Backend Redirect Bundle is an extension for Contao CMS version 4.

Installation

Use Composer to add the bundle to your Contao application:

composer require ameotoko/backend-redirect

Usage

This bundle adds a backend route to your application (/contao/redirect by default). You can supply a query string to it, and it will redirect you to a correspondent backend module after adding proper request token and ref. If you have to login, you'll be redirected to /contao/login first.

Why?

Sometimes you might want to let your backend users to access a record editing form, using a direct link, like /contao?do=members&act=edit&id=42. For instance, your application might be sending notifications to your editors, where they can click on such a link in the email and proceed directly to editing the record.

Prior to version 5.1, Contao's backend firewall will not let you do it directly – it will force your editors to go through a confirmation screen like this:

which is not a good UX for your editors. With this extension, you can give them links like this:

https://example.com/contao/redirect?do=user&act=edit&id=1

It will redirect to:

https://example.com/contao?do=user&act=edit&id=1&rt=a48be7155094538da5fe2.dO1lxYXxmvHGRIblveDcaZfHJMYJpQbWLaMMtb1oO8g.E4QDt-6hwr-pd9Sn8IGROeW2e544_36kcptUx-4QXvodviGcwqvbrv8o9Q

NOTES:

1. This will only work for idempotent actions that do not directly change or delete database records, such as e.g. ?act=edit. In other cases, request token will not be added, and Contao's token check will still kick in.
2. Starting from version 5.1, Contao does not require request token for idempotent actions anymore, so you do not need this bundle (see contao/contao#5461).

Configuration

You can customize the URL path using route prefix:

# config/routes.yaml
app_redirect:
    resource: '@AmeotokoBackendRedirectBundle/Resources/config/_definition.yaml'
    prefix: /contao/my-redirect

The endpoint will now be https://example.com/contao/my-redirect.
