如何使用 WP Post 状态转换来处理帖子到期日期
How to use WP Post Status Transitions to handle posts expiration dates
我是新手,date/time/PHP 这件事让我脑袋疼。
1) 如何使用 WP Post Status Transitions 注册 post 状态更改的确切日期和时间(我们将其命名为 valueX)?
2) 现在我从我的主题选项中带来其他价值 (valueY) - 它要么是一个时期(例如 30 天)要么日期和时间
3)如何用valueX和valueY计算得到valueZ -> 这是 post 更改为草稿或删除自身的日期和时间!
这最终应该如何工作:
- 我在主题选项中有 2 个输入,1 个用于 draft lifespawn,1 个用于发布 post lifespawn(输入为整数 - 值为分钟或小时)
- 如果您发布 post,它会保存该事件的日期和时间。
- 将主题选项值(已发布 post lifespawn int)添加到该时间,结果是 post 更改为草稿
的日期
- 如果那个时候到了,将 post 更改为草稿(并节省那个时间)
- 将主题选项值(draft lifespawn int)添加到那个时间,结果是 draft 被删除的日期
- 到时候删除草稿
听起来很合乎逻辑,但我没有足够的技能来做到这一点。
我的代码:
注意:
- 为了便于阅读,我将其分为两部分 - 第一部分已发布 post 草稿,第二部分代码是
要删除的草稿。每一步都有注释。
- 逻辑是,如果您编辑已发布的 post,它不应该重置计时器
如果你在任何给定时间将 post 更改为草稿,它就会开始草稿
进程并停止发布 post 进程。
- 这似乎太长太复杂了..这就是为什么我没有
首先添加它。我相信它可以更容易地完成
方式。
- 我用了WP post time和edit time因为不知道怎么节省时间
& 该特定时间的日期使用 WP Post Status Transitions.

1) How to use WP Post Status Transitions to register exact date & time
of post status change (let's name it valueX)?
在我看来,处理此问题的更好方法不是使用 Post 转换状态挂钩,而是使用 Wordpress Cron - 因为当管理员更改 [=62] 时挂钩将被调用=]状态。我们将只使用一个 Post 转换状态来注册 首次 post 已在名为 firstPublishTime
的自定义字段中发布:
add_action('transition_post_status', 'first_publish_time_register', 10, 3);
function first_publish_time_register($new, $old, $post) {
if ($new == 'publish' && $old != 'publish' && $post->post_type == 'post') { // change this to whatever post type you like
$firstPublishTime = get_post_meta($post->ID, 'firstPublishTime', true);
if(empty($firstPublishTime)) {
// First time the post is publish, register the time
add_post_meta($post->ID, 'firstPublishTime', strftime('%F %T'), true);
}
}
}
2) Now I bring other value from my theme options (valueY) - it's
either a period (e.g 30 days) or date & time
对于下一部分,我将考虑您有两个主题选项,两个时期:一个用于名为 your_theme_option1
的 "publish to draft" 延迟,另一个用于名为 "draft to deleted delay" 的延迟 your_theme_option2
;采用 YY-MM-DD-HH-MM-SS
格式。例如 00-00-30-00-00-00
表示 30 天,00-01-00-00-00-00
一个月等
3) How to make a calculation with valueX and valueY to get valueZ ->
that's date & time when post deletes itself!
这就是乐趣所在。我们将注册一个每小时执行一次的 WP Cron(请注意,它不是服务器 cron,如果没有人在一小时内访问您的网站,将不会被处理 )。
以下代码将每小时执行一次 cron_postStatus()
函数:
register_activation_hook(__FILE__, 'cron_postStatus_activation');
add_action('postStatus_event', 'cron_postStatus');
function cron_postStatus_activation() {
wp_schedule_event(time(), 'hourly', 'postStatus_event');
}
现在重要的是:
function cron_postStatus() {
// Get the theme options
$published_to_draft_delay = get_option('your_theme_option1');
$draft_to_deleted_delay = get_option('your_theme_option2');
if(!$published_to_draft_delay || !$draft_to_deleted_delay) {
return new WP_Error('broke', __('Theme options unavailable'));
}
$published_to_draft_delay = explode('-', $published_to_draft_delay);
$draft_to_deleted_delay = explode('-', $draft_to_deleted_delay);
$published_to_draft_delay = new DateInterval(
'P'.$published_to_draft_delay[0].'Y'.
$published_to_draft_delay[1].'M'.
$published_to_draft_delay[2].'D'.
'T'.$published_to_draft_delay[3].'H'.
$published_to_draft_delay[4].'M'.
$published_to_draft_delay[5].'S'
);
$draft_to_deleted_delay = new DateInterval(
'P'.$draft_to_deleted_delay[0].'Y'.
$draft_to_deleted_delay[1].'M'.
$draft_to_deleted_delay[2].'D'.
