search function not working (server side processing)

Hi,

I've implemented a PHP/mysqli server side solution that is working almost perfectly fine. The only thing, for now, that isn't working is the search box.

I've taken the code from there -> http://datatables.net/development/server-side/php_mysqli

I've also searched in the forums here and found some potential solutions/workaround yet none were really what I was looking for.

Here's the 2 JSON response I'm getting

#1 When table is first generated

    ]
}

and #2, when I get the error (please note that the error appears the minute I type 1 character in the search box):

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(`created_date` LIKE '%t%' OR `name` LIKE '%t%' OR `reference` LIKE '%t%' OR `co' at line 2

From my investigation, it appears that the code generating the error is the following:

/**
 * Filtering
 * NOTE this does not match the built-in DataTables filtering which does it
 * word by word on any field. It's possible to do here, but concerned about efficiency
 * on very large tables, and MySQL's regex functionality is very limited
 */
$iColumnCount = count($aColumns);
 
if ( isset($input['sSearch']) && $input['sSearch'] != "" ) {
    $aFilteringRules = array();
    for ( $i=0 ; $i<$iColumnCount ; $i++ ) {
        if ( isset($input['bSearchable_'.$i]) && $input['bSearchable_'.$i] == 'true' ) {
            $aFilteringRules[] = "`".$aColumns[$i]."` LIKE '%".$db->real_escape_string( $input['sSearch'] )."%'";
        }
    }
    if (!empty($aFilteringRules)) {
        $aFilteringRules = array('('.implode(" OR ", $aFilteringRules).')');
    }
}

Any hints or help that would help me resolve this will be greatly appreciated. Let me know if there is any more information I can provide to help with this matter.

Cheers
