Working with sessions

Hello, there.

I've been reading faq434-2036 about Session Handling but still can work this issue out...

I am converting a static site into a dynamic one. One of the features involves i18n.
Example: I have a link on every PHP page which allows the user to switch languages in this way:

Code: 
<a href="<?=$_SERVER['PHP_SELF']?>?lang=es">espa&ntilde;ol</a>
Code: 
<a href="<?=$_SERVER['PHP_SELF']?>?lang=en">english</a>

In this way, I am using GET to send the [tt]lang[/tt] variable to the page itself when reloading.

On top of every site's page I include the following

Code: 
<?
  require_once "inc/sess.php";
?>

...where I handle the session in the following way:

Code: 
<?
///  sess.php

session_start();
$lang = $_GET['lang'];
if(!isset($_SESSION['language']) ||
   $lang!=$_SESSION['language']) {
   if( isset($lang) ) {
      $_SESSION['language'] = $lang;
   } else {
      $_SESSION['language'] = 'es';	
   }
}
?>

Doing this, I set Spanish as the default language or set the session variable to the language specified in the [tt]lang[/tt] variable.

I require the same code snippet on every page but when navigate to other page, the language is not set and drops to the default: Spanish....

I assume it's my logic proble, 'cause I've read PHP documentation about Sessions and it's very simple [sad]
and it makes me feel still more stupid [rednose]

Thanks In Advance

You've shown the code which stores the value in a session variable. How are you using that value in that session variable in your code?

sleipnir214,

Thanks for replying.

In fact the code I use on every page is the same I posted.

I am sorry, I don't understando what do you need... :-(

The code you've posted stores the value in a session variable. The problem you describe could be caused by your application improperly storing the value, or by improperly trying to use that value later on.

Just storing the value in a session is not enough. In successive scripts, you need to use that value. How are you doing that?

Oh, I understand now :)

This way:

Code: 
require_once "inc/i18n/".$_SESSION['language'].".php";

Yes, of course.

It loads [tt]inc/i18n/es.php[/tt] for Spanish and [tt]inc/i18n/en.php[/tt] for English

When I navigate to another page...
The session value does not exist anymore...

session_start() must be invoked in every script which will manipulate session data. Are these other scripts invoking session_start()?

Let's simplify the problem.

Here's two scripts:

session_set.php:
Code: 
<?php
session_start();

$_SESSION['foo'] = 1;

print '<html><body><a href="session_read.php">click here</a></body></html>';
?>[code]

[b]session_read.php[/b]:
[code]<?php
session_start();

print '<html><body><pre>';

print_r ($_SESSION);

print '</pre></body></html>';
?>

If you create the two scripts, point your web browser to set_session.php, then click on the link, what you do get?

As expected, I get the following....

[tt]
Array
(
[foo] => 1
)
[/tt]


Anyway, I don't understand why my [tt]$_SESSION['language'][/tt] variable value is not alive when I navigate...

Perhaps my logic is bad...

The I don't know what is causing the problem.

I recommend that you footprint your code to see what exactly is going on. Judicious use of error_log() to track what's going on in your code might be helpful.

Thank you very much. I'll investigate this.

Do you have a paranoid firewall?

Try this code:
Code: 
echo "<a href=\"{$_SERVER['PHP_SELF']}?=<?=SID?>&amp;lang=es\" title=\"espa&ntilde;ol, sen&ntilde;rita\">espa&ntilde;ol</a>";

if it works, also put the SID in your form actions..

If it works, your problem was doe to your firewall blocking the session cookie.
