TP引用样式表和js文件及验证码

引入样式表和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>

 布局页面

	<form action="__ACTION__" method="post">	
		<div class="panel panel-primary">
			<div class="panel-heading" style="text-align:center;">
				<h3 class="panel-title">登录页面</h3>
			</div>
			<div class="panel-body">
				<label class="col-sm-2 control-label yhm" id="yhm1">用户名:</label>
				<input type="text" class="form-control yhm" placeholder="请输入用户名" name="uid"> 
				<label class="col-sm-2 control-label yhm" id="mm1">密码:</label>
				<input type="password" class="form-control yhm" placeholder="请输入密码" name="pwd"> 
				<label class="col-sm-2 control-label yhm" id="yzm1">验证码:</label>
				<input type="text" class="form-control yhm" placeholder="请输入验证码" 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">点击登录</button> 
			</div>
		</div>

 js文件点击刷新验证码

<script type="text/javascript">
$("#yzm").click(function(){
	var s = Math.ceil(Math.random()*100);//随机生成0-100的整数
	$(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 HomeController;
use ThinkController;
class LoginController extends Controller{
    public function login(){
        if(empty($_POST)){
            $this->show();
        }else{
            //验证码验证
            //$_POST["yzm"];
            $y = I("post.yzm");
            $v = newThinkVerify();//获取验证码
            if($v->check($y)){//验证码是否正确
                //验证用户名密码
                $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("登录成功正在跳转",U("Index/index"));
                }else{
                    $this->error("用户名或者密码不正确！");
                }
            }else{
                $this->error("验证码不正确！");
            }
        }
        
    }
    public function yzm(){
        $v = newThinkVerify();//实例化验证码类
        $v->entry();//引用获取验证码的方法
    }
    public function check($s){
        $v = newThinkVerify();
        if($v->check($s)){
            $this->ajaxReturn("验证码正确，请输入用户名和密码！","eval");
        }else{
            $this->ajaxReturn("验证码不正确！","eval");
        }
    }
}

 ======

验证码参数

public function yzm(){
		$v = newThinkVerify();//实例化验证码类
		//$v->useImgBg = true;
		//$v->fontSize = "100";
		//$v->lenth = 3
		$v->entry();//引用获取验证码的方法
		//如果好几个验证码 可以用id区分
		//$v->entry(1);
		//然后check()方法后面多一个id参数如check($s,1)
	}

 可以在这里修改验证码的内容---------
