如何解决SQLSTATE[42S22]：未找到列：1054 yii2 中“where 子句”中的未知列“guidian.id”
我是 Yii2 PHP 框架的新手，我有学生表格来获取学生详细信息和 guardian id_no，提交时我收到此错误 sqlSTATE[42S22]: Column not found: 1054 UnkNown column 'guidian.id' in 'where clause' The sql being executed was: SELECT EXISTS(SELECT * FROM guidian WHERE guidian.id='123') 学生表有 guidian_id 作为 {{ 1}} 在 foreign key 表上引用 id_no，我对说 guidian 的错误感到困惑，而实际上我没有在 guidian.id 中指定 id 作为列表（我在 guidian 表中没有 guidian 列）。注意：我理解错别字 id 而不是 guidian
这是guardian

guidian.PHP解决方法
抱歉，我已经解决了，规则函数中有一个 Id 关联了两个表
