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 Home\Controller; use Think\Controller; 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 \Think\Verify(); //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 \Think\Verify($config);//$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{$upload = new \Think\Upload();// 实例化上传类$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！'); }}} }
