I am adding the code from that answer so you can get it from here in case the link gets broken.

Magento2 way is to use UI components and PHP Modifiers

Create 3 files:

etc/adminhtml/di.xml - dependency injection configuration for adminhtml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <virtualType name="Magento\Catalog\Ui\DataProvider\Product\Form\Modifier\Pool">
            <argument name="modifiers" xsi:type="array">
                <item name="your_module_datasheet" xsi:type="array">
                    <item name="class" xsi:type="string">Vendor\Module\Ui\DataProvider\Product\Form\Modifier\Datasheet</item>
                    <item name="sortOrder" xsi:type="number">150</item>

your_module_datasheet can be any name.

With sortOrder from 10 to 50 it didn't work for me. $meta variable in Modifier was empty.

Ui/DataProvider/Product/Form/Modifier/Datasheet.php - php modifier

namespace Vendor\Module\Ui\DataProvider\Product\Form\Modifier;

use Magento\Catalog\Model\Locator\LocatorInterface;
use Magento\Catalog\Ui\DataProvider\Product\Form\Modifier\AbstractModifier;
use Magento\Framework\Stdlib\ArrayManager;
use Magento\Framework\UrlInterface;

 * Data provider for "Datasheet" field of product page
class Datasheet extends AbstractModifier
     * @param LocatorInterface            $locator
     * @param UrlInterface                $urlBuilder
     * @param ArrayManager                $arrayManager
    public function __construct(
        LocatorInterface $locator,
        UrlInterface $urlBuilder,
        ArrayManager $arrayManager
    ) {
        $this->locator = $locator;
        $this->urlBuilder = $urlBuilder;
        $this->arrayManager = $arrayManager;

    public function modifyMeta(array $meta)
        $fieldCode = 'datasheet';
        $elementPath = $this->arrayManager->findPath($fieldCode, $meta, null, 'children');
        $containerPath = $this->arrayManager->findPath(static::CONTAINER_PREFIX . $fieldCode, $meta, null, 'children');

        if (!$elementPath) {
            return $meta;

        $meta = $this->arrayManager->merge(
                'children'  => [
                    $fieldCode => [
                        'arguments' => [
                            'data' => [
                                'config' => [
                                    'elementTmpl'   => 'Vendor_Module/grid/filters/elements/datasheet',

        return $meta;

     * {@inheritdoc}
    public function modifyData(array $data)
        return $data;

view/adminhtml/web/template/grid/filters/elements/datasheet.html - knockout js template

<!-- ko if: $parent.source.data.product[code] -->
    <!-- todo: dynamically get path to file from config or controller -->
    <a attr="href: '/pub/media/datasheet'+$parent.source.data.product[code]" text="$parent.source.data.product[code]"></a>
    <label attr="for: uid+'_delete'">
        <!-- todo: generate name -->
        <input type="checkbox" attr="name: 'product['+code + '_delete]', id: uid+'_delete', form: formId">
        <span data-bind="i18n:'Delete'"></span>
<!-- /ko -->
<input class="admin__control-file" type="file" data-bind="
    hasFocus: focused,
    attr: {
        name: inputName,
        placeholder: placeholder,
        'aria-describedby': noticeId,
        id: uid,
        disabled: disabled,
        form: formId

It is still looks dirty to me and a lot of things to improve.


I found some interesting files, which can bring you other ideas how to solve it:


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


<fileUploader class="Magento\Ui\Component\Form\Element\DataType\Media">
  • i treid but this is not working, can u tell path of "Ui/DataProvider/Product/Form/Modifier/Datasheet.php" – user1799722 Oct 14 '18 at 15:30
  • You have to create this class in your module Path would be Vendor/Module/Ui/DataProvider/Product/Form/Modifier/Datasheet.php – Dinesh Yadav Oct 15 '18 at 4:32
