We'll give it the class prefix "My_Decorator", and the class itself will be in the file "My/Decorator/Label.php". check my blog Zend_Form_Element encapsulates single form elements, with the following areas of responsibility: validation (is submitted data valid?) capturing of validation error codes and messages filtering (how is the element escaped or normalized Expects a string value indicating the class for the object being composed @ComposedObject("Namespace\Model\ComposedObject") or an array to compose a collection: @ComposedObject({ "target_object":"Namespace\Model\ComposedCollection", "is_collection":"true", "options":{"count":2}}) target_object is the element to compose, is_collection If the line shown is used in the init() method, in the same way shown for the setErrors(), in case of error, the custom message will be shown as many times Zend Form Element Select
