PHP Header 302 Found - php

Question

I am trying to go back to the page i came from after the update is submitted.
the $pagefrom gets populated from the page before. that works fine. I get redirected to a page that says 302 found but its the same url as my current page.
<?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

I think something is wrong with
header('Location: '.$pagefrom);
but everything i try i still can not get it to reload the page before.

Answer 1

Remove echo $pagefrom; from the top of your script or move the header line above it. Headers can not be sent after output has started.
See: header

Answer 2

Try adding die(); the next line you use Header('Location: ....'); - if you don't the php will continue working further.
Also you probably want to use the form in the page the source code is from. Here you dont provide the pagename anymore therefore when you use form from this page - the $pagefrom is empty and redirection goes to current page.
Try adding it as hidden input for this form, and it should work.
