我有一个按自定义字段排序的自定义帖子的存档页面。我有两个按自定义类别应用过滤器的按钮。结果不符合预期。结果数量正确，但帖子内容不匹配。

这是我的pre\\u get\\u post in函数。php

function xgc_filter_archive( $query ) {
    if ($query->is_main_query()){
        if ( is_admin() ) {
                return;
        }
        if ( is_post_type_archive (\'concerts\') ) {
                if ( \'cat\' === $_GET[\'getby\']  ) {
                            $taxquery = array(
                                    array(
                                            \'taxonomy\' => \'categories_concerts\',
                                            \'field\' => \'slug\',
                                            \'terms\' => $_GET[\'cat\'],
                                    ),
                            );
                            $query->set( \'tax_query\', $taxquery );
                }
        }
        if ( is_post_type_archive (\'obres\') ) {
                if ( \'cat\' === $_GET[\'getby\']  ) {
                        $taxquery = array(
                                array(
                                        \'taxonomy\' => \'categories_obres\',
                                        \'field\' => \'slug\',
                                        \'terms\' => $_GET[\'cat\'],
                                ),
                        )
                        ;
                        $query->set( \'tax_query\', $taxquery );
            }
        }
        return $query;
    }
}
add_action( \'pre_get_posts\', \'xgc_filter_archive\');

这是我的模板：

<section id="menu_categories_obres" class="py-2">
     <div class="filter-custom-taxonomy container justify-content-center">
      <?php
        $terms = get_terms( \'categories_obres\' );
        foreach ( $terms as $term ) : ?>
          <a href="?getby=cat&cat=<?php echo esc_attr( $term->slug ); ?>" class="btn btn-md btn-primary mt-2" tabindex="-1" role="button" aria-disabled="true"><?php echo esc_html( $term->name ); ?>
          </a>
      <?php endforeach; ?>
    </div>
</section>
<section id="llistat_obres" class="py-3">
  <div class="container" style="display: flex;flex-wrap: wrap;">
  <?php 
                // Variables
                // query
                $posts = get_posts(array(
                        \'post_type\'         => \'obres\',
                        \'posts_per_page\'    => -1,
                        \'meta_key\'          => \'any\',
                        \'orderby\'           => \'meta_value\',
                        \'order\'             => \'DESC\'
                         ));
                if( $posts ): 
                    while ( have_posts() ) : the_post();

如果我对主查询进行注释，效果很好，但我并没有按需要进行排序。

感谢您的回复

EDIT:

现在，如果我把这个代码放在函数上。php

function xgc_filter_archive( $query ) {
    if ($query->is_main_query()){
        if ( is_admin() ) {
                return;
        }
        if ( is_post_type_archive (\'concerts\') ) {
                if ( \'cat\' === $_GET[\'getby\']  ) {
                            $taxquery = array(
                                    array(
                                            \'taxonomy\' => \'categories_concerts\',
                                            \'field\' => \'slug\',
                                            \'terms\' => $_GET[\'cat\'],
                                    ),
                            );
                            $query->set( \'tax_query\', $taxquery );
                            $query->set( \'post_type\', \'concerts\'  );
                            $query->set( \'posts_per_page\', -1 );
                            $query->set( \'meta_key\', \'data_del_concert\');
                            $query->set( \'orderby\', \'meta_value\' );
                            $query->set( \'order\', \'DESC\' );
                }
        }
        if ( is_post_type_archive (\'obres\') ) {
            if ( \'cat\' === $_GET[\'getby\']  ) {
                        $taxquery = array(
                                array(
                                        \'taxonomy\' => \'categories_obres\',
                                        \'field\' => \'slug\',
                                        \'terms\' => $_GET[\'cat\'],
                                ),
                        )
                        ;
                        $query->set( \'tax_query\', $taxquery );
                        $query->set( \'post_type\', \'obres\'  );
                        $query->set( \'posts_per_page\', -1 );
                        $query->set( \'meta_key\', \'any\');
                        $query->set( \'orderby\', \'meta_value\' );
                        $query->set( \'order\', \'DESC\' );
            }
        }
            return $query;
    }
}
add_action( \'pre_get_posts\', \'xgc_filter_archive\');

如果我点击过滤器按钮，效果很好，而且顺序也很好，但一开始所有帖子的顺序都是错误的。此代码运行不正常。有什么建议吗？

$posts_list = get_posts(array(
                    \'post_type\'         => \'obres\',
                    \'posts_per_page\'    => -1,
                    \'meta_key\'          => \'any\',
                    \'orderby\'  => \'meta_value\',
                    \'order\'             => \'DESC\',
                     ));
            if( $posts_list ): 
                while ( have_posts() ) : the_post();

谢谢

$posts_list = get_posts(array(
        \'post_type\'         => \'obres\',
        \'posts_per_page\'    => -1,
        \'meta_key\'          => \'any\',
        \'orderby\'           => \'meta_value_num\',
        \'order\'             => \'DESC\',));
if( $posts_list ): 
    while ( have_posts() ) : the_post();
