JavaScript not executing with header function

Question

I want to execute a JavaScript after update or delete operation. but the problem is the JavaScript does not show up and straight go to other page.

Here is my code:

<?php
session_start();

$con = mysql_connect("localhost","root","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("carrental", $con);
$password1 = $_POST['password1'];
$userid =$_SESSION['SESS_MEMBER_ID'];

mysql_query("UPDATE user SET password='$password1' WHERE user_id='$userid'");
echo "<script>alert('Password has been changed.')</script>";
header("location: adminProfile.php");
mysql_close($con);
?>

I try to use include instead of header and it executed with a Notice. Need some advise..

You probably want to change the location from js as well after the alert returns — Offbeatmammal

Try this:

In PHP, header function will not work if you use echo function in whole the page script.

Replace the line:
header("location: adminProfile.php");

with
echo '<script>window.location = "adminProfile.php";</script>';

Let me know if you need more help.

Use for redirect

<script>
  window.location = "adminProfile.php";
</script>

if you use a location header the browser will receive a redirect request and document.location will change (at which point no javascript can run),

so, do the redirect, or the javascript.

you could try combining a refresh header instead of a location header, or do a javascript redirect after the alert.

header will never work if you will echo anything or try to print anything before that even space.

echo "<script>alert('Password has been changed.')</script>";// do not use this line.before
header("location: adminProfile.php");
