Problem between 2 versions of PHP, code works with one version but not the other Options

[CharlesEF]

Hi All,

I'm new to PHP and have run into a problem I can't seem to find/fix. I'm hoping someone here can point me in the right direction.

I have a contact form that works fine when run with PHP v5.2.17
When I update PHP to v5.3.13 the form no longer works (my hosting site allows me to switch). The validation of the 'Captcha image' always fails.

I have looked at the code but I can't see anything wrong, but I am real new to PHP.

I have a test site for this contact form here. My site is set to use PHP v5.3.13 so anyone will get the same error I get.

I hope someone can point me in the right direction to fix this problem.


Thank you for any help,

Charles

PS: I have used ini_set('display_errors', 'On'); and error_reporting(E_ALL); but I can't see any error related to 'Captcha image'. I do see other errors like undefined variables.

Attached is the zip file of the contact form:  image_captcha_1.zip ( 38.19k ) Number of downloads: 362

I get a captcha validation failure already in the javascript, AFAICS the form is never submitted --or is the captcha value sent with Ajax? Try to make the PHP script print out in clear text which captcha value it's expecting, and what it actually gets.

There are quite a few changes between your two PHP versions: http://www.php.net/ChangeLog-5.php

Personally I think captchas are an annoyance. I'd try javascript "encryption" of the server-side script's URL instead, or adding a hidden honeypot form field (that only spambots but not real users will fill in).

Since the problem shows up only when I change PHP versions I never looked at any javascript code. I will see what I can find.


Thanks for the input,

Charles

I found the problem and just want to report the fix.

After wracking my brain going over the code the fix turned out to be simple. The problem was the 'session.save_path' setting in the php.ini file. The web host path was wrong and I just put in a valid path and the contact form now works as it should, under both versions of PHP.

Hope this helps someone else.
