Display a temporary screen during search

[Anon]

Hey Guys :-)

I do a huge SELECT on a database and the results are taking time to be displayed.
I'd like to inform the user about the wait with a temporary screen such as "Please wait, your search is beeing proceeded".
Best of all if the message can be refreshed, that would be nice.
Does someone have an idea about a cool way to implement that?
As a matter of fact, I was wondering if it was possible with php?

Thx for help

The solution to this is to think about when the variables from the form are sent and when the response is delivered.

Once the variables are sent nothing will come back to the browser until the response has been formed. This is why a user presses Submit and then waits half an hour for the response and it looks like nothing's happening.

The solution is this:

Don't post the variables to the search page.

Post the variables to another page - a temporary page that doesn't have to look anything up. This page will be returned quickly and say "Please wait..." or whatever.

Put in this page a META refresh tag calling the search page with all the varibles you posted in the URL (GET variables). This page will the force the browser to call the search page but will display "Please wait..." until it gets the response from the server.

If you need an example just email me.

Hi,

The problem with this is that the page, including all images it contains, for instance, will not be loaded from the browser's cache, but will be completely re-fetched. That is okay for the "page" alone, as the results change, but all the images are reloaded too 🙁
