HumHub Modals are based upon Bootstrap Modals and can be used to render forms or user feedback as confirmation requests or other information. The Javascript module ui.modals provides some additional functaionality for creating and loading modals.

Global Modal

By default an empty global modal with the id globalModal is available in the default HumHub layout. The instance for this modal is available under the namespace and can be reused by other modules at any time as follows

var modal = require('ui.modal');

// load the result of someUrl into the global modal;
Create new Modals:

In most cases the global modal should be sufficient for your usecases. In some cases you'll need to create an independent modal which can be achieved by using the modal.get() function, which expects an modal id as fist argument and will search for the existence of a modal with the given id and will create a new one in case there is no such an modal.

var myModal = modal.get('myModalId');

You can also manipulate your modal content by means of the following functions:

  • setDialog(content): sets the dialog part of your modal, the content should be a string, node or client.Response. In case of a response instance, it should either be an html response or a json response with output markup.
  • setBody(content): sets the body part of your modal
  • setContent(content): sets the content part of your modal
  • setHeader(content): sets the modal header title
  • setFooter(content): setts the modal footer
  • set(options): sets the modal options header, body, content, footer and bootstrap modal options (e.g. backdrop, keyboard.

Note: Since Modals are derived from ui.widget.Widget you can also configure your custom modal by using data-* options.

Load Remote Modal

To load remote content into your modal you can either manually load it by calling the load function of your modal or use the load action of the modal module.

Modal load

A call to your modals load(url, options, originalEvent) loads the result of url into your modal by means of a GET request. The response markup has to be the modal-dialog part of the modal. {
    // Called after your modal was filled with the response
}).catch(function(e) {
    module.log.error(e, true);
Returned view:
<?php ModalDialog::begin(['header' => 'My Title']) ?>
    <div class="modal-body"><!-- ... --></div>
    <div class="modal-footer"><!-- ... --></div>
<?php ModalDialog::end() ?>

Info: By default the load function expects dataType: html, if you require to return json content instead, your server response has to provide an output part with the rendered modal dialog.

Modal load action

If you just want to trigger a simple modal load event after clicking a button, you can use the ui.modal.load action as follows

<!-- loads the result of $someUrl to the global modal -->
<button data-action-click="ui.modal.load" data-action-url="<?= $someUrl ?>">Load my Modal!</button>

<!-- loads the result from $someJsonUrl and insert the response.output to the global modal -->
<button data-action-click="ui.modal.load" data-action-url="<?= $someJsonUrl ?>" data-type="json">Load my Modal!</button>

<!-- loads the result of $someJsonUrl and insert the response.output to a custom modal -->
<button data-action-click="ui.modal.load" data-action-url="<?= $someJsonUrl ?>" data-modal-id="myId">Load my Modal!</button>

Tip: If your button is rendered within your custom modal itself you can omit the data-modal-id setting.

Modal post

Similar to the load function you can use the post modal function or action to submit a post request., {data: {somePostData: 'value' } });


<button data-action-click="" data-action-url="<?= $someUrl ?>">Post Modal!</button>

Modal submit

To render the result of a form submit into the global modal, your submit button should use the ui.modal.submit action on your submit button. This action will use the client.submit to submit the given form and set the result into the global modal.

Modal Confirm

By using the modal.confirm() function, you can request a user confirmation as follows

var options = {
    header: 'Please confirm this action!'
    body: 'Do you really want to execute this action?',
    confirmText: 'Yes',
    cancelText: 'No'

modal.confirm(options).then(function(confirmation) {
    if(confirmation) {
        //do something

Note: You do not have to provide all texts, there are default texts for your confirm modal.

Action confirm

<button data-action-click="someAction" 
        data-action-confirm="Do you really want to execute this action?"
        data-action-confirm-header="Please confirm this action!"
    Do something!
