Any suggestions for input masks

[gecko]

Is it possible in PHP to validate user input using a specific input mask?

 

I've searched everywhere, and the only way I know is to use Javascript, but I thought I'd just check if there are anyother ways.

 

I'm wanting to ensure that users input the correct data in the right format. An example would be a username, set to 'u01234' for exmaple. So I would need to make an input mask that only allowed one text character followed by 4 digits.

 

Any suggestions would be VERY helpful

Sure, in fact it's better to have some kind of server-side validation due to the fact that users can disable JS.

 

You can use something like:

 

$d = "u12324";
if(preg_match("/^[a-z]\d{4}$/i", $d))
{
   echo "success";
}
else
{
   echo "fail";
}
?>
