Zend_Validate concerns

nwim · #1 (**permalink**) 05-09-2008, 04:57 PM

Hi,
Can anyone tell me if I can make use of Zend_Validate classes if I am not using Zend_Form to handle the forms? It would be nice if you could give some examples too...

Moreover, if I am not using Zend_Form in mvc how do I handle the forms (where smarty template is used)?

Please help..

Hi,
yes, you can use Zend_Validate without Zend_Form.

Zend_Validate

Hi Martin,

Thanks for the reply. Can you give me an example of how to implement zend_validate with smarty?

Anyone else have any idea on how to do it? Please help..

Hi, I've never used Smarty and ZF together, so I have no idea how to do it.

hi nwim,

form handling doesn't need to be acomplished by Zend_Form and it doesn't matter what templating system you're using (either Zend_View or Smarty, etc.).

all you need to do is eg.:

PHP Code:


			
class IndexController
{
   public function registerAction
   {
      $request = $this->getRequest();
      if ($request->isPost()) {
         //fragment of code eclosed by this if clause will execute only if there is any post data send by a form
         $errors = array();
         //if u want to retrieve form field do as follows ('username' is example field name)
         //it is prefered way to $username = $_POST['username']
         $username = $request->getPost('username');
         //now if you want to validate for 'username' length
         $validator = new Zend_Validate_StringLength(8);
         if ($validator->isValid($username)) {
            // user name appears to be valid
         } else {
            // user name is invalid; save the reason
            foreach ($validator->getMessages() as $messageId => $message) {
               $errors['username'] = "Validation failure '$messageId': $message";
            }
         }
      // make errors array available to your view
      $this->view->errors = $errors;
      }
   }
}

I hope this example gave you a little bit of understanding on form validating, however there is much more to know, like validator chains

Hi Kuba,
Thanks a lot for the info and the sample code. It was great help. I used your sample code for validating username filed in my registration form. I just added the following line
$this->view->title = "Submit Success"; just before the
$request = $this->getRequest();....rest of the codes are same as the sample code.

But, the validation did not occur. Whether I enter or do not enter any data in the username field, it does not give any error and takes me to the Add Success page. I think I am missing something here...Could you please help me with this?
