An online signup script is randomly missing part of the task. These scripts are involved: sub_signup.php include/cc_proc.php - does the CC (credit card) processing include/user_maint.php - inserts the new subscriber into the database When the CC processing finishes, with the success flag, user_maint.php is included, and a few lines later the createUser($params) function therein is called to create the user. Every mysql_ function in user_maint.php is backstopped with a die() if it fails. But sometimes it appears that the call to this script, or the createUser() function just isn't made. What seems to happen, randomly, is that the script "charges on" so to speak, sending an advisory email to the office manager that there is a new subscriber, and calling sub_signup_thanks.php, which displays a completion message, etc. In all of these cases the credit card processing has succeeded. Sometimes people have tried to sign up two or three times, the card processes, but no addition is made to the database. It's driving us nuts! Any thoughts?
