Re: Clear field after validation failure

Calvin: data is being written to the value="" of the tag - so its not the browser doing it...

cricket: form is an add form - there is no reading going on, no else....

i've even tried explicitly unsetting the keys for $this->data that i want to clear but it still finds its way into the form some how....

Its on a signup form using Auth Component if that makes any difference? (though the form isn't bound to the user table, i'm performing validation on dummy fields then in the model writing to the correct fields if the dummy fields pass validation).

Are you sure that you're not overwriting it yourself? A common mistake
is to do something like this:

public function edit($id = null)
{
       if (!empty($this->data))
       {
               // pseudocode
               if (validate + save)
               {
                       // redirect
               }
       }

       // if above fails you'll be here

       $this->data = $this->Foo->read(null, $id);
}

The read() line should be wrapped in an else block so that it's not
called if data was submitted.
