Hi,

I have a login page. User first enters information and submits the form.

And I have a php script that will see if the user exists.

If( authenticated == true)
{
// I do a redirect
}
else
{
// I want to popup an error message on the same page.
}

1) I'm not sure how to show the popup message, I would like to make my div element visible with an error message returned from the server,
I would have to use Ajax, right? But how?

Or are there alternatives which are just as good.
