How can I output HTML from a Zend Validation Error?

Answer 1

You have to pass the configuration option 'escape' = false to the Zend_Form_Decorator_Errors().

Mostly this one is loaded automatically so then you have to request it.

$zendelement->getDecorator('Zend_Form_Decorator_Errors')->setOption('escape', false);

Answer 2

On version 1.7 this is the correct way of accessing the validator and disable the escaping:

$zendelement->getDecorator('Errors')->setOption('escape', false);
