wait screens

[gnome354]

I would like to create wait pages as seen on this site (php builder) to show users while waiting for time intensive processes to finish.

For example, if user X requested to see information which will take the system 30 seconds or more to process. I would like to display a screen that says something to the effect of "Please wait while gathering information."

Can anyone help me or point me in the right direction?

Do it through a meta tag or header() function,
Set the delay you want to have when the system is busy.

You can do it in a couple of ways.

If you know it'll be a maximum amount of time then use a META tag redirect to a specific URL and then on to the second page.

Another way might be to send the query over and do something like include a "wait" page in your code (or echo it out) and then run the query, do your stuff to the result set and once that is run the code will display the final page either by echo/print statements of by sending evrything to the final page.

For instance I usually use a template system so I might do the following steps:

1. collect my query from input form
2. display wait page template
3. run the query
4. run my data modifications and build html strings or whatever
5. send all the data to my result page
   and display the result page.

Hope this gives you an idea to build on

First thank you for your insight and time.

I do not think I can use the meta tag option because I do not know how long the operation will take.

I tried the second option you mentioned before. The problem I have is between steps 2 and 3. Options I have tried, but failed at:

1. input form

2. check for valid input function

3. wait page

4. run query

5. input form

6. wait page

7. check for valid input

8. run query

None of which worked. I use header() to call the subsequent page, but it seems not matter what I do I see the input form, then wait, then I see the output. The only time I see the wait page is if I comment out the header() to run the query.

Do you have any other sugguestions? Does cache-control have anything to do with this problem?
