我正在尝试从以下查询中获取数据。如果等于 1，我希望通过第一个键和其他键值在两个日期之间得到结果，但查询仅为我返回今天的日期数据并在 sql 中添加OR关系。请帮助我找出错误并得到纠正。

我的代码是

 $curent_date = date('Y-m-d');
 $start_date = date('Y-m-d 00:00:01', strtotime($curent_date."- 4 day"));
 $end_date = date('Y-m-d 23:59:59', strtotime($curent_date."+ 4 day"));
$events_query = new WP_Query( array(
    'post_type' => array('tribe_events'),
    'post_status' => 'publish', 
    'meta_key' => '_EventStartDate',
    'orderby'   => 'meta_value',
    'order'     => 'DESC',
    'meta_query' => array( 
        'relation' => 'AND',
        array(
        'key' => '_EventStartDate',
        'value' => array( $start_date, $end_date ),
        'compare' => 'BETWEEN'
    ),
    array(
        'key' => 'agenda',
        'value' => 1,
        'compare' => '='
    ),
    ),) );
 print_r($events_query->request);

 print_r($events_query->posts);

返回 SQL 是

SELECT SQL_CALC_FOUND_ROWS DISTINCT wp_posts.*, MIN(wp_postmeta.meta_value) as EventStartDate, MIN(tribe_event_end_date.meta_value) as EventEndDate FROM wp_posts  INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id )  INNER JOIN wp_postmeta AS mt1 ON ( wp_posts.ID = mt1.post_id )  INNER JOIN wp_postmeta AS mt2 ON ( wp_posts.ID = mt2.post_id )  INNER JOIN wp_postmeta AS mt3 ON ( wp_posts.ID = mt3.post_id ) LEFT JOIN wp_postmeta as tribe_event_end_date ON ( wp_posts.ID = tribe_event_end_date.post_id AND tribe_event_end_date.meta_key = '_EventEndDate' )  WHERE 1=1  AND ( 
  wp_postmeta.meta_key = '_EventStartDate' 
  AND 
  ( 
    mt1.meta_key = '_EventStartDate' 
    AND 
    ( mt2.meta_key = '_EventStartDate' AND mt2.meta_value BETWEEN '2017-05-22 00:00:01' AND '2017-05-30 23:59:59' ) 
    AND 
    ( mt3.meta_key = 'agenda' AND mt3.meta_value = '1' )
  )
) AND wp_posts.post_type = 'tribe_events' AND ((wp_posts.post_status = 'publish')) AND **(wp_postmeta.meta_value >= '2017-05-26 02:58:14' OR (wp_postmeta.meta_value <= '2017-05-26 02:58:14' AND tribe_event_end_date.meta_value >= '2017-05-26 02:58:14' )) GROUP BY wp_posts.ID ORDER BY EventStartDate DESC, wp_postmeta.meta_value DESC LIMIT 0, 10

提前致谢。

比较 wp_query 中的日期时间，您需要将日期的元查询项转换为DATE OrDATETIME`。

$events_query = new WP_Query( array(
'post_type' => array('tribe_events'),
'post_status' => 'publish', 
'meta_key' => '_EventStartDate',
'orderby'   => 'meta_value',
'order'     => 'DESC',
'meta_query' => array( 
    'relation' => 'AND',
    array(
    'key' => '_EventStartDate',
    'value' => array( $start_date, $end_date ),
    'compare' => 'BETWEEN',
    'type'=>'DATE'
),
array(
    'key' => 'agenda',
    'value' => 1,
    'compare' => '='
),
),) );

如果这不起作用，您可以尝试此代码

$events_query = new WP_Query( array(
'post_type' => array('tribe_events'),
'post_status' => 'publish', 
'meta_key' => '_EventStartDate',
'orderby'   => 'meta_value',
'order'     => 'DESC',
'meta_query' => array( 
    'relation' => 'AND',
    array(
           'key' => '_EventStartDate',
           'value' => $start_date,
           'compare' => '<=',
           'type' => 'DATE'
       ),
array(
           'key' => '_EventEndDate',
           'value' => $end_date,
           'compare' => '>=',
           'type' => 'DATE'
       )
array(
    'key' => 'agenda',
    'value' => 1,
    'compare' => '='
),
),) );
