标签:desc sort array 一行代码 where date phpstorm top post
看上图 其中数组 UniversityPostSearch 是通过前端表单传过来的数据,而我只想验证 这个表单数据是不是合法 应该这样写
$this->load($param,‘UniversityPostSearch‘);
参数 $param 是YII::$app->requist->get() 传过来的所有值 就是上图的 array(3){[id] = .......}
参数 ‘UniversityPostSearch‘ 是需要验证的表单
这个加载的好处就是 不用再一步一步的复制 其作用等价于
$this->title = (string)$param[‘UniversityPostSearch‘][‘title‘];
$this->create_time_start = (string)$param[‘UniversityPostSearch‘][‘create_time_start‘];
$this->create_time_end = (string)$param[‘UniversityPostSearch‘][‘create_time_end‘];
$this->status = (int)$param[‘UniversityPostSearch‘][‘status‘];
....
好多行逐一赋值的代码 浓缩为 一行代码 也即
$this->load($param,‘UniversityPostSearch‘);
底层 load() 函数的代码如下图 这就是为什么要传第二个参数的原因
接下来就是rule规则验证的问题
为什么create_time_start 和 create_time_end 需要单独定义一下,而 ‘is_top‘, ‘title‘ 不用定义,直接写在 rule()方法 里面了 ??
因为 create_time_start create_time_end 并不是数据库已经存在的字段 如果不写的话 $this->create_time_start 就会报错 说Undifiend create_time_start ..
而 ‘is_top‘ , ‘title‘ 是数据库里面的字段,不用定义,就可以 引用 $this->is_top,但是必须要写在rules规则里面,不写错,值为null,赋值就不起作用了。
全部代码如下
