Woocommerce - Allowing Order Again for different statuses - php

Question

I'm looking to allow the Order Again functionality to all statuses. By default WooCommerce only allows orders with a status of COMPLETED this functionality. It seems to be a two step process as the first step requires the button being shown to the user, this is completed by editing this file:
wc-template-functions.php
With this snippit of code:
function woocommerce_order_again_button( $order ) {
//if ( ! $order || ! $order->has_status( 'completed' ) || ! is_user_logged_in() ) {
// Allow 'Order Again' at all times.
if ( ! $order || ! is_user_logged_in() ) {
return;
}
wc_get_template( 'order/order-again.php', array(
'order' => $order
) );
}
By commenting out the validation of the $order->has_status() method, I'm able to show the button on the page. However, when trying clicking the Order Again button, it still does a check before adding the items to the cart.
Can anyone tell me where this code is stored to do a preliminary check on the $order->has_status()?

Answer 1

You can simply add difference order status to filter woocommerce_valid_order_statuses_for_order_again.
add_filter( 'woocommerce_valid_order_statuses_for_order_again', 'add_order_again_status', 10, 1);
function add_order_again_status($array){
$array = array_merge($array, array('on-hold', 'processing', 'pending-payment', 'cancelled', 'refunded'));
return $array;
}

Answer 2

Since the OP's original question, WooCommerce has added a filter to these statuses. The function can be found in includes/wc-template-functions.php
https://docs.woocommerce.com/wp-content/images/wc-apidocs/function-woocommerce_order_again_button.html
/**
* Display an 'order again' button on the view order page.
*
* #param object $order
* #subpackage Orders
*/
function woocommerce_order_again_button( $order ) {
if ( ! $order || ! $order->has_status( apply_filters( 'woocommerce_valid_order_statuses_for_order_again', array( 'completed' ) ) ) || ! is_user_logged_in() ) {
return;
}
wc_get_template( 'order/order-again.php', array(
'order' => $order,
) );
}
So in order to filter the statuses you could do something like this (wc_get_order_statuses() just returns all order statuses in this case; you can set the $statuses variable to an array of an statuses you would like):
add_filter('woocommerce_valid_order_statuses_for_order_again', function( $statuses ){
$statuses = wc_get_order_statuses();
return $statuses;
}, 10, 2);
