Discuz! X3.1 判断会员登录状态及外部调用注册登录框的实现代码

在帝国的html里加入html代码

<div class="login"> 
    <form id="login-form" action="/login.shtml" method="post"> <div class="row username"> 
       <label for="LoginForm_username" class="required">用户名 <span class="required">*</span></label>  <input size="30" class="px" autocomplete="off" tabindex="1" name="LoginForm[username]" id="LoginForm_username" type="text" /> <a title="" href="http://bbs.jb51.net/member.php?mod=register&referer=http://ka.18183.com/">立即注册</a><div class="clear"> </div> 
<div class="errorMessage" id="LoginForm_username_em_" style="display:none"></div>    </div> 
<div class="row userpwd"> 
<label for="LoginForm_password" class="required">密码 <span class="required">*</span></label> <input size="30" class="px" autocomplete="off" tabindex="2" name="LoginForm[password]" id="LoginForm_password" type="password" /> <a title="" href="#">找回密码</a> 
<div class="clear"> </div> 
<div class="errorMessage" id="LoginForm_password_em_" style="display:none"></div>    </div> 
  
<div class="row rememberMe"> 
<input id="ytLoginForm_rememberMe" type="hidden" value="0" name="LoginForm[rememberMe]" /><input tabindex="4" name="LoginForm[rememberMe]" id="LoginForm_rememberMe" value="1" type="checkbox" />        <label for="LoginForm_rememberMe">自动登录</label>     <div class="errorMessage" id="LoginForm_rememberMe_em_" style="display:none"></div><div class="clear"> </div> 
                </div> 
  
    <div class="row login_btn"> 
        <input class="pn pnc" type="submit" name="yt0" value="登录" />        <a title="" href="http://bbs.jb51.net/connect.php?mod=login&op=init&referer=http://www.jb51.net/" class="qq">QQ登录</a><div class="clear"> </div> 
                        </div> 
  
                    </form> 
                </div> 
            <div class="info" style="display:none"> 
                  
                <div class="info_img"></div> 
                <div class="info_info"> 
                    <div class="info_info_name">dfsafd23eedsafd@qq.com</div> 
                    <div class="info_info_links"> 
                        <a target="_blank" href="<?=$public_r[add_www_92game_net_bbsurl]?>/home.php?mod=spacecp&ac=credit">我的积分</a>|<a href="/boom.shtml" target="_blank" >我的礼包</a>
 
                        <a target="_blank" href="<?=$public_r[add_www_92game_net_bbsurl]?>/home.php?mod=space&do=notice&view=system">提醒</a>|<a href="/logout.shtml">退出</a> 
                    </div> 
                </div> 
                <div class="clear"> </div> 
                <div class="info_txt"> 
                      
                </div> 
            </div>

在discuz下写个zxf_userinfo.php放在discuz根目录就可以了

<?php 
require './source/class/class_core.php'; 
$discuz = & discuz_core::instance(); 
$discuz->init_cron = false; 
$discuz->init_session = false; 
$discuz->init(); 
//echo $_G['uid']; 
echo $_G['uid'].'|'.$_G['username'].'|0'; 
?>

在页面下方利用ajax获取该页面的值，不多说了，直接看代码吧

<script> 
$(document).ready(function(){  
        var bbsurl='http://bbs.jb51.net/'; 
    var url=bbsurl+'/zxf_userinfo.php'; 
        var uid,uname,uscore; 
    $.ajax({type: "GET",url: url,data: "?"+Math.random(),dataType: "text",success: function(a){ 
        for (var c = a.split("|"),  d = 0; d < c.length;){uid = c[d++],uname= c[d++],uscore= c[d++];} 
              if(uid){   
        $('.login').remove();   
        $('.info').show();   
        $('.info_info_name').html(uname); 
                $('.info_img').html('<a href="#"><img src='+bbsurl+'/uc_server/avatar.php?uid='+uid+'&size=small /></a>'); 
          }   
          else{   
        $('.info').remove();   
        $('.login').show();   
          }   
    }}); 
  
      
});  
</script>
