Improving Basic Filter Become Advanced Filter in Pods CMS of WordPress

Masino Sinaga — Sat, 26 Sep 2009 07:46:26 +0000

Currently, the Filter Form up to Pods CMS version 1.7.3 still uses the basic form. It has one textbox and one button only. In addition, this filter form can only filter the recordset that returned by its process based on the name field. So I made modification/enhancement by adding combobox that contains of all fields from the table in order to make user easier to choose based which field they will filter, which has default is filter in all fields or any field. Besides that, I also added the search type, whether Match Case or not, Page Limit selection, and the field selection to give user choices sorting the recordset based on the certain field and the certain sort type.

Open \pods\core\list_filters.php file, and find this code:

// Display the search box and submit button
$search = empty($_GET['search']) ? '' : $_GET['search'];
?>
         echo $search; ?>" />
         echo $label; ?>" />

then replace with this following code:

// Display the search box and submit button
$search = empty($_GET['search']) ? '' : $_GET['search'];
$match = empty($_GET['match']) ? '1' : $_GET['match']; 
$pagelimit = empty($_GET['limit']) ? '10' : $_GET['limit'];
$field = empty($_GET['field']) ? '(Any-field)' : $_GET['field'];
$sortby = empty($_GET['sortby']) ? 'id' : $_GET['sortby'];
$sorttype = empty($_GET['sorttype']) ? 'ASC' : $_GET['sorttype'];
?>
 
 
   $strField = "SHOW FIELDS FROM `wp_pod_tbl_$datatype`";
   $resultField = mysql_query($strField);
   $numberField = mysql_numrows($resultField);
   $arrField[0]='(Any-field)';
   $strSearchField = "";
   for ($i=1; $i<=$numberField; $i++) {
     $arrField[$i] = mysql_result($resultField, $i-1, "Field");
   }
   echo ("");echo("\n");
 
   echo("");
 
?>
 
   
 
 
   echo ("\n");
 
   echo("
    Field: 
   for ($i=0; $i<=$numberField; $i++)
   {
     $strSelField = ($arrField[$i]==$field) ? 'selected' : '';
     echo (" value=\"$arrField[$i]\">$arrField[$i]");
   }
   echo ("  Match: Page limit:   echo $label; ?> " />
   
    echo $label; ?>:  echo $search; ?>" /> Sort by: 
   for ($i=1; $i<=$numberField; $i++)
   {
     $strSelSortBy = ($arrField[$i]==$sortby) ? 'selected' : '';
     echo (" value=\"$arrField[$i]\">$arrField[$i]");
   }
   echo ("  Sort type: 
");	   
?>

Open \pods\core\Pod.class.php file, and find this code:

    function findRecords($orderby = 'id DESC', $rows_per_page = 15, $where = null, $sql = null)
    {
        $page = $this->page;
        $datatype = $this->datatype;
        $datatype_id = $this->datatype_id;
        $limit = ($rows_per_page * ($page - 1)) . ', ' . $rows_per_page;
        $where = empty($where) ? '' : "AND $where";
        $this->rpp = $rows_per_page;
        $i = 0;
 
        // Handle search
        if (!empty($_GET['search']))
        {
            $val = mysql_real_escape_string(trim($_GET['search']));
            $search = "AND (t.name LIKE '%$val%')";
        }
 
        // Add "t." prefix to $orderby if needed
        if (false !== strpos($orderby, ',') && false === strpos($orderby, '.'))
        {
            $orderby = 't.' . $orderby;
        }

then replace with this following code:

    function findRecords($orderby = 'id DESC', $rows_per_page = 15, $where = null, $sql = null)
    {
        $page = $this->page;
        $datatype = $this->datatype;
        $datatype_id = $this->datatype_id;
        $limit = ($rows_per_page * ($page - 1)) . ', ' . $rows_per_page;
        $match = $_GET['match'];
        $where = empty($where) ? '' : "AND $where";
        $this->rpp = $rows_per_page;
        $i = 0;
 
        // Handle search
        if (!empty($_GET['search']))
        {
           $val = mysql_real_escape_string(trim($_GET['search']));
 
