Disable Open Cart 3 check out on sundays - php

Question

I have a store which is set up with Open Cart 3. I want to disable the checkout on Sundays. I have tried the following code but it doesn't seem to be working.
I added the code to following file cataloge/controller/checkout/checkput.php
class ControllerCheckoutCheckout extends Controller {
public function index() {
// Validate cart has products and has stock.
if ((!$this->cart->hasProducts() && empty($this->session->data['vouchers'])) || (!$this->cart->hasStock() && !$this->config->get('config_stock_checkout'))) {
$this->response->redirect($this->url->link('checkout/cart'));
}
if (date("l") == "Sunday") {
$this->response->redirect($this->url->link('checkout/cart'));
$this->session->data['error'] = 'Sorry we are closed on Sundays';
}
Here is the full code before I added my line;
<?php
class ControllerCheckoutCheckout extends Controller {
public function index() {
// Validate cart has products and has stock.
if ((!$this->cart->hasProducts() && empty($this->session->data['vouchers'])) || (!$this->cart->hasStock() && !$this->config->get('config_stock_checkout'))) {
$this->response->redirect($this->url->link('checkout/cart'));
}
// Validate minimum quantity requirements.
$products = $this->cart->getProducts();
foreach ($products as $product) {
$product_total = 0;
foreach ($products as $product_2) {
if ($product_2['product_id'] == $product['product_id']) {
$product_total += $product_2['quantity'];
}
}
if ($product['minimum'] > $product_total) {
$this->response->redirect($this->url->link('checkout/cart'));

}
Could anyone have any idea why this doesn't work or another way of disabling the checkout on Sundays?

Answer 1

If you put this line below befoe the redirection, the error message will show up.
$this->session->data['error'] = 'Sorry we are closed on Sundays';
here is code after the change
class ControllerCheckoutCheckout extends Controller {
public function index() {
// Validate cart has products and has stock.
if ((!$this->cart->hasProducts() && empty($this->session->data['vouchers'])) || (!$this->cart->hasStock() && !$this->config->get('config_stock_checkout'))) {
$this->response->redirect($this->url->link('checkout/cart'));
}
if (date("l") == "Sunday") {
$this->session->data['error'] = 'Sorry we are closed on Sundays';
$this->response->redirect($this->url->link('checkout/cart'));
}
