Registration Form Validation

OK, I finally conquered the Java Validation of the Registraion Form.  It will now validate the Fixed Fields as well as all the auto fields that are set to required.  As I know some of you are eager for this solution, I will give it here, but it will be included in my next release.

To replace the code yourself, open the file event_register_attendees.inc.php (if you don’t have that file in your folder you have an old version, please upgrade to a newer version).  Go to line 109 and look for the ‘<SCRIPT>’.  Select all the text between ‘<SCRIPT> and ‘</SCRIPT>’ (but not the  ’<SCRIPT> and ‘</SCRIPT>’) and delete the existing validation script. 

Next copy and paste the code at the bottom of this post in between the ‘<SCRIPT> and ‘</SCRIPT>’.  Then Save, Upload and try it out.

If you found this helpful, please provide me your comments and if you can any donations would be appreciated.