           // Check which field, added by Masino Sinaga, Sept 25, 2009
           if ($_GET['field']!='') {
             if ($_GET['field']=='(Any-field)') {
 
               $strField = "SHOW FIELDS FROM `wp_pod_tbl_$datatype`";
               $resultField = mysql_query($strField);
               $numberField = mysql_numrows($resultField);
               $arrField[0]='(Any-field)';
               $strSearchField = " (";
               for ($i=1; $i<=$numberField; $i++) {
                 $arrField[$i] = mysql_result($resultField, $i-1, "Field");
                 if (($i==1) || (($i<$numberField) && ($i>=1))) {
	           $strSearchField .= ($match=='1') ? " t.$arrField[$i] like '%$val%' OR" : " t.$arrField[$i] like '$val' OR";

How to Prevent Displaying SQL Error Message in Pods CMS

Masino Sinaga — Fri, 25 Sep 2009 07:53:46 +0000

I have been running Pods CMS version 1.7.3 on this blog. So far so good, until I found a SQL error if the pg parameter in URL assigned with invalid value. For example, the proper value should be 1, 2, and so on, then you assign this parameter with non-numerical value, such as aa, etc. The message error that shown up contains of the MySQL Query including the table name. In my humble opinion, this error message should not be displayed on the client’s browser page for the security reason. So, I made modification to prevent displaying this SQL Error Message on functions.php file of this Pods CMS.

Open your \pods\core\functions.php file, and find this code:

function pod_query($sql, $error = 'SQL failed', $results_error = null, $no_results_error = null)
{
    global $table_prefix;
 
    $sql = str_replace('@wp_', $table_prefix, $sql);
 
    $result = mysql_query($sql) or die("Error: $error; SQL: $sql; Response: " . mysql_error());
    if (0 < @mysql_num_rows($result))
    {
        if (!empty($results_error))
        {
            die("Error: $results_error");
        }
    }
    else
    {
        if (!empty($no_results_error))
        {
            die("Error: $no_results_error");
        }
    }
 
    if ('INSERT' == substr(trim($sql), 0, 6))
    {
        $result = mysql_insert_id();
    }
    return $result;
}

then replace with this following code:

function pod_query($sql, $error = 'SQL failed', $results_error = null, $no_results_error = null, $show_error=false)
{
    global $table_prefix;
 
    $sql = str_replace('@wp_', $table_prefix, $sql);
 
    // Check whether the SQL error message will be displayed or not, added by Masino Sinaga, Sept 25, 2009
    if ($show_error==true) {
        $result = mysql_query($sql) or die("Error: $error; SQL: $sql; Response: " . mysql_error());
    } else { 
        $result = mysql_query($sql) or die("Error: $error; Invalid URL or parameter!");
    }
    if (0 < @mysql_num_rows($result))
    {
        if (!empty($results_error))
        {
            die("Error: $results_error");
        }
    }
    else
    {
        if (!empty($no_results_error))
        {
            die("Error: $no_results_error");
        }
    }
 
    if ('INSERT' == substr(trim($sql), 0, 6))
    {
        $result = mysql_insert_id();
    }
    return $result;
}

then save the file.

If you want to display this error message (typically useful when you are in development mode), then assign the fifth parameter ($show_error) with true, aftewards, do not forget to remove the fifth parameter or assign it with false when your website in the live or production-mode.

- The right parameter value case: http://www.openscriptsolution.com/data/bank-in-indonesia/?type=bank&pg=1
- The wrong parameter value case (watch that the parameter value is not numerical data): http://www.openscriptsolution.com/data/bank-in-indonesia/?type=bank&pg=aa

Improving Pagination Feature in Pods CMS of WordPress

Masino Sinaga — Thu, 24 Sep 2009 06:28:35 +0000

Today I saw an improvement about Styling the paging feature created by nikos in Pods CMS Forums. It was an interesting improvement, indeed. Then I applied it on my blog here. I also added the 2 additional links: Previous and Next on the pagination feature, by modifying the pagination_2.php and Pod.class.php file.

