Magento 2 - Get Attribute Set by ID?

Question

Is there a way from a phtml file to get the attributes of an attribute set given the set id?

Answer 1

You will have to create a module for this.

So basically, you first need to find out which block renders your phtml file.

Once you've found out, you need to create app/code/Vendor/Module/etc/frontend/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\<Module>\Block\<Path>\<To>\<Block>"
                type="Vendor\Module\Block\<Path>\<To>\<Block>"/>
</config>

In this file you need to replace Magento\<Module>\Block\<Path>\<To>\<Block> with the path to the block rendering the template. Don't forget to replace <Path>\<To>\<Block> in the type attribute too.

Then in app/code/Vendor/Module/Block/<Path>/<To>/<Block> :

<?php
namespace Vendor\Module\Block\<Path>/<To>;

class <Block> extends \Magento\<Module>\Block\<Path>\<To>\<Block>
{

    protected $_productAttributeManagementInterface;

    public __construct(
        ...
        \Magento\Catalog\Api\ProductAttributeManagementInterface $productAttributeManagementInterface
        ...
    ) {
        ...
        $this->_productAttributeManagementInterface= $productAttributeManagementInterface;
        ...
    }

    public function getAttributes($id)
    {
        $attributes = $this->_productAttributeManagementInterface->getAttributes($id);
        return $attributes ;
    }
}

Please note that you will have to adapt the constructor with the original block constructor.

Don't forget the usual app/code/Vendor/Module/etc/module.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Vendor_Module" setup_version="0.0.1" />
</config>

As well as the app/code/Vendor/Module/registration.php

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'Vendor_Module',
    __DIR__
);

Finally run the following commands:

php bin/magento module:enable Vendor_Module
php bin/magento setup:upgrade

And now you should be able to call the following in your template:

$attributes = $block->getAttributes($attributeSetId);
