一、验证码
1.页面前端显示 (验证码是图片标签,来源是控制器里的yzm()操作方法)
<h1>登录</h1> <form action="__ACTION__" method="post"> <div>用户名:<input type="text" name="uid"/></div> <div>密码:<input type="password" name="pwd"/></div> <div>验证码:<input type="text" name="yzm"/><img id="yzm" src="__CONTROLLER__/yzm"/></div> <input type="submit" value="登录"/> </form>
注意:点击验证码进行刷新,使用jq
<script type="text/javascript"> $(document).ready(function(e) { $("#yzm").click(function(){ $(this).attr("src","__CONTROLLER__/yzm"); }) }); </script>
2.后端验证码生成,操作方法yzm()
//生成验证码 function yzm() { $config=array( "footSize"=>15, "imgW"=>100, "imgH"=>15, "length"=>4, "useZh"=>true, ); $Verify=new \Think\Verify($config); //引用验证码类Verify $Verify->entry(2);//生成验证码标示为2 }
3.登陆后盾操作方法:Login()
function Login() { if(empty($_POST)) { $this->display(); } else { $code=$_POST["yzm"]; $verify=new \Think\Verify(); $z=$verify->check($code,2); //检测验证码 if($z) { if($_POST["uid"]!=""&&$_POST["pwd"]!="")//判断账号和密码是否为空 { $uid=$_POST["uid"]; $pwd=$_POST["pwd"]; $model=D("user"); $z=$model->field("pwd")->find($uid); if($z["pwd"]==$pwd) { session("uid",$uid); $this->success("登陆成功",U("Main/Main")); } else { $this->error("登陆失败","Login"); } } else { $this->error("用户名或密码不能为空","Login",1); } } else { $this->error("验证码错误!"); } } }
二、文件上传
1.文件上传前端:shangchuan.html
<body> <h1>文件上传</h1> <form action="__ACTION__" enctype="multipart/form-data" method="post"> <div><input type="file" name="photo"/></div> <div><input type="submit" value="提交"/></div> </form> </body>
2.后端操作方法:shangchuan()
//上传表单 function ShangChuan() { if(empty($_FILES)) { $this->display(); } else { $upload=new \Think\Upload();//实例化上传类 $upload->maxSize=3145728;//上传文件大小 $upload->exts=array("jpg","gif","png","jpeg");//上传文件格式 $upload->rootPath=‘./Public/Uploads/‘; //$upload->savaPath=‘Uploads/‘; $upload->saveName="" ; $info=$upload->upload(); //var_dump($info); if($info) { $this->success("上传成功"); } else { $this->error($upload->getError(),"ShangChuan"); } } }
三、获取ip地址
function ip() { $ip=get_client_ip(); //获取客户端ip地址 $IP=new Org\Net\Iplocation("UTFWry.dat"); //实例化类,参数表示ip地址库文件 $area=$IP->getlocation($ip); //获取某个ip地址所在的位置 }
