Question

我正在尝试返回提交更新后我来自的页面。 $ pagefrom从之前的页面填充。工作正常。我被重定向到一个页面，该页面显示302找到但与我当前页面的URL相同。

<?php
{
$pagefrom=  $_POST['pagename'];

echo $pagefrom;

if(isset($_POST['add']))
{



$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
  die('Could not connect: ' . mysql_error());
}

if(! get_magic_quotes_gpc() )
{
   $Reg_F_Name = addslashes ($_POST['Reg_F_Name']);
   $Reg_L_Name = addslashes ($_POST['Reg_L_Name']);
}
else
{
   $Req_F_Name = $_POST["Req_F_Name"]; 
   $Reg_L_Name = $_POST["Reg_L_Name"];
}
$Req_ID = $_POST["Req_ID"]; 
$Req_F_Name = $_POST["Req_F_Name"]; 
$Reg_L_Name = $_POST["Reg_L_Name"];
$Reg_Email = $_POST["Reg_Email"];
$Reg_Mod_Request = $_POST["Reg_Mod_Request"];
$Reg_Address_1 = $_POST["Reg_Address_1"];
$Reg_Address_2 = $_POST["Reg_Address_2"];
$Reg_City = $_POST["Reg_City"];
$Reg_State = $_POST["Reg_State"];
$Reg_Zip_Code= $_POST["Reg_Zip_Code"];
$Reg_ID= $_POST["Reg_ID"];
$Reg_Phone = $_POST["Reg_Phone"];
$Reg_Phone= str_replace("-","","$Reg_Phone");
$Reg_Approval_Status= $_POST["Reg_Approval_Status"];
$Reg_Status= $_POST["Reg_Status"];

$sql= "UPDATE $dbtable SET
 Reg_F_Name = '$Reg_F_Name',
 Reg_L_Name = '$Reg_L_Name',
 Reg_Phone = '$Reg_Phone',
 Reg_Email = '$Reg_Email',
 Reg_Mod_Request = '$Reg_Mod_Request',
 Reg_Address_1 = '$Reg_Address_1',

 Reg_State = '$Reg_State',
 Reg_Zip_Code = '$Reg_Zip_Code',

mysql_select_db($database);
$retval = mysql_query( $sql, $conn );
if(! $retval )
{
  die('Could not enter data: ' . mysql_error());
}

mysql_close($conn);
header('Location: '.$pagefrom);
}

我觉得有些不对劲标题（'Location：'。$ pagefrom）; 但我尝试的一切我仍然无法让它重新加载页面之前。

Answer 1

删除echo $ pagefrom;从脚本顶部或移动它上面的标题行。输出开始后，无法发送标题。

请参阅：header

Answer 2

尝试添加die();您使用的下一行Header('Location: ....'); - 如果您不这样做，php将继续进一步工作。您也可能希望使用源代码所在页面中的表单。因此，当您使用此页面中的表单时，您不再提供pagename - $pagefrom为空，重定向将转到当前页面。尝试将其添加为此表单的隐藏输入，它应该可以正常工作。
