alrighty let me explain what I'm trying to do. I made an online form where a user can choose a month and a week then hit submit. The php page it POST's to turns the to variables into a string
$mon = $_POST[month];
$week = $_POST[week];
$getfile = $mon$week.php;
Pretty darn easy right? Well the problem is I don't know how to write a check function that makes sure the file exists before php tries to include it. Basically when the user enters a month and week that I don't have a file for I get a long php error message. I'd like to set it up so it just displays a message "Sorry we do not have a file for that month and week". Any help would be greatly appreciated.
