問題描述
我有一個自定義的帖子類型”Listing”,我想得到所有具有自定義字段 gateway_value != 'Yes'的列表,並通過另一個自定義字段 location_level1_value 排序結果。我可以讓查詢單獨工作,但是我不能組合它們:
查詢 1(按位置排序):
$wp_query = new WP_Query( array (
'post_type' => 'listing',
'post_status' => 'publish',
'posts_per_page' => '9',
'meta_key' => 'location_level1_value',
'orderby' => 'location_level1_value',
'order' => 'ASC',
'paged' => $paged
)
);
查詢 2(自定義字段值!=是):
$wp_query = new WP_Query( array (
'post_type' => 'listing',
'posts_per_page' => '9',
'post_status' => 'publish',
'meta_key' => 'gateway_value',
'meta_value' => 'Yes',
'meta_compare' => '!=',
'paged' => $paged
)
);
組合查詢:
我查看了 codex 以獲取幫助,但以下查詢不起作用:
$wp_query = new WP_Query( array (
'post_type' => 'listing',
'posts_per_page' => '9',
'post_status' => 'publish',
'meta_query' => array(
array(
'key' => 'gateway_value',
'value' => 'Yes',
'compare' => '!='
),
array(
'key' => 'location_level1_value'
)
),
'orderby' => "location_level1_value",
'order' => 'ASC',
'paged' => $paged
)
);
我在組合查詢中做錯了什麼?
[更新]:現在 3.1 已經發布,上面的組合查詢仍然不起作用。我得到的結果,只是沒有排序正確。
[更新]:var_dump($wp_query->request)給出以下內容:string(527) " SELECT SQL_CALC_FOUND_ROWS wp_7v1oev_posts.* FROM wp_7v1oev_posts
INNER JOIN wp_7v1oev_postmeta ON (wp_7v1oev_posts.ID = wp_7v1oev_postmeta.post_id)
INNER JOIN wp_7v1oev_postmeta AS mt1 ON (wp_7v1oev_posts.ID = mt1.post_id) WHERE 1=1 AND wp_7v1oev_posts.post_type = 'listing' AND (wp_7v1oev_posts.post_status = 'publish') AND wp_7v1oev_postmeta.meta_key = 'gateway_value' AND CAST(wp_7v1oev_postmeta.meta_value AS CHAR) != 'Yes' AND mt1.meta_key = 'location_level1_value' ORDER BY wp_7v1oev_posts.post_date DESC LIMIT 0, 9"
最佳解決方案
您可以使用查詢通過使用具有過濾選項的’meta_query’ 按預期過濾內容,對於訂單部分,只需添加/修改以下參數:
-
‘orderby’ => ‘meta_value’
-
‘meta_key’ => ‘location_level1_value’
-
‘order’ => ‘ASC’
$wp_query = new WP_Query( array ( 'post_type' => 'listing', 'posts_per_page' => '9', 'post_status' => 'publish', 'meta_query' => array( array( 'key' => 'gateway_value', 'value' => 'Yes', 'compare' => '!=' ) ), 'orderby' => 'meta_value', // this means we will be using a selected // meta field to order 'meta_key' => 'location_level1_value', // this states which meta field // will be used in the ordering, // regardless of the filters 'order' => 'ASC', 'paged' => $paged ) );
