Header is not working - php

Question

My header is not working.
<?php
$name = mysql_prep($_POST['name']);
$pastor = mysql_prep($_POST['pastor']);
$head = mysql_prep($_POST['head']);
$schedule = mysql_prep($_POST['schedule']);
$venue = mysql_prep($_POST['venue']);
$id = mysql_prep($_GET['ministryid']);
$errors = array();
$required_field = array('name', 'pastor', 'address', 'schedule', 'venue');
foreach ($required_field as $fieldname) {
if(!isset($_POST[$fieldname]) || empty($_POST[$fieldname])) {
$errors[] = $fieldname;
echo "Sorry, you missed to complete {$fieldname} <br />";
}
else {
$query = "UPDATE ministry SET
name = '{$name}',
pastor = '{$pastor}',
head = '{$head}',
schedule = '{$schedule}',
venue = '{$venue}'
WHERE id = {$id}";
mysql_query($query);
if(mysql_affected_rows() == 1) {
header('location: editministry.php?');
exit;
} else {
echo "Updating Failed on {$s_ministry['name']} <b />".mysql_error();
exit;
}
}
}
require_once("include/footer.php");
Every time I have successful update, the link change its address.
For example, when I'm updating id = 3, the address will change to editministry.php?ministryid=3.

You dont send anything along your URL, thats why your header won't work. Check for yourself.
if(mysql_affected_rows() == 1) {
header('location: editministry.php?');
exit;
Your link will become effectivly baseUrl/editministry.php?.It searches than for a variable, which is not defined. I am not sure how you actually can pass on a variable that you didnt define in a link, yet it sends you there. Don't know. But if you just tell it to the hard link without the questionmark, it should go to that page. For me it works at least within my code. For you it would be:
if(mysql_affected_rows() == 1) {
header('location: editministry.php' );
exit;
In my code it looks like this:
header( "Location: http://" . strip_tags( $_SERVER ['HTTP_HOST'] ) . "/newHolo/index.php" );
