用PHP和WordPress比较时间

Question

我试图创建一个插件来比较一段信息的时间。在WordPress数据库到当前时间。例如，如果该帖子在5/6在12:00 pm过期，则在该时间之前它不会显示过期的标签。

日期和时间表达式采用以下格式：MM/DD/YYYY HH：MM（军事时间）。 以下是我到目前为止的PHP代码。有人可以看看我的代码，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; 
}} 

Answer 1

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; 
}
