Temporary output (please wait screen)

Hi

I have never done this before... but I could use it now.

How do I create a "please wait" page, which will "reload" once my real
page is ready?
I am talking of a waiting time of some 10-20 secs, but can be
worse.... still even 10 secs I'd like something telling the user, that
data is being processed.

[like when booking an airline ticket... waiting 2 mins there is
common]

Not possible using PHP, look for a javscript solution (which could poll a
php script to see if something is complete).

Keywords to look for: javascript, setTimeOut, XMLHTTPRequest,
window.location
Questions? -> comp.lang.javascript

Output your message, process the info, cache it, html reload, done.
The only problem is that you have to deal carefully with private info,
but it's really affordable.

You don't actually need to reload - as long as the job will complete
before the browser times out, write the 'please' wait inside a div,
flush it, then when the final output is ready make the div invisible
with javascript.

There is no guarantee the browser will display anything before all
output is sent.

True - but it works on every browser I've tested (MSIE, Firefox,
Konqueror)...and of course its dependant on having a webserver capable
of generating chunked encoding.

Perhaps I should say YMMV.

Yep, there are three possible reasons for this not being displayed:

1. PHP buffers may not be full (but can be flushed manually)
2. Web server buffers may not be full (no control but often flushed when
you flush the php buffers)
3. The browser may get the data but not display it.

Like you, I've found generally it works. But not necessarily always.

Now it may be OK with the op if the message only shows 95% of the time
and misses 5% of the customers. I mean - a "please wait" isn't the most
important message in the world :-).

But if he does want it to show up 100% of the time, he should be looking
at the other methods proposed here.

This kind of thing is usually done client side with JavaScript. The
jQuery library has a couple of plugins for doing it, the best known
one being BlockUI

Have to agree with Jerry here. I've had very mixed results with
browsers displaying the content before the whole page has finished
loading, even after using flush techniques.

One way to help the browser along is to output a stream of data that
causes it to flush it's own buffers, such as a stream of HTML
comments.
