我只想one 发布和此需要the latest one 下面是我正在做的：
$basic_args = $wp_query->query_vars;
$basic_args[\'tax_query\'] = $wp_query->tax_query;
$aditional_args = array(
\'post__in\' => get_option(\'sticky_posts\'),
\'ignore_sticky_posts\' => 1,
\'order\' => \'desc\',
\'post_status\' => \'publish\',
\'posts_per_page\' => 1
);
$normal_args = array_merge($basic_args, $aditional_args);
$normal_query = new WP_Query($normal_args);
$prev_post_ids = array();
if (!$normal_query->have_posts()) {
$normal_args = array_merge($basic_args, array(\'posts_per_page\' => 1));
$normal_query = new WP_Query($normal_args);
}
echo $normal_query->post_count; // returns 25
if ($normal_query->have_posts()) {
while ($normal_query->have_posts()) {
....
// here I got 25 results instead of just one
}
}
我知道
posts_per_page 应该是限制多少职位，我会得到，但不是为我工作，不知道为什么。正如你所看到的，我在循环中得到了25个帖子，而不是一个。有人能就这个话题给我一些建议吗？我读过
this 和
this 但一点帮助都没有。
Update1
我调试
$normal_query->request 根据建议
@pieter-goosen 我得到了错误的SQL查询：
SELECT SQL_CALC_FOUND_ROWS wp_posts.ID FROM wp_posts INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) INNER JOIN wp_term_relationships AS tt1 ON (wp_posts.ID = tt1.object_id) WHERE 1=1 AND ( wp_term_relationships.term_taxonomy_id IN (6) AND tt1.term_taxonomy_id IN (6) ) AND wp_posts.post_type IN (\'opinion\', \'post\', \'especiales\') AND ((wp_posts.post_status = \'publish\')) GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 25
其中
LIMIT 是否已修改？
Update2
我还调试了
$basic_args 其中有
$wp_query->query_vars 还有
$normal_args 结果如下：
echo \'<pre>\';
print_r($basic_args);
echo \'</pre>\';

如你所见
post_per_page 设置为
1 这就是为什么要花25美元？
Update 3
显然这就是
functions.php:
function change_wp_search_size($query)
{
if ($query->is_search) {
$query->query_vars[\'posts_per_page\'] = 25;
} // Change 25 to the number of posts you would like to show
return $query; // Return our modified query variables
}
add_filter(\'pre_get_posts\', \'change_wp_search_size\');
这不应该只适用于搜索吗？为什么总是对所有query\\u vars进行操作？
