Woocommerce：如何在注销时显示自定义成功通知消息？

Question

On Logout display success message. this is my code that i tried.but i don't get success message on logout

this is my code that i tried.but i don't get success message on logout

function displaynotice() {
    add_action( 'woocommerce_init', 'custom_notice' );
}
add_action('wp_logout', 'displaynotice');

function custom_notice() {
    wc_add_notice( 'This is a Success notice', 'success' );
}

I think when I logout, Wordpress or Woocommerce destroys the current session. So all my flash messages would also get destroyed or unset. So using session would not be an option.

Working solution

in function.php

setcookie('done', null, -1, '/');
add_action('wp_logout',function(){
   setcookie("done", "done", time() + (86400 * 30), "/");
});

and in the page where we want to show the message

<?php 
if(isset($_COOKIE["done"]) && !empty($_COOKIE["done"]) ) {?>
    <div class="woocommerce-message" role="alert">
    You've been logged out successfully.</div>
<?php } ?>

Answer 1

please try using wp_logout action hook, because whenever the user logs out this hook is called and you should add your logout method to this hook.

example :

add_action('wp_logout',function(){
    wc_add_notice( 'This is a Success notice', 'success' );
});
