Magento ver.: 2.2.2

I have created custom image attribute. This is displaying perfectly. But when I upload an image and save product, it's not saving. When I have debugged my code, I have found an issue. My image attribute value display null value every time in my model file(MagetestTestModelAttributeProductImage).

Here is my code.

app/code/Magetest/Test/Setup/InstallData.php

    <?php

I believe you are missing the upload action. Check with below steps if anything you have missed.

Step:-1

Create a InstallData.php file on location vendorModuleSetup

<?php

    namespace VendorModuleSetup;



    use MagentoEavSetupEavSetup;

    use MagentoEavSetupEavSetupFactory;

    use MagentoFrameworkSetupInstallDataInterface;

    use MagentoFrameworkSetupModuleContextInterface;

    use MagentoFrameworkSetupModuleDataSetupInterface;

    use MagentoEavModelEntityAttributeScopedAttributeInterface;



    /**

     * @codeCoverageIgnore

     */

    class InstallData implements InstallDataInterface

    {

        /**

         * EAV setup factory.

         *

         * @var EavSetupFactory

         */

        private $_eavSetupFactory;

        protected $categorySetupFactory;



        /**

         * Init.

         *

         * @param EavSetupFactory $eavSetupFactory

         */

        public function __construct(EavSetupFactory $eavSetupFactory, MagentoCatalogSetupCategorySetupFactory $categorySetupFactory)

        {

            $this->_eavSetupFactory = $eavSetupFactory;

            $this->categorySetupFactory = $categorySetupFactory;

        }



        /**

         * {@inheritdoc}

         *

         * @SuppressWarnings(PHPMD.ExcessiveMethodLength)

         */

        public function install(

            ModuleDataSetupInterface $setup,

            ModuleContextInterface $context

        ) {

            /** @var EavSetup $eavSetup */

            $eavSetup = $this->_eavSetupFactory->create(['setup' => $setup]);

            $setup = $this->categorySetupFactory->create(['setup' => $setup]);         

            $setup->addAttribute(

                MagentoCatalogModelProduct::ENTITY, 'custom_image', [

                    'type' => 'varchar',

                    'label' => 'Custom Image',

                    'input' => 'image',

                    'backend' => 'MagentoCatalogModelProductAttributeBackendImage',

                    'required' => false,

                    'sort_order' => 9,

                    'global' => MagentoEavModelEntityAttributeScopedAttributeInterface::SCOPE_STORE,

                    'group' => 'General Information',

                ]

            );

        }

    }

Step:-2

Create a product_form.xml file on location PackageCustom_Moduleviewadminhtmlui_component

<?xml version="1.0" encoding="UTF-8"?>

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

      xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">

    <fieldset name="content">

        <field name="custom_image">

            <argument name="data" xsi:type="array">

                <item name="config" xsi:type="array">

                    <item name="dataType" xsi:type="string">string</item>

                    <item name="source" xsi:type="string">category</item>

                    <item name="label" xsi:type="string" translate="true">Custom Image</item>

                    <item name="visible" xsi:type="boolean">true</item>

                    <item name="formElement" xsi:type="string">fileUploader</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 name="required" xsi:type="boolean">false</item>

                    <item name="sortOrder" xsi:type="number">40</item>

                    <item name="uploaderConfig" xsi:type="array">

                        <item name="url" xsi:type="url" path="module/product_image/upload"/>

                    </item>

                </item>

            </argument>

        </field>

    </fieldset>

</form>

Step:-3

Add below code in Vendor/Module/etc/di.xml

<type name="VendorModuleControllerAdminhtmlProductImageUpload">

    <arguments>

        <argument name="imageUploader" xsi:type="object">MagentoCatalogProductImageUpload</argument>

    </arguments>

</type>

<virtualType name="MagentoCatalogProductImageUpload" type="MagentoCatalogModelImageUploader">

    <arguments>

        <argument name="baseTmpPath" xsi:type="string">catalog/tmp/product</argument>

        <argument name="basePath" xsi:type="string">catalog/product</argument>

        <argument name="allowedExtensions" xsi:type="array">

            <item name="jpg" xsi:type="string">jpg</item>

            <item name="jpeg" xsi:type="string">jpeg</item>

            <item name="gif" xsi:type="string">gif</item>

            <item name="png" xsi:type="string">png</item>

        </argument>

    </arguments>

</virtualType>

Step:-4

Create Upload.php file on location Vendor/Module/Controller/Adminhtml/Product/Image

<?php

namespace VendorModuleControllerAdminhtmlProductImage;



use MagentoFrameworkControllerResultFactory;



/**

class Upload extends MagentoBackendAppAction

    protected $logger;



    /**

     * Upload constructor.

     *

    public function __construct(

    public function execute()

    {

        try {

            $result = $this->imageUploader->saveFileToTmpDir('custom_image');

            $result['cookie'] = [

    }

}

Try if this helps you!
