Problems with $_SESSION

Uwe

Hi Guys,

I am new to this forum and PHP. I have to appoligize for my English and my questions.

I am trying to develop a multi language application where I retrieve the labes from the database. My pages are working fine but the behaviour of PHP is driving me crazy.

<?php
session_start();
login();

// function show_form is working fine

// The problem is that it should show
// Login with Language: ITA, ENG, DEU, FRA but $_SESSION['lang'] is either empty // or a default value

// if I change the language before login on I will have 3 cookies
// Cookie #1 = lang|s:3:"DEU"; This is the default path
// Cookie #2 = lang|s:3:"FRA"; After changing the language
// Cookie #3 = After clicking "Login"
?>

It looks like the programm starts new every time I do anything on the page.

I really hope that somebody can help me.

Cheers
Uwe

You need to check if you have already set your SESSIONS by doing this:

if (isset($_SESSION['lang'])) // Now if this is satisfied, that means a language have been selected.

Unless, you are allowing users to chnage the language at any time of running the application, then you can set other logic where if you detect a new argument, you modify the $_SESSION.

Hope that helps!

Hi dcav,

Thanks for your help.

I did use it, but I took it out. The reason is:

if (! isset($SESSION)) {
$SESSION['lang'] = "ENG";
print "Setting default language";
}

will always happen after each action I do on that page.

That is why I wrote that it looks like the program is starting new. It is setting the default language and the previous action of changing the language is gone.

The second issue with $SESSION is that in a function later in my program (same file) I try to build a
$url = "url?lang=".$SESSION['lang'];
$SESSION['lang'] is empty again.

I have my doubts that the vanilla installation of xampp is working properly but since I do not know how to configure php.ini I can only start fixing the first issue.

Cheers
Uwe

Please post some more code including the html form (maybe as attachment if the code is too large).

Hi Guys,

I found one solution. I wonder if there is a better way. Please let me know if somebody knows a better way:

<?php
session_start();

if (! isset($GET["language"])) {
$SESSION['lang'] = "DEU";
}
else {
$SESSION['lang'] = $GET["language"];
}
