[Resolved] $REQUEST and Zero Values

[spyderman]

I have a Salary input field in my html form, which accepts a number value and the default is 0. I also have a data validation class which checks if required fields have data.

In my case, Salary is a required field and 0 (zero) is a valid input value. The problem I'm experiencing is, when I get 0 input value for Salary, through the $REQUEST variable, and pass it into my data validation routine, the $REQUEST variable returns null or empty, causing my data validation routine to think that nothing was entered.

So my question is, is there a way to determine if 0 was entered or if the field was left blank?

The integer "0" is commonly associated with the FALSE constant/return code in PHP.

I would need to see your validator, but somewhere you probably have "if($input == NULL)" or something of the sort. Do a strict comparison there instead; "if($input === NULL)".

If you can't figure it out, paste your validator code in here.
