注意：添加灰色背景处，关于ajax传值，和js的判断
1 登陆后控制器处理：判断是否登陆并传递用户信息
class IndexController extends HomeBaseController { //登录 public function index() { $id=I("get.id"); $users_model=M("Users"); $user=$users_model->where(array("id"=>$id))->find(); if(empty($user)){ $this->error("查无此人！"); } $this->assign($user); $this->display(":index"); } function is_login(){ if(sp_is_user_login()){ $this->ajaxReturn(array("status"=>1,"user"=>sp_get_current_user())); }else{ $this->ajaxReturn(array("status"=>0,"info"=>"此用户未登录！")); } }
。。。。。。
2 登陆前后主页导航栏的 登陆和未登录 的显示
<div id="main-menu-user"> <!--还未登陆--> <div class='userout user' > <ul class="nav navbar-nav navbar-right"> <li> <a href="{:u('user/register/index')}" data-toggle="dropdown">注册</a> </li> </ul> <ul class="nav navbar-nav navbar-right"> <li> <a href="{:u('user/login/index')}" data-toggle="dropdown">登陆</a> </li> </ul> <ul class="nav navbar-nav navbar-right" style="margin-top:10px"> <li > <img src="__TMPL__/Public/img/headicon.png" class="headicon"/> </li> </ul> </div> <!--已经登陆--> <div class="userlogin user" > <ul class="nav navbar-nav navbar-right"> <li> <a href="{:u('user/index/logout')}" data-toggle="dropdown">退出</a> </li> </ul> <ul class="nav navbar-nav navbar-right"> <li> <a href="{:u('user/center/index')}" data-toggle="dropdown" class="user-nicename"></a> </li> </ul> <ul class="nav navbar-nav navbar-right" style="margin-top:10px"> <li > <img src="" class="headicon"/> </li> </ul> </div></div>
3 登陆后，js对box的操作
<script>
$(function () {/*控制导航栏显示登陆还是个人中心*/ $.post("{:U('user/index/is_login')}",{},function(data){ if(data.status==1){ if(data.user.avatar){ $("#main-menu-user ul li .headicong").attr("src",data.user.avatar.indexOf("http")==0?data.user.avatar:"__UPLOAD__avatar/"+data.user.avatar); } $("#main-menu-user ul li .user-nicename").text(data.user.user_nicename!=""?data.user.user_nicename:data.user.user_login); $("#main-menu-user .userlogin").show(); $("#main-menu-user .userout").hide(); } if(data.status==0){ $("#main-menu-user .userout").show(); $("#main-menu-user .userlogin").hide(); }}); });</script>
