Steps to Add Custom Field and Save Value in Product Attribute Add Form in Magento 2:

Step 1: First we need to create a “di.xml” file inside the etc folder

app\code\Vendor\Extension\etc\adminhtml

Now, add the code as follows

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Catalog\Block\Adminhtml\Product\Attribute\Edit\Tab\Front">
        <plugin name="extension_attribute_edit_form" type="Vendor\Extension\Plugin\Block\Adminhtml\Product\Attribute\Edit\Tab\Front" sortOrder="1"/>
    </type>
</config>

<?xml version="1.0"?>

</type>

</config>

Step 2: In the next step, we will create the “Front.php” file inside the Plugin folder

app\code\Vendor\Extension\Plugin\Block\Adminhtml\Product\Attribute\Edit\Tab

Then append the below-mentioned code snippet

<?php
namespace Vendor\Extension\Plugin\Block\Adminhtml\Product\Attribute\Edit\Tab;

class Front
{

    protected $custom;

    public function __construct(
        \Magento\Config\Model\Config\Source\Yesno $custom
    ) {
        $this->custom = $custom;
    }

    public function aroundGetFormHtml(
        \Magento\Catalog\Block\Adminhtml\Product\Attribute\Edit\Tab\Front $subject,
        \Closure $proceed
    )
    {

        $customSource = $this->custom->toOptionArray();
        $form = $subject->getForm();
        $fieldset = $form->getElement('front_fieldset');
        $fieldset->addField(
            'used_in_custom',
            'select',
            [
                'name' => 'used_in_custom',
                'label' => __('Used in Custom'),
                'title' => __('Used in Custom'),
                'values' => $customSource,
            ]
        );
        return $proceed();
    }
}

<?php

namespace Vendor\Extension\Plugin\Block\Adminhtml\Product\Attribute\Edit\Tab;

class Front

{

protected $custom;

public function __construct(

\Magento\Config\Model\Config\Source\Yesno $custom

) {

$this->custom = $custom;

}

public function aroundGetFormHtml(

\Magento\Catalog\Block\Adminhtml\Product\Attribute\Edit\Tab\Front $subject,

\Closure $proceed

)

{

$customSource = $this->custom->toOptionArray();

$form = $subject->getForm();

$fieldset = $form->getElement('front_fieldset');

$fieldset->addField(

'used_in_custom',

'select',

[

'name' => 'used_in_custom',

'label' => __('Used in Custom'),

'title' => __('Used in Custom'),

'values' => $customSource,

]

);

return $proceed();

}

Step 3: Then we will create the “db_schema.xml” file inside the etc folder

app\code\Vendor\Extension\etc

Finally, add the following code

<schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd">
    <table name="catalog_eav_attribute" resource="default" engine="innodb" comment="Catalog EAV Attribute Table">
        <column xsi:type="smallint" name="used_in_custom" unsigned="true" nullable="false"
                identity="false" default="0" comment="Custom forms"/>
   </table>
</schema>

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

xsi:noNamespaceSchemaLocation="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd">

<column xsi:type="smallint" name="used_in_custom" unsigned="true" nullable="false"

identity="false" default="0" comment="Custom forms"/>

</table>
