how to automatically delete order in wordpress - php

Question

I wanted to know how to automatically delete an order when a user ordering a Specific product/category if it was in pending in 5m.
I have this code but when I add it to my function.php it doesn't work.
function update_order_status( $order_id ) {
$order = new WC_Order( $order_id );
$order_status = $order->get_status();
if ('pending' == $order_status ) {
$current_time = date('h:i:s');
sleep(600);
wp_delete_post($order_id,true);
}
}

You can use the CRON job and then get all orders with pending status and then check their order date with the current date and delete.
Add custom 5-minute cron schedules by using WC cron_schedules hook
function add_five_minute_cron_schedules($schedules){
if( !isset( $schedules["five_minute"] ) ){
$schedules["five_minute"] = array(
'interval' => 5*60,
'display' => __('Once every 5 minutes')
);
}
return $schedules;
}
add_filter('cron_schedules','add_five_minute_cron_schedules');
Scheduled your CRON on WP init Hook.
if( ! wp_next_scheduled( 'remove_pending_order_after_five_minute' ) ){
wp_schedule_event( time(), 'five_minute', 'remove_pending_order_after_five_minute' );
}
//Hook into that action that'll fire every 5 minutes.
add_action( 'remove_pending_order_after_five_minute', 'remove_pending_order_after_five_minute_callback' );
function remove_pending_order_after_five_minute_callback(){
// get all pending orders that created in the last 5 minutes.
$args = array(
'post_status' => array( 'wc-processing', 'wc-pending', 'wc-on-hold' ),
'date_created' => '<' . ( time() - 300 ),
'posts_per_page' => -1
);
$orders = wc_get_orders($args);
if( !empty( $orders ) ){
// Loop through each $order objects.
foreach( $orders as $order ){
$order_id = method_exists( $order, 'get_id' ) ? $order->get_id() : $order->id;
$order = wc_get_order( $order_id );
if ( $order && sizeof( $order->get_items() ) > 0 ) {
foreach( $order->get_items() as $item ) {
if( has_term( 'charkh', 'product_cat', $item->get_product_id() ) ) {
wp_delete_post( $order_id );
break;
}
}
}
}
}
}
This code goes to active theme functions.php file. Tested and works.
