How to create a simple PHP cookie language toggle?

Question

I\'m trying to set up, what I thought would be, a simple language switch. I thought I\'d use PHP cookies, but they\'re not behaving as intended.

I\'ve read a few coo

Thanks for all the suggestions - @Mob set me in the right direction, i.e. processing the cookie on another page and then sending you back to the first.

I did a bit more thinking and experimenting and I've finally solved it. I'll post the code below incase anyone else wants to use this.

On your main page put this:

    
        >English
        >Russian
    
    


Language: not set"; } ?>

Then in another file called 'language_switcher.php' put the following code:

$lang = "en";
if( isset( $_POST["lang"] ) ) {
    $lang = $_POST["lang"];
    setcookie ( 'language', $lang, time() + 60*60*24*30, '/', 'mydomain.com');
    header( "Location: /previous_page_url.php" );
}

The user chooses a language and clicks 'Select Language'. The form then sends the form value to 'language_switcher.php', which sets the cookie and then sends the user back to the previous page.

Done! :)
