我正在构建一个脚本，从外部源创建新的博客帖子。我的代码如下：

    // Load WordPress
    require_once \'../../wp-load.php\';
    require_once ABSPATH . \'/wp-admin/includes/taxonomy.php\';
    // Set the timezone so times are calculated correctly
    date_default_timezone_set(\'Europe/London\');
    // Create post
    $id = wp_insert_post(array(
        \'post_title\'    => $headline,
        \'post_content\'  => $body,
        \'post_date\'     => date(\'Y-m-d H:i:s\'),
        \'post_author\'   => $user_id,
        \'post_type\'     => \'post\',
        \'post_status\'   => \'draft\',
    ));

if($id){
    // Set category - create if it doesn\'t exist yet
    wp_set_post_terms($id, wp_create_category($region), \'category\');
    // Add meta data, if required
    add_post_meta($id, \'meta_key\', $metadata);
    echo $open_wrap."<h2>Success!</h2>
    <p>The post has been added to the Bulletins Category as a <strong>draft</strong>.<br>
    Please $wp_url to Publish or Schedule the post.</p> 
    ".$close_wrap;

} else {
    echo "WARNING: Failed to insert post into WordPress\\n";
}

我想允许用户设置发布日期，这样他们就可以创建帖子，并在该日期自动发布。

是否有用于添加发布日期的wordpress功能？

wp_schedule_single_event( $timestamp, $hook, $args );

// Use this instead of wp_insert_post
wp_schedule_single_event( \'SET THE TIME HERE\', \'schedule_my_post\' );

// Add an action that runs the function
add_action( \'schedule_my_post\',\'publish_my_post\' );

// Now, do the actual publish
function publish_my_post($args){
    wp_insert_post($args);
}
