Call PHP function after WooCommerce order completed using woocommerce_order_status_completed hook

WooCommerce is an extendable WordPress plugin to start an eCommerce store. In this post, I am going to tell you how to call PHP function after WooCommerce order completed.

WooCommerce already contains lots of its own action hooks and filter hooks so that developers can extend the features and functionality of this plugin programmatically. Using these hooks, you can develop add-ons for WooCommerce.

There is an action hook available for WooCommercethat can call a function after order status completed. The action hook is woocommerce_order_status_completed which is one of the most useful action hooks to develop add-ons for WooCommerce.

Using woocommerce_order_status_completed action hook we can easily call PHP function after WooCommerce order completed.

Let’s see the code snippet.

First of all, create our custom PHP function:

// define woocommerce_order_status_completed callback function
function call_order_status_completed( $array ) { 
    // Write your code here
};

And then call it with the action hook woocommerce_order_status_completed:

add_action( 'woocommerce_order_status_completed', 'call_order_status_completed', 10, 1);

Complete code to call PHP function after WooCommerce order completed

So below is our complete example code:

// define woocommerce_order_status_completed callback function
function call_order_status_completed( $array ) { 
    // Write your code here
};
