JoomFish, add editor to extra fields

Over a year now i started working on sites with Joomla! 2.5 combined with K2 plugin and Joomfish 2.5.1 installed. I noticed that in Joomfish extra fields didn’t appeared like they should, instead they where looking as a JSON string. With little googling i found how to fix this problem here.

Next thing to face was adding the editor to textareas… I added the following code to render the editor to textareas and also to save them correctly to the database, without html code for search.

1. Added the editor to textareas
   Lines: 981, 1068

   $editor =& JFactory::getEditor();
   $output= $editor->display( 'K2ExtraField_'.$extraField->id, $active, '100%', '400', '70', '15',false);
   

2. Added slashes for JavaScript conflicts
   Lines: 665, 843

   $output= str_replace("'","\'",$output);
   

3. Added function to keep search value clean, without html code
   Line: 531

   //this is for saving search
   foreach ($variables as $key => $value) {
    if ((bool) JString::stristr($key, 'K2ExtraField_')) {
     $object = new JObject;
     $object->set('id', JString::substr($key, 13));
     $object->set('value', $value);
     unset($object->_errors);
     $objectsa[] = $object;
    }
   }
   $extra_fields_search = '';
   foreach ($objectsa as $object) {
    $extra_fields_search .= $this->getSearchValue($object->id, $object->value);
    $extra_fields_search .= ' ';
   }
   //search ends here
   //this is for saving extra fields
   foreach ($_POST as $key => $value) {
    if ((bool) JString::stristr($key, 'K2ExtraField_')) {
     $object = new JObject;
     $object->set('id', JString::substr($key, 13));
     $object->set('value', $value);
     unset($object->_errors);
     $objectsb[] = $object;
    }
   }
   $json = new Services_JSON;
   $extra_fields = $json->encode($objectsb);
   //extra fields ends here
   

I’ve attached my source code with the original file from K2

1. Remove extra_fields and extra_fields_search from

   /administrator/components/com_joomfish/contentelements/k2_items.xml

2. Copy k2.php to

   /plugins/system/k2/
