// 过滤非数据表字段更新    public function update(Request $request){        $user = model('User');        $result = $user -> allowField(true)->save($request->param(),['id'=>1]);        dump($result);    // 受影响的行数    }

//更新指定字段    public function update(Request $request){        $user = model('User');        $result = $user -> allowField(['name','email'])->save($request->param(),['id'=>9]);        dump($result);    }

数据库类更新数据（推荐）

 

public function update(Request $request){        $user = model('User');        $user->where('id',1)            ->update(['name'=>'chrdai']);    }

 

闭包更新数据（更新条件为多个时，推荐）

public function update(Request $request){        $user = model('User');        $user->save(['name'=>'chrdai'],function($query){            $query->where('status',1)->where('id','>',18);        });    }

 

静态方法更新数据

public function update(Request $request){        $user = model('User');        $user::where('id',1)            ->update(['name'=>'chrdai','email'=>'chrdai@qq.com']);    }

 

批量更新数据saveAll()

 

$user =model('User');$list = [    ['id'=>1, 'name'=>'thinkphp', 'email'=>'thinkphp@qq.com'],    ['id'=>2, 'name'=>'onethink', 'email'=>'onethink@qq.com']];$user->saveAll($list);
