If you want to add a block after the price on the category page, and for this implementation, you can use the observer core_block_abstract_to_html_before.
You can implement the logic with the below steps:
File path: app/code/local/{namespace}/{yourmodule}/etc/config.xml
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
<?xml version="1.0"?> <config> <global> <!-- ... --> <models> <namespace_modulename> <class>Namespace_Modulename_Model</class> </namespace_modulename> </models> </global> <frontend> <events> <core_block_abstract_to_html_before> <observers> <namespace_modulename> <type>model</type> <class>namespace_modulename/observer</class> <method>insertBlock</method> </namespace_modulename> </observers> </core_block_abstract_to_html_before> </events> </frontend> </config> |
The next step is creating the observer and your template file.
File path: app/code/local/{namespace}/{yourmodule}/Model/Observer.php
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
<?php class Namespace_Modulename_Model_Observer { public function insertBlock($observer) { /** @var $_block Mage_Core_Block_Abstract */ /*Get block instance*/ $_block = $observer->getBlock(); /*get Block type*/ $_type = $_block->getType(); /*Check block type*/ if ($_type == 'catalog/product_price') { /*Clone block instance*/ $_child = clone $_block; /*set another type for block*/ $_child->setType('test/block'); /*set child for block*/ $_block->setChild('child', $_child); /*set our template*/ $_block->setTemplate('filename.phtml'); } } } ?> |
You can add the template to app/design/frontend/<package>/<theme>/filename.phtml .
And finally, here is a template filename.phtml code:

<?php echo $this->getChildHtml('child') ?> |
