Disable add to cart button via custom checkbox in WooCommerce product settings
Explanation via comment tags added in the code
To add a checkbox to the inventory product options, use:
[php]// Add checkbox
function action_woocommerce_product_options_inventory_product_data() {
// Checkbox
woocommerce_wp_checkbox( array(
‘id’ => ‘_prevent_add_to_cart_button’, // Required, it’s the meta_key for storing the value (is checked or not)
‘label’ => __( ‘My label’, ‘woocommerce’ ), // Text in the editor label
‘desc_tip’ => false, // true or false, show description directly or as tooltip
‘description’ => __( ‘Prevent add to cart’, ‘woocommerce’ ) // Provide something useful here
) );
}
add_action( ‘woocommerce_product_options_inventory_product_data’, ‘action_woocommerce_product_options_inventory_product_data’, 10, 0 );
// Save Field
function action_woocommerce_admin_process_product_object( $product ) {
// Isset, yes or no
$checkbox = isset( $_POST[‘_prevent_add_to_cart_button’] ) ? ‘yes’ : ‘no’;
// Update meta
$product->update_meta_data( ‘_prevent_add_to_cart_button’, $checkbox );
}
add_action( ‘woocommerce_admin_process_product_object’, ‘action_woocommerce_admin_process_product_object’, 10, 1 );[/php]
To disable the add to cart button for simple and variable products, use:
[php]// Is_purchasable (simple)
function filter_woocommerce_is_purchasable( $purchasable, $product ) {
// Get meta
$hide_add_to_cart_button = $product->get_meta( ‘_prevent_add_to_cart_button’ );
// Compare
if ( $hide_add_to_cart_button == ‘yes’ ) {
$purchasable = false;
}
return $purchasable;
}
add_filter( ‘woocommerce_is_purchasable’, ‘filter_woocommerce_is_purchasable’, 10, 2 );
// Is_purchasable (variable)
function filter_woocommerce_variation_is_purchasable( $purchasable, $product ) {
$hide_add_to_cart_button = get_post_meta( $product->get_parent_id(), ‘_prevent_add_to_cart_button’, true );
// Compare
if ( $hide_add_to_cart_button == ‘yes’ ) {
$purchasable = false;
}
return $purchasable;
}
add_filter( ‘woocommerce_variation_is_purchasable’, ‘filter_woocommerce_variation_is_purchasable’, 10, 2 );[/php]
Note: There are several ways to disable/remove the add to cart button, so it depends on whether you want to hide or disable the button completely.
