PHP setcookie() function not working in Wordpress Template File

Question

I am using this code to set a cookie in a wordpress site. When I place this code in header.php, it works perfectly. But when I place this code in Separate template file, it does not work. Header File Code: (Before HTML Tag)

if (isset($_COOKIE['City'])) {
setcookie('City', 0, -(3600*3600*3600));
setcookie('City', "Edmonton2", 3600*3600*3600);
}
else {
setcookie('City', "Edmonton", 3600*3600*3600);
}

WP Template File Code: (Code is before the get_header() function)

<?php 
if (isset($_COOKIE['City'])) {
setcookie('City', 0, -(3600*3600*3600));
setcookie('City', "Edmonton2", 3600*3600*3600);
}
else {
setcookie('City', "Edmonton", 3600*3600*3600);
}
?>
<?php
/*
    Template Name: Community Landing Page
*/
get_header(); ?>

Any help would be highly appreciated. Thanks & Regards

Answer 1

The problem was I did not mention the path in the function. The code was creating cookie for the particular page. Here is the corrected function:

setcookie('City', "Edmonton43003", (time()+3600), "/");
