一、驗證碼
?
驗證碼參數
例題：登錄時驗證下驗證碼
LoginController.class.php
<?php namespace Home\Controller; use Think\Controller; class LoginController extends Controller {public function Login(){if(empty($_POST)){$this->display(); } else{//判斷驗證碼是否正確$code = $_POST["yzm"];//用戶輸入的驗證碼的值$verify = new \Think\Verify(); //生成驗證碼 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);$this->success("登錄成功","Main");}else{$this->error("登錄失敗"); }}else{$this->error("登錄失敗"); }}else{$this->error("驗證碼錯誤"); }}}//生成驗證碼的操作public function yzm(){$config = array( 'fontSize' => 30, // 驗證碼字體大小 'length' => 5, // 驗證碼位數 //'useNoise' => false, // 關閉驗證碼雜點'imageW' => 200,//寬度'imageH' => 100,//高度//'useZh' => true,//中文驗證碼//'fontttf' => 'Arvo-Regular.ttf',//指定驗證碼字體 );$Verify = new \Think\Verify($config);//$Verify->fontttf = '7.ttf'; // 驗證碼字體使用 ThinkPHP/Library/Think/Verify/ttfs/5.ttf$Verify->entry(); }

二、文件上傳
上傳參數
每個文件信息又是一個記錄了下面信息的數組，包括：
?
//文件上傳public function ShangChuan(){if(empty($_FILES)){$this->display(); }else{$upload = new \Think\Upload();// 實例化上傳類$upload->maxSize = 3145728 ;// 設置附件上傳大小$upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 設置附件上傳類型//$upload->mimes = '';$upload->rootPath = './Public/';$upload->savePath = 'Uploads/'; // 設置附件上傳目錄$upload->saveName = '';//保持上傳文件名不變// 上傳文件 $info = $upload->upload();var_dump($info);if(!$info){$this->error($upload->getError());}else{// 上傳成功 獲取上傳文件信息foreach($info as $file){ $url=$file['savepath'].$file['savename'];echo $url;$this->assign("url",$url);$this->display();//$this->success('上傳成功！'); }}} }
