How to Password Protect Add to Cart button in WooCommerce

Requirements:

• Password Protect WordPress Lite version 1.2.3 or greater
• Password Protect WordPress Pro version 1.1.6 or greater

Once a WooCommerce product page is password protected with our PPWP Pro plugin, the whole page will be hidden under a password form by default.

If you want to hide the Add to Cart button only, simply add the following code snippet to your (child) theme’s functions.php file.

/*
 *
 * Hide Add to Cart on all password protected pages.
 */

function ppwp_replace_add_to_card()
{
    echo get_the_password_form();
}

add_filter(
    'post_password_required',
    function ( $required, $post ) {
        global $post;
        if ( ! $post->ID ) {
            return $required;
        }
 
        if ( ! function_exists( 'is_product' ) ) {
            return $required;
        }
 
        if ( $required && is_product() ) {
            add_filter( 'woocommerce_is_purchasable', '__return_false' );
            add_action( 'woocommerce_simple_add_to_cart', 'ppwp_replace_add_to_card' );
            add_action( 'woocommerce_grouped_add_to_cart', 'ppwp_replace_add_to_card' );
            add_action( 'woocommerce_variable_add_to_cart', 'ppwp_replace_add_to_card' );
            add_filter(
                'woocommerce_available_variation',
                function () {
                    return [];
                }
            );
            add_filter(
                'woocommerce_out_of_stock_message',
                function () {
                    return '';
                }
            );
 
            return false;
        }
 
        return $required;
    },
    200,
    2
);

Your WooCommerce product page will display as below:

Hide Add to Cart button on certain pages only

Use the following code snippet if you want to hide this button on specific password protected WooCommerce product pages only.

/*
 *
 * Hide Add to Cart on certain pages only, e.g. post_id=44 & 45
 */

function ppwp_replace_add_to_card()
{
   echo get_the_password_form();
}
add_filter(
   'post_password_required',
   function ($required, $post) {
       global $post;
       if (!$post->ID) {
           return $required;
       }
 
       if (!function_exists('is_product')) {
           return $required;
       }
 
       $posts_included = [44,45]; // replace the IDs accordingly
       if (!in_array($post->ID, $posts_included)) {
           return $required;
       }
 
       if ( $required && is_product() ) {
            add_filter( 'woocommerce_is_purchasable', '__return_false' );
            add_action( 'woocommerce_simple_add_to_cart', 'ppwp_replace_add_to_card' );
            add_action( 'woocommerce_grouped_add_to_cart', 'ppwp_replace_add_to_card' );
            add_action( 'woocommerce_variable_add_to_cart', 'ppwp_replace_add_to_card' );
            add_filter(
                'woocommerce_available_variation',
                function () {
                    return [];
                }
            );
            add_filter(
                'woocommerce_out_of_stock_message',
                function () {
                    return '';
                }
            );
 
            return false;
        }
 
        return $required;
   },
   200,
   2
);
