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

Answer 1

A cookie is not accessible until the setting page has been reloaded or another page has been accessed (in other words, you cannot set and access a cookie in the same page).

Check this code out :

if( $_GET['lang'] ) {
    $lang = (string)$_GET['lang'];
    setcookie( 'lang', $lang, time() + 60*60*24*30,'/' );
} elseif(  !$_GET['lang']) ) {
    $lang = 'en';
} else {
    $lang = $_GET['lang'];
}
header("Location: redirect_file.php")

Then in redirect_file.php, you redirect back to the cookie page. Perform some checks if you want to avoid redirect loops.
