$_SESSION problem

Hello,

I’ve got a problem.

For a captcha script I am writing I need to start a session. The captcha script generates a picture (png) en starts a session with the code in it.
Now I can’t figure out how to start this session because after submitting the form print_r($_SESSION) is empty.
I downloaded modxapi.php to solve the problem, but it doesn’t work yet.

The only way it will work is if I log in on the manager. But that’s not the solution because I want to use the captcha in a contactform, accessable for anyone who visit the website.

And.. veriword doesn’t work for me..

Anyone?

Thanks, Gr Pieter...!

There is captcha built into MODx.
If you use eForm you can turn it on using one of the parameters.

If you want to use the MODx session, you need to author your script as a MODx Snippet and serve it as a MODx Resource. Otherwise, you’ll have to find a way to include the manager/includes/config.inc.php file and use the startCMSSession() function defined in that file.

I did that.. tried 2 options:

1. include modxapi.php with following code:

include_once($_SERVER['DOCUMENT_ROOT'] . '/modxapi.php');
$modx = new MODxAPI();
$modx->connect();
$modx->startSession();
$modx->getSettings();

2. include config.inc.php with following code:

include_once($_SERVER['DOCUMENT_ROOT'] . '/manager/includes/config.inc.php');
startCMSSession();

Both ways don’t work, accept when you login to the manager.

Because I did not get it to work, I suspect it uses PHP5 and my php version is lower..

The odds are that if veriword.php doesn’t work for you, your custom captcha won’t work either (it works fine in PHP4). I’m going to guess that your problem is that GD and/or Freetype are either not enabled or misconfigured.

The captcha in SPForm is slightly different (though the file is still called veriword.php), you might take a look at it -- you’re welcome to use that code if it works for you.

I’ve have PHP4.. veriword.php prints the following error:
Fatal error: Call to undefined function: imagettfbbox() in /usr/home/abc/domains/abcvathorst.nl/public_html/manager/includes/veriword.php on line 124

So I guessed that imagettfbbox() is a PHP5 function?

With the script what I coded myself I get a captcha picture, but if I post the form the session[’captcha_code’] is not set.
So GD and/or Freetype not seems to be the problem.

Somehow MODX destroys all sessions in $_SESSION if you are not logged into the manager. If I’m logged in the manager my script works.., the captchacode is set in a session.

Still didn’t figure out to solve this problem.
Seems like I can’t use sessions in an external php file in ModX.

Have anyone more info about modx & sessions?
