我正在尝试创建一个插件来比较一条信息的时间。在 WordPress 数据库中到当前时间。例如，如果帖子在 5 月 6 日下午 12:00 过期，则在此之前它不会显示过期标签。

日期和时间表达式采用以下格式：MM/DD/YYYY HH:MM（军用时间）。到目前为止，这是我所拥有的 PHP 代码。有人可以查看我的代码，看看我是否做错了什么？请？:)

global $post;
$expired_post = get_post_meta( $post->ID, 'deal_exp_dt', true);
$expired_post_time = strtotime($expired_post);

// CONTENT FILTER
add_filter( 'the_content', 'my_the_content_filter', 20 );
function my_the_content_filter( $content ) {
if(time() > $expired_post_time && !empty($expired_post)) {
    $content = sprintf(
        '<div id="expired_deal_post"><strong><span style="font-size: x-large;">EXPIRED</span></strong><br><span style="font-size: medium;">This deal has ended.</span></div>%s',
        $content
    );

// Returns the content.
return $content;
}}

function my_the_content_filter( $content ) {

// these two variables should reside this function scope, otherwise declare them as global

$expired_post = get_post_meta( $post->ID, 'deal_exp_dt', true);
$expired_post_time = strtotime($expired_post);



if(time() > $expired_post_time && !empty($expired_post)) {
    $content = sprintf(
        '<div id="expired_deal_post"><strong><span style="font-size: x-large;">EXPIRED</span></strong><br><span style="font-size: medium;">This deal has ended.</span></div>%s',
        $content
    );
 }

// Returns the content.
return $content;
}
