Problem/Motivation

The current implementation in RenderElement::preRenderAjaxForm() destroys any url options when a Url object is passed for form ajax. This was the root cause of probably 40+ hours of ctools debugging and a huge thanks to dawehner for ultimately sorting it. If a Url object is generated with options in place, we should respect that and not require they be restated in ['#ajax']['options'] manually.

Proposed resolution

Instead of overwriting the Url objects options so whatever is set in ['#ajax']['options'] (which could be empty) simply iterate over the options array and set individual options which will preserve options passed with the Url object.

Remaining tasks

Provide patch
Write tests
Get it done

User interface changes

None

API changes

Should not affect existing core implementations, and might smooth the way for some contrib modules as they begin implementing work here.

Data model changes

None.

A simple patch to demonstrate the idea.

What I tried to do:


        $actions['previous']['#ajax'] = [
          'callback' => '::ajaxPrevious',
          'url' => Url::fromRoute($this->getRouteName(), $parameters, ['query' => \Drupal::request()->query->all() + [FormBuilderInterface::AJAX_FORM_REQUEST => TRUE]]),
        ];

What I have to ACTUALLY do to get it to work:


        $actions['previous']['#ajax'] = [
          'callback' => '::ajaxPrevious',
          'url' => Url::fromRoute($this->getRouteName(), $parameters),
          'options' => ['query' => \Drupal::request()->query->all() + [FormBuilderInterface::AJAX_FORM_REQUEST => TRUE]],
        ];

Note: Don't even try passing a string to the 'url' key... that will definitely not work out for you. (also seems like a problem, since you HAVE to pass a Url object for this magical incantation to work)

I'm not sure how to write a test for this. Can we have steps to reproduce here? Maybe those will help to write a test.

Version: 9.5.x-dev » 11.x-dev

Drupal core is moving towards using a “main” branch. As an interim step, a new 11.x branch has been opened, as Drupal.org infrastructure cannot currently fully support a branch named main. New developments and disruptive changes should now be targeted for the 11.x branch. For more information, see the Drupal core minor version schedule and the Allowed changes during the Drupal core release cycle.

Version: 11.x-dev » main

Drupal core is now using the main branch as the primary development branch. New developments and disruptive changes should now be targeted to the main branch.
