<?php
/**
 * Created By : Rohan Hapani
 */
namespace RH\CheckAttribute\Block;

class IsSwatchAttribute extends \Magento\Framework\View\Element\Template {
    /**
     * @var \Magento\Eav\Model\Config
     */
    protected $eavConfig;

    /**
     * @var \Magento\Swatches\Helper\Data
     */
    protected $swatchHelper;

    /**
     * @param \Magento\Framework\View\Element\Template\Context $context
     * @param \Magento\Eav\Model\Config                        $eavConfig
     * @param \Magento\Swatches\Helper\Data                    $swatchHelper
     * @param array                                            $data
     */
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Eav\Model\Config $eavConfig,
        \Magento\Swatches\Helper\Data $swatchHelper,
        array $data = []
    ) {
        $this->eavConfig = $eavConfig;
        $this->swatchHelper = $swatchHelper;
        parent::__construct($context, $data);
    }

    public function isSwatchAttr()
    {
        $attribute = $this->eavConfig->getAttribute('catalog_product', 'color');
        return $this->swatchHelper->isSwatchAttribute($attribute);
    }
}

Here, in isSwatchAttr() function you can see that in getAttribute() we need to set eav_entity_type in first parameter and attribute_code in second parameter.

Then, you can use this function in your phtml file like this below way :

Copy Code


echo $block->isSwatchAttr();

Its return type is Boolean (True/false). So, you will get the output as a boolean type.
