我想制作搜索系统。我将搜索示例单词：“KATE”。如何在KATE中搜索多对多的表？

在输入搜索中，我写“KATE”。我必须在Doctrine中使用WHERE LIKE。这个查询必须如何看？这应该向我显示用户名为Kate的所有用户以及组Kate的所有用户。

Answer 1

您的DQL会发生以下情况......

在组kate中搜索名为kate或Users的用户，返回用户和组

FROM User u LEFT JOIN u.Groups g WHERE u.username LIKE 'KATE' OR g.name LIKE 'KATE'

所以...

$qry = Doctrine_Query::create()
  ->from('User u')
  ->leftJoin("u.Groups g")
  ->where("u.username LIKE ? OR g.name LIKE ?", array('KATE','KATE'));

如何在Doctrine中搜索多对多的关系？
