Why I get no session id?

[RyuMaster]

Hi! I have some custom code snippet. Based on GET data, it fills cart with products, and redirects to shopping cart. Also it sets custom session variable on the way. The problem is... it works only once!! If I close browser, use same link again, I get "shopping cart is empty", like no session ID data is passed anymore. WHY???

 

http://www.balblabla.com/checkout_sample.php?tempData=9884959&name0=Base0

 

 

 

require('includes/application_top.php');

 

 

$first = 0;

$ses = "";

$q = explode("&",$_SERVER["QUERY_STRING"]);

 

foreach ($q as $qi)

{

if ($qi != "")

{

$qa = explode("=",$qi);

list ($key, $val) = $qa;

if ($val){

if($first != 0)

{

$products_query = tep_db_query("SELECT * FROM " . TABLE_PRODUCTS_DESCRIPTION . " WHERE products_name = \"".$val ."\"");

$products = tep_db_fetch_array($products_query);

 

$products_query2 = tep_db_query("SELECT * FROM " . TABLE_PRODUCTS_ATTRIBUTES . " WHERE options_id = \"6\" AND products_id = \"".$products["products_id"] ."\"");

$attributes_mysql = tep_db_fetch_array($products_query2);

 

$attributes = array(6 => $attributes_mysql["options_values_id"]);

$cart->add_cart($products["products_id"],1,$attributes);

echo "add";

 

}

else

{

 

echo "id?". tep_session_id();

 

$cart->remove_all();

 

tep_session_register('id_string');

$_SESSION['id_string']= $val;

$first = 1;

 

 

}

 

}

}

}

 

tep_redirect(tep_href_link(FILENAME_SHOPPING_CART, '', 'NONSSL', true))

 

And I can see that tep_session_id() always returns correct session variable. Argh!!! Also, backend settings are:

 

 

Force Cookie Use False

Check SSL Session ID False

Check User Agent False

Check IP Address False

Prevent Spider Sessions True

Recreate Session True

Also if it helps to understand the problem:

On the first, correct time, link looks like this:

http://xxxx/shopping_cart.php?osCsid=6667pga27390svq2fmgmhlg985'>http://xxxx/shopping_cart.php?osCsid=6667pga27390svq2fmgmhlg985

and then:

http://xxxx/shopping_cart.php

 

So I see that osCsid gets lost, but dunno why

In a standard install of oscommerce the oscid is removed from the url after a few clicks, but the session should still keep things like cart contents in the cart.

[RyuMaster]

I have standart install, no custom modifications or anything. Except this php script is my own. So you say this behavior is predictable. hmmm. I thought cart contents are getting removed because oscid is removed, but then maybe I have to look somewhere else for the solution, around the cart empty function I use or something. Still, I checked the order with echo, it always the same. Firstly, function removes cart contents. Then adds products. HMM

 

 

I did more tests, actually removing those lines completely

 

$cart->remove_all();

 

tep_session_register('id_string');

$_SESSION['id_string']= $val;

still yields same result. So I don't know where to start now.

[RyuMaster]

Actually I did more tests. It always starts working if I close browser/open it again. Else not matter what I do - completely delete cookies, history erase - no good, works just for a first time. Deleting sessions from database not helping too.

So if taht is not sessions and cookies, then what? 0_0 headers?

Disable your custom code, check the cart again, if the cart contents stay in the cart, you know your code is incorrect.
