I trying to do an example of overriding a block. I thought I followed the instructions correctly, but nothing happens. Is there an error somewhere?
The block to be overwritten is Mage_Page_Block_Html_Head. I do the rewrite of the block in config.xml:
<config>
<blocks>
<html>
<rewrite>
<head>Hello_Mymodule_Block_Head</head>
</rewrite>
</html>
</blocks>
</config>
Then I create Head.php in: app - code - local - Hello - Mymodule - Block - Head.php.
I copy the getTitle method from the original Head.php into my new Head.php, then I just put in "die()" to see if it works:
class Hello_Mymodule_Block_Head extends Mage_Page_Block_Html_Head {
public function getTitle()
{
die();
if (empty($this->_data['title'])) {
$this->_data['title'] = $this->getDefaultTitle();
}
return strtoupper(htmlspecialchars(html_entity_decode(trim($this->_data['title']), ENT_QUOTES, 'UTF-8')));
}}
Nothing happens, and I don't know how to search for the error. My module is active and working (it shows up in admin)
You have to rewrite block Mage_Page_Block_Html_Head but what you are trying to rewrite is Mage_Block_Html_Head which do not exist at all. change your confix xml to
<config>
<blocks>
<page>
<rewrite>
<html_head>Hello_Mymodule_Block_Head</html_head>
</rewrite>
</page>
</blocks>
</config>
