Exclude posts from get_posts()
提问by Marco
Good morning, I found many similar questions, but none of the answer fit to my problem. The point is very simple: I have a custom loop with get_posts(), and I want to exclude current post from being displayed.
早上好，我发现了很多类似的问题，但没有一个答案适合我的问题。重点很简单：我有一个带有 get_posts() 的自定义循环，我想从显示中排除当前帖子。
The code is:
代码是：
$args = array(
'posts_per_page' => 3,
'orderby' => 'meta_value',
'order' => 'ASC',
'post_type' => 'fasthomepress_pt',
'post__not_in' => array(get_the_id()),
'meta_query' => array(
array(
'key' => 'custom_richiesta',
'value' => array($custom_boxes['custom_richiesta'][0] - 10000, $custom_boxes['custom_richiesta'][0] + 10000 ),
'type' => 'numeric',
'compare' => 'BETWEEN'
)
)
);
I tried with:
我试过：
'post__not_in' => array(get_the_ID),
'post__not_in' => array($post->ID),
'exclude' => $post->ID,
'exclude' => get_the_ID,
and with many other combinations with or without array. Of curse, current post id is correctly echoed before this loop, and if I try echo($post->ID) and echo(get_the_ID()) I have the same, correct, result.
以及许多其他带有或不带有数组的组合。诅咒，当前帖子 ID 在此循环之前正确回显，如果我尝试 echo($post->ID) 和 echo(get_the_ID()) 我有相同的、正确的结果。
I really don't know what's happening, thank you very much for help,
我真的不知道发生了什么，非常感谢您的帮助，

Try exclude.
试试exclude。
$args = array(
'posts_per_page' => 3,
'orderby' => 'meta_value',
'order' => 'ASC',
'post_type' => 'fasthomepress_pt',
'exclude' => array(get_the_id()),
'meta_query' => array(
array(
'key' => 'custom_richiesta',
'value' => array($custom_boxes['custom_richiesta'][0] - 10000, $custom_boxes['custom_richiesta'][0] + 10000 ),
'type' => 'numeric',
'compare' => 'BETWEEN'
)
)
);

here is a function that does just that:
这是一个可以做到这一点的函数：
function get_lastest_post_of_category($cat){
$args = array( 'posts_per_page' => 1, 'order'=> 'DESC', 'orderby' => 'date', 'category__in' => (array)$cat);
$post_is = get_posts( $args );
return $post_is[0]->ID;
}
Usage: say my category id is 22 then:
用法：假设我的类别 ID 为 22，然后：
$last_post_ID = get_lastest_post_of_category(22);
you can also pass an array of categories to this function.
您还可以将类别数组传递给此函数。
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
'posts_per_page' => 18,
'paged' => $paged,
'offset' => 0,
'post__not_in' => array($last_post_ID,),
'category' => '',
'category_name' => '',
'orderby' => 'post_date',
'order' => 'DESC',
'include' => '',
'exclude' => '',
'meta_key' => '',
'meta_value' => '',
'post_type' => 'post',
'post_mime_type' => '',
'post_parent' => '',
'post_status' => 'publish',
'suppress_filters' => true
);
// The Query
$the_query = new WP_Query( $args );
