Action link

[Mark Towner]

Greetings,

Does anyone have a solution for this problem:

- I would like a PHP script to execute an action before a user clicks
on a link (updating the value of a variable, for instance).

Is there an easy way to do this?

Thanks,
Mark

What do you mean? A PHP script is only executed when it is told to so by
eihter Apache (via the user), a cron job, or some other method.

What are you trying to accomplish? If you want to just update a variable,
put it at the top of the script.

A few:
- Just put it at the top of the script
- Cron jobs (scheduled tasks)
- Ajax/JS

Mark,

If I understand your question correctly, no, you can't do anything before the
user clicks on a link. PHP is server-side only, and nothing happens until the
user does something to request the page.

It sounds like you need something client-side, like javascript.
