Avoiding error 500 when duplicating hooked functions in Woocommerce

Question

if i use 2 codes in functions.php file. recive error 500 !

use below code for buttom checkout page custom message: Display a custom message for guest users in Woocommerce checkout page

and use below code for top checkout page custom message: Display a custom notice before all default notices in Woocommerce checkout page

if i use together. first (1st link) code for buttom page message and two code (2nd link) for top. cant work together. please help me.

Is there any way we can use two of them for two different messages in the bottom and top? — ahmadwp, Jul 02 '18 at 16:15
Each function need to have a unique name… after all **you can change hooks** to feet your needs (but `wc_add_notice()` is used in `template_redirect` hook and `wc_print_notice()` in the other hooks), *or merge the code in one unique function (as added in my answer)*. — LoicTheAztec, Jul 02 '18 at 16:35

If you want multiple hooked functions (duplicated or not), each of them need a unique unused name:

add_action('template_redirect', 'my_custom_message_one');
function my_custom_message_one() {
    if ( is_checkout() && ! is_wc_endpoint_url() ) {
        wc_add_notice( __('This is my 1st custom message (for all)'), 'notice' );
    }
}

add_action('woocommerce_before_checkout_form', 'my_custom_message_two');
function my_custom_message_two() {
    if ( ! is_user_logged_in() ) {
        wc_print_notice( __('This is my custom message (for non logged users)'), 'notice' );
    }
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

Or you can use one function and 2 notices merged in the same function:

add_action('template_redirect', 'my_custom_message');
function my_custom_message() {
    if ( is_checkout() && ! is_wc_endpoint_url() ) {
        wc_add_notice( __('This is my 1st custom message (for all)'), 'notice' );
    }

    if ( ! is_user_logged_in() && is_checkout() && ! is_wc_endpoint_url() ) {
        wc_add_notice( __('This is my 2nd custom message (for non logged users)'), 'notice' );
    }
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.
