How to process items that "happen" farther down in the code.

[erikcw]

Hi,

I have a function that counts the number of lines in a textarea/variable. (\n)
The function is executed at the top of the webpage, but the textarea where the processing takes place is a couple of hundred lines later.

Because of this the counter is always behind. It catches up onces the form is POSTed to the next step.

Is threr a way to process the results of a function that happens later - some sort of pause perhaps?

Thanks!

couldn't you just move the function to the bottom of the code?
if you want to pause the command is
sleep(number of seconds);
i don't think this is what you need though
perhaps yo ucould provide an example

If you want immediate feedback from the contents of a textarea, you might be seeking a javascript solution, not a PHP function.

yes, more detail is needed

Like httpwebwitch said, you need to use javascript. Once a php script returns the results, there is no way to interact with it (unless by posting the form again). That's why you need a client side script.
