我正在网页上。以下代码在single.php中。
首先,如果有人打开了一个网页/后+ 1
<?php
//The cookie Besuche neeeds to be under 3
if (isset($_COOKIE['besuche'])){
if ($_COOKIE['besuche'] >= 3){
//If its more than 3, cookie resets to 1
$besuche_anz = 1;
$_COOKIE['besuche'] = $besuche_anz;
}else{
//If its less than 3. cookie + 1
$_COOKIE['besuche'] = $_COOKIE['besuche'] + 1;
$besuche_anz = $_COOKIE['besuche'];
}
}else{
//Cookie is not set
$besuche_anz = 1;
}
//write cookie "besuche"
setcookie("besuche", $besuche_anz, time() + (86400 * 30), "/");
//Here starts my problem... I want so write three cookies: cookie_id1, cookie_id2, cookie_id3. But all cookies should be diffrent. So they sould not have the same ID --> get_the_id()
$cookie_value = get_the_id();
setcookie("cookie_id".$besuche_anz, $cookie_value, time() + (86400 * 30), "/");
//Only if $cookie_value has the same ID --> Do nothing, else setcookie
if ($cookie_value == $_COOKIE["cookie_id1"]){}else{
setcookie("cookie_id".$besuche_anz, $cookie_value, time() + (86400 * 30), "/");
}
//Only if $cookie_value has the same ID --> Do nothing, else setcookie
if ($cookie_value == $_COOKIE["cookie_id1"] || $_COOKIE["cookie_id2"]){}else{
setcookie("cookie_id".$besuche_anz, $cookie_value, time() + (86400 * 30), "/");
}
get_header(); ?>
它为何不工作,我就指望每次?
目标是,从index.php(主页)上的Cookies中选择3个ID来选择最后查看的帖子。
如果我刷新一些帖子3次,我现在有3次同一篇文章在家里。
我在做什么错?
对'$ _COOKIE'的更改实际上并不改变cookie,你必须每次都执行'setcookie'。 – apokryfos
