Session Variables and include file

noimad1

Ok,

I am having a problem with a project I am working on.

I have one file that registers my session variables called index.php. Users log in through the index.php page, I pull some data out of a database, like a pathname to a specific directory (different for each user). I then once the user logs in I send them to my admin.php file.

Now here is where the problem is. I also have a button_include.php file that is basically a top bar menu with all the buttons for the site. Now, for the URL of the buttons I uses <a href = $session_path/thisbutton.php>, which is one of my session variables. However, the $ses_path variable keeps being blank here.

It appears that if I include a file, that file does not have access to the session variables? Is that the case, or am I doing something wrong. I can access the variable fine through the admin.php file, just not through the button_include.php file.

Here is some code snipets from the 3 files:

index.php:

<?php
session_start();
session_register('ses_path');
$ses_path = "http://www.whateverstuff.com"

Admin.php

<?php
session_start();
include 'http://mydomain.com/admin/button_include.php';

button_include.php

<?php
session_start();

 echo ("<a href='$ses_path/admin/layout.php' class='headerNavigation'>Site Layout </a>");
?>

You could make your life a little simpler by just registering and setting the value of the $ses_path by doing this

$_SESSION['ses_path']="yourpath.com";

Then when you wan to use that variable you can just call it

i.e.


<?php 
session_start(); 

 echo ("<a href='$_SESSION[ses_path]/admin/layout.php' class='headerNavigation'>Site Layout </a>"); 
?>

Will I be able to call it inside an include file?

I get the following error when I tried it:

Parse error: parse error, expecting T_STRING' orT_VARIABLE' or `T_NUM_STRING' in /home/wedding/public_html/admin/inc_top_buttons.php on line 4

Here is exactly how I did the code:

index.php:

$_SESSION['ses_path'] = mysql_result($result, 0, "path");

Include_buttons:

echo ("<a href='$_SESSION['ses_path']/admin/layout.php' class='headerNavigation'>Site Layout </a>";

Ok,

I figured it out....well actually, I just found another post:

http://www.phpbuilder.com/board/showthread.php?s=&threadid=10255617&highlight=session+variable+include

It turns out, in order to use sesion variables you can not include files using the full pathname as I was....

If your file is getting included it is just like it is part of the same script, so don't stress about that it isn't your problem.

Although are you sure it is getting included? Do you have any error checking? It doesn't look like it from the example you provide below.

Try:

if(!include [url]http://mydomain.com/admin/button_include.php[/url]) {
     die("some error msg");
}

That error is often because there is something going on with the var that PHP doesn't know what to do with.

Few things to try

take out the '' in the href or escape them wiht \'
Try echoing the $_SESSION[ses_path] without putting it the href and see what value it contains.
Post your query, your problem could be in there. Also why use mysql_reuslt, instead of mysql_fetch_... They are faster and you for sure get at least a row. You do have to manipulate it a bit but I find it more reliable.

The file was being included when I was using the

include http://mydomain.com/admin/inc_top_buttons.php';

But the session variable just kept getting lost.

I changed the code to this:

include ('../../admin/inc_top_button.php') and then my session variable was finally able to be extracted. It appears that your session may be destroyed if you include a file using the full domain path.

Basically what that did was go up 2 directory levels, then inside the admin folder. (becuase my admin file was in the mydomain/folder1/folder2 and my include files was in mydomain/admin).

At anyrate, everything is working now, I just wanted to post the answer incase anyone else was having the same problem.
