我刚刚从4.2升级到4.4，现在我的分类查询返回空。在升级之前，它一直运行良好。

我已经注册了一个名为\'title\', 由我的自定义帖子类型使用\'sg-publications\'. 根据WP模板层次结构，我创建了一个名为taxonomy-title.php 它使用默认的查询参数，并且到目前为止已按标题正确显示了每个出版物。

以下是该模板中$queryed\\u object和$wp\\u query->request的输出：

[queried_object] => WP_Term Object
    (
        [term_id] => 1256
        [name] => Stroupe Scoop
        [slug] => stroupe-scoop
        [term_group] => 0
        [term_taxonomy_id] => 1374
        [taxonomy] => title
        [description] => 
        [parent] => 0
        [count] => 30
        [filter] => raw
    )

[queried_object_id] => 1256

[request] => 
SELECT wp_posts.* 
FROM wp_posts 
INNER JOIN wp_term_relationships 
ON (wp_posts.ID = wp_term_relationships.object_id) 
WHERE 1=1 
AND wp_posts.post_title = \'stroupe-scoop\' 
AND ( 
    wp_term_relationships.term_taxonomy_id 
    IN (1374)
    ) 
AND wp_posts.post_type = \'sg-publications\' 
AND (wp_posts.post_status = \'publish\' 
    OR wp_posts.post_status = \'private\'
    ) 
GROUP BY wp_posts.ID 
ORDER BY wp_posts.post_date 
DESC 

我在上面的查询中看到的问题是WHERE 1=1, 出于某种原因，它正在搜索post_title = \'stroupe-scoop\'. 这是不正确的-这是分类术语slug，而不是文章的标题。事实上，当我注释掉这一行并对数据库运行它时，我得到了正确的返回。那么，是什么原因导致WP添加了那个条件，而（我假设）在我升级到4.4之前它并没有添加那个条件呢？

这是分类标题。php：

<?php
/**
 * @package WordPress
 * @subpackage Chocolate
 */
  global $wp_query;

  $quer_object = get_queried_object();
  $tax_desc    = $quer_object->description;
  $tax_name    = $quer_object->name;
  $tax_slug    = $quer_object->slug;

get_header();
get_sidebar();

$title = get_the_title( $ID );
$args  = array(
    \'menu\'            => \'new-publications\',
    \'container\'       => \'div\',
    \'container_id\'    => $tax_slug . \'-menu\',
    \'menu_class\'      => \'menu-top-style nav nav-tab\',
    \'menu_id\'         => \'\',
    \'echo\'            => true,
    \'fallback_cb\'     => false,
    \'before\'          => \'\',
    \'after\'           => \'\',
    \'link_before\'     => \'<i class="fa fa-chevron-circle-right fa-fw fa-2x"></i>\',
    \'link_after\'      => \'\',
    \'items_wrap\'      => \'<ul id="%1$s" class="%2$s">%3$s</ul>\',
    \'depth\'           => 0,
    \'walker\'          => \'\'
);

?>

<div id="page-title">
  <h1><?php _e( \'Publications - \' . $tax_name, LANGUAGE_ZONE ); ?></h1>
  <p><?php _e( \'View our monthly newsletter and stay informed on the latest real estate news.\', LANGUAGE_ZONE ); ?></p>

<?php wp_nav_menu($args); ?>

</div>

<div id="multicol">

<?php
if ( have_posts() ) : while ( have_posts() ) : the_post();

get_template_part( \'loop\' , \'title\' );

endwhile;
endif;
?>

</div><!-- end #multicol -->
<section class="page-text well"><?php _e( $tax_desc, LANGUAGE_ZONE ); ?></section>

<?php
get_footer();

和在函数中。php我有这个查询过滤器：

// use pre_get_posts to remove pagination from publications
function gd_publications_pagination( $query ) {
  if ( is_admin() || ! $query->is_main_query() )
    return;

  if ( is_tax(\'title\') ) {
    // Display all posts for the taxonomy called \'title\'
    $query->set( \'posts_per_page\', -1 );
    return;
  }
}
add_action( \'pre_get_posts\', \'gd_publications_pagination\', 1 );

    if ( \'\' !== $q[\'title\'] ) {
        $where .= $wpdb->prepare( 
            " AND $wpdb->posts.post_title = %s", 
            stripslashes( $q[\'title\'] ) 
        );
    }
