Question

我创建了一个带有自定义数据属性的新产品。

$product = Mage::getModel('catalog/product');
$product->setStatus(Mage_Catalog_Model_Product_Status::STATUS_ENABLED);
$product->setVisibility(Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH);
$product->setName('name');
$product->setDescription('description');
$product->setPrice(1.24);
$product->setData('lid', 123);
$product->save

现在我想使用Mage :: getModel（＆＃39; catalog / product＆＃39;）查询此产品。

如何查询带有＆＃39;的产品？ 123？

如何查询“盖子”的产品？存在又不是空的吗？

使用addAttributeToFilter执行查询时的错误日志。

Answer 1

对于create attribute，在magento根目录中运行此脚本（可以根据需要进行编辑）

<?php  

require_once('app/Mage.php');
 Mage::app()->setCurrentStore(Mage::getModel('core/store')->load(Mage_Core_Model_App::ADMIN_STORE_ID));

$installer = new Mage_Eav_Model_Entity_Setup('core_setup');
$installer->startSetup();                   

$installer->addAttribute('catalog_product', 'lid', array(
             'label'             => 'LId',
             'type'              => 'int',
             'input'             => 'text',
             'backend'           => '',
             'frontend'          => '',
             'global'            => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
             'visible'           => true,
             'required'          => false,
             'user_defined'      => false,
             'searchable'        => false,
             'filterable'        => false,
             'comparable'        => false,
             'visible_on_front'  => true,
             'visible_in_advanced_search' => false,
             'unique'            => false
));
$installer->endSetup();

?>

现在您的属性已创建，请参阅我有created
然后设置您想要的值see

按属性过滤产品。

$product = Mage::getModel('catalog/product')
    ->getCollection()
    ->addAttributeToFilter('lid', 123);

foreach ($product as $products) { 
    echo '<pre>';
    print_r($products);
}

使用Lid Exist获取产品

$product = Mage::getModel('catalog/product')
    ->getCollection();


foreach ($product as $products) { 
    if($products->getLid()){
       echo $products->getName().'-->'.$products->getLid().'<br>';
    }
}

Answer 2

理论上，您可以过滤产品系列：

$product = Mage::getModel('catalog/product')
    ->getCollection()
    ->addAttributeToFilter('lid', 123);

foreach ($product as $products) { /** @var Mage_Catalog_Model_Product $product */
    // Product Collection Here
}

Answer 3

如果只有一个产品可以加载

$product = Mage::getModel('catalog/product')->load(123,'lid')

如果您需要加载集合

$product = Mage::getModel('catalog/product')
    ->getCollection()
    ->addAttributeToFilter('lid', 123);

在Magento中按数据属性选择产品
