回复讨论(解决方案)

贴出代码看下吧

做菜单栏部分代码

<div id="layerr12"  style="display:none;"><table width="175" height="23" border="0" cellpadding="0" cellspacing="0">        <tr>          <td width="44" height="24"> </td>          <td width="11" class="x1"> </td>          <td width="120" class="bs">&middot;<a href="infoli/list.php?wz=最新文章" target="forum">教育新闻</a></td>        </tr>	        <tr>          <td width="44" height="24"> </td>          <td width="11" class="x1"> </td>          <td width="120" class="bs">&middot;<a href="infoli/list.php?wz=ejajo专栏" target="forum">ejajo专栏</a></td>        </tr>		        <tr>          <td width="44" height="24"> </td>          <td width="11" class="x1"> </td>          <td width="120" class="bs">&middot;<a href="infoli1/list.asp" target="forum">资源共享</a></td>        </tr>		        <tr>          <td width="44" height="24"> </td>          <td width="11" class="x1"> </td>          <td width="120" class="bs">&middot;<a href="infoli/list.php?wz=家长教育" target="forum">家长教育</a></td>        </tr>	                 <tr>          <td width="44" height="24"> </td>          <td width="11" class="x1"> </td>          <td width="120" class="bs">&middot;<a href="infoli/list.php?wz=心灵鸡汤" target="forum">心灵鸡汤</a></td>        </tr>        <tr>          <td width="44" height="24"> </td>          <td width="11" class="x1"> </td>          <td width="120" class="bs">&middot;<a href="infoli/list.php?wz=新公告" target="forum">最新公告</a></td>        </tr>              </table> </div>

为什么第一次可以到list.php有用再传到add页面就是无效数据把“新”字删了就好了
诡异

如果用url传递中文的，任何时候都记得先urlencode，否则出错有的你哭
因为这牵涉到浏览器识别、浏览器传递、服务器识别、服务器传递给php这4个层面，如果这4个环节任意一个编码不对，都会导致无法识别参数。

改变为

"

其他地方同样对待，也就是说使用x.php?x=X这种格式传递时，一定要保证X的值是urlencode编码过的，特别是中文。
