Settings go blank...

Whenever I change a setting in the admin panel, it updates, but not properly. For example, I tried to set CSS buttons value to true instead of false, and when I edited it, and then submitted the new value, the value went completely blank instead of being ture, so, i tried to switch it back to false, and the same thing happened. I decided to remove the ez-pages from the public view, but, then decided i wanted them back, and it is just blank, and i cant get it to change. i could however do this all manually through phpmyadmin, but, the guy that is going to be running the site doesnt know how to do any of that, so, this really needs to be working properly, especially when he goes to add his CC info for his merchant account and stuff like that. please help. thanks in advance.

sorry for the double post, but, the system would not let me edit my message

i am not sure if this is gong to make a difference or not, but, here is my php and mysql version

PHP - version 4.4.4
MySQL - version 4.1.21-standard

sorry for the bump, but, i really need to get this problem solved. does anyone have any solution. i tried the ask a question button on the zencart site, and i still havent heard form anyone, and not sure if they even recieved the email since there was no conformation email. someone please help.

The forum is the place to ask for support. Posting here is appropriate.

Did you install manually or via an automated install such as Fantastico ?
Who is your hosting company ?

Additional details:
I am a programmer, and I have discovered that when settings are changed in the admin page, they do NOT show up in $_POST...$_POST exists, but is empty. As such, blank data is put in the database. Apache version 1.3.37, PHP 5.2.3. As such, the shopping cart is also always empty.

At what stage is the $_POST found to be empty?
Is $_GET also empty ? (assuming you're on a page where $_GET is relevant)
Does this happen to you if you do a similar installation on a live commercially-operated server, instead of self-hosted?
Does this happen to you on a different version of PHP ?
What are your PHP settings related to GPC ?
Do you have a relationship to the original poster, or is your comment another instance of similar problem?

You claim to have some knowledge of debugging, so here are some more questions:
At what stage is the $_POST found to be empty? anytime after the form is submitted...in other words, it never gets filled at all

Is $_GET also empty ? (assuming you're on a page where $_GET is relevant) no - its the admin config page with zone, store name, etc...the edit/save var still works fine, so $_GET is fine

Does this happen to you if you do a similar installation on a live commercially-operated server, instead of self-hosted? don't have one with the same setup to test

Does this happen to you on a different version of PHP? can't really test it

What are your PHP settings related to GPC ? variables_order GPCS GPCS

Do you have a relationship to the original poster, or is your comment another instance of similar problem? another instance...saw the thread, having the same problem...jumped at the opportunity :P

On a side note, OSCommerce has the same problem.

it is the newest version of zencart, not any upgrade version, it was the full version.
the are no addons or modifications as of yet.
i was testing in IE, and haven't moved to firefox yet, and i highly doubt it is a browser issue since it is updating the table, just not properly.
it was a manual install, and i have installed it on 3 other sites prior to this, but, it was an older version.
there were no warning on the systems inspection page.
these issues are new hence the site being new.

the site it occurs on is http://www.carterellis.com/index.php

i am thinking that the problem could be because an older version may not have used $_POST, and then may have been carried over to this version. the reason i say this is because i have seen this problem before when code was missing $_POST, so, data would be inserted blank.
i haven't done any front end testing just yet since i was working on the admin panel first, but, the site is currently set with the test items that come with zencart. please let me know if you have seen this issue in zencart before, and what i may do to fix it. i code php too, but, i really don't want to go poking through the code that much and risk messing something up since some of it is a bit above my level of expertise.

If Zen Cart is to blame, then I'd be expecting that $_POST would have data immediately after form submission but then lost it during some sort of sanitization. I can't say that I've ever seen that happen though.

But if $_POST is never getting set as you say, then you have a problem with your server configuration. Perhaps mod_security set too tight? or something else blocking $_POST data from getting through to PHP scripts.

I know for a fact it's not all $_POST data. I tested it with a little home-made script, and $_POST data came through perfectly fine, just like I expected.

Are there any errors in the server errorlog related to your admin pages ?

Nope, error logs are clean for apache, php, and mysql.

i use $_POST, $_GET, and $_REQUEST on plenty of other things i have coded and i dont have any problems, so, i know it is not a server issue. and as i said befoer, i have had zencart before, but, it was an older version, and an older server. but, i did however have it on this server too before, on an older site, and it seemed fine, so, i am not sure why this is happening now.

same here

Oh, just to make sure that $_POST is never set, here's the test code I used admin/configuration.php:

require('includes/application_top.php');

$action = (isset($_GET['action']) ? $_GET['action'] : '');

if (zen_not_null($action)) {
switch ($action) {
case 'save':
// demo active test
echo "VALUE: '".$_POST['configuration_value']."'"; //TEST CODE

Let's do some debugging then.

You said this was related to the Admin "configuration" screen, so edit the /admin/configuration.php file
Around line 24 you'll see this:require('includes/application_top.php');put this on the line ABOVE that:```
echo '<pre>' . print_r($_POST, true) . '</pre>';

What do you see ? (besides a bunch of "Cannot send session headers -- headers already sent" messages and maybe a javascript error or two)

i have the same exact version of zencart on another site just so you can see that it is working

http://www.methodcomptech.com/zencart/

same version, and did the same install, and same server. please explain to me why that one works, but, the other one doesnt. :S
