Protype ajax validation problem

[eluser]mdowns[/eluser]
Have you checked what the actual value of $this->obj->input->post('value') is?

Also, have you tried using trim instead of preg_match (seems a bit overkill for just required field validation)?

Code:

function required(){
    $myinput = trim($this->obj->input->post('value'));
    if(empty($myinput) || $myinput == "")
    {
        print "This field is required.";
    }
}
