im using this form of luhns algorithm <?php /* Luhn algorithm number checker - (c) 2005-2008 - planzero.org * * This code has been released into the public domain, however please * * give credit to the original author where possible. */ function luhn_check($number) { // Strip any non-digits (useful for credit card numbers with spaces and hyphens) $number=preg_replace('/\D/', '', $number); // Set the string length and parity $number_length=strlen($number); $parity=$number_length % 2; // Loop through each digit and do the maths $total=0; for ($i=0; $i<$number_length; $i++) { $digit=$number[$i]; // Multiply alternate digits by two if ($i % 2 == $parity) { $digit*=2; // If the sum is two digits, add them together (in effect) if ($digit > 9) { $digit-=9; } } // Total up the digits $total+=$digit; } // If the total mod 10 equals 0, the number is valid return ($total % 10 == 0) ? TRUE : FALSE; } ?> Only problem is when im using it doesnt seem to be validating the input. How about would you guys go about trying to use it? if the text box were trying to use has these values name=$creditvalue

TRUE : FALSE; } ?> im trying to use it like this but its not working. if ($errorluhn) $errorluhn = "luhn validation"; $luhn = isset($_POST['luhn']) ? trim($_POST['luhn']) : ''; if (luhn_check($luhn) $errorluhn = true; if (luhn_check($luhn) $errorluhn = true; that line is the acutally line where im getting trouble with

When im adding to my shopping cart. It is being display as an empty value, inside quantity when its really a 1. So then the incremental is then out of wack the next time i add a item. so if instead of it being display as 2 it is being displayed as 1. Because of the fact that its starting off as NULL.
-
ahh sorry if i didnt explain myself well guys. i tend to do that sometimes. I have a shopping cart and when i add a item it displays item name : (Nothing here as 1) : price then when i click add again it adds it as item name : 1 : price where i want 1 to be a incremental

I have a shopping cart, and everytime i go to add the same item to a cart it adds +1 to quanity the only problem is. I dont know how to refresh this so that session is only set for say 1 hour then reset or something similar to that.
