How to Embed Asynchronous Content with hinclude.js

Controllers can be embedded asynchronously using the hinclude.js JavaScript library. As the embedded content comes from another page (or controller for that matter), Symfony uses a version of the standard render() function to configure hinclude tags:

.. configuration-block::

    .. code-block:: twig

        {{ render_hinclude(controller('...')) }}
        {{ render_hinclude(url('...')) }}

    .. code-block:: php

        <?php echo $view['actions']->render(
            new ControllerReference('...'),
            array('renderer' => 'hinclude')
        ) ?>

        <?php echo $view['actions']->render(
            $view['router']->generate('...'),
            array('renderer' => 'hinclude')
        ) ?>

Note

hinclude.js needs to be included in your page to work.

Note

When using a controller instead of a URL, you must enable the Symfony fragments configuration:

.. configuration-block::

    .. code-block:: yaml

        # app/config/config.yml
        framework:
            # ...
            fragments: { path: /_fragment }

    .. code-block:: xml

        <!-- app/config/config.xml -->
        <?xml version="1.0" encoding="UTF-8" ?>
        <container xmlns="http://symfony.com/schema/dic/services"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xmlns:framework="http://symfony.com/schema/dic/symfony"
            xsi:schemaLocation="http://symfony.com/schema/dic/services
                http://symfony.com/schema/dic/services/services-1.0.xsd
                http://symfony.com/schema/dic/symfony http://symfony.com/schema/dic/symfony/symfony-1.0.xsd">

            <!-- ... -->
            <framework:config>
                <framework:fragment path="/_fragment" />
            </framework:config>
        </container>

    .. code-block:: php

        // app/config/config.php
        $container->loadFromExtension('framework', array(
            // ...
            'fragments' => array('path' => '/_fragment'),
        ));

Default content (while loading or if JavaScript is disabled) can be set globally in your application configuration:

.. configuration-block::

    .. code-block:: yaml

        # app/config/config.yml
        framework:
            # ...
            templating:
                hinclude_default_template: hinclude.html.twig

    .. code-block:: xml

        <!-- app/config/config.xml -->
        <?xml version="1.0" encoding="UTF-8" ?>
        <container xmlns="http://symfony.com/schema/dic/services"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xmlns:framework="http://symfony.com/schema/dic/symfony"
            xsi:schemaLocation="http://symfony.com/schema/dic/services
                http://symfony.com/schema/dic/services/services-1.0.xsd
                http://symfony.com/schema/dic/symfony http://symfony.com/schema/dic/symfony/symfony-1.0.xsd">

            <!-- ... -->
            <framework:config>
                <framework:templating hinclude-default-template="hinclude.html.twig" />
            </framework:config>
        </container>

    .. code-block:: php

        // app/config/config.php
        $container->loadFromExtension('framework', array(
            // ...
            'templating' => array(
                'hinclude_default_template' => array(
                    'hinclude.html.twig',
                ),
            ),
        ));

You can define default templates per render() function (which will override any global default template that is defined):

.. configuration-block::

    .. code-block:: twig

        {{ render_hinclude(controller('...'),  {
            'default': 'default/content.html.twig'
        }) }}

    .. code-block:: php

        <?php echo $view['actions']->render(
            new ControllerReference('...'),
            array(
                'renderer' => 'hinclude',
                'default'  => 'default/content.html.twig',
            )
        ) ?>

Or you can also specify a string to display as the default content:

.. configuration-block::

    .. code-block:: twig

        {{ render_hinclude(controller('...'), {'default': 'Loading...'}) }}

    .. code-block:: php

        <?php echo $view['actions']->render(
            new ControllerReference('...'),
            array(
                'renderer' => 'hinclude',
                'default'  => 'Loading...',
            )
        ) ?>
