Question

我在FrameSearch Model中定制了查询并使用findbysql构建了我的查询。我也在尝试自定义操作列。除了动作列之外，我的gridview看起来很好。得到错误 -

添加退出后;

请告诉我如何解决这个问题。我想从动作列按钮中获取f_name，我将传递给另一个页面以过滤网格。

Answer 1

我通常建议使用ArrayHelper::getValue。

例如：

ArrayHelper::getValue($model, 'f_name')

当$model是某个对象（Model或ActiveRecord），数组或空（=null）时，

将起作用。此外，它有默认值的第3个参数：

ArrayHelper::getValue($model, 'f_name', 'value that returned when attribute not found in $model')

试图在yii2中获取非对象的属性
