In order to support file uploads, your <form> tag should have enctype="multipart/form-data"
Most likely the form isn't updating because it is failing validation. Maybe you deleted a field that was marked as required. When that happens you may not even see the error and it becomes difficult to debug.
Update this:
if ($WAFV_Errors != "") {
PostResult($WAFV_Redirect,$WAFV_Errors,"home");
}
To:
if ($WAFV_Errors != "") {
die($WAFV_Errors);
PostResult($WAFV_Redirect,$WAFV_Errors,"home");
}
That will write the error number of the line that is failing validation and allow you to figure out which one it is to correct it. It will have a number 1-67 to match the numbers at the end of each validation check above that you can use to find the correct validation that is failing.
