[英]Wordpress: Different options per post type in WP_Query
I have two post types (type-A and type-B) and two taxonomies (tax-1 and tax-2), both assigned to each post type.我有两种帖子类型(A 类和 B 类)和两个分类法(tax-1 和 tax-2),它们都分配给每个帖子类型。 This means that posts from type-A can contain terms from tax-1 and tax-2 and posts from type-B can also contain terms from tax-1 and tax-2.
这意味着类型 A 的帖子可以包含来自 tax-1 和 tax-2 的条款,来自类型 B 的帖子也可以包含来自 tax-1 和 tax-2 的条款。
I want my WP_Query to output all posts from type-A that contain certain terms of tax-1.我希望我的 WP_Query 输出来自类型 A 的所有帖子,其中包含特定的 tax-1 条款。 But I don't want to output type-B posts that contain these tax-1 terms, which my WP_Query unfortunately does.
但我不想输出包含这些 tax-1 条款的 B 类帖子,不幸的是我的 WP_Query 这样做了。 The same should apply to tax-2, whereby only posts from type-B that contain terms from tax-2 should be output.
这同样适用于 tax-2,即只输出包含 tax-2 条款的 B 类帖子。
I have already tried to create two $args for this, but I did not manage to merge the two $args.我已经尝试为此创建两个 $args,但我没有设法合并这两个 $args。
function my_function($args) {
global $post;
$args = array(
'post_type' => array('type-A','type-B'),
'tax_query' => array(
'relation' => 'OR',
array(
'taxonomy' => 'tax-1',
'field' => 'term_id',
'terms' => array(11, 12, 13),
),
array(
'taxonomy' => 'tax-2',
'field' => 'term_id',
'terms' => array(21, 22, 23),
),
),
);
return $args;
}
I have now found a solution myself, which I would like to share here.我现在自己找到了一个解决方案,我想在这里分享。
The idea is to create a query for each of the two post types.这个想法是为两种帖子类型中的每一种创建一个查询。 For each post type I will get the result in a list with the post IDs using
wp_list_pluck()
.对于每种帖子类型,我将使用
wp_list_pluck()
在带有帖子 ID 的列表中获得结果。 With array_merge()
I merge the lists into one, which can be included in a final query with post__in
.使用
array_merge()
将列表合并为一个,可以使用post__in
将其包含在最终查询中。
function my_function($query_args) {
global $post;
$query_args_1 = new WP_Query(array(
'post_type' => array('type_A'),
'tax_query' => array(
'relation' => 'OR',
array(
'taxonomy' => 'tax_1',
'field' => 'term_id',
'terms' => array(11, 12, 13),
),
),
));
$list_id_1 = wp_list_pluck( $query_args_1->posts, 'ID' );
$query_args_2 = new WP_Query(array(
'post_type' => array('type_B'),
'tax_query' => array(
'relation' => 'OR',
array(
'taxonomy' => 'tax_2',
'field' => 'term_id',
'terms' => array(21, 22, 23),
),
),
));
$list_id_2 = wp_list_pluck( $query_args_2->posts, 'ID' );
$merged_list = array_merge($list_id_1, $list_id_2);
$query_args = array(
'post_type' => array('type_A', 'type_B'),
'orderby' => 'relevance',
'order' => 'ASC',
'post__in' => $merged_list
);
return $query_args;
}
