I'm experimenting with Zend_Form right now, and am trying to integrate a custom validation routine on a form field.

I have created a file called TestVal.php and saved it in My/Validate/ to match this class name:

class My_Validate_TestVal extends Zend_Validate_Abstract
{
...

It has a single isValid method which does a silly test on its value and returns a boolean.

My difficulty is in calling this thing:

In the form controller, I have this code:
//add prefix to all elements
$this->addElementPrefixPath('My_Validate','My/Validate/','validate');


$testing = new Zend_Form_Element_Text('testing');
$testing->setLabel('Test Val')
->setRequired(true);

$testing->addValidator('TestVal');

$testing->setValidators($validators);

//etc...

Running this code generates this error:

Error: Plugin by name TestVal was not found in the registry.

Note that the My/ folder is underneath the application root and is in the include path.

Thanks for any assistance.

If I add the prefix to the element, it works, but to the form, it doesn't.

For example,

$testing = new Zend_Form_Element_Text('testing');
$testing->setLabel('Test Val')
->setRequired(true);

//new code
$testing->addPrefixPath('My','My/');

$testing->addValidator('TestVal');

$testing->setValidators($validators);

Works. Can anyone tell me why it doesn't work when I add it to form itself?

what is $validators content?

The $validators was a cut-and-paste error and was not in my final form code (sorry about that).

Here is the form code that works:

$testing = new Zend_Form_Element_Text('testing');
$testing->setLabel('Test Value')
->setRequired(true);

$testing->addPrefixPath('My','My/');

$testing->addValidator('TestVal');

Adding the prefixPath to the element runs the custom validator perfectly, but adding it to the form as in the previous message it doesn't work.
