我正在尝试在提交表单时自己进行div显示。我有以下代码，我无法弄清楚如何解决这个问题。
<?php
session_start();
$locale_db_host = 'localhost';
$locale_db_name = 'xxxx';
$locale_db_login = 'xxxx';
$locale_db_pass = 'XXXX';
// connect to db
$linkmb = mysql_connect($locale_db_host, $locale_db_login, $locale_db_pass)
or die("Could not connect : " . mysql_error());
//echo "Connected successfully\n";
mysql_select_db($locale_db_name, $linkmb) or die("Could not select database $locale_db_name");
if(isset($_POST['submit']))
{
$sdate=$_POST['time3'];
$edate=$_POST['time5'];
$query=$_POST['query'];
$output=$_POST['output'];
$_SESSION['time3']="$sdate";
$_SESSION['time5']="$edate";
$t=time();
$filename="/var/www/html/dialer/output/$t.csv";
}
?>
<div id="dialer">
<form name="dialer" id="dialer" action="" method="post" enctype="multipart/form-data" onsubmit="showHide(); return false;">
<input type="hidden" name="mode" id="mode" value="insert" />
