Magento，sql，setup的方式添加一个select属性，add attribute selet by module sql

1.新建一个模块Resource里面这么定义：

<resources>
<wailian_setup>
<setup>
<module>Lon_Wailian</module>
<class>Mage_Catalog_Model_Resource_Setup</class>
</setup>
<connection>
<use>core_setup</use>
</connection>
</wailian_setup>
</resources>

注意：在<setup>里面<class>Mage_Catalog_Model_Resource_Setup</class>，这个一定要填写正确Mage_Catalog_Model_Resource_Setup2.数据库文件

<?php

$installer = $this;
$installer->startSetup();

//属性的Attribute Code，只能用字母和下划线，中间可以加入数字
$attribute_name = 'ccc';
//属性集中的group，和general等一个东西，是后台产品详细页面左侧的标签
$AttributeGroup = "sss";

if(! ($this instanceof Mage_Catalog_Model_Resource_Setup) )
{
throw new Exception("Resource Class needs to inherit from " .
"Mage_Catalog_Model_Resource_Setup for this to work");
}
//属性定义
$attr = array (
'attribute_model' => NULL,
'backend' => '',
'type' => 'int',
'table' => '',
'frontend' => '',
'input' => 'select',  //Catalog Input Type for Store Owner
'label' => 'bbb',  //label
'frontend_class' => '',
'source' => '',
'required' => '0',  //Values Required
'user_defined' => '1',
'default' => '',
'unique' => '0',
'note' => '',
'input_renderer' => NULL,
'global' => '1',  //Scope
'visible' => '1',
'searchable' => '1', //Use in Quick Search
'filterable' => '1', //Use In Layered Navigation
'comparable' => '1', //Comparable on Front-end
'visible_on_front' => '0',
'is_html_allowed_on_front' => '0',  //Allow HTML Tags on Frontend
'is_used_for_price_rules' => '1',
'filterable_in_search' => '1', //Use In Search Results Layered Navigation
'used_in_product_listing' => '0', //Used in Product Listing
'used_for_sort_by' => '0', //Used for Sorting in Product Listing
'is_configurable' => '1', //Use To Create Configurable Product
'apply_to' => 'simple', //Apply To *
'visible_in_advanced_search' => '1', //Use in Advanced Search
'position' => '1', //Position
'wysiwyg_enabled' => '0',
'used_for_promo_rules' => '1',
'option' =>
array (
'values' =>
array (
0 => 'Green',
1 => 'Silver',
2 => 'Black',
3 => 'Blue',
4 => 'Red',
5 => 'Pink',
6 => 'Magneta',
7 => 'Brown',
8 => 'White',
9 => 'Gray',
),
),
);
//新建属性
$this->addAttribute('catalog_product',$attribute_name,$attr);

//下面的部分为把新建的属性加入属性集
//得到属性的id
$attributeId = $installer->getAttributeId(
'catalog_product',
$attribute_name
);
//得到属性集的id
$defaultSetId = $installer->getAttributeSetId('catalog_product', 'default');
//在属性集里面新建group，也就是打开产品后，左边的标签，譬如general
$installer->addAttributeGroup(
'catalog_product',
$defaultSetId,
$AttributeGroup
);

//得到新建的group的id
$groupId = $installer->getAttributeGroup(
'catalog_product',
$defaultSetId,
$AttributeGroup,
'attribute_group_id'
);

//把属性加入到属性集，并在上面新建的group中
if ($attributeId > 0) {
$installer->addAttributeToSet(
'catalog_product',
$defaultSetId,
$groupId,
$attributeId
);
}

//OK新建一个select属性到这里就完成了

$installer->endSetup();

清空缓存，运行，就会建立起来属性了
