Voting, how can I make it possible to vote once?

Question

Kohana

Hello, I found the following line in the voting module:

if (isset($exists->id) && (time() - strtotime($exists->date)) < 60 * 60 * 24) {

As I understand it, she is responsible for the voting date, it seems like a day or two passes and you can vote on a new one, how to make it possible to vote once, what numbers to write down?

Answer 1

Используй $_COOKIE

Answer 2

in your example it is exactly 24 hours.
It depends how you want to implement it. If you look at the rough side, then just change the parameter 60 * 60 * 24 to 60 * 60 * 24 * 31, then users will not be able to vote for a month :-)
But this is bad, because the poll can change.
Use cookies as described above, but make the cookie name prefixed with the survey ID. For example vote_101, then check it.
