Automatic detection of first visitor to page

Copy linkTweet thisAlerts:
Jun 09.2009

Hi,
I made a site with prize for a visitor who first clicks on one link. Now I must write the actuall page for that link. ? When user clicks on link it should open a page with form for sending some information(name, e-mail). When someone opens that page it should be disabled for others. But if first person leaves it without submiting required informations than it should be reenabled again. Is it possible to do it in PHP? I think that posting links is forbidden, so can’t write it here, but if someone didn’t understand me- the site is in my profile(FAQ). ?
Thanks!

@jacjil2Jun 10.2009 — If you only need to store one winning record. Something like
[code=php]
if(isset($_POST['name']) && isset($_POST['email']) && !file_exists("winner.txt")){
$record = "name=".$_POST['name']." email=".$_POST['email'];
put_file_contents("winner.txt", $record);
}[/code]

This may be grossly over-simple, but I'm not sure what you are running here.

@EldoradoauthorJun 10.2009 — Thank you! But I think this code shows page to everyone until someone fills the form? I would like to hide it after first visitor opens it. (To avoid congratulating to the wrong person. ? ) Maybe current time could be stored in a cookie and (if_cookie != that_time) show another page? If that person leaves the page than enable it again. ?

Success!