'T'.$draft_to_deleted_delay[3].'H'.
$draft_to_deleted_delay[4].'M'.
$draft_to_deleted_delay[5].'S'
);
$now = new DateTime();
// Get all the unpublished posts
$unpublished_posts = new WP_Query(array(
'posts_per_page' => -1,
'post_type' => 'post', // change this to whatever post type you like
'meta_key' => 'expirationDate',
'post_status' => 'draft'
));
while($unpublished_posts->have_posts()) {
$unpublished_posts->the_post();
$expirationDate = get_post_meta(get_the_ID(), 'expirationDate', true);
if(!empty($expirationDate)) {
// Date comparison
$dt = new DateTime($expirationDate);
$dt->add($draft_to_deleted_delay);
if($dt > $now) {
// Expiration date reached, unpublish the post
wp_delete_post(get_the_ID(), true);
}
}
}
// Get all the published posts
$published_posts = new WP_Query(array(
'posts_per_page' => -1,
'post_type' => 'post', // change this to whatever post type you like
'meta_key' => 'firstPublishTime'
));
while($published_posts->have_posts()) {
$published_posts->the_post();
$first_publish = get_post_meta(get_the_ID(), 'firstPublishTime', true);
if(!empty($first_publish)) {
// Date comparison
$dt = new DateTime($first_publish);
$dt->add($published_to_draft_delay);
if($dt > $now) {
// Expiration date reached, unpublish the post
wp_transition_post_status('draft', 'publish', $published_posts->post);
add_post_meta($post->ID, 'expirationDate', strftime('%F %T'), true);
}
}
}
wp_reset_postdata();
}
在这里我决定使用 DateInterval
以便轻松地操纵到期日期。首先,我们从 wp_options
获取到期日期选项,将它们构建在 DateInterval
对象中,然后获取当前时间。然后我们将进行两次查询,一次查询草稿,一次查询已发布的 posts。对于草稿,我们检查是否有 expirationDate
元值,如果有并且我们到了删除时间,我们从数据库中删除 post。对于已发布的 post,如果我们到了到期日期,我们会将状态更改为草稿,并添加一个名为 expirationDate
的自定义值 - 这是为了区分 "publish to draft" 更改cron 和管理的变化。
请注意,这是未经测试的代码
更新
这里有一个函数,您可以使用它来根据要求获取剩余到期时间:
function getExpirationInfos($post) {
// Get all informations
$first_publish = get_post_meta($post->ID, 'firstPublishTime', true);
$expirationDate = get_post_meta($post->ID, 'expirationDate', true);
if(empty($first_publish)) {
return '';
}
$published_to_draft_delay = get_option('your_theme_option1');
$draft_to_deleted_delay = get_option('your_theme_option2')
$published_to_draft_delay = explode('-', $published_to_draft_delay);
$draft_to_deleted_delay = explode('-', $draft_to_deleted_delay);
$published_to_draft_delay = new DateInterval(
'P'.$published_to_draft_delay[0].'Y'.
$published_to_draft_delay[1].'M'.
$published_to_draft_delay[2].'D'.
'T'.$published_to_draft_delay[3].'H'.
$published_to_draft_delay[4].'M'.
$published_to_draft_delay[5].'S'
);
$draft_to_deleted_delay = new DateInterval(
'P'.$draft_to_deleted_delay[0].'Y'.
$draft_to_deleted_delay[1].'M'.
$draft_to_deleted_delay[2].'D'.
'T'.$draft_to_deleted_delay[3].'H'.
$draft_to_deleted_delay[4].'M'.
$draft_to_deleted_delay[5].'S'
);
$now = new DateTime();
// Calculate time left
if($post->post_status == 'publish') {
$dt = new DateTime($first_publish);
$dt->add($published_to_draft_delay);
} else {
if(empty($expirationDate)) {
return '';
}
$dt = new DateTime($expirationDate);
$dt->add($draft_to_deleted_delay);
}
$et = date_diff($dt, $now);
$expirationTimeString = (($et->y > 0) ? $et->format('y') . ' years, ' : '') .
(($et->m > 0) ? $et->format('y') . ' months, ' : '') .
(($et->d > 0) ? $et->format('m') . ' days, ' : '') .
(($et->h > 0) ? $et->format('h') . ' hours, ' : '') .
(($et->i > 0) ? $et->format('i') . ' minutes, ' : '') .
(($et->s > 0) ? $et->format('s') . ' seconds, ' : '');
$expirationTimeString = substr($expirationTimeString, 0, -2);
// Return HTML
return '<i class="fa fa-clock-o" data-toggle="tooltip" title="' . __( 'Property gets deleted on', 'tt' ) . ' ' . $expirationTimeString . '"></i>';
}
然后在您的模板中执行 echo getExpirationInfos($post);
以显示到期日期。
