How to add custom widgets to Magento 2?

A widget is a small informational or functional block located in a narrow column of the site. It can be a button, banner, search bar, text block, and more. Widgets can be displayed on all pages of the site and are constantly in sight of the user, which means they are ideal for posting important information.

Setting up widgets in Magento is a complex process that requires some work with code. Here is a step-by-step guide for setting up custom widgets in Magento.

How to create a custom widget in Magento 2 and edit its parameters?

Step 1. The first step is to declare the widget.

The code below must be inserted into the etc/widget.xml file:

<widgetsxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Widget:etc/widget.xsd">

    <widgetclass="OrangeCompany\Learning\Block\Widget\Test"id="orange_test_widget">

        <label>My New Widget</label>

        <description>This is a test widget!!!</description>

        <parameters>

            ...

        </parameters>

        <containers>

            ...

        </containers>

    </widget>

</widgets>

In addition, we need to create a dependency on Magento_Widget in the module.xml file.

To do this, open the etc / module.xml file and paste the following code:

...

<sequence>

    <modulename="Magento_Widget"/>

</sequence>

...

Step 2. The next step is to add widget parameters.

There are some field parameters you can use:

• text
• select
• multiselect
• block.

Say, you need to add the text and select fields. Use the following code:

<widgetsxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Widget:etc/widget.xsd">

    <widgetclass="OrangeCompany\Learning\Block\Widget\Test"id="orange_test_widget">

        ...

        <parameters>

            <parametername="title"xsi:type="text"required="true"visible="true"sort_order="10">

                <label>Label</label>

            </parameter>

            <parametername="size"xsi:type="select"visible="true"required="true"sort_order="20">

                <labeltranslate="true">Size</label>

                <options>

                    <optionname="s"value="S">

                        <label>S</label>

                    </option>

                    <optionname="m"value="M"selected="true">

                        <label>M</label>

                    </option>

                    <optionname="l"value="L">

                        <label>L</label>

                    </option>

                </options>

            </parameter>

        </parameters>

    </widget>

</widgets>

Step 3. On this step, you need to check the widget.

To do this, run the following commands:

bin/magento module:disable Vendor_Module

bin/magento module:enable Vendor_Module

Replace Vendor_Module with the module name.

These commands allow you to apply the module dependency declared in the module.xml file. Then clear the cache, and a new widget will be available for selection:

When the widget type and layout location are selected, you will see the options of the widget:

Step 4. Now we need to create the block class provided on the widget’s initialization, which is responsible for rendering it on the frontend page.

Open OrangeCompany/Learning/Block/Widget/Test and use the following code:

namespaceOrangeCompany\Learning\Block\Widget;

useMagento\Framework\View\Element\Template;

useMagento\Widget\Block\BlockInterface;

classTestextendsTemplateimplementsBlockInterface

{

    protected$_template="widget/test.phtml";

}

Step 5.  Now you need to create the template.

This template will be used to show the data of the widget on the frontend page.

In the OrangeCompany / Learning / view / frontend / templates / widget / test.phtml file, use this code:

<?php

/** \OrangeCompany\Learning\Block\Widget\Test $block */

?>

<h3><?=$block->escapeHtml($block->getData('title'))?></h3>

<h3><?=$block->escapeHtml(__('Size:'))?><?=$block->escapeHtml($block->getData('size'))?></h3>

Step 6. The last step is to clean the cash.

Use bin/magento cache:clean command to clean the cash.

That's it. Now your Magento 2 widget will be shown on the frontend page.

Using widgets on your storefront can increase user engagement. For example, our Blog Pro extension can add widgets with categories, recent posts, and comments to your blog page. As a result, highlighted articles will get more attention.
