我正在尝试创建一个查询，以仅提取未来事件。在客户端请求添加日期范围之前，它一直工作得很好，因此事件要么只有开始日期，要么有开始日期和结束日期。我需要构建一个查询，以提取将来有开始日期或结束日期的事件。这无法按预期工作，并会拉取所有事件；尽管将orderby设置为meta\\u值，但提取的顺序似乎是随机的。任何帮助都将不胜感激！

    function get_upcoming_events($num) {
    $today =  gmdate(\'Y-m-d\', time()-28800);

    $args = array(
        \'meta_key\'          => \'event_date\',
        \'order\'             => \'ASC\',
        \'orderby\'           => \'meta_value\',
        \'post_status\'       => \'publish\',
        \'posts_per_page\'    => $num,
        \'post_type\'         => \'events\',
        \'meta_query\' => array(
            \'relation\'=>\'OR\',
            array(
                \'key\' => \'event_date\',
                \'type\' => \'DATE\',
                \'value\' => $today,
                \'compare\' => \'>=\' 
            ),
            array(
                \'key\' => \'end_date\',
                \'type\' => \'DATE\',
                \'value\' => $today,
                \'compare\' => \'>=\' 
            )
        )
    );

    if ( isset( $data[ \'taxonomy\' ]) ) {
        $args[ \'tax_query\' ] = array();
        $args[ \'tax_query\' ][0] = array(
            \'field\'     => \'slug\',
            \'taxonomy\'  => \'event-type\',
            \'terms\'     => \'general\'
        );
    }
    $myquery = new WP_Query( $args );
    return $myquery;
    }
