下面我们来一步一步修改！
首先在index.html中删掉原来的登陆代码，在头部文件head.html加入以下新的代码：
<div id="_userlogin">
<form name="userlogin" action="{dede:global.cfg_memberurl/}/index_do.php" method="POST">
<input type="hidden" name="dopost" value="login" />
<span>用户名:</span>
<input type="text" name="userid" size="10" class="ipt-txt" />
<span>密码:</span>
<input type="密码" name="pwd" size="10" class="ipt-txt" />
{dede:php}
if(preg_match("#2#", $safe_gdopen)){
echo '
<span>验证码:</span>
<input type="text" name="vdcode" size="8" class="ipt-txt" />
<img id="vdimgck" align="absmiddle" style="cursor:pointer;margin-left:0px;text-transform:uppercase;" alt="看不清？点击更换" src="'.$cfg_cmspath.'/include/vdimgck.php"/>';}
{/dede:php}
<button type="submit" class="btn-1">登录</button>
<a href="{dede:global.cfg_memberurl/}/index_do.php?fmdo=user&dopost=regnew" >注册帐号</a> <a href="{dede:global.cfg_memberurl/}/reset密码.php">忘记密码?</a>
</form>
</div>
<script language="javascript" type="text/javascript">CheckLogin();</script>
HTML代码现在我们已经有了，下面把上面代码中用到的CSS样式完善了：
/*---------- head ---------*/
.header{
width:100%;
width:960px;
margin:auto;
overflow:hidden;
}
.header_top{
height:32px!important;
height:31px;
line-height:32px;
color:#676767;
overflow:hidden;
background:url(../images/top_bg.gif) repeat-x;
}
.center{
margin:0px auto;
}
.w960{
width:960px;
/*position:relative;*/
}
.header_top .time{
float:left;
padding-left:10px;
}
.header_top .toplinks{
float:right;
text-align:right;
}
.header_top .toplinks a{
margin:0 5px;
}
.header .top{
clear:both;
overflow:hidden;
margin-top:10px;
}
.header .title{
float:left;
}
.header .title h1 a{
width:386px;
height:58px;
display:block;
overflow:hidden;
}
.header .banner{
width:434px;
height:55px;
float:right;
margin-left:20px;
overflow:hidden;
}
.ipt-txt{
width:100px;
border:1px #CFCFCF solid;
}
.fb{
color:#333333;
}
.btn-1{
background: url("../images/comm-bt.gif") no-repeat scroll 0 0 transparent;
border: medium none;
color: #585858;
cursor: pointer;
height: 24px;
letter-spacing: 1px;
line-height: 25px;
overflow: hidden;
width: 70px;
}
HTML代码和CSS都有了，现在显示是没问题了，但要正常登入，还少一些JS文件要加载：
<script language="javascript" type="text/javascript" src="{dede:global.cfg_cmsurl/}/include/dedeajax2.js"></script>
<script language="javascript" type="text/javascript">
<!--
$(function(){
$("a[_for]").mouseover(function(){
$(this).parents().children("a[_for]").removeClass("thisclass").parents().children("dd").hide();
$(this).addClass("thisclass").blur();
$("#"+$(this).attr("_for")).show();
});
$("a[_for=uc_member]").mouseover();
$("a[_for=flink_1]").mouseover();
});
function CheckLogin(){
var taget_obj = document.getElementById('_userlogin');
myajax = new DedeAjax(taget_obj,false,false,'','','');
myajax.SendGet2("{dede:global.cfg_cmspath/}/member/ajax_loginsta.php");
DedeXHTTP = null;
}
-->
</script>
