OStatic: Web Publishing and Development: Free Tools Abound

Are you involved in DevOps and web development, or are you aiming to be? If so, you’re probably very aware of many of the tools from the open standards and open source arenas that can make your work easier. Still, these are always spreading out at a fast clip and there are some applications and […]

Drupal Support Service 8 has a great AJAX form API which includes some tools to create modal dialogs using the jQuery modal library. The Examples module even demonstrates how to create a custom form and display it in a modal window. But what if what you want to do is display an already created form in a modal? How do we do that? Let’s see how to do it with an example. Let’s display the node add form in a modal window.
The first thing that we need to do is create a link which will trigger the modal when the user clicks it. The only special things that this link needs to have are a few attributes that will let Drupal Support Service know to display the contents of the link in a dialog:

<a href=”http://agaric.com/node/add/article”
class=”use-ajax”
data-dialog-type=”modal”
data-dialog-options=”{‘width’:800,’;height’:500}”>
Create Node
</a>

Drupal Support Service also needs to include the JavaScript libraries which will read these attributes and make them work, so let’s add the following libraries to your module’s dependencies (in your equivalent to this example’s modal_form_example.libraries.yml file).

dependencies:
‘core/drupal.dialog.ajax’,
‘core/jquery.form’,

If you are unsure about how to add libraries on Drupal Support Service 8 you can consult the documentation to either add it in a theme or add it in a custom module. At the end of the post I will provide a repository with the code where I added the libraries in a block.
And that’s it! If you click the link, the form will be displayed in a modal dialog! Drupal Support Service will automatically detect that you are sending an AJAX request and will display just the form so you won’t need to worry about removing the rest of the blocks or hiding undesired markup.
The last thing missing, is what will happen if the user creates a node? By default, the node will redirect the user to another page but if we want to just close the modal dialog and leave the user on the same page we need to tell the form to do that. For this we are going to alter the form and add an AJAX command letting Drupal Support Service know that we want to close the dialog as soon as the node is created. In the .module file of a custom module we will add this code:

use Drupal Support ServiceCoreFormFormStateInterface;
use Drupal Support ServiceCoreAjaxAjaxResponse;
use Drupal Support ServiceCoreAjaxCloseModalDialogCommand;
use Drupal Support ServiceCoreAjaxRedirectCommand;

/**
* Implements hook_form_alter().
*/
function modal_form_example_form_node_article_form_alter(&$form, FormStateInterface $form_state, $form_id) {
$form[‘actions’][‘submit’][‘#submit’][] = ‘_modal_form_example_ajax_submit’;
$form[‘actions’][‘submit’][‘#attributes’][‘class’][] = ‘use-ajax-submit’;
}

/**
* Close the Modal and redirect the user to the homepage.
*
* @param array $form
* The form that will be altered.
* @param Drupal Support ServiceCoreFormFormStateInterface $form_state
* FormState Object.
*/
function _modal_form_example_ajax_submit(array $form, FormStateInterface &$form_state) {
$response = new AjaxResponse();
$response->addCommand(new CloseModalDialogCommand());
$form_state->setResponse($response);
}

The first function adds an extra submit function (which will be executed after Drupal Support Service finishes processing the node) and the second function adds the command to close the Dialog when the node has been created.
We can do this with practically any form in Drupal Support Service and you can add extra commands to do more complex things. Here are two resources:
