JS代码:
<script language="javascript" src="{dede:global name='cfg_cmspath'/}/include/dedeajax2.js"></script> <script language="javascript"> function CheckUser(){ var taget_obj = document.getElementById('_userboxform'); myajax = new DedeAjax(taget_obj,false,false,"","",""); myajax.SendGet2("{dede:global name="cfg_memberurl"/}/userboxsta.php"); DedeXHTTP = null; } </script>
然后我们修改下内容页部分的代码
找到:
<div class="userbox">
<dl>
<dd class="mtop">
<strong>用户名:</strong><input name="username" class="username" type="text" maxlength="20" />
<strong>密码:</strong><input name="pwd" class="password" type="password" maxlength="20" />
</dd>
将其修改为
<div class="userbox"> <dl> <dd class="mtop"> <span id="_userboxform"> <strong>用户名:</strong><input name="username" class="username" type="text" maxlength="20" /> <strong>密码:</strong><input name="pwd" class="password" type="password" maxlength="20" /> </span> </dd>即加上<span id="_userboxform">,用于判断用户是否已经登录。
下面我们来写一个PHP文件,用户传送数据,将其保存为/member/userboxsta.php,其代码如下:
<?php header("Pragma:no-cache "); header("Cache-Control:no-cache "); header("Expires:0 "); header("Content-Type: text/html; charset=gb2312"); //系统设置为维护状态可访问 $cfg_IsCanView = true; require_once(dirname(__FILE__)."/../include/inc_memberlogin.php"); $cfg_ml = new MemberLogin(); if(empty($cfg_ml->M_ID)){ echo ""; exit(); } $uid = $cfg_ml->M_LoginID; ?> <strong>欢迎您</strong>[<?php echo $cfg_ml->M_UserName?>],现在你可以直接发布留言
