How to Implement

  1. Create a code snippet in one of these places:
    • WordPress Admin > Snippets (if using Code Snippets plugin)
    • wp-content/mu-plugins/probo-customizations.php (MU-plugin)
    • Child theme's functions.php
    • Your own plug-in

  1. Use this template:

    add_filter( 'hook_name', function ( $param1, $param2 ) {
    // Customize here
    return $param1;
}, 10, 2 );

  2. Test in a staging environment first!

Quick Examples

Hide weekends from delivery dates:

add_filter( 'probo_shipping_delivery_dates', function ( $dates ) {
    return array_filter( $dates, function ( $date ) {
        $day = date( 'N', strtotime( $date['date'] ) );
        return $day < 6; // Mon-Fri only
    });
}, 10, 1 );

Add 20% markup to rush surcharges:

add_filter( 'probo_shipping_overwrite_rush_surcharge', function ( $surcharge, $delivery, $price ) {
    return $surcharge  1.2;
}, 10, 3 );

Send notification when order is completed:*

add_action( 'probo_order_status_change_completed', function ( $order_id, $status ) {
    wp_mail( 
        'manager@store.com', 
        "Order #{$order_id} Completed", 
        "Order is ready to fulfill!"
    );
}, 10, 2 );

Prevent auto-order for large quantities:

add_filter( 'probo_order_may_auto_order_direct_file', function ( $can_auto, $item ) {
    if ( $item->get_quantity() > 100 ) {
        return false; // Require manual review
    }
    return $can_auto;
}, 10, 2 );

Code snippets not working?

If your snippet "does nothing", it's almost always one of three things: (1) the hook name is misspelled, (2) the priority/argument count is wrong, or (3) your code loads too late. Check your site's error log for PHP syntax errors.
