Adding new attribute to static block(cms/block)

Question

Greetings StackExchange.

I'm not quite sure whether this has been answered before or not. I have done a fair amount of blog / thread searching on this problem/topic.

Is there a way to add a custom attribute to Static Blocks? For example it is possible via. the backend to create a new attribute and add it to a attribute set for products. For categories it has to be done with a small module, a install script and so on.

I have not come across a way of doing this to either of CMS pages or static blocks.

Can somebody help me getting in the right direction?

WHAT I WANT: A dropdown value/attribute for each unique static block, eg "Include, Exclude, Ignore", in the same area as "Status".

Static block

For this, you need to overwrite this class Mage_Adminhtml_Block_Cms_Block_Edit_Form. This class is used to add fieldsets and fields for cms_block. Take a look on the _prepareForm() method inside it.

If you put this code, just after Title field,

 $fieldset->addField('sub_title', 'text', array(
 'name' => 'sub_title',
 'label' => Mage::helper('cms')->__('Sub Title'),
 'title' => Mage::helper('cms')->__('Sub Title'),
 'required' => true,
 ));

you can see your sub-title text field in static blocks. However Do not edit a core file directly. You need to write a custom module that should overwrite this class. Your Module config file should contain this code

File : app/code/local/Namespace/Module/etc/config.xml

<config> 
 <global>
 <blocks>
 <adminhtml>
 <rewrite>
 <cms_block_edit_form>Namespace_Module_Block_Adminhtml_Cms_Block_Edit_Form</cms_block_edit_form>
 </rewrite> 
 </adminhtml>
 </blocks>
 </global>
</config>

This will allow you to rewrite the class. What you need to do now is define the rewrite class now and in there you need to rewrite _prepareForm(). It should some what look like this.

Location : app/code/local/Namespace/Module/Block/Adminhtml/Cms/Block/Edit/Form.php

<?php
class Namespace_Module_Block_Adminhtml_Cms_Block_Edit_Form extends Mage_Adminhtml_Block_Cms_Block_Edit_Form {
 protected function _prepareForm()
 {
 //put all the code inside parent class here 
 //then place the below content in appropriate place
 $fieldset->addField('sub_title', 'text', array(
 'name' => 'sub_title',
 'label' => Mage::helper('cms')->__('Sub Title'),
 'title' => Mage::helper('cms')->__('Sub Title'),
 'required' => true,
 ));
 return parent::_prepareForm();
 }
}

Try based on this idea

EDIT

Please note, it will allow you to put new field in cms > block, howver to save this, you need to define model for your module. You have two options. Add a new field to save your new field in Cms> Block table or create your own table and store this value in that field along with the referene to cms>block table. This is out of box and you should implement it your own way.

• Andreas Therkildsen: Thanks alot! I've added a table to the cms_block table.
