I am trying to set a cookie in wordpress that comes from $_GET so I've put this in the bottom of my theme's functions.php:
function set_name_cookie() {
if (isset($_GET['kw'])) {
setcookie('kw',$_GET['kw'], time()+3600*24, '/','.website.com',false);
}
}
add_action( 'init', 'set_name_cookie');
I can see cookies as they're set in Firefox. This cookie is not set when I first load the page, but if I reload the page it is.
Many people have a similar issue where cookie is not set until after the page is loaded so they can't use $_COOKIE['kw'] dynamically in the same page as it's set, but that's not my issue, it's just not setting, when I go to the next page, the $_COOKIE is still empty unless I reload that first page (with the ?kw=XXX in the URL). What could cause that behavior? Is this how it's supposed to work?
EDIT - When I go to mysite.com/test.php?kw=123 which looks like this:
<?
session_start();
if (isset($_GET['kw'])) {
setcookie('kw',$_GET['kw'], time()+3600*24,'/',$_SERVER['HTTP_HOST'],false);
}
?>
<html>
<a href="test2.php">check cookie</a>
</html>
And then click on the link to test2.php, which looks like this:
session_start();
echo 'cookie:'.print_r($_COOKIE);
exit;
I don't see a cookie it's just empty array. If I go back in my browser to test.php and then click through again, I can see it. Am I missing something really obvious?
