Using PHP hooks

What hooks are​

Fluid Checkout PRO runs WordPress actions and filters for the cart, order pay, order received, and the features that ship with PRO. They work alongside Fluid Checkout Lite hooks, so a store running both plugins can use either set.

Address Book hooks use the prefix fc_adb_. Google Address Autocomplete hooks use the prefix fc_gaa_. You do not need to edit the plugin.

Actions and filters​

An action runs your code at a moment in the page. fc_pro_order_received_successful runs on the order received page after a successful order.

A filter receives the current value and must return a replacement. fc_pro_cart_action_label_continue_shopping receives the Continue shopping label on the cart.

The actions and filters lists below include every hook exported from Fluid Checkout PRO.

Read a hook page​

Open a hook for its type, the signature, the parameters table, the version that introduced it, and the PHP file that runs it. When you accept more than one parameter, set that count on add_action or add_filter. The example below accepts the order object passed to the order received action.

Example​

/**
 * Change the Continue shopping label on the cart.
 *
 * @param string $value Label text.
 * @return string
 */
add_filter( 'fc_pro_cart_action_label_continue_shopping', function( $value ) {
    return __( 'Back to the shop', 'my-store' );
}, 10 );

/**
 * Thank the customer on the order received page.
 *
 * @param \WC_Order $order Order object.
 */
add_action( 'fc_pro_order_received_successful', function( $order ) {
    echo '<p>' . esc_html( sprintf(
        /* translators: %s: customer first name */
        __( 'Thanks for your order, %s.', 'my-store' ),
        $order->get_billing_first_name()
    ) ) . '</p>';
}, 10 );
