How to trigger wordpress / woocommerce email on payment gateway plugin?

4 Views

I have made a wordpress plugin. It handles a new payment gateway with credit card. After the succesfull transaction I close the order but cannot send email. I tried everything. I tried to call the mailer on init, but it fails on error.log:

PHP Fatal error: Call to a member function get_order_number() on
boolean in
……/wp-content/plugins/woocommerce/includes/emails/class-wc-email-customer-processing-order.php
on line 58

I tried to make a new WC_simplepay(); on init, it fails with class not found.

I tried the same mail sending in the class with new function, and call it from the constructor with $this->functionname(); It works, mail sent, but the payment provider (or me) cannot call this from url (this is why I check the request param), because the class only loads when you are in the checkout page.

I tried the global $woocommerce … etc solution but also not working in the init part, only inside the class.

Starting of the plugin code: 

    add_action('plugins_loaded', 'woocommerce_simplepay_init', 0);

    function woocommerce_simplepay_init(){
        if(!class_exists('WC_Payment_Gateway')) return;

        if ($_REQUEST['REFNOEXT']!='')
        {
            /* .... here are some code regarding the gateway provider ,logging, etc... fully working */
            $order_id = explode('_',$_REQUEST['REFNOEXT']);
            $order = new WC_Order($order_id[0]);
            $order->update_status('processing');
            WC()->mailer()->emails['WC_Email_Customer_Processing_Order']->trigger($order_id[0]); // this is generating the error
        }

    class WC_simplepay extends WC_Payment_Gateway{

        public function __construct(){
...

So basically how can I close the order, send email to the customer and handle the provider thingies with this class using remote URL calls?

  1. You are hooking into the wrong action, I recommend you to hook on init because it’s executed after all plugins (including woocommerce) has been loaded. 

    add_action('init', 'woocommerce_simplepay_init');

function woocommerce_simplepay_init(){
    if(!class_exists('WC_Payment_Gateway')) return;

    if ($_REQUEST['REFNOEXT']!='')
    {
        $order_id = explode('_',$_REQUEST['REFNOEXT']);
        $order = new WC_Order($order_id[0]);
        $order->update_status('processing');
        WC()->mailer()->emails['WC_Email_Customer_Processing_Order']->trigger($order_id[0]); // this is generating the error
    }

    But since you’re using a Class, I believe that’s better to include this function inside a class.

    Init hook reference
