limit user

hi
i add this code in class-gens-raf-public.php and change function gens_create_send_coupon and work:

public function gens_create_send_coupon($order_id) {
		$rafID = esc_attr(get_post_meta( $order_id, '_raf_id', true));
		// Get id of user that made order so that user cant use his own ref link.
		$order = new WC_Order( $order_id );
		$order_user_id = $order->get_user_id();
		$gens_users = get_users( array(
			"meta_key" => "gens_referral_id",
			"meta_value" => $rafID,
			"number" => 1, 
			"fields" => "ID"
		) );
		$user_id = $gens_users[0];
		
                // added code
		$user_info = get_userdata($user_id);
		$user_email = $user_info->user_email;
		$couponargs = array( 'post_type' => 'shop_coupon','posts_per_page' => -1, 'meta_key' => 'customer_email', 'meta_value' => $user_email);
		$mycoupons = get_posts( $couponargs );
		$count = count($mycoupons);
		//end

		// user ref exists, refID as well, and user is not using his own referral link ? If all good, proceed.
		if ( $gens_users && !empty($rafID) && ($user_id != $order_user_id) && $count < 2) {
			// Generate Coupon and returns it
			$coupon_code = $this->generate_coupons( $user_id  ); 
			// Send via Email
			$this->gens_send_email( $user_id, $coupon_code );
		}
		return $order_id;
	}
