How to open a popup window if login successful

106 New Member

Hi guys, i am currently doing a php app for school and the question is this, how can i make a popup window appear if the login is successful and redirect to another page (for example index.php) automatically in, lets say, 5 secs?

My login page as the following code (i am portuguese so some things are in PT but just say and i will translate),

 <?php require_once('Connections/Info_Registos.php'); ?>

<?php

Hi Slaxer,

In the code block

Expand|Select|Wrap|Line Numbers

 
if ($loginFoundUser) {

     $loginStrGroup = "";

You can add:

Expand|Select|Wrap|Line Numbers

?><script>alert("Login successful!")</script><?php

Hope that helps!

how can i make a popup window appear if the login is successful and redirect to another page (for example index.php) automatically

hm, what is the point of a popup if you redirect anyways?

PS. Don’t let DreamWeaver make your PHP code, that’s always a sore sight. better use Prepared Statements if you want to be protected from SQL Injection.

Hi mate,

The code i have has been retrieved from the web. This is just a school work and i'm still a newbie at this. Any tips will be much appreciated.

Hi computerfox,

Could you write how the code should be? i tried but it hasn't been working.

Thanks to both ;)

Peace,

since you’re new, don’t start to learn the outdated and deprecated mysql extension. better use mysqli or PDO (personally I recommend PDO over MySQLi, because it’s more straightforward to use).

Also, as Dorm mentioned, why do you want to add a popup for the confirmation and then redirect to another confirmation? Seems un-needed. And yeah, don't use Dreamweaver, Notepad or Notepad++ work better. Or if you're on a Unix/Linux based machine, use vim.
