Customer custom attribute with checkbox input throws exception on admin save

[dnadle]

I created an InstallData class to add two custom attributes to the Customer. One has input type 'text' and the other has input type 'checkbox'. The code to create the checkbox type is listed below.

        $customerSetup->addAttribute(Customer::ENTITY, 'customer_approved', [
            'type' => 'int',
            'label' => 'Customer Approved',
            'input' => 'checkbox',
            'required' => false,
            'visible' => true,
            'user_defined' => true,
            'sort_order' => 1001,
            'position' => 1001,
            'system' => 0,
        ]);
        
        $attribute = $customerSetup->getEavConfig()->getAttribute(Customer::ENTITY, 'customer_approved')
        ->addData([
            'attribute_set_id' => $attributeSetId,
            'attribute_group_id' => $attributeGroupId,
            'used_in_forms' => ['adminhtml_customer'],
        ]);
        
        $attribute->save();

The attribute displays a checkbox properly on the admin customer edit page, but saving the customer does not work and in debug there is an exception and stack trace that begins:

Class Magento\Customer\Model\Metadata\Form\Checkbox does not exist
#0 /vagrant/html/vendor/magento/framework/Code/Reader/ClassReader.php(19): ReflectionClass->__construct('Magento\\Custome...')

If I change the input type to 'text' and enter a value like 1 or 0 the save works.

Is 'checkbox' the wrong type to use for input? Is 'int' the wrong type to use for a boolean? Or is this a Magento bug?

Hi,

you should use 

'input' => 'boolean',

[dnadle]

When I tried setting frontend_input to 'boolean', the int value 1 was rendered as a checked box. I was able to clear the checkbox and save successfully. However, when I checked the checkbox again and saved, the save appeared to complete without errors, but the value was not updated. So there is still a bug, even with input -> 'boolean'.

I tried this with 2.0.6.

You can use "Catalog Input Type for Store Owner" = "Yes/No" .

This worked for me. Thanks

Here is my code

$eavSetup->addAttribute(
            Product::ENTITY,
            'free_shipping',
            [
                'group' => 'Product Details',
                'type' => 'int',
                'backend' => '',
                'frontend' => '',
                'label' => 'Free Shipping',
                'note' => 'Are we offering free shipping on this product?',
                'input' => 'boolean',
                'class' => '',
                'source' => '',
                'global' => ScopedAttributeInterface::SCOPE_GLOBAL,
                'visible' => true,
                'required' => false,
                'user_defined' => true,
                'default' => '0',
                'searchable' => true,
                'filterable' => true,
                'comparable' => true,
                'visible_on_front' => true,
                'used_in_product_listing' => true,
                'unique' => false,
                'apply_to' => '',
                'sort_order' => 11
            ]
        );

Hi @dnadle @jayashree_n1

Please check below code for select multiple option value. I hope it is helpful for you

$customerSetup->addAttribute(\Magento\Customer\Model\Customer::ENTITY, 'customer_approved', [
                'type' => 'varchar',
                'label' => 'Customer Approved',
                'input' => 'multiselect',
                'source' => 'Yourcompany\Customer\Model\Customer\Attribute\Source\CustomerApproved',
                'required' => false,
                'visible' => true,
                'position' => 333,
                'system' => false,
                'backend' => 'Magento\Eav\Model\Entity\Attribute\Backend\ArrayBackend'
            ]);
