" name="allow_mandatory attachments" <?=$config['allow_mandatory_attachments'] ?'checked':''?>><b>Allow Mandatory Attachments</b>  &nbsp;<font class="error">&nbsp;<?=$errors['allow_mandatory_attachments']?></font>
               </td>
             </tr>
             <?php // MOD Mandatory Attachments, by Masino Sinaga, October 8, 2011 ?>

6. Open your /scp/admin.php file, and find this code:

                  $sql= 'UPDATE '.CONFIG_TABLE.' SET allow_attachments='.db_input(isset($_POST['allow_attachments'])?1:0).
                       ',upload_dir='.db_input($_POST['upload_dir']).

   then replace it with this following code:

                  $sql= 'UPDATE '.CONFIG_TABLE.' SET allow_attachments='.db_input(isset($_POST['allow_attachments'])?1:0).
                        ',allow_mandatory_attachments='.db_input(isset($_POST['allow_mandatory_attachments'])?1:0). // MOD Mandatory Attachments, by Masino Sinaga, October 8, 2011
                       ',upload_dir='.db_input($_POST['upload_dir']).

Once again, I remind you, please do not forget to set Mandatory Attachments after implementing the modification code above. Go to your Admin Panel -> Settings -> Attachments, and give a tick mark at the “Mandatory Attachments” -> “Allow Mandatory Attachments”, and save the settings, afterwards you will be able to allow the mandatory attachments for your client on submitting a ticket via your osTicket system.

1. Go to your wp-admin (Dashboard), click on Tools -> WP-Table Reloaded, edit your existing table, then insert this following code into your Custom Commands text field in the DataTables JavaScript Features:

   "aoColumns": [ { "sSortDataType": "dom-text" }, { "sSortDataType": "dom-text" }, { "sSortDataType": "dom-text" }, { "sSortDataType": "dom-text" }, { "sSortDataType": "numeric", "sType": "numeric" }]

   From that code above, in order to define the columns, we use aoColumns as the keyword. We can see that from the first until the fourth column has sSortDataType property and the value is dom-text. In the fifth column, both sSortDataType and sType have the value of numeric.

2. Save the changes and reload your table in the front-end of your website.

The important thing that you need to know is when you define a column as the Numeric data type, then you cannot insert another the different data type. In addition, you cannot format the data, for example, by adding the comma or dot character as separator directly to the data.

Here is the steps you have to do:

1. Go to your wp-admin (Dashboard) of your website, and click on the Tools -> WP-Table Reloaded, and then click on the Plugin Options.
2. Make sure you have already checked the “Yes, include and load the following custom CSS commands. This should be used to change the table layout and styling.” item, next to the “Custom CSS:” directive.
3. In the Custom CSS: directive, enter this following code:

   .wp-table-reloaded-id-1 .row-1 .column-1, .row-1 .column-2, .row-1 .column-3, .row-1 .column-4, .row-1 .column-5 { 
         text-align: center; 
   }
   .wp-table-reloaded-id-1 .column-1, .column-4 { 
         text-align: right; 
   }
   .wp-table-reloaded-id-1 .column-3 { 
         text-align: center; 
   }

   From that code above, assuming there is only one table (with table id = 1) that I have created, so you will see that .wp-table-reloaded-id-1 means that this style will be applied to the table which has the table id = 1. If you want to apply it also to another table (for example the table which table id = 2), then simply using .wp-table-reloaded-id-2, and so on.

   Another important thing that you need to know is that if you want to change the table style only for the certain row and column, then you have to write down the .row part must precede the .column, as being shown in the following example:

   .wp-table-reloaded-id-1 .row-1 .column-1, .row-1 .column-2, .row-1 .column-3, .row-1 .column-4, .row-1 .column-5 { 
         text-align: center; 
   }

   But if you want to change the style for the whole column (regardless which row it is), then you don’t need to include the .row, as being shown in the following code:

   .wp-table-reloaded-id-1 .column-1, .column-4 { 
         text-align: right; 
   }
   .wp-table-reloaded-id-1 .column-3 { 
         text-align: center; 
   }

4. Save the changes, and make sure your table has a new style.

1. Open your /wp-content/plugins/wp-table-reloaded/js/jquery.datatables.min.js file, and find this code:

   aLengthMenu=[10,25,50,100]

   then replace it with this following code:

   aLengthMenu=[5,10,25,50,100,200,500]

   In this case, we will add the other options besides the existing values “10,25,50,100″ (4 options value) to become “5,10,25,50,100,200,500″ (7 options value).

