How to create custom product attribute and add it to product view page programmatically

 

Before starting this session, I recommend if you haven’t created any module in Magento 2 earlier then refer to the Hello World Module, to understand the request flow of Magento 2 refer to the  Magento 2.0 request Flow and to understand the Magento 2 architecture refers to the Magento 2.0 Architecture.

 

Now, I hope you have the basic knowledge of Magento 2, so let’s begin with today’s task.

 

We have divided this blog into two sections, first we will see how to create a custom product attribute programmatically then we will see how can we show that attribute on product view page without overwriting any core file, so let’s start the quest.

 

 

1. Create a custom product attribute:

First, create an empty module then, create an app/code/Ced/HelloWorld/Setup/InstallData.php  file in your module then, use the below code into it,

 

<?php 

namespace Ced\HelloWorld\Setup;

use Magento\Framework\Setup\ModuleContextInterface;

use Magento\Framework\Setup\ModuleDataSetupInterface;

use Magento\Framework\Setup\InstallDataInterface;

use Magento\Eav\Setup\EavSetupFactory;




class InstallData implements InstallDataInterface

{

  private $eavSetupFactory;




  public function __construct(EavSetupFactory $eavSetupFactory) {

      $this->eavSetupFactory = $eavSetupFactory;

  }




  public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)

  {




      /**** Attribute names and there data*****/

       /* [atr-Code, atr-group, atr-type, label, input, required,default] */




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

       $attributes = [

          ['name' => 'custom_attribute',

              'group' => 'Product Details',

              'type' => 'text',

              'label' => 'Custom Attribute',

              'class' => 'validate-number',

              'input' => 'text',

              'is_used_in_grid' => 1,

              'required' => true,

              'sort_order' => 20],

          /*can duplicate the array for more attributes*/

       ];

      foreach ($attributes as $key => $value) {

          $eavSetup->addAttribute(

              \Magento\Catalog\Model\Product::ENTITY,

              $value['name'],   /* Custom Attribute Code */

               [

                  'group' => $value['group'],/* Group name in which you want to display your custom attribute */

                  'type' => $value['type'],/* Data type in which formate your value save in database*/

                  'backend' => (isset($value['backend'])) ? $value['backend'] : '',

                  'frontend' => '',

                  'label' => $value['label'], /* lablel of your attribute*/

                  'input' => $value['input'],

                  'frontend_class' => ((isset($value['class'])) ? $value['class'] : ''),

                  'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,

                  'visible' => (isset($value['visible'])) ? $value['visible'] : true,

                  'required' => $value['required'],

                  'source' => (isset($value['source'])) ? $value['source'] : '',

                  'option' => (isset($value['option'])) ? $value['option'] : '',

                  'user_defined' => (isset($value['user_defined'])) ? $value['user_defined'] : false,

                  'sort_order' => 50,

                  'default' => (isset($value['default'])) ? $value['default'] : '',

                  'note' => (isset($value['note'])) ? $value['note'] : '',

                  'searchable' => true,

                  'filterable' => true,

                  'comparable' => true,

                  'visible_on_front' => false,

                  'used_in_product_listing' => true,

                  'unique' => false,

                  'is_used_in_grid' => (isset($value['is_used_in_grid'])) ? $value['is_used_in_grid'] : 0,

              ]

          );

      }
  }
}

 

After adding the above code in InstallData.php, run the commands given below:

 

php bin/magento setup:upgrade

php bin/magento setup:di:compile

php bin/magento setup:static-content:deploy 

php bin/magento cache:clean

php bin/magento cache:flush

 

 

After running commands you will see that your custom attribute will be created.

 

 

2. Show the custom product attribute on the product view page:

 

To do this, create a layout file  Ced/HelloWorld/view/frontend/layout/catalog_product_view.xml  

 

<?xml version="1.0"?>

    <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
           xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">

           <body>

            <referenceContainer name="product.info.main">

                <block class="Magento\Catalog\Block\Product\View\Description" name="product.info.custom_attribute"

                  template="Magento_Catalog::product/view/attribute.phtml" after="product.info.sku">

                    <arguments>

                        <argument name="at_call" xsi:type="string">getCustomAttribute</argument>

                        <argument name="at_code" xsi:type="string">custom_attribute</argument>

                        <argument name="css_class" xsi:type="string">custom_attribute</argument>

                        <argument name="at_label" xsi:type="string">default</argument>

                        <argument name="add_attribute" xsi:type="string">itemprop="custom_attribute"</argument>

                    </arguments>

                </block>

            </referenceContainer>

        </body>

</page>

 

 

Now run the below two commands for clearing cache and then reload the product page,

 

php bin/magento cache:clean

php bin/magento cache:flush

 

That’s it from our end. We hope that this blog will be helpful for you in creating a custom product attribute and you can easily add it to the product view page programmatically.
