Avoid repetitive emails notification on some auto completed orders - php

Question

I'm using this little peace of code on WooCommerce from this answer to auto-complete paid processing orders based on payment gateways:
/**
* AUTO COMPLETE PAID ORDERS IN WOOCOMMERCE
*/
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 = wc_get_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 Orders with all others payment methods
else {
$order->update_status( 'completed' );
}
}
This is working mostly perfect
Mainly using a special payment gateway by SMS which API is bridged on 'cod' payment method and that can process payment after 'woocommerce_thankyou, out side frontend. In that case the ON HOLD status orders are passed afterward to PROCESSING status. To automate an autocomplete behavior on those cases, I use this other peace of code from this answer and it works:
function auto_update_orders_status_from_processing_to_completed(){
// Get all current "processing" customer orders
$processing_orders = wc_get_orders( $args = array(
'numberposts' => -1,
'post_status' => 'wc-processing',
) );
if(!empty($processing_orders))
foreach($processing_orders as $order)
$order->update_status( 'completed' );
}
add_action( 'init', 'auto_update_orders_status_from_processing_to_completed' );
THE PROBLEM: I am getting repetitive emails notifications concerning the new completed orders.
How can I avoid this repetitive email notifications cases?
Thanks

Updated (2019)
Added version code for Woocommerce 3+ - Added Woocommerce version compatibility.
To avoid this strange fact of repetitive email notifications, is possible to create a custom meta key/value for each processed order, when changing order status to completed, using WordPress update_post_meta() function. Then we will test before in a condition, if this custom meta data key/value exist with get_post_meta() function for each processed order.
So your two code snippets will be now:
1) AUTO COMPLETE PAID ORDERS IN WOOCOMMERCE (2019 update)
For woocommerce 3+:
add_action( 'woocommerce_payment_complete_order_status', 'wc_auto_complete_paid_order', 10, 3 );
function wc_auto_complete_paid_order( $status, $order_id, $order ) {
if ( ! $order->has_status('completed') && $order->get_meta('_order_processed') != 'yes') {
$order->update_meta_data('_order_processed', 'yes');
$status = 'completed';
}
return $status;
}
For all woocommerce versions (compatibility since version 2.5+):
add_action( 'woocommerce_payment_complete_order_status', 'wc_auto_complete_paid_order', 10, 3 );
function wc_auto_complete_paid_order( $status, $order_id, $order = null ) {
// Getting the custom meta value regarding this autocomplete status process
$order_processed = get_post_meta( $order_id, '_order_processed', true );
// Getting the WC_Order object from the order ID
$order = wc_get_order( $order_id );
if ( ! $order->has_status( 'completed' ) && $order_processed != 'yes' ) {
$order = wc_get_order( $order_id );
// setting the custom meta data value to yes (order updated)
update_post_meta($order_id, '_order_processed', 'yes');
$order->update_status( 'completed' ); // Update order status to
}
return $status;
}
2) SCAN ALL "processing" orders to auto-complete them (added Woocommerce compatibility)
add_action( 'init', 'auto_update_orders_status_from_processing_to_completed' );
function auto_update_orders_status_from_processing_to_completed(){
if( version_compare( WC_VERSION, '3.0', '<' ) {
$args = array('numberposts' => -1, 'post_status' => 'wc-processing'); // Before WooCommerce version 3
} else {
$args = array('limit' => -1, 'status' => 'processing'); // For WooCommerce 3 and above
}
// Get all current "processing" customer orders
$processing_orders = (array) wc_get_orders( $args );
if( sizeof($processing_orders) > 0 ){
foreach($processing_orders as $order ) {
// Woocommerce compatibility
$order_id = method_exists( $order, 'get_id' ) ? $order->get_id() : $order->id;
// Checking if this custom field value is set in the order meta data
$order_processed = get_post_meta( $order_id, '_order_processed', true );
if (! $order->has_status( 'completed' ) && $order_processed != 'yes' ) {
// Setting (updating) custom meta value in the order metadata to avoid repetitions
update_post_meta( $order_id, '_order_processed', 'yes' );
$order->update_status( 'completed' ); // Updating order status
}
}
}
}
Code goes in function.php file of your active child theme (or theme). Or also in any plugin php files.
I have test this code and it should work for you (due to your particular SMS bridged payment method)
