Validating External Forms

Permalink
Hi,

Anyone got an example of this?

for example in my form

<div class="form-field">
<?php echo $form->label('email', 'Email address');
echo $form->text('email'); ?>
</div>

How would I validate this? Something like

echo $form->text('email', required); ?>

If you are using an External Form block you can validate on the server side. So the action in your form would be something like 

$this->action('do_contact');


then in your controller you would have the action_do_contact function where you could do your validation 

$e = Loader::helper('validation/error');
if (eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $_POST['email'])) {
   $email = $_POST['email'];
} else {
   $e->add("Please include a valid email address.");
}
if (!$e->has()) {
   //there are no errors
} else {
   $this->set('error', $e);
}


and then back on your form page you could handle the errors with something like this

if (isset($error) && $error != '') {
   if ($error instanceof Exception) {
      $_error[] = $error->getMessage();
   } else if ($error instanceof ValidationErrorHelper) {
      $_error = $error->getList();
   } else if (is_array($error)) {
      $_error = $error;
   } else if (is_string($error)) {
      $_error[] = $error;
   }
   echo '<ul style="color: red;">';
   foreach($_error as $e) 
      echo '<li>'.$e.'</li>';
   echo '</ul>';
}

That looks great have you validated the captcha?

<?php $captcha = Loader::helper('validation/captcha');?>
<?php $captcha->display(); ?>
<?php $captcha->showInput(); ?>
