登陆前后导航栏处理 2015-12-12，导航栏2015-12-12

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">
      
            <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>
    
            <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>