So here was I did:

Modified the \pods\core\pagination_2.php file become like this:


 

$page = $this->page;
$rows_per_page = $this->rpp;
$total_rows = $this->getTotalRows();
$total_pages = ceil($total_rows / $rows_per_page);
$type = $this->datatype;
 
$request_uri = "?type=$type&";
foreach ($_GET as $key => $val)
{
  if ('pg' != $key && 'type' != $key && !empty($val))
  {
   $request_uri .= $key . '=' . urlencode($val) . '&';
  }
}
?>
  
 

 
  if($total_pages > 1) :
    echo ''.$label1.' '.$page.' '.$label2.' '.$total_pages.':';
  endif; 
 
  if (1 < $page) :
    if($total_pages > 2) : 
      $prev = $page - 1;
      echo ' .$request_uri.'pg=1" class="prevPage">« '.$label3.' ... ';
      echo ' .$request_uri.'pg='.$prev.'" class="firstPage">« '.$label6.'';
    else : 
      echo ' .$request_uri.'pg=1" class="pageNum firstPage">1';
    endif;
  endif; 
 
  if (1 < ($page - 100)) :
    echo ' .$request_uri.'pg='.($page - 100).'" class="pageNum">'.($page - 100).'';
  endif;
 
  if (1 < ($page - 10)) :
    echo ' .$request_uri.'pg='.($page - 10).'" class="pageNum">'.($page - 10).'';
  endif; 
 
  for ($i = 4; $i > 0; $i--) : 
    if (1 < ($page - $i)) : 
      echo ' .$request_uri.'pg='.($page - $i).'" class="pageNum">'.($page - $i).'';				
    endif;
  endfor;
 
  ?>  echo $page; ?>
 
  for ($i = 1; $i < 5; $i++) :
    if ($total_pages > ($page + $i)) :
      echo ' .$request_uri.'pg='.($page + $i).'" class="pageNum">'.($page + $i).'';
    endif;
  endfor;
 
  if ($total_pages > ($page + 10)) : 		
    echo ' .$request_uri.'pg='.($page + 10).'" class="pageNum">'.($page + 10).'';
  endif;
 
  if ($total_pages > ($page + 100)) :
    echo ' .$request_uri.'pg='.($page + 100).'" class="pageNum">'.($page + 100).'';
  endif; 
 
  if ($page < $total_pages) : 
    if($total_pages > 2) :
      $next = $page + 1;
      echo ' .$request_uri.'pg='.$next.'" class="nextPage">'.$label5.' »';
      echo ' .$request_uri.'pg='.$total_pages.'" class="lastPage"> ... '.$label4.' »';
    else:
      echo ' .$request_uri.'pg='.$total_pages.'" class="pageNum">2';
    endif;
  endif;
 
?>

Open \pods\core\Pods.class.php file, and find this code:

    /*
    ==================================================
    Display the pagination controls
    ==================================================
    */
    function getPagination($label = 'Go to page:')
    {
        if ($this->rpp < $this->getTotalRows())
        {
            include realpath(dirname(__FILE__) . '/pagination.php');
        }
    }
 
    /*

then replace with the following code:

    /*
    ==================================================
    Display the pagination controls
    ==================================================
    */
    //function getPagination($label = 'Go to page:')
    function getPagination($label1 = 'Page', $label2 = 'of', $label3 = 'First', $label4 = 'Last', $label5 = 'Next', $label6 = 'Previous')
    {
        if ($this->rpp < $this->getTotalRows())
        {
            include realpath(dirname(__FILE__) . '/pagination_2.php');
        }
    }
 
    /*

To display the paging, I added to my template or in my PodPages:

 
  // For example, this is for Indonesian language
  echo $Record->getPagination('Halaman:', 'dari', 'Awal', 'Akhir', 'Maju', 'Mundur');
  // For English (default):
  echo $Record->getPagination();
?>

How to Add Custom Record Number in Table List of PodPages

Masino Sinaga — Mon, 21 Sep 2009 13:29:49 +0000

I have just found the way how to add custom record number in the table list of PodPages in WordPress Pods CMS plugin. I optimize the PodPages feature for this purpose by using Bypassing Templates technique. Currently, up to Pods CMS version 1.7.3, you can only use the id field from the table as your record number column. Unfortunately, if you delete one or some of the record(s) from the table, then there will be missing number when you displaying this record number that you get from that id field. Besides that, if you search or filter the certain record, then the record number on the result will not continuously (there will be some missing number). So, here is the solution that I made to fix that problem, by adding the custom record number column based on the number of record in a page or in the table result.

