我是 Yii 的新手,我正在尝试以“正确”的方式完成我的初始项目。我创建了一个 CFormModel 类,它需要三个字段来查询一些数据,一个 CForm 配置来构造表单,以及一个 CController 来将它绑定在一起(所有内容都在下面给出)。
数据请求需要一个帐户,这可能来自几个不同的地方。我认为检索它应该在控制器中。但是,我不知道如何从控制器将其放入表单的隐藏“帐户”字段中,以便在提交后将其分配给 CFormModel 的参数。更一般地说,我知道如何从 CController 传递给查看脚本,但不知道如何传递给 CForm。注册表 ( Yii::app()->params[]
) 是我最好的选择吗?
我想我可以把它从表单(和必填字段)中删除,然后等待在提交操作(actionSummaries
)中填充它。这会破坏 CForm 的意图吗?有最佳实践吗?即使采用这个解决方案,有人可以解决第一个问题,以防它再次出现吗?
欢迎任何其他温和的批评。
