Question

所以我有一个wp元查询处理搜索具有开始时间戳和结束时间戳的事件，我想返回用户在搜索中选择的两个日期内的所有结果。到目前为止，这部分工作正常。

但是，我想按开始时间戳对结果进行排序，因此最近的事件会先出现。

$args = array(
    's' => $_GET['k'],
    'post_type' => 'event',
    'posts_per_page' => '-1',
    'post_status' => array( 'private','publish' ),

    'meta_key' =>'_start_ts',
    'orderby' => 'meta_value_num',
    'order' => 'asc',

    'meta_query' => array(
        'relation' => 'OR',
        array(
            'key' => '_end_ts',
            'value' => array(strtotime($_GET['d1']),strtotime($_GET['d2'])),
            'compare' => 'BETWEEN',
            'type' => 'NUMERIC'
        ),
        array(
            'key' => '_start_ts',
            'value' => array(strtotime($_GET['d1']),strtotime($_GET['d2'])),
            'compare' => 'BETWEEN',
            'type' => 'NUMERIC'
        )
    )
);

如果我在4月份查看所有活动，我们会收到以下时间戳：

1397865600， 1398211200， 1398384000， 1397520000， 1398297600

我的数据库中有相同类型的事件。使用你的args并且查询执行得很漂亮。一个区别是我的日期来自数据库yyyymmdd值。我正在使用以这种格式保存的高级自定义字段插件。

这是我改编的代码

$args = array(
    's' => 'old',
    'post_type' => 'event',
    'posts_per_page' => '-1',
    'post_status' => array( 'private','publish' ),

    'meta_key' =>'start_date',
    'orderby' => 'meta_value_num',
    'order' => 'asc',

    'meta_query' => array(
        'relation' => 'OR',
        array(
            'key' => 'end_date',
            'value' => array(strtotime('20130101'),strtotime('20140101')),
            'compare' => 'BETWEEN',
            'type' => 'NUMERIC'
        ),
        array(
            'key' => 'start_date',
            'value' => array(strtotime('20130101'),strtotime('20140101')),
            'compare' => 'BETWEEN',
            'type' => 'NUMERIC'
        )
    )
);
$search = new WP_Query($args);

if ( $search->have_posts() ):

    setlocale(LC_ALL, 'nl_NL.UTF-8');

    while ( $search->have_posts() ) : $search->the_post();

        $start_date = get_post_meta(get_the_ID(), 'start_date', true);
        $end_date = get_post_meta(get_the_ID(), 'end_date', true);
        $start = strftime( '%A %e %B %Y', strtotime( $start_date ) );
        $end = strftime( '%A %e %B %Y', strtotime( $end_date ) );


        echo "$start ($start_date) - $end ($end_date) <br />";

    endwhile;
endif;

结果
