一、验证码
验证码参数
例题：登录时验证下验证码
LoginController.class.php
<?php namespace HomeController; use ThinkController; class LoginController extends Controller { public function Login() { if(empty($_POST)) { $this->display(); } else { //判断验证码是否正确 $code = $_POST["yzm"];//用户输入的验证码的值 $verify = new ThinkVerify(); //生成验证码 if($verify->check($code)) { if($_POST["uid"]!="") { $model = D("users"); $uid = $_POST["uid"]; $pwd = $_POST["pwd"]; $attr = $model->field("Pwd")->find($uid); //echo $attr["pwd"]; if($pwd == $attr["pwd"]) { session("uid",$uid); $this->success("登录成功","Main"); } else { $this->error("登录失败"); } } else { $this->error("登录失败"); } } else { $this->error("验证码错误"); } } } //生成验证码的操作 public function yzm() { $config = array( 'fontSize' => 30, // 验证码字体大小 'length' => 5, // 验证码位数 //'useNoise' => false, // 关闭验证码杂点 'imageW' => 200,//宽度 'imageH' => 100,//高度 //'useZh' => true,//中文验证码 //'fontttf' => 'Arvo-Regular.ttf',//指定验证码字体 ); $Verify = new ThinkVerify($config); //$Verify->fontttf = '7.ttf'; // 验证码字体使用 ThinkPHP/Library/Think/Verify/ttfs/5.ttf $Verify->entry(); }

二、文件上传
上传参数
每个文件信息又是一个记录了下面信息的数组，包括：
//文件上传 public function ShangChuan() { if(empty($_FILES)) { $this->display(); } else { $upload = new ThinkUpload();// 实例化上传类 $upload->maxSize = 3145728 ;// 设置附件上传大小 $upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型 //$upload->mimes = ''; $upload->rootPath = './Public/'; $upload->savePath = 'Uploads/'; // 设置附件上传目录 $upload->saveName = '';//保持上传文件名不变 // 上传文件 $info = $upload->upload(); var_dump($info); if(!$info) { $this->error($upload->getError()); } else { // 上传成功 获取上传文件信息 foreach($info as $file) { $url=$file['savepath'].$file['savename']; echo $url; $this->assign("url",$url); $this->display(); //$this->success('上传成功！'); } } } }
