Question

I have created a Magento admin module with it’s own menu and page in the back-end, and am trying to recreate how CMS->Pages lists every page in it’s grid on my own page, then add my own column.

So far, after switching on template hints for the admin section, I have seen that the original Magento CMS section template is loaded from adminhtml\default\default\template\widget/grid.phtml.

I have copied the contents of this file to my page, but of course, the $this reference that the original uses doesn’t have the same loaded classes/data asociated with it on my own module page.

Can anyone tell me if I’m along the right lines with this, or how I might achieve the same effect as CMS->Pages, but on my own page and adding my own column?

To accomplish this you can create a custom module that extend /app/code/core/Mage/Adminhtml/Block/Cms/Block/Grid.php

Assuming that you’re adding a database field to cms table

Create /app/code/local/RWS/CmsGrid/etc/config.xml

<global>
   <blocks>
      <adminhtml>
        <rewrite>
          <cms_block_grid>RWS_CmsGrid_Block_Cms_Block_Grid</cms_block_grid>
        </rewrite>
      </adminhtml>
   </blocks>
</global>

Create /app/code/local/RWS/CmsGrid/Block/Cms/Block/Grid.php

class RWS_CmsGrid_Block_Cms_Block_Grid extends Mage_Adminhtml_Block_Cms_Block_Grid
{

   protected function _prepareColumns()
   {

      $this->addColumn('xxxxxx', array(
          'header'    => Mage::helper('cms')->__('Xxxxx'),
          'align'     => 'left',
          'index'     => 'title',
     ));
     ..........