2. Still in that .js file, find again this code:

   this._iDisplayLength=10;this._iDisplayStart=0;this._iDisplayEnd=10;

   then replace it with this following code:

   this._iDisplayLength=50;this._iDisplayStart=0;this._iDisplayEnd=50;

   It means that we will change the default selected record count in the table from 10 to 50. For example, your table has 175 records or rows in it, then each time your table will be displayed, there are at least maximum 50 instead of 10 records in that table for the very first time.

Keep in mind that since this modification involves the javascript file that belongs to this plugin, then you have to re-apply the modification each time after you update this plugin to the latest version. Hope it helps.

Edited (a few minutes after I submit this post): After involving discussion with Tobias in this thread, I found the best approach in order to not edit the core file of this plugin.

Here is the trick how you can change the default selected record count or rows value and how you can change (add/edit/remove) the options value in the Show entries selector:

1. Go to your wp-admin (Dashboard), click on “Tools” -> “WP-Table Reloaded”, edit your existing table, then insert this following code (according to the original example in the modification above) into your “Custom Commands” text field in the “DataTables JavaScript Features”:

   "aLengthMenu": [[5, 10, 25, 50, 100, 200, 500, -1], [5, 10, 25, 50, 100, 200, 500, "All"]], "iDisplayLength": 100

   There are two parts from the command code that we need to know.
   - aLengthMenu, holds the options value in “Show entries” selector that you can set it up by yourself. “-1″ in the left side is equal with the “All” string that will be displayed in the front-end.
   - iDisplayLength, holds the default selected record count or rows when your table is reloaded for the very first time. I set it up with 100 instead of 50, in order to make sure that this command code will overide the change I made in the javascript file above.

   The main benefit of this command code that I will not worry losing my modification after update it to the latest version.

2. Save the changes and see the results.

Again, thanks to Tobias for pointing it out to us.

Only a small change, actually. Open your /wp-content/plugins/genesis-slider/plugin.php file, and find this code:

$read_more = genesis_get_slider_option( 'slideshow_more_text' );

then replace it with this code:

$read_more = __(genesis_get_slider_option( 'slideshow_more_text' ), 'genesis-slider'); // modified by Masino Sinaga, September 15, 2011

Hope it helps.

1. Open your /include/staff/viewticket.inc.php file, and find this code:

           <div class="tabber">

   after that line, insert this following code:

       <?php // Begin of MOD List Attachment Files in View Ticket, by Masino Sinaga, September 12, 2011 ?>
   	<?php if ($ticket->checkAttachments()) { ?>
       <div id="attachments" class="tabbertab">
         <h2>Attachments</h2>		
           <table align="center" class="message" cellspacing="0" cellpadding="1" width="100%" border=0>
            <tr class="header"><td><?=$ticket->getAttachments($id)?></td></tr> 
   		</table>
       </div>
   	<?php } ?>
   	<?php // End of MOD List Attachment Files in View Ticket, by Masino Sinaga, September 12, 2011 ?>

2. Open your /include/class.ticket.php file, and find this code:

       function getAttachmentStr($refid,$type){

   before that line, insert this following code:

       // Begin of MOD List Attachment Files in View Ticket, by Masino Sinaga, September 8, 2011
       function getAttachments($refid){        
           $sql ='SELECT attach_id,ref_id,file_size,file_name FROM '.TICKET_ATTACHMENT_TABLE.
                ' WHERE deleted=0 AND ticket_id='.db_input($this->getId()). ' ORDER BY attach_id DESC';
           $res=db_query($sql);
           if($res && db_num_rows($res)){
               while(list($id,$refid,$size,$name)=db_fetch_row($res)){
                   $hash=MD5($this->getId()*$refid.session_id());
                   $size=Format::file_size($size);
                   $name=Format::htmlchars($name);
                   $attachstr .= "<a class='Icon file' href='attachment.php?id=$id&ref=$hash' target='_blank'><b>$name</b></a>&nbsp;(<i>$size</i>)&nbsp;&nbsp;<br />";
               }
           }
           return ($attachstr);
       }
    
       function checkAttachments() {
           $sql ='SELECT file_name FROM '.TICKET_ATTACHMENT_TABLE.
                ' WHERE deleted=0 AND ticket_id='.db_input($this->getId());
           $res=db_query($sql);
           if($res && db_num_rows($res)){
              return TRUE;
           } else {
              return FALSE;
           }
       }
       // End of MOD List Attachment Files in View Ticket, by Masino Sinaga, September 8, 2011

1. Open your /include/staff/viewticket.inc.php file, and find this code:

   <div id='ticketnotes' style="display:<?=$display?>;text-align:center;">

   then replace it with this following code:

   <div id='ticketnotes' style="display:none;text-align:center;">

2. Still in the same file above, find again this code:

   <div id="ticketthread">

   then replace it with this following code:

   <div id="ticketthread" style="display:none">

Hope it helps.
