PHP Redirect stopped working? - php

Question

I have wrote a script to update a MySql DB from a form.
After the DB has been updated I want the page to auto redirect to another page.
This has been working fine however since switching hosting provider non of my sites re-directs work.
Here is the code:
<?php
$servername = "localhost";
$username = "XXX";
$password = "XXX";
$dbname = "XXX";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$id= $_POST[id];
$dob=$_POST[dob];
$sql=("update users set dob='$dob' where id='$id'")or die('Error 23 ' . mysql_error());
if ($conn->query($sql) === TRUE) {
echo "Updated successfully<br /><br />";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
?>
<?php
header("location:index.php?action=updated"); ?>
When I run the code the DB updates but the page just displays Updated successfully?

Answer 1

try using javascript to redirect like below:
if ($conn->query($sql) === TRUE) {
echo "<script>
alert('Updated successfully');
window.location.href = 'index.php?action=updated';
</script>";
}

Answer 2

Don't echo anything and try to redirect afterwards. Instead simply redirect without any echoing.
if ($conn->query($sql) === TRUE) {
header("location:index.php?action=updated");
exit;
} else
echo "Error: " . $sql . "<br>" . $conn->error;

Answer 3

try this :
<?php
ob_start();
header('Location: http://www.example.com/index.php?action=updated', true);
?>
