我的Wordpress安装程序具有发布自定义post类型,并有10个自定义字段,每个字段对应于可能对该出版物作出贡献的作者。每个帖子可以有不同的作者在这些领域或相同的作者,但以不同的顺序。我正在使用Wordpress的WP_Query搜索符合我的标准的帖子。我需要对照所有的自定义字段检查一个作者的名字,看看它是否匹配其中的任何一个。我试着用下面的代码来做这件事,但是它没有产生任何结果。任何帮助都将不胜感激!
$args = array(
'post_type' => 'publication',
'post_status' => 'publish',
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'year_published',
'value' => $selected_pub_year,
'compare' => '=',
),
array(
'key' => array(
'author_0_name',
'author_1_name',
'author_2_name',
'author_3_name',
'author_4_name',
'author_5_name',
'author_6_name',
'author_7_name',
'author_8_name',
'author_9_name',
),
'value' => $selected_pub_author,
'compare' => '=',
),
),
);
// The above meta-query may be modified through the use of this:
// echo "<pre>".print_r($args[meta_query][relation])."</pre>";
// The Query
$the_query = new WP_Query($args);发布于 2015-12-31 05:46:00
我为post author查询添加了或relation,尝试更改参数数组如下:
$args = array(
'post_type' => 'publication',
'post_status' => 'publish',
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'year_published',
'value' => $selected_pub_year,
'compare' => '=',
),
array(
'relation' => 'OR',
array(
'key' => 'author_0_name',
'value' => $selected_pub_author,
'compare' => '=',
),
array(
'key' => 'author_1_name',
'value' => $selected_pub_author,
'compare' => '=',
),
array(
'key' => 'author_2_name',
'value' => $selected_pub_author,
'compare' => '=',
),
array(
'key' => 'author_3_name',
'value' => $selected_pub_author,
'compare' => '=',
),
array(
'key' => 'author_4_name',
'value' => $selected_pub_author,
'compare' => '=',
),
array(
'key' => 'author_5_name',
'value' => $selected_pub_author,
'compare' => '=',
),
array(
'key' => 'author_6_name',
'value' => $selected_pub_author,
'compare' => '=',
),
array(
'key' => 'author_7_name',
'value' => $selected_pub_author,
'compare' => '=',
),
array(
'key' => 'author_8_name',
'value' => $selected_pub_author,
'compare' => '=',
),
array(
'key' => 'author_9_name',
'value' => $selected_pub_author,
'compare' => '=',
),
),
),
);
$the_query = new WP_Query( $args );https://stackoverflow.com/questions/34541367
