gridview - yii2 select2 gridview过滤器搜索模型

Question

我正在尝试使用 select2 过滤 yii2 gridview

在 ModelSearch 我有

 ->andFilterWhere(['like', 't_persons.functions', $this->functions ])

不幸的是，字符串 (1) 也匹配 10 和 11

如何过滤逗号分隔字段中的整数值？

Answer 1

To match a single value in a comma-separated field use FIND_IN_SET, e.g.:

SELECT * FROM t_persons WHERE FIND_IN_SET('3', functions);

To integrate that into Yii2, you might (if I've understood your nomenclature correctly) use:

->andFilterWhere(new Expression('FIND_IN_SET(:function_to_find, functions)'))->addParams([':function_to_find' => $this->functions])->asArray()->all();

Answer 2

如果您有一串逗号分隔值，我会尝试：

->andFilterWhere('t_persons.functions in ('.$this->functions.')')
