Change order status just after payment in WooCommerce [duplicate] - php

WooCommerce: Auto complete paid orders
(5 answers)
Closed 3 years ago.
I need to change automatically an order status for completed after receiving payment, but only if the order status is "processing". I found that snippet, what makes orders status completed in every case, but my payments plugins after successful payment changes returns data and changes the order status for "processing". I would like to change it into "completed" after success and don't change it if the status isn't "processing". The main problem I met is I don't know how to get the received status order.
Here is my code:
add_filter( 'woocommerce_thankyou', 'update_order_status', 10, 2 );
function update_order_status( $order_id ) {
$order = new WC_Order( $order_id );
$order_status = $order->get_status();
if ('processing' == $order_status) {
$order->update_status( 'completed' );
}
//return $order_status;
}
Edit:
I figured it out already. Here's the code that works for me:
add_filter( 'woocommerce_thankyou', 'update_order_status', 10, 1 );
function update_order_status( $order_id ) {
if ( !$order_id ){
return;
}
$order = new WC_Order( $order_id );
if ( 'processing' == $order->status) {
$order->update_status( 'completed' );
}
return;
}

Update 2 - 2019: Use WooCommerce: Auto complete paid orders (updated thread)
So the right hook to use is woocommerce_payment_complete_order_status filter returning complete
Update 1: Compatibility with WooCommerce version 3+
I have changed the answer
Based on: WooCommerce - Auto Complete paid virtual Orders (depending on Payment methods), you will be able to handle also all payment methods in conditionals:
// => not a filter (an action hook)
add_action( 'woocommerce_thankyou', 'custom_woocommerce_auto_complete_paid_order', 10, 1 );
function custom_woocommerce_auto_complete_paid_order( $order_id ) {
if ( ! $order_id )
return;
$order = new WC_Order( $order_id );
// No updated status for orders delivered with Bank wire, Cash on delivery and Cheque payment methods.
if ( get_post_meta($order_id, '_payment_method', true) == 'bacs' || get_post_meta($order_id, '_payment_method', true) == 'cod' || get_post_meta($order_id, '_payment_method', true) == 'cheque' ) {
return;
}
// "completed" updated status for paid "processing" Orders (with all others payment methods)
elseif ( $order->has_status( 'processing' ) ) {
$order->update_status( 'completed' );
}
else {
return;
}
}

The function woocommerce_thankyou is an action. You're required to use add_action function to hook into it. I would recommend changing the priority to 20 so that other plugins/code changes may be applied before update_order_status.
add_action( 'woocommerce_thankyou', 'update_order_status', 20);
