progress bar

[Ron Croonenberg]

Hello,

I have a window where it could take a while to display the info. While
waiting I want to display a "progress bar". Once the info is ready to be
displayed I want the "progress bar" to disappear.

Can this easiest be done with an animated gif ? if so, how do I make
that gif disappear with php ?

thanks,

Ron

You can't.

PHP is a server-side language. By the time the page has been delivered to
the browser the PHP script has finished processing.

You'd have to do this is a client-side language like JavaScript.

This isn't possible with PHP alone. The best way to do this now days
is to use javascript. With javascript you can now create a wide range
interactive effects on your website using what is known as "AJAX". Do
a search on google to find some tutorials regarding the subject. I'll
hint you in the obj.hide() direction :)

When you press the submit button, the page will wait to get replaced. This
is your queue to show the progress bar.

If the upload script sends a Location header after it has finished, you can
let the page reload without the progress bar.
