Developing Dashboard Widgets

Along with the basic widgets which will come native with ExpressionEngine Pro, each third-party add-on can provide multiple widgets to show pertinent information to users.

Widgets which are shipped with add-ons can have .html or .php extension and have to be placed into widgets sub-directory of the add-on. They are then installed automatically when the add-on is installed or updated.

Users can also create widgets using ExpressionEngine template manager.

PHP Widgets

In order for an add-on to provide dashboard widgets, it needs to contain widgets folder inside its main directory, which will contain the widget files.

All widgets are required to implement ExpressionEngine\Addons\Pro\Service\Dashboard\DashboardWidgetInterface. The easiest way to achieve that is to make widget extend abstract class ExpressionEngine\Addons\Pro\Service\Dashboard\AbstractDashboardWidget.

Each widget should have namespace definition, which should consist of the add-on’s namespace as defined in addon.setup.php followed by \Widgets.

The class name should match the file name with first letter capitalized.

Example PHP Widget:

<?php

/**
* namespace is required and must be add-on's namespace + 'Widgets'
* 
*/
namespace Addons\Pro\Widgets;

use ExpressionEngine\Addons\Pro\Service\Dashboard;

class DashboardWidget extends Dashboard\AbstractDashboardWidget implements Dashboard\DashboardWidgetInterface {

    public $width = 'full'; //optional, if you want full width widget
    public $class= '';//optional; extra CSS class you want to give to widget container

    /**
    * required
    */
    public function getTitle() : string 
    {
        return lang('members'); //widget title/header/top line
    }

    /**
    * required
    * must return the inner HTML for widget
    */
    public function getContent() : string
    {
        $vars = [];
        $vars['can_access_members'] = ee('Permission')->can('access_members');

        return ee('View')->make('pro:widgets/members')->render($vars);
    }

    /**
    * optional
    * used to generate extra content shown at top right corner of widget
    */
    public function getRightHead() : string
    {
        return ee('View')->make('pro:widgets/_embed/member_buttons')->render();
    }

} 

PHP widgets are installed when add-on is installed or updated.

HTML Widgets

HTML widgets utilize the ExpressionEngine template engine. Therefore, they can contain any template tags and need to return HTML that will be displayed inside the widget.

HTML widgets are required to have this tag as first line: {widget title="Widget Title"}

Parameter Values Description
title String Required. Widget header
class String Extra CSS class to add to widget wrapper
width full/half Widget width. Default is ‘half’.

Example HTML widget: {widget class=”widget–support” title=”ExpressionEngine Support” width=”half”}

<p>Get <b>direct</b>, <b>fast</b>, <b>unlimited</b> support from the same team that builds your favorite CMS.</p>

<p><a href="https://expressionengine.com/support" target="_blank" class="button button--default">Learn More</a></p>

HTML add-on widgets are installed when add-on is installed or updated.

Template widgets

You can create custom widgets specifically for your site by creating a template group named pro-dashboard-widgets and adding templates inside of it.

Templates for Dashboard Widgets need to follow the syntax of HTML widgets.

Example HTML widget created as a template ( pro-dashboard-widgets/widget-name.html):

{widget title="Recent Entries" width="half"}
{exp:channel:entries channel="news" limit="10"}
    <h2>{title}</h2>
    {body}
{/exp:channel:entries}

Unlike add-on widgets, template widgets are installed when dashboard layout is updated.
