TP引用樣式表和js文件及驗證碼

引入樣式表和js文件

<script src="__PUBLIC__/bootstrap/js/jquery-1.11.2.min.js"></script>
<script src="__PUBLIC__/bootstrap/js/bootstrap.min.js"></script>
<link href="__PUBLIC__/bootstrap/css/bootstrap.min.css" rel="stylesheet" type="text/css"></link>

?布局頁面

	<form action="__ACTION__" method="post">	<div class="panel panel-primary"><div class="panel-heading" style="text-align:center;"><h3 class="panel-title">登錄頁面</h3></div><div class="panel-body"><label class="col-sm-2 control-label yhm" id="yhm1">用戶名:</label><input type="text" class="form-control yhm" placeholder="請輸入用戶名" name="uid"> <label class="col-sm-2 control-label yhm" id="mm1">密碼:</label><input type="password" class="form-control yhm" placeholder="請輸入密碼" name="pwd"> <label class="col-sm-2 control-label yhm" id="yzm1">驗證碼:</label><input type="text" class="form-control yhm" placeholder="請輸入驗證碼" name="yzm"><div style="height:10px;"></div><img id="yzm" src="__CONTROLLER__/yzm" /></div><div class="panel-body" style="text-align:center;"><button type="submit" class="btn btn-primary btn-sm">點擊登錄</button> </div></div>

?js文件點擊刷新驗證碼

<script type="text/javascript">
$("#yzm").click(function(){var s = Math.ceil(Math.random()*100);//隨機生成0-100的整數$(this).attr("src","__CONTROLLER__/yzm/a/"+s);
})
$("#s").blur(function(){var s = $(this).val();$.ajax({url:"__CONTROLLER__/check",data:{s:s},type:"POST",dataType:"TEXT",success:function(data){alert(data);}})
})
</script>

?php文件

<?php
namespace Home\Controller;
use Think\Controller;
class LoginController extends Controller{public function login(){if(empty($_POST)){$this->show();}else{//驗證碼驗證//$_POST["yzm"];$y = I("post.yzm");$v = new\Think\Verify();//獲取驗證碼if($v->check($y)){//驗證碼是否正確//驗證用戶名密碼$uid = I("post.uid");$pwd = I("post.pwd");$db = D("Users");$arr = $db->find($uid);$mm = $arr["pwd"];if($mm==$pwd&&!empty($pwd)){session("uid",$uid);$this->success("登錄成功正在跳轉",U("Index/index"));}else{$this->error("用戶名或者密碼不正確！");}}else{$this->error("驗證碼不正確！");}}}public function yzm(){$v = new\Think\Verify();//實例化驗證碼類$v->entry();//引用獲取驗證碼的方法}public function check($s){$v = new\Think\Verify();if($v->check($s)){$this->ajaxReturn("驗證碼正確，請輸入用戶名和密碼！","eval");}else{$this->ajaxReturn("驗證碼不正確！","eval");}}
}

?======

驗證碼參數

public function yzm(){$v = new\Think\Verify();//實例化驗證碼類//$v->useImgBg = true;//$v->fontSize = "100";//$v->lenth = 3$v->entry();//引用獲取驗證碼的方法//如果好幾個驗證碼 可以用id區分//$v->entry(1);//然后check()方法后面多一個id參數如check($s,1)}

?可以在這里修改驗證碼的內容---------
