Zend Form - Adding Custom Error Messges to element

Custom error messages can be added to a form element:

The following shows how to add custom error message to a select element

$countryList = array("0" => "select" ,"1" => "Canada", "2" => "India", "3" => "America");
$countries = new Zend_Form_Element_Select('country');
$countries->setLabel("Country")
     ->setRequired(true)
     ->addFilter('Int')     
     ->addMultiOptions($countryList)
     ->addValidator('GreaterThan',false, array("min"=>1, "messages" => array("notGreaterThan"=>"country is required")));

validator name = GreaterThan
message for = notGreaterThan ( get it from validator library file or api doc)

The customr error message will display now.
