Set WooCommerce order status when order is created from processing to pending

Question

When a woocommerce order is created the status of the order is "processing". I need to change the default order-status to "pending".

How can I achieve this?

Answer 1

The default order status is set by the payment method or the payment gateway.

You could try to use this custom hooked function, but it will not work (as this hook is fired before payment methods and payment gateways):

add_action( 'woocommerce_checkout_order_processed', 'changing_order_status_before_payment', 10, 3 );
function changing_order_status_before_payment( $order_id, $posted_data, $order ){
    $order->update_status( 'pending' );
}

Apparently each payment method (and payment gateways) are setting the order status (depending on the transaction response for payment gateways)…

For Cash on delivery payment method, this can be tweaked using a dedicated filter hook, see:
Change Cash on delivery default order status to "On Hold" instead of "Processing" in Woocommerce

Now instead you can update the order status using woocommerce_thankyou hook:

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

    $order = wc_get_order( $order_id );

    if( $order->get_status() == 'processing' )
        $order->update_status( 'pending' );
}

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

Tested and works

Note: The hook woocommerce_thankyou is fired each time the order received page is loaded and need to be used with care for that reason...
Now the function above will update the order status only the first time. If customer reload the page, the condition in the IF statement will not match anymore and nothing else will happen.

Answer 2

Nowadays, if the payment gateway that you use properly sets the order status using WC_Order->payment_complete(), you can use the woocommerce_payment_complete_order_status filter.

This is better than using woocommerce_thankyou hook since we are setting the order status immediately, rather than applying it after it has been already set.

function h9dx3_override_order_status($status, $order_id, $order) {
  if ($status === 'processing') {
    $status = 'pending';
  }

  return $status;
}
add_filter('woocommerce_payment_complete_order_status', 'h9dx3_override_order_status', 10, 3);

Again, this will only work if the payment gateway uses the proper payment_complete wrapper method rather than setting status directly with set_status. You can just search the gateway code for 'payment_complete(' and 'set_status(' to see what it does.

If you develop a plugin for everyone, you will be better off with using woocommerce_thankyou, or you could use a combined approach and use woocommerce_thankyou as the fallback if the order status was not updated.
