TP5.1 用validate的__construct来偷懒

表单太长，字段太多，差点验证写哭，那么，懒人拯救世界。

$rule = [
    'name'  => 'require|max:25',
    'age'   => 'number|between:1,120',
    'email' => 'email',
];

$field = [
    'name'  => '名称',
    'age'   => '年龄',
    'email' => '邮箱',	
];

对应的格式 

源码的

__construct

 public function __construct(array $rules = [], array $message = [], array $field = [])
    {
        $this->rule    = $rules + $this->rule;
        $this->message = array_merge($this->message, $message);
        $this->field   = array_merge($this->field, $field);
    }

其实大部分都是require，没那么多讲究，那么

我就把数据库的字段名和备注给提取出来

public function Rules($table){
        $str=sprintf("SELECT COLUMN_NAME,column_comment FROM INFORMATION_SCHEMA.Columns WHERE table_name='%s' AND table_schema='guanwang'",$table);
        $data=Db::query($str);
        $rule=[];
        $field=[];
        foreach ($data as $key=>$value){
            $field[$key]=$value['COLUMN_NAME'];
            $comment[$key]=$value['column_comment'];
        }
        unset($field[0]);
        unset($comment[0]);
        $res=array_combine($field,$comment);
        return $res;
    }

$comment是备注，用来填充$field。

然后完整代码
