I have a basic form. but i want to...

[Monkuar]

Make it so the user can only use it once every x minutes or twice every 5minutes  or vice versa.. i looked on google for tutorials but i cant find anything and i got no clue it's out of my boundries of knowledge care to help me?

 

and it stores in the users cookie.. [i dont care if people can delete cookie] most wont and kinda need it to be stored in cookie.

The first time they submit the form store a timestamp in a cookie. Next time the form loads compare the timestamp from the cookie to the curent timestamp. If the difference is less than your time don't let them see the form.

Thanks for your post..

 

I dont understand any of that.. omg

[gevans]

Ok.....

 

 

<?php
$the_time_now = (time()+(60*5));
setcookie('form_submit', TRUE, $the_time_now, '/');

 

That will set a cookie on the users computer called form_submit that will expire in 5 minutes. When you load the form check for the cookie. If it exists, then that computer used the form within the last 5 mins.

But the user can just clear cookies to bypass that.

I know.. but the basics of deleting a cookie and re doing it again again takes time and it's fine.. holy cow man, lol

 

Ok Gevans Is that all i got? form_submit is the name?

 

wat about the else function and if? lol srry im really noob but ur helping me

[Ken2k7]

Takes time? Dude, I can clear domain cookies in less than 2 seconds. o.O

[Monkuar]

well it's better then nothing bro... if they wanted to spam something they would have less action of doing it if they had to delete cookies everytime right ? ya lol

[Ken2k7]

Or disable cookies. Then they won't have to delete anything. Though you can argue that only someone with intention to screw up your system would go for it. But it that one person succeeds, it can be very annoying.

[gevans]

Well, you've got the code to set the cookie, this is how you check if its still alive

 

<?php
if(isset($_COOKIE['form_submit']) && $_COOKIE['form_submit']) {
//cookies still there, they submitted the foirm within the last 5 mins
}
