Hi @oc-wordpress-web-designer

I have tested on a demo installation and it works fine for me.

Do you have the last versión of WordPress and WooCommerce?

Which version of PHP do you have?

It seems that the problem is in the PHP version but check all of this, please.

Regards.

PHP 7.4.4
Wordpress 5.4.1
Woocommerce 4.0.1

Ok, I think that the problem is in the PHP versión.

I have updated to PHP 7.4.1 and it works fine for me.

One moment…..

Revise the ‘ it seems are different. Revise, please…

Here is the code:

// Create and display the custom field in product general setting tab
add_action( ‘woocommerce_product_options_general_product_data’, ‘add_custom_field_general_product_fields’ );
function add_custom_field_general_product_fields(){
global $post;

echo ‘<div class=”product_custom_field”>’;

// Custom Product Checkbox Field
woocommerce_wp_checkbox( array(
‘id’ => ‘_disabled_for_coupons’,
‘label’ => __(‘Disabled for coupons’, ‘woocommerce’),
‘description’ => __(‘Disable this products from coupon discounts’, ‘woocommerce’),
‘desc_tip’ => ‘true’,
) );

echo ‘</div>’;;
}

// Save the custom field and update all excluded product Ids in option WP settings
add_action( 'woocommerce_process_product_meta', 'save_custom_field_general_product_fields', 10, 1 );
function save_custom_field_general_product_fields( $post_id ){

    $current_disabled = isset( $_POST['_disabled_for_coupons'] ) ? 'yes' : 'no';

    $disabled_products = get_option( '_products_disabled_for_coupons' );
    if( empty($disabled_products) ) {
        if( $current_disabled == 'yes' )
            $disabled_products = array( $post_id );
    } else {
        if( $current_disabled == 'yes' ) {
            $disabled_products[] = $post_id;
            $disabled_products = array_unique( $disabled_products );
        } else {
            if ( ( $key = array_search( $post_id, $disabled_products ) ) !== false )
                unset( $disabled_products[$key] );
        }
    }

    update_post_meta( $post_id, '_disabled_for_coupons', $current_disabled );
    update_option( '_products_disabled_for_coupons', $disabled_products );
}

// Make coupons invalid at product level
add_filter('woocommerce_coupon_is_valid_for_product', 'set_coupon_validity_for_excluded_products', 12, 4);
function set_coupon_validity_for_excluded_products($valid, $product, $coupon, $values ){
    if( ! count(get_option( '_products_disabled_for_coupons' )) > 0 ) return $valid;

    $disabled_products = get_option( '_products_disabled_for_coupons' );
    if( in_array( $product->get_id(), $disabled_products ) )
        $valid = false;

    return $valid;
}

// Set the product discount amount to zero
add_filter( 'woocommerce_coupon_get_discount_amount', 'zero_discount_for_excluded_products', 12, 5 );
function zero_discount_for_excluded_products($discount, $discounting_amount, $cart_item, $single, $coupon ){
    if( ! count(get_option( '_products_disabled_for_coupons' )) > 0 ) return $discount;

    $disabled_products = get_option( '_products_disabled_for_coupons' );
    if( in_array( $cart_item['product_id'], $disabled_products ) )
        $discount = 0;

    return $discount;
}

Tell me, please.

I have Theme X (https://themeforest.net/item/x-the-theme/5871901) active and when I deactivated it to a default theme, the issue was removed.

Appears I need to talk to theme support.

Yes but you need to add this code to the default theme functions.php to ensure.

Can you do that?

Oh duh, yes the issue still appears after the code is added to the default theme function.php so its not a theme conflict.

Do you review the ””” and the ′′′′′′ ?

It seems that when you paste the code these ”” are trasnformed to ′′′′′′′

I’m copying to a text editor in plain text and pasting in the function.php in code editor mode. The code is being validated with the correct ‘

I’m sorry but I can’t reproduce your issue.

For me it works fine and I have the last version of WordPress and the last version of WooCommerce.
