Tp-validate进阶thinkphp
阶段1:基础
application/controller/v1/Banner.php
<?php namespace app\api\controller\v1; use think\Controller; use think\validate; class Banner extends controller{ public function index(){ //http://localhost/thinkphp5/public/index.php/api/v1.Banner/index } public function getBanner(){ $data=array( 'name'=>'dash', 'email'=>'wolichihua2011@163.com' ); //独立验证 $validate=new Validate([ 'name'=>'require|max:10', 'email'=>'email' ]); //batch()批量验证 否则只返回最后一个getError验证信息 $result=$validate->batch()->check($data);//返回布尔 var_dump($result); var_dump($validate->getError());//返回错误信息 } }
阶段二:讲=将验证规则单独放到其他的类文件中
<?php namespace app\api\controller\v1; use think\Controller; use think\validate; //use app\api\validate\TestValidate; class Banner extends controller{ public function index(){ //http://localhost/thinkphp5/public/index.php/api/v1.Banner/index } public function getBanner($id){ $data=array( 'name'=>'dash', 'email'=>'wolichihua2011@163.com' ); //验证器 直接new $validate= new \app\api\validate\TestValidate(); //或者引入命名空间在new use app\api\validate\TestValidate (application/api/validate/TestValidate.php) $validate= new TestValidate();//必须有这个命名空间 use app\api\validate\TestValidate //batch()批量验证 否则只返回最后一个getError验证信息 $result=$validate->batch()->check($data);//返回布尔 var_dump($result); var_dump($validate->getError());//返回错误信息 } }
application/api/validate/TestValidate.php
<?php namespace app\api\validate; use think\Validate; class TestValidate extends Validate{ protected $rule =[ 'name'=>'require|max:10', 'email'=>'email' ]; }
阶段三:封装验证参数:
application/controller/v1/Banner.php
<?php namespace app\api\controller\v1; use think\Controller; use think\validate; use app\api\validate\IDMustBePositiveInt; class Banner extends controller{ public function index(){ http://localhost/thinkphp5/public/index.php/api/v1.Banner/index } public function getBanner($id){ (new IDMustBePositiveInt())->goCheck(); } }
application/api/validate/BaseValidate.php
<?php namespace app\api\validate; use think\Request; use think\Validate; use think\Exception; class BaseValidate extends Validate{ public function goCheck(){ // 获取http参数 // 对这些参数做检验 $request= Request::instance(); $params=$request->param(); $result=$this->check($params); if (!$result) { $error=$this->error; throw new Exception($error, 1); }else{ return true; } } }
application/api/validate/IDMustBePositiveInt.php
<?php namespace app\api\validate; class IDMustBePositiveInt extends BaseValidate{ protected $rule=array( 'id'=>'require|isPositiveInteger' ); //自定义验证规则 protected function isPositiveInteger($value, $rule='', $data='', $field='') { if (is_numeric($value) && is_int($value + 0) && ($value + 0) > 0) { return true; } return $field . '必须是正整数'; } }
阶段4:讲自定义规则挪到BaseValidate.php中,其他自定义的也一样只保留rule规则就行了
阶段5:创建更多的自定义验证类
阶段六:自定义验证类文件多了,就需要工厂类来封装啦!
