I'm aware that it's possible to call the HTML value by: {{customVar code=custom_variable_code}}

Question is simple: Is it possible to receive plain value of custom variable in email template (Magento 1.9.2.0) with some statement like: {{customVar code=custom_variable_code|plain}}? If it's not, are there any tips to get something like that to work?

It is but it'll require some coding.

In a nutshell this is how an email is sent

$template  = Mage::getModel('core/email_template')->loadDefault('[email identifier]');                                  

$template->send('[email protected]','John Doe', array(
   'myvar' => 'foo',
   'myvar2' => 'bar',
));

now we can access the variables using {{var myvar}} and {{var myvar2}}

So to inject your values you'll need to make modifications to the array with variables injected into the send method.

It depends on what email you want to change

  • I was thinking about using it in almost all email templates - to be more specific in their subjects. But as I see the more quicker and cleaner approach is to just create dedicated for emails custom variable with text value entered in html – then it's accessible everywhere without any reinventing of the wheel. Only hiccup is that there will be two same custom variables but one with i.e. email prefix.

  • @versedi hold one sec, let me check if there is an event you can use to inject them into every email\

  • ok say there isn't an event but you could rewrite Mage_Core_Model_Email_Template_Filter from a custom module setting your vars in the _construct method or rewrite Mage_Core_Model_Email_Template setting them in the send method. It ain't perfect but it'll get the job done
