Zend Framework “documentation” dosn’t say much about validating single checkboxes. If you need to do this, say for a terms ang conditions agreement or something, you have to check that the value is greaterthan zero.
To do this, add a validator like this:
$e =new Zend_Form_Element_Checkbox('tnc');
$e->addValidator('GreaterThan', false, array(0));
And validate your form in the controller as usual
if ($form->isValid($request->getPost())) {
Thanks to Rob Knight for adding how to do this in the bug tracker. http://framework.zend.com/issues/browse/ZF-5920
Update.
If you want to suppress the silly error message that zend gives:
* ‘0′ is not greater than ”
Then do this:
$validator = new Zend_Validate_GreaterThan(false, array(0));
$validator->setMessage(”,
Zend_Validate_GreaterThan::NOT_GREATER);
$e->addValidator($validator, false, array(0));
Hey,
To overcome this problem. I used the the below code;
$terms =
$this->createElement(‘checkBox’, ‘terms’, array(
‘required’ => true,
‘checkedValue’ => ‘1′,
‘uncheckedValue’ => ‘0′
))
->addValidator(‘GreaterThan’, false, array(0))
->addErrorMessage(“Please agree with terms and conditions.”);
