[英]Writing query using WP_Query
I have 2 categories cat-slug1 and cat-slug2. 我有2类cat-slug1和cat-slug2。 Where, cat-slug1 is a parent of cat-slug2. 其中,cat-slug1是cat-slug2的父级。 I want to write a query wherein I want those results that belong to cat-slug1 and cat-slug2. 我想编写一个查询,其中我想要属于cat-slug1和cat-slug2的那些结果。
If one post is marked for cat-slug2 but not marked for cat-slug1 then I do not want to pick up this record in the results. 如果一个帖子被标记为cat-slug2但未标记为cat-slug1,那么我不想在结果中获得此记录。
How do I modify the code below so that it return me only those result which belong to cat-slug1 and cat-slug2 如何修改下面的代码,使其仅返回属于cat-slug1和cat-slug2的结果
$paged2 = isset( $_GET['paged2'] ) ? (int) $_GET['paged2'] : 1;
$args2 = array('abc_category' => 'cat-slug1',
'abc_category' => 'cat-slug2',
'post_type' => 'abc',
'paged' => $paged2,
'posts_per_page' => 20,
'orderby' => 'title',
'order' => 'asc');
$query2 = new WP_Query( $args2 );
What about making two queries? 进行两次查询怎么样?
$posts_cat1 = array(...)
$posts_cat2 = array(...)
$posts_cat1_and_cat2 = [];
foreach($posts_cat1 as $post){
if(in_array($post, $array_cat2)) array_push($posts_cat1_and_cat2, $post);
}
EDIT: 编辑:
Note that if you expect only posts to be fetched by WP_Query
you can replace it by get_posts
. 请注意,如果您希望WP_Query
仅获取帖子,则可以将其替换为get_posts
。 Here's a little update (untested): 这里有一些更新(未试用):
function get_posts_by_cat($cat){
$args = array('category'=>$cat);
return get_posts($args);
}
$posts_cat1 = get_posts_by_cat('cat-slug1');
$posts_cat2 = get_posts_by_cat('cat-slug2');
$posts_cat1_and_cat2 = [];
foreach($posts_cat1 as $post){
if(in_array($post, $array_cat2)) array_push($posts_cat1_and_cat2, $post);
}
