李炎恢ThinkPHP讲义ThinkPHP--自动验证[上][12]

Posted 2020-10-01

控制层IndexController

<?php
namespace Home\Controller;
use Think\Controller;
class IndexController extends Controller {

    public function index(){
        //$food = M(‘food‘);
        //两个表联合查询
        //var_dump($food->field(‘a.food_id,b.user_id‘)->table(‘__FOOD__ a, __PERSON__ b‘)->select());
        $food =D(‘Food‘);
        var_dump($food->sql_one()->sql_two()->select());
        $this->display();
    }
    
    //控制器create()方法自动调用验证 
    //如果是直接 POST 过来的，直接使用 create()方法即可（假装下面是post过来的）
    public function login(){
    $person = D(‘Person‘); 
    $data[‘name‘] = ‘11‘; 
    $data[‘password‘] = ‘1‘; 
    $data[‘repassword‘] = ‘2‘;
    if ($person->create($data)) {
        echo ‘所有数据验证成功！‘; 
        } else { 
        var_dump($person->getError()); 
        }

    }
}

PersonModel层

<?php
namespace Home\Model;
use Think\Model;

class PersonModel extends Model {
    //批量验证 
    protected $patchValidate = true;
    //自动验证内容
    protected $_validate = array(
        array(‘name‘, ‘require‘, ‘用户名不得为空！‘, 0, ‘regex‘,3),
        //array(‘name‘, ‘email‘, ‘邮箱格式不正确！‘),
        //array(‘name‘, ‘url‘, ‘URL格式不合法！‘),
        //array(‘name‘, ‘currency‘, ‘货币格式不正确！‘),
        //array(‘name‘, ‘zip‘, ‘邮政编码必须是六位正整数！‘),
        //array(‘name‘, ‘number‘, ‘必须是正整数！‘),
        //array(‘name‘, ‘integer‘, ‘必须是整数！‘),
        //array(‘name‘, ‘double‘, ‘必须是浮点数！‘),
        //array(‘name‘, ‘english‘, ‘必须是纯英文！‘),
        //array(‘name‘, ‘/^\d{3,6}$/‘, ‘必须是3-6位纯数字‘, 0, ‘regex‘),
        //array(‘name‘, ‘李炎恢‘, ‘传递过来的值不相等‘, 0, ‘equal‘),
        //array(‘name‘, ‘李炎恢‘, ‘传递过来的必须不相等‘, 0, ‘notequal‘),
        array(‘repassword‘,‘password‘, ‘两个值不相等‘, 0, ‘confirm‘),
        array(‘name‘, ‘checkLength‘, ‘用户名必须在 3-5 位‘, 0, ‘callback‘, 3, array(3,5)),
    );
    
    //自定义验证方法
    protected function checkLength($str,$min,$max) {
        preg_match_all("/./", $str, $matches);
        $len = count($matches[0]); 
        if ($len < $min || $len > $max) { 
        return false; 
        } else { 
        return true; 
        } 
    }
    //将sql语句封装在模型定义类里
    protected $_scope =array(
        ‘sql_one‘=>array(
            ‘where‘=>array(‘food_id‘=>array(‘GT‘,3)),
        ),
        ‘sql_two‘=>array(
            ‘order‘=>array(‘unit_price‘=>‘DESC‘),
            ‘limit‘=>5,
        ),
    );
    //函数创建一个新的对象 PHP自带的函数
    public function __construct(){
        parent::__construct();
        var_dump(‘\Home‘);
    }
    
    
}
