validate() function within block controllers

Permalink
Hi

I'm looking to run validation within my block controller but I'm struggling to access variables.

In my code I have a field called "start_stack". This is just one example of many, that I'm wanting to access in my validate() function.

I've used the following code to attempt to debug:
public function validate() {
      $error = Loader::helper('validation/error');
      $error->add('stack_start contents: ' . $stack_start);
      $error->add('stack_start obj contents: ' . $this->stack_start);
      if($error->has()) {
         return $error;
      }
   }


Both the variables $stack_start and $this->stack_start return nothing.

Why are the variables accessible at this start of the execution?

Thanks.

At this point the variables are still request parameters. Try:
$_POST['start_stack']

If anyone comes across this, the validate method is passed in the arguments of the fields. So you can get them via
/**
 * $args is an array of form fields
 * $error is a ValidationHelperObject
 * if $error contains no errors the field
 * with submit successfully but if there are
 * errors the user will get a dialog with
 * them listed.
 */
public function validate($args) {
  $error = Loader::helper('validation/error');
  if(ctype_digit($args['something']) === false) {
    $error->add(t('Something must me a number'));
  }
  return $error;
}

God it's strange you bump this now. Literally 10 minutes ago I asked aghouseh about this again (silly me forgetting stuff).

Cheers mkly.
