How to allow users to use specific controller actions (e.g. send form) in maintenance mode?

Question

I created a custom maintenance page which appears after setting the maintenance.flag file.

The custom page has a few forms which I copied from the normal page, but they are not working. Validation and date time picking works but If I send the form then I get 503 service unavailable in the network analysis.

I need the forms so that users can contact me and order stuff while the page is down.

It works without problems on the main page if the maintenance.flag is not set?

How can I allow the form on maintenance mode?

---

I tried to allow Mage by putting the following code at the top in errors/default/page.phtml:

error_reporting(E_ALL | E_STRICT);
$mageFilename = MAGENTO_ROOT . '/app/Mage.php';
require_once $mageFilename;
Mage::setIsDeveloperMode(true);
ini_set('display_errors', 1);
umask(0);
Mage::app();

But I still can't access any controller and get 503 Service Unavailable in the developer console after attempting to submit the form.

Please describe the steps needed to allow specific controllers in maintenance mode. I try to let users subscribe to my newsletter and send the contact form, but they should not be allowed to shop.

EDIT: This question is obviously not a duplicate of (1.9.0.1 Maintenance Mode) because I don't ask how to put magento in maintenance mode. Learn english please @MagenX.

Answer 1

As your website is in maintenance mode then other codes will not work. If you check the index.php file in your magento root folder then you can find that magento will not run further when they find maintenance file in your root directory.

You can solve this by creating a custom php file in your magento root and include the Mage.php after that you can use the magento functions according to your requirement.

METHOD 2

You will get route name for the pages you want to consider by following code:

$routename = Mage::app()->getRequest()->getRouteName();

After that you need to put the condition like below:

if (file_exists($maintenanceFile) && $routename != 'YOUR_ROUTE_NAME') {
    include_once dirname(__FILE__) . '/errors/503.php';
    exit;
}

You can get your routename(YOUR_ROUTE_NAME) by echo $routename just above the below code:

if (file_exists($maintenanceFile) && $routename != 'YOUR_ROUTE_NAME')

METHOD 3:

If Method 2 was not working, then try:

$routename = parse_url($_SERVER['REQUEST_URI']);

if (file_exists($maintenanceFile) && $routename['path'] !== "/newsletter/subscriber/new/") { ... }

You can get your routename(YOUR_ROUTE_NAME) by echo $routename['path'] just above the below code:

if (file_exists($maintenanceFile) && $routename['path'] != 'YOUR_ROUTE_NAME')

Answer 2

By default, You can not allow this. If you check Magento index.php file, you will found the below code:

if (file_exists($maintenanceFile)) {
    include_once dirname(__FILE__) . '/errors/503.php';
    exit;
}

You can add your Custom condition here with Custom URL check.

Hope this help!!
