我不是通过使用元查询方法而是实际上通过使用 2 个查询来实现这一点，我认为这是不可能的。我会尽力为可能遇到相同问题的其他人解释。
此解决方案将帮助人们尝试解决问题
- 带有固定或粘性帖子的 AJAX 分页
- 具有自定义帖子类型的置顶帖子
可以在这里找到无注释版本https://github.com/Sandy-Garrido/wordpress-ajax-pagination-sticky-pinned
Pre-req - 为固定/粘性设置元数据
我假设您已经（使用 ACF 或其他方式）设置元数据来检索置顶帖子。在我的示例中，我有一个名为 set_as_pinned 的键的布尔字段类型
第 1 步 - 获取您的置顶/粘贴帖子
$paged = $_POST['pageRequested'];
// declare an empty array for your pinned posts
// (this helps us exclude it from our query when we need to get all the other posts)
$pinned_post_arr = array();
// Define your args for pinned or sticky posts
$pinned_args = array(
'post_type' => 'insight',
'posts_per_page' => -1,
'meta_key' => 'set_as_pinned',
'meta_value' => true
);
// Query list of pinned posts using wp_query or get_posts()
$pinned_posts = new \WP_Query($pinned_args);
while ($pinned_posts->have_posts()){
$pinned_posts->the_post();
//Send this post ID to array so we don't duplicate this in our list
array_push( $pinned_post_arr, get_the_ID());
$Posts = new Posts;
//add each post to the query response data
if($paged == 1){
// DO STUFF WITH YOUR PINNED POSTS HERE.
// Generate HTML or cards, whatever you need
// My use case was to generate HTML and pass it back via AJAX
// this is relative to my project, so copying won't work
query_response['data'] .= $Posts->render_posts();
}
}
wp_reset_postdata(); // ensure you include this line
第 2 步 - 为第二个查询设置变量
（并计算第 2 页及以上的偏移量）
什么是偏移量？
get_posts() & wp_query 的参数
offset (int) – 要替换或越过的帖子数。警告：
设置偏移参数覆盖/忽略分页参数和
打破分页。 'offset' 参数在以下情况下被忽略
'posts_per_page'=>-1（显示所有帖子）被使用。
注意 Wordpress 就分页和分页问题向我们发出的警告。
if($paged == 1){
// if the request from the browser ajax request wants page 1,
// we need the second query to return the right amount of posts.
// This is done by deducting the count of our pinned post array
$post_per_page = 10 - count($pinned_post_arr);
$offset = false; // this is not req but I like to add for sanity
} else {
// If the browser did not request page 1 but requested another page.
// We need to counter the pinned posts using an offset.
// This stops page 2 missing items which page 2 thinks is on page 1.
$post_per_page = 10;
// here, we calculate, based on the page we're on and how many pinned posts there were
// the number 10 is my defined posts per page that I personally wanted.
$offset = ((10-count($pinned_post_arr) ) + (10 * ($paged - 2)));
}
第 3 步 - 第二个查询
$args = array(
'post__not_in' => $pinned_post_arr, // required -exclude already pinned posts
'post_type' => $post_type,
'posts_per_page' => $post_per_page, // required
'post_status' => 'publish',
'orderby' => $orderby,
'order' => $order,
'offset' => $offset, // required
'paged' => $paged, // required
'tax_query' => $tax_query,
);
$wp_query = new \WP_Query($args);
// I used a library called SimplePagination
// https://github.com/flaviusmatis/simplePagination.js
// This required me to send back the number of items.
// I can query found posts as an int but I MUST add the count from pinned posts too
$query_response['numOfItems'] = $wp_query->found_posts + count($pinned_post_arr);
$query_response['postsPerPage'] = 10;
// Get all found posts (not including pinned) and add it to the data query
while ($wp_query->have_posts()) {
$wp_query->the_post();
$Posts = new Posts;
// Here I'm appending more to the AJAX response. Which will follow seamlessly from the pinned posts (if any)
$query_response['data'] .= $Posts->render_posts();
}
wp_reset_postdata(); // reset for safe measures
