I am using joomla 2.5, I am working on custom component of joomla . I have created the form in backend admin page. what i need is , i want to save the post data of form in params row of that component in database of #_extensions.
Here is my tables/component.php
<?php defined('_JEXEC') or die('Restricted access');jimport('joomla.database.table');
class componentTablecomponent extends JTable {
function __construct(&$db) { parent::__construct('#__extensions', 'extension_id', $db); } public function bind($array, $ignore = '') { if (isset($array['params']) && is_array($array['params'])) { // Convert the params field to a string. $parameter = new JRegistry; $parameter->loadArray($array['params']); $array['params'] = (string)$parameter; } return parent::bind($array, $ignore); } public function load($pk = null, $reset = true) { if (parent::load($pk, $reset)) { // Convert the params field to a registry. $params = new JRegistry; $params->loadJSON($this->params); $this->params = $params; return true; } else { return false; } } public function store() {parent::store(null);
}
}
Instead of saving the $data in params row of that component . This code is creating new empty rows in that table(data is saving in those params field).
Here is my save() function in controllers/component.php
public function save()
{ // Check for request forgeries. JSession::checkToken() or jexit(JText::_('JINVALID_TOKEN')); // Check if the user is authorized to do this. if (!JFactory::getUser()->authorise('core.admin')) { `JFactory::getApplication()->redirect('index.php',JText::_('JERROR_ALERTNOAUTHOR'));` return; } // Initialise variables. $app = JFactory::getApplication(); $model = $this->getModel('component'); $form = $model->getForm(); $data = JRequest::getVar('jform', array(), 'post', 'array'); print_r($data); // Validate the posted data. $return = $model->validate($form, $data); // Check for validation errors. if ($return === false) { // Get the validation messages. $errors = $model->getErrors(); // Push up to three validation messages out to the user. for ($i = 0, $n = count($errors); $i < $n && $i < 3; $i++) { if ($errors[$i] instanceof Exception) { $app->enqueueMessage($errors[$i]->getMessage(), 'warning'); } else { $app->enqueueMessage($errors[$i], 'warning'); } } // Redirect back to the edit screen. $this->setRedirect(JRoute::_('somelink',false)); return false; } // Attempt to save the configuration. $data = $return; $return = $model->save($data); // Check the return value. if ($return === false) { // Save failed, go back to the screen and display a notice. $message = JText::sprintf('JERROR_SAVE_FAILED', $model->getError()); $this->setRedirect('index.php/somelink','error'); return false; } // Set the success message. $message = JText::_('COM_CONFIG_SAVE_SUCCESS'); // Set the redirect based on the task. switch ($this->getTask()) { case 'apply': $this->setRedirect('somelink',$message); break; case 'cancel': case 'save': default: $this->setRedirect('index.php', $message); break; } return true; }
models/component.php
public function save($data) {
parent::save($data); return true;
}
I thinks these codes are enough . I can add more codes if you need.
I have come up with a solution . it works for me . By using this method you can control save () functions i.e. you can run your custom php scripts on save, apply toolbar buttons.
I copied save(),save($data), store($updateNulls = false) functions from com_config component , I have copied the layout from component view . Removed the buttons. Added toolbar buttons in .html.php file.
