How to Add Custom Image Attribute in Magento 2 Category (2.3+ Supported)

Magento 2 out of the box provides a feature to upload a category image. That category image is displayed on the product listing page. However, Sometimes clients want a functionality to upload another image in a category. For example, the client wants to display an icon of a category in the menu or somewhere else on the website.

To fulfill those requirements we have to provide options in the category to add an image. In this post, we will see how to add custom image attribute in Magento 2 category.

Add Custom Image Attribute in Magento 2 Category

Create Patch AddIconCategoryAttribute.php under app/code/Codextblog/Demo/Setup/Patch/Data directory. Add below code in that file.

<?php
namespace Codextblog\Demo\Setup\Patch\Data;

use Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface;
use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Framework\Setup\Patch\DataPatchInterface;
use Magento\Framework\Setup\Patch\PatchRevertableInterface;

class AddIconCategoryAttribute implements DataPatchInterface, PatchRevertableInterface
{

    /**
     * @var ModuleDataSetupInterface
     */
    private $moduleDataSetup;
    /**
     * @var EavSetupFactory
     */
    private $eavSetupFactory;

    /**
     * Constructor
     *
     * @param ModuleDataSetupInterface $moduleDataSetup
     * @param EavSetupFactory $eavSetupFactory
     */
    public function __construct(
        ModuleDataSetupInterface $moduleDataSetup,
        EavSetupFactory $eavSetupFactory
    ) {
        $this->moduleDataSetup = $moduleDataSetup;
        $this->eavSetupFactory = $eavSetupFactory;
    }

    /**
     * {@inheritdoc}
     */
    public function apply()
    {
        $this->moduleDataSetup->getConnection()->startSetup();
        /** @var EavSetup $eavSetup */
        $eavSetup = $this->eavSetupFactory->create(['setup' => $this->moduleDataSetup]);
        $eavSetup->addAttribute(
            \Magento\Catalog\Model\Category::ENTITY,
            'icon',
            [
                'type' => 'varchar',
                'label' => 'Icon',
                'input' => 'image',
                'sort_order' => 333,
                'source' => '',
                'global' => ScopedAttributeInterface::SCOPE_STORE,
                'visible' => true,
                'required' => false,
                'user_defined' => false,
                'default' => null,
                'group' => 'General Information',
                'backend' => 'Magento\Catalog\Model\Category\Attribute\Backend\Image'
            ]
        );

        $this->moduleDataSetup->getConnection()->endSetup();
    }

    public function revert()
    {
        $this->moduleDataSetup->getConnection()->startSetup();
        /** @var EavSetup $eavSetup */
        $eavSetup = $this->eavSetupFactory->create(['setup' => $this->moduleDataSetup]);
        $eavSetup->removeAttribute(\Magento\Catalog\Model\Category::ENTITY, 'icon');

        $this->moduleDataSetup->getConnection()->endSetup();
    }

    /**
     * {@inheritdoc}
     */
    public function getAliases()
    {
        return [];
    }

    /**
     * {@inheritdoc}
     */
    public static function getDependencies()
    {
        return [];
    }
}

Here we have created a category attribute of type image using data patch. After adding this file to your module run the setup upgrade command.

To add that attribute in category form, add category_form.xml file under app/code/Codextblog/Demo/view/adminthtml/ui_component directory. Add below code in it.

<?xml version="1.0" ?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <fieldset name="general">
        <field name="icon">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="required" xsi:type="boolean">false</item>
                    <item name="validation" xsi:type="array">
                        <item name="required-entry" xsi:type="boolean">false</item>
                    </item>
                    <item name="sortOrder" xsi:type="number">333</item>
                    <item name="dataType" xsi:type="string">string</item>
                    <item name="formElement" xsi:type="string">fileUploader</item>
                    <item name="label" translate="true" xsi:type="string">Icon</item>
                    <item name="uploaderConfig" xsi:type="array">
                        <item name="url" path="catalog/category_image/upload" xsi:type="url"/>
                    </item>
                    <item name="elementTmpl" xsi:type="string">ui/form/element/uploader/uploader</item>
                    <item name="previewTmpl" xsi:type="string">Magento_Catalog/image-preview</item>
                </item>
            </argument>
        </field>
    </fieldset>
</form>
