Calling custom Block in the transactional emails

Question

This is how I call a custom phtml file in the trans.email content:

{{block type='core/template' area='frontend' template='foldername/myfile.phtml' order=$order}}

and its working perfect. But I want to include a block where I will do the logic and in the phtml file I just want to call the needed function from my block. I tried the following:

{{block type='mynamespace_mymodule/email_pdflink' area='frontend' template='foldername/myfile.phtml' order=$order}}

and this is the content of the block:

class Mynamespace_Mymodule_Block_Email_Pdflink extends Mage_Core_Block_Template
{
    public function test()
    {
        return 13;
    }
}

and the content of the myfile.phtml:

$this->test();

Even if a write a simple html code in the myfile.phtml file it doesn't show up in the content of my trans. email. Any idea how to solve this ? thx

Answer 1

What you need to do is allow the custom class directive for your block in System > Permissions > Blocks

Just add the class directive and set to 1.

I was implementing something similar recently and it has to do with a recentish patch (SUPEE-6788). Spent some time testing and going crazy until I realized this was the issue.

More information can be found on the mage site about the patch https://magento.com/security/patches/supee-6788-technical-details
