带有TAX_QUERY的PRE_GET_POST导致结果为空

我需要按以下方式调整所有归档页面的主循环。我已经注册了自定义分类法“myposttypes”。每一篇文章都被分配给一个术语“myposttypes”。

如果是类别或标记存档页面，则查询结果中只应包含带有“myposttypes->term1”的帖子。

如果是自定义分类法归档页面，则查询结果中只应包含带有“myposttypes->term2”的帖子。

我已经执行了相应的pre_get_posts 钩住但I\'m not getting any results at all for all my archive pages. 在我的博客实例中，我有很多带有相应分类法的帖子，所以应该会有结果。

以下是我的方法：

function wpmw_adjust_archive_queries( $query ) {
    if ( ! is_admin() && is_archive() && $query->is_main_query() ) {
        if ( is_category() || is_tag() ) $term_slug  = \'term1\';
        if ( is_tax( \'beitragsarten\', \'news\' ) ) $term_slug = \'term2\';

        $taxquery = array(
            \'tax_query\' => array(
                array(
                    \'taxonomy\' => \'myposttypes\',
                    \'field\'    => \'slug\',
                    \'terms\'    => $term_slug
                ),
            ),
        );

        $query->set( \'tax_query\', $taxquery );
    }
}

add_action( \'pre_get_posts\', \'wpmw_adjust_archive_queries\' );

UPDATE:这是我经过调整和简化的方法，不幸的是，这仍然不起作用。我得到一个空结果。I var\\u dump\'ed$query和tax\\u query似乎正确添加到query\\u vars中。

function wpmw_adjust_archive_queries( $query ) {
    if ( ! is_admin() && $query->is_archive() && $query->is_main_query() ) {

        $tax_query = $query->get( \'tax_query\' ) ? : array();

        $tax_query[] = array(
            \'taxonomy\' => \'myposttypes\',
            \'field\'    => \'slug\',
            \'terms\'    => array( \'term1\' ),
            \'operator\' => \'IN\'
        );

        $query->set( \'tax_query\', $tax_query );
    }
}

add_action( \'pre_get_posts\', \'wpmw_adjust_archive_queries\' );

下面是$查询的对应部分

[tax_query] => Array
                (
                    [0] => Array
                        (
                            [taxonomy] => myposttypes
                            [field] => slug
                            [terms] => Array
                                (
                                    [0] => term1
                                )

                            [operator] => IN
                        )

                )

$taxquery = array( \'post_type\' => \'post\', \'tax_query\' => array( array( \'taxonomy\' => \'myposttypes\', \'field\' => \'slug\', \'terms\' => $term_slug ), ), );

$tax_query = $query->get( \'tax_query\' ); if ( ! is_array( $tax_query ) ) { $tax_query = array(); } $taxquery[] = array( \'taxonomy\' => \'myposttypes\', \'field\' => \'slug\', \'terms\' => $term_slug ); $query->set( \'tax_query\', $taxquery );

function wpmw_adjust_archive_queries( $query ) { if ( ! is_admin() && is_archive() && $query->is_main_query() ) { if ( is_category() || is_tag() ) $term_slug = \'term1\'; if ( is_tax( \'beitragsarten\', \'news\' ) ) $term_slug = \'term2\'; $taxquery = array( \'tax_query\' => array( array( \'taxonomy\' => \'myposttypes\', \'field\' => \'slug\', \'terms\' => $term_slug ), ), ); $query->set( \'tax_query\', $taxquery ); } } add_action( \'pre_get_posts\', \'wpmw_adjust_archive_queries\' );

function wpmw_adjust_archive_queries( $query ) { if ( ! is_admin() && $query->is_archive() && $query->is_main_query() ) { $tax_query = $query->get( \'tax_query\' ) ? : array(); $tax_query[] = array( \'taxonomy\' => \'myposttypes\', \'field\' => \'slug\', \'terms\' => array( \'term1\' ), \'operator\' => \'IN\' ); $query->set( \'tax_query\', $tax_query ); } } add_action( \'pre_get_posts\', \'wpmw_adjust_archive_queries\' );

[tax_query] => Array ( [0] => Array ( [taxonomy] => myposttypes [field] => slug [terms] => Array ( [0] => term1 ) [operator] => IN ) )

$taxquery = array( \'post_type\' => \'post\', \'tax_query\' => array( array( \'taxonomy\' => \'myposttypes\', \'field\' => \'slug\', \'terms\' => $term_slug ), ), );
