Answer 1

你传一个隐藏  是干什么的 ？  你仔细看你打印出来的数组 ，echo $_POST['pagetext']['data1']    你看看 有值没有    要仔细看啊 你的值是有的 2013-12-09

Array ( 
            [enews] => EditUserpage 
            [id] => 8 
            [oldpath] => ../../databott.php 
            [cid] => 0
            [gid] => 1 
            [pagemod] => 1 
            [title] => 每日余额主体 
            [path] => ../../databott.php 
            [classid] => 0 
            [pagetitle] => 
            [pagekeywords] => 
            [pagedescription] => 
            [pagetext] => Array ( 
                    [data1] => 2013-12-09 
                    [Submit] => 查询 
                    [action] => submitted 
                ) 
            )

你把 数组格式化打印输出 就清楚多了！！希望以后你能仔细

Answer 2

<input tabIndex=3 maxLength=10 size=10 type="text" name="data1" class="Wdate" onClick="WdatePicker()" /> WdatePicker()是个日历插件吧。你确定已经调用了？不然会没有值的

<form id="form1" name="form1" method="post" action="" target="" enctype="multipart/form-data">
<input type="text" name="data1" class="Wdate"/>
<input style="COLOR: #008000" tabIndex=1 type="submit" name="Submit" value="查询" />
</form>
<BR><BR><BR><BR><BR><BR><BR>
<?php
header('Content-Type:text/html;charset=utf8');
if (isset($_POST['Submit'])){echo "后面是什么呀";echo $_POST['data1'];} ?>
