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>

</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>
