[SOLVED] REGEX Request

[n3ightjay]

Hey Guys ... never used regex and don't really get it (yet fingers crossed) but i need to check a string meets a length and prefix expression.

 

i need the string to match:

 

"SNPLXXXXX" where the "X"'s are integers and "SNPL" is the manditory prefix

 

what i know is (is not much):

 

if (eregi("", $_POST['barCode'])){

[sasa]

try

<?php
$string = trim($_POST['barCode']);
//$string = 'SNPL12345';
echo preg_match('/^SNPL[0-9]{5,5}$/',$string) ? 'true' : 'false';
?>

Sasa, when you need 5 digits, you don't need to state an equal minimum and a maximum.. simply use {5}.

 

To the OP, try to learn preg (part of Perl Compatible Regular Expressions) instead of ereg. As of PHP6, POSIX (which ereg is part of) will not be supported within the PHP6 core by default. I believe it will only be available as an extension.

 

There are resources here at PHPFreaks to help you out with that.

 

Cheers,
