我想過濾一個eZPublish提取。從多個對象ID過濾
我有一個有對象關係屬性的類。我的過濾器允許獲取由對象關係屬性過濾的此類的對象。
我已經開始使用增強對象關係篩選擴展（http://projects.ez.no/index.php/enhanced_object_relation_filter），但是這個只適用於「AND」條件，我想要「或」。
我可以編輯該文件以添加「OR」的邏輯，這是我得到了什麼：
<?php
class EORExtendedFilter
{
function CreateSqlParts($params)
{
$db =& eZDB::instance();
$tables = array();
$joins = array();
// foreach filtered attribute, we add a join the relation table and filter
// on the attribute ID + object ID
foreach($params as $param)
{
if (!is_array($param))
continue;
if (!is_numeric($param[0]))
{
$classAttributeId = eZContentObjectTreeNode::classAttributeIDByIdentifier($param[0]);
}
else
{
$classAttributeId = $param[0];
}
// multiple objects ids
if (is_array($param[1]))
{
foreach($param[1] as $objectId)
{
$join = array(); // 'OR' logic
if (is_numeric($objectId))
{
$tableName = 'eor_link_' . $objectId;
$tables[] = 'ezcontentobject_link ' . $tableName;
$join[] = $tableName . '.from_contentobject_id = ezcontentobject.id';
$join[] = $tableName . '.from_contentobject_version = ezcontentobject.current_version';
$join[] = $tableName . '.contentclassattribute_id = ' . $classAttributeId;
$join[] = $tableName . '.to_contentobject_id = ' . $objectId;
}
// 'OR' logic
$joins[] = $join;
}
}
// single object id
else
{
$objectId = $param[1];
$tableName = 'eor_link_' . $objectId;
$tables[] = 'ezcontentobject_link ' . $tableName;
$joins[] = $tableName . '.from_contentobject_id = ezcontentobject.id';
$joins[] = $tableName . '.from_contentobject_version = ezcontentobject.current_version';
$joins[] = $tableName . '.contentclassattribute_id = ' . $classAttributeId;
$joins[] = $tableName . '.to_contentobject_id = ' . $objectId;
}
}
if (!count($tables) or !count($joins))
{
$tables = $joins = '';
}
else
{
$tables = "\n, " . implode("\n, ", $tables);
// 'OR' logic
if (is_array($param[1]))
{
$andClauses = array();
foreach ($joins as $attr)
{
$andClauses[] = implode(" AND\n ", $attr);
}
$joins = implode(" OR\n ", $andClauses) . " AND\n ";
}
else
{
$joins = implode(" AND\n ", $joins) . " AND\n ";
}
}
return array('tables' => $tables, 'joins' => $joins);
}
}
此擴展屬性過濾器生成字符串：
eor_link_126.from_contentobject_id = ezcontentobject。 id AND eor_link_126.from_contentobject_version = ezcontentobject.current_version AND eor_link_126.contentclassattribute_id = 537 AND eor_link_126.to_contentobject_id = 126 OR（eor_link_127.from_contentobject_id = ezcontentobject.id AND eor_link_127.from_contentobject_version = ezcontentobject.current_version AND eor_link_127.contentclassattribute_id = 537 AND eor_link_127.to_contentobject_id = 127 AND
我知道它遺漏了一些括號，所以我編輯了字符串以直接在phpMyAdmin中測試它。這是查詢：

事情是，當我執行上面的查詢，沒有什麼會返回，因爲查詢永遠不會停止。 CPU達到100％，我不得不重新啓動mysql，這意味着它不是一個語法問題。
下面是該查詢的解釋：
如果任何人有這個任何線索，將是非常有益的。
