WooCommerce: Change order status based on custom Meta Value - php

Question

I'm trying to run the following function daily, to auto-complete all processing order older than 10 days and who have a specific custom meta value.
I'm using the following snippet, however this will simply not work. Any idea as to why?
function autoComplete(){
$orders = wc_get_orders( array(
'status' => 'wc-processing',
'date_created' => '<' . ( time() - 10 * DAY_IN_SECONDS ),
'meta_key' => 'status_us',
'meta_compare' => '=',
'meta_value' => 'Sent to USA',
) );
foreach ($orders as $order){
$order->update_status( 'completed' );
}
}
if ( ! wp_next_scheduled( 'autoComplete' ) ) {
wp_schedule_event( time(), 'daily', 'autoComplete' );
}
Is there any error I've missed? Thanks for your help!

Answer 1

You did a good attempt but you made a few mistakes.
The following code goes inside your functions.php.
add_action( 'wp_loaded','start_custom_code' );
// Once everything theme and plugins are loaded we register our cron job.
function start_custom_code() {
if ( ! wp_next_scheduled( 'bks_mark_processing_order_complete_if_sent_to_usa' ) ) {
wp_schedule_event( time(), 'daily', 'bks_mark_processing_order_complete_if_sent_to_usa' );
}
}
add_action( 'bks_mark_processing_order_complete_if_sent_to_usa', 'bks_mark_processing_order_complete_if_sent_to_usa' );
Your function has minor errors bks_mark_processing_order_complete_if_sent_to_usa()
function bks_mark_processing_order_complete_if_sent_to_usa(){
$args = array(
'status' => array( 'wc-processing'),
'limit' => -1,
'date_created' => '>' . ( time() - 864000 ), // your mistake 1
'status_us' => 'Sent to USA', // your mistake 2
);
$orders = wc_get_orders( $args );
foreach ($orders as $order){
$order->update_status( 'completed' );
$order->save(); // your mistake 3
}
};
Mistake Explanations
While your attempt was in right direction but 'date_created' => '<' . ( time() - 10 * DAY_IN_SECONDS ), you had to use > instead of < also you didn't acutally set DAY_IN_SECONDS You had to replace it with 86400. So the correct value would be '>' . ( time() - 864000 ). For 10 days 10 * 86400 = 864000. You can read about this explanation here in the WooCommerce documentation.
Here I have created new custom variable for you which is set using woocommerce_order_data_store_cpt_get_orders_query and then queried. Code that needs to be added.
function handle_custom_query_var( $query, $query_vars ) {
if ( ! empty( $query_vars['status_us'] ) ) {
$query['meta_query'][] = array(
'key' => 'status_us',
'value' => esc_attr( $query_vars['status_us'] ),
);
}
return $query;
}
add_filter( 'woocommerce_order_data_store_cpt_get_orders_query', 'handle_custom_query_var', 10, 2 );
You updated the status but you forgot to save it. $order->save();
So to summarise you have to add the following code in your functions.php
add_action( 'wp_loaded','start_custom_code' );
add_action( 'bks_mark_processing_order_complete_if_sent_to_usa', 'bks_mark_processing_order_complete_if_sent_to_usa' );
function start_custom_code() {
if ( ! wp_next_scheduled( 'bks_mark_processing_order_complete_if_sent_to_usa' ) ) {
wp_schedule_event( time(), 'daily', 'bks_mark_processing_order_complete_if_sent_to_usa' );
}
}
function bks_mark_processing_order_complete_if_sent_to_usa(){
$args = array(
'status' => array( 'wc-processing'),
'limit' => -1,
'date_created' => '>' . ( time() - 864000 ),
'status_us' => 'Sent to USA',
);
$orders = wc_get_orders( $args );
foreach ($orders as $order){
$order->update_status( 'completed' );
$order->save();
}
};
function handle_custom_query_var( $query, $query_vars ) {
if ( ! empty( $query_vars['status_us'] ) ) {
$query['meta_query'][] = array(
'key' => 'status_us',
'value' => esc_attr( $query_vars['status_us'] ),
);
}
return $query;
}
add_filter( 'woocommerce_order_data_store_cpt_get_orders_query', 'handle_custom_query_var', 10, 2 );
The above code is TESTED and WORKS.
Proof:
Install WP CRON plugin to check your cron. See above screenshot. You can test by hitting Run Now.
Caveat :
WP Cron runs, when somebody visits your website. Thus if nobody visits, ?>the cron never runs.

Answer 2

Here is what I do to validate orders based on a CRON task.
$order->payment_complete('transaction ID string'); //validate payment
wc_reduce_stock_levels($order->get_id()); //reduce stock
$woocommerce->cart->empty_cart(); //empty cart
$order->update_status('completed', 'A order note string'); //change order statyus
I believe that you don't need the "wc-" prefix.
Are you sure that your scheduled event is working? and that $orders is filled? Please test your method without the schedule first.
