如何根据页面重定向用户？

Question

I am trying to use below code that whenever user goes to page name called "Through Phone Call" it should direct him to certain page

In functions.php

function my_custom_add_to_cart_redirect( $url ) {
    $page_title = $post->post_title;
    if ($page_title == "Through Phone Call") {
        $url = get_permalink( 2855 ); 
    } else {
        $url = get_permalink( 1853 ); 
    }
}

But the code is not functioning what i am missing?

According to the docs you need to call wp_redirect() like below:

function my_custom_add_to_cart_redirect( $url ) {
    $page_title = $post->post_title;
    if ($page_title == "Through Phone Call") {
        $url = get_permalink( 2855 ); 
    } else {
        $url = get_permalink( 1853 ); 
    }
    
    wp_redirect( $url );
    exit;
}
