thinkPHP实现的验证码登录功能示例

check(I('post.yanzhengma','','trim'))){ // 注释部分为另外一种从数据库中验证密码的方法 // $data['name'] = I('post.user_name'); // $data['psd'] = I('post.password'); // $row = M('user')->where($data)->find(); $name = I('post.user_name'); $psd = I('post.password'); $str = 'name ="'.$name. '" and tel = "'.$psd.'"'; var_dump($str); $row = M('user')->where($str)->find(); if($row) $this->redirect("Index/index"); else $this->redirect('login',1,'用户名或密码错误'); } else{ $this->redirect('login','验证码错误'); } } $this->display(); } public function verifyImg(){ //设置验证码的宽高字体大小以及验证码的个数，设计其他的参照ThinkVerify里面的设置 $config=array( 'imageW' => 150,'imageH' => 40,'fontSize' => 20,'length' => 4 ); $obj = new ThinkVerify($config); $obj->entry(); } }
