Magento2 Add Product Attribute Not Working - attributes

Question

I have created a file setup/installdata.php:
use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
class InstallData implements InstallDataInterface
{
private $eavSetupFactory;
public function __construct(EavSetupFactory $eavSetupFactory)
{
$this->eavSetupFactory = $eavSetupFactory;
}
public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
$eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
$eavSetup->addAttribute(
\Magento\Catalog\Model\Product::ENTITY,
'name',
[
'type' => 'int',
'backend' => '',
'frontend' => '',
'label' => 'attrlabel',
'input' => 'select',
'class' => '',
'source' => 'a\b\Model\Attribute\Source\m',
'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
'visible' => true,
'required' => false,
'user_defined' => true,
'default' => '',
'searchable' => false,
'filterable' => false,
'comparable' => false,
'visible_on_front' => false,
'used_in_product_listing' => true,
'unique' => false,
'apply_to' => '',
'attribute_set' => 'Default',
]
);
}
}
Then, in etc/module.xml, I have:
<module name="Conlabz_IdentityCheck" setup_version="1.0.0" />
But I still don't see the attribute created.
I also tried the following:
In the Magento root folder, I run the following commands:
php bin/magento module:disable
php bin/magento module:enable
php bin/magento setup:upgrade
php bin/magento cache:flush
All succeed without an error, but as I said, it doesn't work.
What am I doing wrong?

Answer 1

Check your filename setup/installData.php.
"D" should be capital.
Then search table "setup_module" in your magento2 database and delete entry for "Conlabz_IdentityCheck".
Then run following command :
php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy -f

Answer 2

First, the file and folder name should be Setup/InstallData.php
In your InstallData.php file, you have to add this code at the first line:
namespace Conlabz\IdentityCheck\Setup;
Then just run the CLI commands.
However, if you still facing issues then for reference you can checkout this guide on Magento Attributes.