In this example below, I used state data type that currently exists in wp_pod_tbl_state table.

 
get_header(); 
 
$Record = new Pod('state');
$pagelimit = empty($_GET['limit']) ? '10' : $_GET['limit']; 
$Record->findRecords('id ASC', $pagelimit); 
 
if (1 > $Record->getTotalRows()) {
 
} else { 
 
  echo "The List of State
";
  echo "
";
  echo $Record->getFilters('','Filter');
  $total_rows = $Record->getTotalRows();
  echo "Total Record = ".$total_rows."
";
  echo "
";
  echo $Record->getPagination('Page:');
  echo "
";
  echo "
Click on the Name to display its abbreviation.";
  echo "ellpadding='2'>";echo"";$i=1;$pg=empty($_GET['pg'])?'1':$_GET['pg'];while($Record->fetchRecord()){// process the record number$no=$i+($pg-1)*$pagelimit;$abbrev=$Record->get_field('abbrev');echo"";$i++;}echo"
   Record # State Name
  
    
   
  
    
        
      
     ".$no .".  ".$Record->get_field('name')."
    
  
   
";
  echo "
";
  echo $Record->getPagination('Page:');
}
echo '

Back to Previous Page | Back to Index Page
';
 
get_footer(); 
?>

I hope this is helpful.

Add PageLimit as Dynamic Param on Filter Form of Pods Plugin in WordPress

Masino Sinaga — Sat, 19 Sep 2009 16:05:45 +0000

Today I started using Pods CMS plugin in this website. After visitting the official website of Pods CMS, I think this plugin indeed the best one if you want to add the customize page to your WordPress website that contains of the certain data that derived from database without having use Post or Page feature in WordPress website. I have been trying and testing this plugin, until I made a modification in order user can change the maximum record number per page on the Filter form.

Open your \pods\core\list_filters.php file, and find this code:

// Display the search box and submit button
$search = empty($_GET['search']) ? '' : $_GET['search'];
?>
         echo $search; ?>" />
         echo $label; ?>" />

replace with this following code:

// Display the search box and submit button
$search = empty($_GET['search']) ? '' : $_GET['search'];
$pagelimit = empty($_GET['limit']) ? '10' : $_GET['limit'];
?>
     echo $search; ?>" />
     Limit:
    
              
         echo $label; ?>" />

Adjust your PodPages, for exampe:
Before adding pagelimit as dynamic param, here is your PodPages:

 
get_header(); 
$Record = new Pod('state');
echo "States List
";
echo $Record->getFilters();
echo "
";
// Pagelimit as a static param belongs to findRecords() function
$Record->findRecords('name ASC', 10);
$total_rows = $Record->getTotalRows();
echo "Total Record = ".$total_rows."
";
echo $Record->getPagination();
echo "
";
echo "ellpadding='2'>";echo"";echo$Record->showTemplate('state_list');echo"
 Rec# Name
 
 
";
get_footer(); 
?>

After adding this modification, now the pagelimit has become a dynamic parameter, thus visitor can change the maximum record per page on the Form filter. Please compare the PagePod below with the one above:

 
get_header(); 
$Record = new Pod('state');
echo "States List
";
echo $Record->getFilters();
echo "
";
// Now pagelimit as a dynamic parameter on the form
$pagelimit = empty($_GET['limit']) ? '10' : $_GET['limit'];
$Record->findRecords('name ASC', $pagelimit);
$total_rows = $Record->getTotalRows();
echo "Total Record = ".$total_rows."
";
echo $Record->getPagination();
echo "
";
echo "ellpadding='2'>";echo"";echo$Record->showTemplate('state_list');echo"
 Rec# Name
 
 
";
get_footer(); 
?>

Have a nice code!
