Occasional 403 error

[GJim]

I have a form on a client site:
http://www.rmaba.org/rmbpf/fi-submission-form.html

This form was used, last year, with no reported issues. This year, some submissions (so far 2 of 7) generate a ‘403 error’ page instead of a ‘thank-you’ for a successful submission.

I believe this to be a .php issue, not .html.

The .php code is formmail.php from tectite.com (code provided upon request). Tectite seems to have discontinued support for their code. I know that I could probably find some other form-processing code, but we are now into a time-period where I’m hesitant to do so for this year - exhibitors have already been told to use this form.

I can’t find anything in common, between the failed submissions - the fact that some info is accepted, some is rejected is most puzzling.

Error is not related to a particular system nor OS, not related to a particular browser - just that some data is not accepted - there is some evidence that the error is related to the ‘Description’ field.

Any suggestions/help greatly appreciated.

If you wish to test the form, please include ‘Performing a test for G-Jim’ in the message block.

I had a quick look at your form. I don’t know who made it, but you’re sending a lot of stuff that doesn’t need to be sent. It can be easily be gathered on the processing page. You really only need 3 of those hidden inputs, required and env_report and derive_fields. The rest can be moved to the php page.

As for having people using it currently, if you code it right, they’ll never notice the switch. All you’re doing is changing the php part of it.

Its possible that with a seriously long description, it might be overloading things. After all, its sending all of that information through a url.
