Adding custom attribute to a Magento CMS page

Sometimes we need to add a custom attribute to a CMS page. I’ll try to describe how we can do this as simply as possible using a custom module with observers.

First of all, you should create your module registration file under app/etc/modules:

<?xml version="1.0"?>

after this, we need to create a folder that contains our own module under app/code/local, in my case it is app/code/local/Atwix/CMS. Next step is to create module’s configuration file (app/code/local/Atwix/CMS/etc/config.xml):

<?xml version="1.0"?>

IMPORTANT: we need to add a column ‘content_custom’ to the ‘cms_page’ table. That can be done using Magento install scripts (read how to create your own installer here)
if you`re using Magento Enterprise, you should add a column ‘content_custom’ to the ‘enterprise_cms_page_revision’ table as well.

and finally, create Observer file (app/code/local/Atwix/CMS/Model/Observer.php):


class Atwix_CMS_Model_Observer
    public function cmsField($observer)
        //get CMS model with data
        $model = Mage::registry('cms_page');
        //get form instance
        $form = $observer->getForm();
        //create new custom fieldset 'atwix_content_fieldset'
        $fieldset = $form->addFieldset('atwix_content_fieldset', array('legend'=>Mage::helper('cms')->__('Custom'),'class'=>'fieldset-wide'));
        //add new field
        $fieldset->addField('content_custom', 'text', array(
            'name'      => 'content_custom',
            'label'     => Mage::helper('cms')->__('Content Custom'),
            'title'     => Mage::helper('cms')->__('Content Custom'),
            'disabled'  => false,
            //set field value
            'value'     => $model->getContentCustom()


That’s all folks. Hope this article is helpful.
