对这段javascript和php cookie代码有问题
提问于 2018-10-23 04:45:32
这是我正在尝试做的:使用php和javascript创建一个cookie onclick。我使用的代码(下面)不起作用，因为我真的不知道我在做什么。我需要它在我的域中使用，并在五分钟内过期。有人能帮我改正这段代码吗？谢谢。
<?php
// name of the cookie
$cookie_name = 'testcookie';
// expires in five minutes, also the value of the cookie
$cookie_expire_time = time() + 300;
// check if cookie is set
if(!isset($_COOKIE[$cookie_name])) {
// if NOT set
echo 'Cookie is NOT set. <a href="https://MyTestPage.com/" onClick="window.open(\'https://google.com/\'); setCookie(\''.$cookie_name.'\', \''.$cookie_expire_time.'\', '.$cookie_expire-time.');">Click here to set the cookie, reload the page, and open google in a new tab.</a>';
} else {
// if IS set
echo 'Cookie IS set now.';
}
echo '<script>
function setCookie(cname, cvalue, exdays) {
var expires = "expires="'.$cookie_expire_time.';
document.cookie = cname + "=" + cvalue + "; " + expires;
}
</script>';
?>我最初的测试片段工作正常(如下所示)，只是不能获得第一个示例来工作，这个示例是如何工作的。这张30天后过期。如何使用PHP在几分钟内传递过期时间？
<?php
$cookie_name = 'testcookie2';
if(!isset($_COOKIE[$cookie_name])) {
echo 'Cookie is NOT set. <a href="https://MyTestPage.com/" onClick="window.open(\'https://google.com/\'); setCookie(\'testcookie2\', \'yes\', 30);">Click here to set the cookie, reload the page, and open google in a new tab.</a>';
} else {
echo 'Cookie IS set now.';
}
echo '<script>
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*24*60*60*1000));
var expires = "expires="+d.toUTCString();
document.cookie = cname + "=" + cvalue + "; " + expires;
}
</script>';

无论如何，谢谢大家。我只做了几处改动就让代码按原样工作。虽然是"hackey"，但还是照我说的做。下面是我使用的代码：
<?php
$cookie_name = 'testcookie5';
$cookie_time = '1';
if(!isset($_COOKIE[$cookie_name])) {
echo 'Cookie is NOT set. <a href="https://MyTestPage.com/" onClick="window.open(\'https://google.com/\'); setCookie(\'testcookie5\', \'\', '.$cookie_time.');">Click here to set the cookie, reload the page, and open google in a new tab.</a>';
} else {
echo 'Cookie IS set now. Value is: '.strtotime($_COOKIE[$cookie_name]).'<br />';
}
echo '<script>
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*60*1000));
var expires = "expires="+d.toUTCString();
var cevalue = d.toUTCString();
document.cookie = cname + "=" + cevalue + "; " + expires;
}
</script>';
