yii自定义rules,参数传递

Jun 06, 2016 pm 08:14 PM
php php framework yii yii2

<code>    return [
        [['cat_name','unit','pid','sort','is_show','price_area'], 'required',],
        [['pid', 'sort', 'is_show', 'price_area'], 'integer'],
        [['cat_name'], 'string', 'max' => 30],
        [['unit'], 'string', 'max' => 10],
        [['des'], 'string', 'max' => 100],
         [['cat_name'], 'checkCategoryName' ,  'params' => [ 'pid' => '1',  'catgoryname'  => 'cat_name'  ]  ], //验证分类名是否合法 (同一级别下 分类名不能重复)
    ];</code>
Copy after login
Copy after login

最后一条规则,我想把pid和 cat_name作为参数传递到 自定义的checkCategoryName($attribute, $params)中去,
但是好像只可以传递常量例如pid=1,但是为什么我传cat_name变量不行?

inline validator的话可以在方法中直接访问即可:

<code>function checkCategoryName($attribute, $params) {
    $pid = $this->pid;
}
</code>
