我试图弄清楚为什么这段代码没有传递提交时隐藏输入字段的值。
代码取自WordPress模板页面，我已将其从所有特征WP标签中剥离，以便将其粘贴到此处。字段ID是“cutoff”。
<?php
$cutoffdate = $_POST['cutoff'];
$school = empty($_COOKIE['school']) ? null : $_COOKIE['school'];
$department = empty($_COOKIE['department']) ? null : $_COOKIE['department'];
if ( ! empty($_POST['school']) ) {
setcookie('school', $_POST['school'], time() + 3600 * 24 * 30, '/');
setcookie('department', @$_POST['department'], time() + 3600 * 24 * 30, '/');
header('Location: '. $_SERVER['REQUEST_URI']);
exit;
}
if ( ! $school) {
/*some code here */ }
elseif ($cutoffdate == "1") {
?>

我可能遗漏了一些基本或明显的东西，但我只是看不出为什么这不起作用......
答案 0 :(得分：0)
是的，我弄清楚出了什么问题：
if ( ! empty($_POST['school']) ) {
setcookie('school', $_POST['school'], time() + 3600 * 24 * 30, '/');
setcookie('department', @$_POST['department'], time() + 3600 * 24 * 30, '/');
header('Location: '. $_SERVER['REQUEST_URI']);
exit;
}
此处的标头功能是重定向并终止$ _POST值。虽然我不能说100％它是标题本身而不是te退出这一切都搞砸了。如果知道更多的人可以解释，我会很高兴...
