Magento 1.9 – How to Override /app/code/core/Mage/Catalog/Block/Product/List/Random.php

blocksmagento-1.9overridesrwd-theme

I have been trying to override the Random.php file and have looked at inchoo and another method here. When I do the change on the core file the change takes effect immediately, but when I created the override, the modification do not take effect.

I am trying to override
/app/code/core/Mage/Catalog/Block/Product/List/Random.php. I have created /app/code/local/MyFolder/Catalog/Block/Product/List/Random.php (the modified file).

I have also changed the class name in my override file, to class MyFolder_Catalog_Block_Product_List_Random extends Mage_Catalog_Block_Product_List

I can't figure out how to properly modify app/etc/config.xml file? This is what I have so far.

<config>
 <global>
    ...
    <models>
    ...
    </models>
    <blocks>
        <catalog>
            <rewrite>
                <product_list>MyFolder_Catalog_Block_Product_List_Random</product_list>
            </rewrite>
        </catalog>
    </blocks>           
 </global>
</config>

OK it's now functioning.
Changed from: 

<rewrite>
    <product_list>MyFolder_Catalog_Block_Product_List_Random</product_list>
</rewrite>

To: 

<rewrite>
    <product_list_random>MyFolder_Catalog_Block_Product_List_Random</product_list_random>
</rewrite>

Now I am not sure if there are any other places that needs updating?

Best Answer

Your rewrite path should be global/blocks/catalog/rewrite/product_list_random.

Also, you should not be making this entry in app/etc/config.xml, because this change will be lost in an upgrade. Better to register a new module in app/etc/modules and add this configuration directive to your module's config file.
