Magento 2 Created a custom product Attribute of drop down yes or no

Question

I have created a custom attribute in magento 2 for product using a source Magento\Eav\Model\Entity\Attribute\Source\Boolean

Here is the code

     if(!$eavSetup->getAttributeId(\Magento\Catalog\Model\Product::ENTITY, 'purchase_unit')) {
        $eavSetup->addAttribute(
            Product::ENTITY,
            'purchase_unit',
            [
                'group' => 'Rocket',
                'type' => 'int',/* Data type in which formate your value save in database*/
                'backend' => '',
                'frontend' => '',
                'label' => 'Purchase Unit', /* lablel of your attribute*/
                'input' => 'select',
                'class' => '',
                'source' => 'Magento\Eav\Model\Entity\Attribute\Source\Boolean',
                'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
                /*Scope of your attribute */
                'visible' => true,
                'required' => false,
                'user_defined' => false,
                'default' => '0',
                'searchable' => false,
                'filterable' => false,
                'comparable' => false,
                'visible_on_front' => false,
                'used_in_product_listing' => false,
                'unique' => false
            ]
        );
    }

The attribute is getting created and also displays in product page. The issue is it displays YES as default value which is 1. How to solve this problem?

Answer 1

Since you just have options Yes/No. Replacing 'input' => 'select' with 'input' => 'boolean' will solve your problem.

Hope it was helpful.
