[SOLVED] validating variable

[daveh33]

I have a variable $t - I need to validate it so it allows: -

32-digits, alpha numeric and in the range A-F and 0-9. All letters will be in CAPITALS.

 

and if not display an error message - how do I do this??

Do an IF Statement for each requirement.

 

Verify against length, type and range.  Caps is really not an issue because you can just convert everything to uppercase.

 

Doing something with HEX?

Simple regular experssion:

 

<?php

if(!preg_match("/^[A-F0-9]{32}$/", $t))
echo "Invalid";

?>

 

 

Orio.
