Change email send to the administrator of the opencart store when they get an order

This Opencart tutorial shows how to change and customize emails send out to the store administrator when they get the new order in the OpenCart store. Normally Opencart just sends an email with fewer details like below:

You have received an order.

Order ID: 1088
Date Added: 11/02/2019
Order Status: Complete

Products
1x .... $0.00

Order Totals
Sub-Total: $0.00
Total: $0.00

Let's change that email to send full details like the one that customers get.

Open catalog/controller/mail/order.php and remove the alert method and replace it with the below alert method.

// Admin Alert Mail
public function alert(&$route, &$args) {
    if (isset($args[0])) {
        $order_id = $args[0];
    } else {
        $order_id = 0;
    }
    
    if (isset($args[1])) {
        $order_status_id = $args[1];
    } else {
        $order_status_id = 0;
    }	
    
    if (isset($args[2])) {
        $comment = $args[2];
    } else {
        $comment = '';
    }
    
    if (isset($args[3])) {
        $notify = $args[3];
    } else {
        $notify = '';
    }

    $order_info = $this->model_checkout_order->getOrder($order_id);
    
    if ($order_info && !$order_info['order_status_id'] && $order_status_id && in_array('order', (array)$this->config->get('config_mail_alert'))) {	

        // Check for any downloadable products
