I need help with cookies

Hy

Can anyone tell me how to specific <div> to show only once per user in 24 hours?

I use wordpress themes, and want to show specific ad only once per user in 24 hours.

Also I would like to know how to restart cookies for that <div>.

Thanks in advance

You can use the PHP function setcookie with expire parameter as time()+60*60*24 == 24 hours, so the cookie would automatically expire in 24 hours.

Check with $_COOKIE['unique-identifier'] if the cookie exists and if so don't display the div

I like the localstorage one more as it is supported by all modern browsers and does not depend on cookie..

Code:

if(localStorage.last){
    if( (localStorage.last - Date.now() ) / (1000*60*60*24) >= 1){ //Date.now() is in milliseconds, so convert it all to days, and if it's more than 1 day, show the div
        document.getElementById('div').style.display = 'block'; //Show the div
        localStorage.last = Date.now(); //Reset your timer
    }
}
else {
    localStorage.last = Date.now();
    document.getElementById('div').style.display = 'block'; //Show the div because you haven't ever shown it before.
}

You are welcome. Be sure to catch the exeption and use cookie if you are using localStorage. That way, you prepare for the dinosaur browsers too

Why would you want to show ads to users per 24 hours?

I'm sorry but I don't want to share answer.

perhaps the ad was bought only to be shown once for every unique visitor, this is option all the ad networks give.
