Change Woocommerce Order Status based on Shipping Method

Question

The idea here is that when an order comes in with an \"express delivery\" as Shipping Method, the order status is updated to On-Hold.

As there I have some different

Answer 1

I prefer to use the faster and less memory intensive function strpos() instead as the shipping method ID is alway in lowercase (like a kind of slug).

So is better the get the WC_Order_Item_Shipping object data for this case, using the available methods.

So the code should be:

add_action( 'woocommerce_thankyou', 'express_shipping_update_order_status', 10, 1 );
function express_shipping_update_order_status( $order_id ) {
    if ( ! $order_id ) return;
    
    $search = 'express'; // The needle to search in the shipping method ID

    // Get an instance of the WC_Order object
    $order = wc_get_order( $order_id );

    // Get the WC_Order_Item_Shipping object data
    foreach($order->get_shipping_methods() as $shipping_item ){
        // When "express delivery" method is used, we change the order to "on-hold" status
        if( strpos( $shipping_item->get_method_title(), $search ) !== false && ! $order->has_status('on-hold')){
            $order->update_status('on-hold');
            break;
        }
    }
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

Tested and works…

Answer 2

So the code above didn't work for me, i had someone in a FB group help me debug it and this was the final one that worked for me

add_action( 'woocommerce_thankyou', 'express_shipping_update_order_status', 10, 1 );
function express_shipping_update_order_status( $order_id ) {
    if ( ! $order_id ) return;

    $search = 'express'; // The needle to search in the shipping method ID

    // Get an instance of the WC_Order object
    $order = wc_get_order( $order_id );

    // Get the WC_Order_Item_Shipping object data
    foreach($order->get_shipping_methods() as $shipping_item ){
        // When "express delivery" method is used, we change the order to "on-hold" status
        if( strpos( $shipping_item->get_method_title(). $search ) !== false ){
            $order->update_status('on-hold');
            $order->save();
            break;
        }
    }
}
