如何在rules（）方法中获得验证？

Question

Just for explanation,here is the table

create table test(mark int,item1 varchar(128),item2 varchar(128));

If mark==1 then item1 requires a value ,if mark==2 then item2 requires a value

In rules() method,how can I get this rule?

Answer 1

Create your custom validating function in the model, smth. like this:

public function requiredMark($attributes,$params)
{
    if ($this->mark == 1 && $this->item1==null)
        $this->addError('item1','Item 1 is required');
    elseif ($this->mark == 2 && $this->item2==null)
        $this->addError('item2','Item 2 is required');
}

Or u was asking about something other?

Answer 2

You'll need to extend the validate() method to do this, and add errors manually. I always get back to this document for validator options (it might be useful later on)
