我正在尝试覆盖Magento的目录搜索功能，以便它使用"AND"而不是"OR"进行搜索。
执行此操作的"正确"方法，即更新证明，是创建我自己的模块。这就是我所做的。不幸的是，这不起作用。未调用更新的方法。
这是配置文件部分：
<global>
<models>
<catalogsearch>
<rewrite>
<fulltext>MyNameSpace_MyModule_Model_CatalogSearch_Fulltext</fulltext>
</rewrite>
</catalogsearch>
</models>
</global>
我尝试覆盖的方法Mage_CatalogSearch_Model_Fulltext，我实际上正在做一个"扩展" - 例如，
class MyNameSpace_MyModule_Model_CatalogSearch_Fulltext extends Mage_CatalogSearch_Model_Fulltext
{
public function prepareResult($object, $queryText, $query)
{
die("It works...");
}
}
我在某处读到，如果您实际尝试覆盖的类从未使用特定的类"creator"方法调用，那么进行这种"覆盖"是没有意义的？如果这是真的，这可以解释为什么我的新类方法从未被使用过？
那么在这种情况下，如何覆盖此方法？我在这里做正确的事情吗？
我已成功覆盖相同的功能，查看代码：等->模块：LevoSoft_CatalogSearch.xml

public function prepareResult($object, $queryText, $query)
{
//var_dump("hasaannnnnnnn");exit;
$adapter = $this->_getWriteAdapter();
if (!$query->getIsProcessed()) {
$searchType = $object->getSearchType($query->getStoreId());
$preparedTerms = Mage::getResourceHelper('catalogsearch')
->prepareTerms($queryText, $query->getMaxQueryWords());
$bind = array();
$like = array();
$likeCond = '';

$words = Mage::helper('core/string')->splitWords($queryText, true, $query->getMaxQueryWords());
foreach ($words as $word) {
$like[] = $helper->getCILike('s.data_index', $word, array('position' => 'any'));
}
if ($like) {
$likeCond = '(' . join(' AND ', $like) . ')';
}
}
$mainTableAlias = 's';
$fields = array(
'query_id' => new Zend_Db_Expr($query->getId()),
'product_id',
);
$select = $adapter->select()
->from(array($mainTableAlias => $this->getMainTable()), $fields)
->joinInner(array('e' => $this->getTable('catalog/product')),

if ($searchType == Mage_CatalogSearch_Model_Fulltext::SEARCH_TYPE_FULLTEXT

) {
$bind[':query'] = implode(' ', $preparedTerms[0]);
$where = Mage::getResourceHelper('catalogsearch')
->chooseFulltext($this->getMainTable(), $mainTableAlias, $select);
}
if ($likeCond != '' && $searchType == Mage_CatalogSearch_Model_Fulltext::SEARCH_TYPE_COMBINE) {
$where .= ($where ? ' OR ' : '') . $likeCond;
} elseif ($likeCond != '' && $searchType == Mage_CatalogSearch_Model_Fulltext::SEARCH_TYPE_LIKE) {
$select->columns(array('relevance' => new Zend_Db_Expr(0)));
$where = $likeCond;
}
if ($where != '') {
$select->where($where);
}
$sql = $adapter->insertFromSelect($select,
$this->getTable('catalogsearch/result'),
array(),
Varien_Db_Adapter_Interface::INSERT_ON_DUPLICATE);
$adapter->query($sql, $bind);
$query->setIsProcessed(1);
}
return $this;
}
}您的配置.xml应该如下所示。
<global>
<models>
<catalogsearch>
<rewrite>
<catalogsearch_fulltext>MyNameSpace_MyModule_Model_CatalogSearch_Fulltext</catalogsearch_fulltext>
</rewrite>
</catalogsearch>
</models>
</global>
您的模型类应如下所示。
class MyNameSpace_MyModule_Model_CatalogSearch_Fulltext extends Mage_CatalogSearch_Model_Fulltext
{
// you should put default declaration of the function here.
// inside the function change the development as you want.
public function prepareResult($query = null)
{
die('It works...');
}
}
正如 Ashley 所指出的，你必须尊重你正在覆盖的方法的声明。
像这样工作的一些：
class MyNameSpace_MyModule_Model_CatalogSearch_Fulltext extends Mage_CatalogSearch_Model_Fulltext
{
public function prepareResult($query = null, $object = null, $queryText = null)
{
die('It works...');
}
}
