扩展一个Model基类
<?php class BaseModel extends Model{ use ValidationRules; public function rules(){} } /** * 验证参数规则 */ trait ValidationRules{ public $_data; public $errors = []; // 验证产生的错误 public $scene = ‘default‘; // 场景 [‘update‘,‘create‘] private $ok = true; /** * 验证数据 */ public function validate($data){ if($this->errors) $this->errors = []; $_rules = $this->rules(); $this->_data = $data; if(!$_rules) return true; if(!is_array($_rules)) throw new ErrorException(‘Model::rules必须为数组‘); foreach($_rules as $key => $val){ $this->checkRow($val); } return $this->ok; } public function addErrors($msg){ $this->errors[] = $msg; } //检查一行 private function checkRow(&$row){ if(count($row) < 2 || !is_array($row)) throw new ErrorException(‘Model::rules格式错误‘); if(isset($row[‘on‘]) && is_array($row[‘on‘]) && !in_array($this->scene,$row[‘on‘])) return true; // 如果 on 不是array 或者不是当前的场景 则忽略 如果没定义on 则是公用的 if(is_array($row[0])){ foreach($row[0] as $k => $v){ $this->checkField($v,$row[1],$row); } }elseif(is_string($row[0])){ $this->checkField($row[0],$row[1],$row); }else{ throw new ErrorException(‘Model::rules格式错误‘); } } //检查一个字段 private function checkField($field,&$func,&$row){ if($func instanceof Closure){ !$func($field,$row) && $this->ok = false; }elseif(is_string($func)){ if(!method_exists($this,$func)) throw new ErrorException(‘Model的方法:‘.$func.‘ 不存在‘); if( $func ==‘required‘ || (isset($this->_data[$field]) && $this->_data[$field] !=‘‘)){ !$this->$func($field,$row) && $this->ok = false; } }else{ throw new ErrorException(‘Model::rules格式错误‘); } } protected function required($field,&$row){ //必须的字段不能为空 其他的类型检查 可以为空(只有当有值且不符合规则的时候才为false) if(isset($this->_data[$field])?$this->_data[$field]==‘‘:true){ $this->addErrors($field.(isset($row[‘msg‘])?$row[‘msg‘]:‘不能为空‘)); return false; } return true; } protected function email($field,&$row){ if(!preg_match( "/^([0-9A-Za-z\\-_\\.]+)@([0-9a-z]+\\.[a-z]{2,3}(\\.[a-z]{2})?)$/i", $this->_data[$field])){ $this->addErrors($field.(isset($row[‘msg‘])?$row[‘msg‘]:‘格式错误‘)); return false; } return $this->checkLength($field,$row); } private function checkLength($field,&$row){ if(isset($row[‘max‘])?mb_strlen($this->_data[$field]) > $row[‘max‘]:false){ $this->addErrors($field."不能超过{$row[‘max‘]}个字"); return false; } if(isset($row[‘min‘])?mb_strlen($this->_data[$field]) < $row[‘min‘]:false){ $this->addErrors($field."不能少于{$row[‘min‘]}个字"); return false; } return true; } protected function phone($field,&$row){ if(!preg_match("/^1[34578]\d{9}$/", $this->_data[$field])){ $this->addErrors($field.(isset($row[‘msg‘])?$row[‘msg‘]:‘格式错误‘)); return false; } return true; } protected function number($field,&$row){ if(!preg_match(‘/^\s*[-+]?[0-9]*\.?[0-9]+([eE][-+]?[0-9]+)?\s*$/‘, $this->_data[$field])){ $this->addErrors($field.(isset($row[‘msg‘])?$row[‘msg‘]:‘格式错误‘)); return false; } return $this->checkLength($field,$row); } protected function integer($field,&$row){ if(!preg_match(‘/^\s*[+-]?\d+\s*$/‘, $this->_data[$field])){ $this->addErrors($field.(isset($row[‘msg‘])?$row[‘msg‘]:‘格式错误‘)); return false; } return $this->checkLength($field,$row); } protected function string($field,&$row){ if (!is_string($this->_data[$field])) { $this->addErrors($field.(isset($row[‘msg‘])?$row[‘msg‘]:‘格式错误‘)); return false; } return $this->checkLength($field,$row); } protected function files(){ // ‘ext‘ ‘maxSize‘,max , Multiple } protected function identical($field,&$row){ //一致 if(!isset($row[‘field‘])) throw new ErrorException(‘Model::identical必须定义field‘); if ($this->_data[$field] != $this->_data[$row[‘field‘]]){ $this->addErrors($field.(isset($row[‘msg‘])?$row[‘msg‘]:"与{$row[‘field‘]}不一致")); return false; } return true; } }
model中覆盖rules方法
<?php class User extends BaseModel{ public $table_name = "user"; public function rules(){ // required email phone number integer string identical return [ [[‘username‘,‘password‘],‘required‘], [‘password2‘,‘required‘,‘on‘=>[‘create‘]], [‘email‘,‘email‘,‘msg‘=>‘邮箱错了‘,‘max‘=>50], [‘phone‘,‘phone‘], [‘phone‘,‘required‘,‘on‘=>[‘update‘]], [‘score‘,‘number‘], [‘tags‘,function($field,$row){ if(!isset($this->_data[$field]) || !is_array($this->_data[$field])){ $this->addErrors($field.(isset($row[‘msg‘])?$row[‘msg‘]:‘格式错误‘)); return false; } return true }], [‘age‘,‘integer‘], [[‘username‘,‘password‘],‘string‘,‘max‘=>32,‘min‘=>6], [‘password2‘,‘identical‘,‘field‘=>‘password‘], ]; } }
Controller中调用
$model = new User(); $model->scene = ‘update‘; // $a = $model->validate([‘username‘=>‘admin1‘,‘password‘=>‘123456‘,‘email‘=>‘[email protected]‘,‘phone‘=>‘14526396857‘,‘score‘=>2.0,‘age‘=>2,‘password2‘=>‘123456‘]); $a = $model->validate([]); var_dump($a); print_r($model->errors);
