Magento – Ajax Not Working in Grid Edit Form (Backend)

formsgridgrid-serlization

I have included a product grid in edit form tab. ( same edit category does ), however when I search the ajax loader doesn't stop and I'm redirected to the main tab.

I can post part of code if needed but I would only if required ( many files involved )

UPDATE:

it looks like the problem is that the param $url passed to the function reload (grid.js) doesn't contains ?isAjax=true

There are quite some tutorials explaining how to add a custom admin grids. Unfortunately some of them are missing the fact that sorting and filtering functionality require additional controller action.

This action is specified by getGridUrl() method of your grid class. The pitfall is that this method is defined in Mage_Adminhtml_Block_Widget_Grid so if you forget to override it you may notice it until you try to sort or filter your grid. Mage_Adminhtml_Block_Widget_Grid::getGridUrl() returns $this->getCurrentUrl() which doesn't make much sense. So obvious move would be to override it with something like this:

public function getGridUrl()
{
    return $this->getUrl('*/*/grid', array('_current'=>true));
}

The simple controller action that will just render a layout will wrap things up:

public function gridAction()
{
    $this->loadLayout();
    $this->renderLayout();
}

Filter Not Working in Grid – Troubleshooting Guide

On the webguys page is a german article about this problem: http://www.webguys.de/magento/turchen-23-pimp-my-produktgrid/

Nicht alle unsere Änderungen werden von Magento übernommen, zum Beispiel funktioniert die Sortierung und Filterung der neuen Attribute nicht.

Das liegt daran, dass unsere Änderungen nach dem Aufruf von _prepareCollection(), in dem die Spalteninfos an die Collection übergeben werden, stattfinden.

Translation:

Not all changes are made by magento, e.g. sorting and filtering of the new attributes doesn't work.

That's because they are made after the _prepareCollection() call, where the informations about the columns are passed to the collection.

protected function _callProtectedMethod($object, $methodName) {
    $reflection = new ReflectionClass($object);
    $method = $reflection->getMethod($methodName);
    $method->setAccessible(true);
    return $method->invoke($object);
}

protected function _modifyProductGrid(Mage_Adminhtml_Block_Catalog_Product_Grid $grid) {
 
    $this->_addUpdatedAtColumn($grid);
    $this->_addColorColumn($grid);
 
    $this->_removeColumn($grid, 'set_name');
    $this->_removeColumn($grid, 'visibility');       

    // reinitialisiert die Spaltensortierung
    $grid->sortColumnsByOrder();
    // reinitialisiert die Sortierung und Filter der Collection
    $this->_callProtectedMethod($grid, '_prepareCollection');               

}

More in the post. I think the source code is quite self explaining and if not, use google (if you don't understand german ;-))

Magento – Save Grid Checkbox Values

You most likely need to generate the secret key when creating the URL to POST to:

Mage::helper("adminhtml")->getUrl("acompany_mymodule/index/index");
$key = Mage::getSingleton('adminhtml/url')
             ->getSecretKey("acompany_mymodule/index/","index");
