Simple php cookie script. Visitors are asked to accept the placement of cookes. When they do a different message/ad/tracking/social will be active.

Cookie parameters and placing, place somewhere at top of code.

/****************************************

 * cookiespolicy stuff
 *
 */

// parameters
$cookie_name  = "mywebsite-com"; // websitename-tld
$cookie_value = "accepted";

// set cookie is user clicks accept button
if (isset($_POST['gotit'])) {
    setcookie($cookie_name, $cookie_value, time() + (86400 * 30), "/"); // 86400 seconds = 1 day
    $setcookie = 1;
} else {
    $setcookie = false;
}

Info and accept button, place in webpage header.

/****************************************
 *
 * cookie accept form, mostly on top of screen
 *
 */

if ($setcookie == false && !isset($_COOKIE[$cookie_name])) {

    // cookies not enabled, show message
    echo '<aside>
        <p>Sorry for this dumb message. We're using cookies on this site in order to know a bit about our visitors, where they come from and how many are seeing this site. Also we show an advertisement on this webpage. To make this possible we use <a href="link-to-cookie-policy.php">cookies</a>. 
        <form action="#" method="post"><button type="submit" name="gotit" value="gotit">Got it.</button></form>
        </p>
    </aside>';
}

Show no-cookies message or show part when cookies are accepted. Can be placed anywhere in code or html.

/****************************************
 *
 * if cookie is accepted show ad, social, ...
 * else show message
 *
 */

if ($setcookie == false && !isset($_COOKIE[$cookie_name])) {

	// cookies not enabled, show message
	echo '<p>Oh dear, no cookies are set.</p>';
