empty and zero as a string
<p>How do I write an if condition that will evaluate a zero as not empty? I'm writing a validation script and if the field is blank, I throw an error. In the case of a select with numerical values that start with 0 (zero), that should not considered to be empty. The manual states that a string 0 is considered to be empty and returns false. If I change empty to !isset, the zero works but the other textboxes that are truly empty pass validation. How do I write this to handle my case?</p>
