Change order status for backordered items in Woocommerce

I am configuring a webshop using WordPress and WooCommerce. I have a plugin installed called Woo Multi Order Creator. What is does is that whenever an order of more than 1 item is made, it divides the main order into multiple orders, one order per purchased item.

Now, what I want to do is to make it change the order status of each order, if the item in each order is containing meta key with the value “Backordered”.

For example if product A and product B are purchased. Product A is in backorder, and therefore has {$wpdb->prefix}woocommerce_order_itemmeta.meta_key = 'Backordered' and product B would be in stock, and it would not have the metakey for backorder.

Now, the thing is that the plugin divides this order into two orders, one per purchased item. What I want it to do further, is to see if the items containted in each new order has the metakey for backorder, and if it has then change the order status to ‘waiting’, for every order.

Plugin code:

    }
}

function my_sortable_cake_column( $columns ) {
$columns['delivery'] = 'delivery';
    return $columns;
}

It changes the order status to processing at line 253.

I’m guessing that it is around here that a bit of code should be added to make it change order status to waiting instead, if the item in the order has the metakey for backorder.

I hope that someone with more expertise than my very limited knowlegde can come to my assistance.

Answer

Here is a hooked function that is triggered when orders get a “processing” status.

Inside the function we look for order items that are “Backordered” with a simple and light SQL query from the order ID.

If a “Backordered” item is found, we change the order status to “on-hold” (the correct order status for your case).

The code:

add_action('woocommerce_order_status_processing', 'pending_back_orders_to_on_hold', 60, 2 );
function pending_back_orders_to_on_hold( $order_id, $order ) {
    global $wpdb;

    // The SQL query for Order items in backorder
    $results = $wpdb->get_col( "
        SELECT woim.meta_value FROM {$wpdb->prefix}woocommerce_order_itemmeta as woim
        INNER JOIN {$wpdb->prefix}woocommerce_order_items as woi ON woim.order_item_id = woi.order_item_id
        WHERE woi.order_id = '$order_id' AND woim.meta_key = 'Backordered'
    " );
    
    // If an item is 'Backordered' we change the order status to "on-hold"
    if(reset($results) > 0)
        $order->update_status('on-hold');
}

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

Tested and works.

Update (related to your comment)

If you want to change the code inside the plugin for that purpose, you will replace line 253:

$order->update_status('processing');

By the following code:

$line_item_ids = array_keys( $order->get_items() );
$backordered = wc_get_order_item_meta( reset($line_item_ids), 'Backordered', true );
$changed_status = $backorders > 0 ? 'on-hold' : 'processing';
$order->update_status( $changed_status );

It should work, but this is not a good practice.
