Querying two taxonomies

我有两种分类法：“指南类型”和“工具”。

它们看起来像这样：

Type of guide

- Article
- Video
- Cheat sheet

Tool

— 学习管理系统

测验工具

- Hide a grades column (article)
- Creating a Gradebook (article)
- Long Answer Question Steps (article)
- Matching Questions (article)
- True or False (article)

- Using the Quiz Tool (video)

- Using the Quiz Tool (cheat sheet)

通知工具

该屏幕截图完美地概括了这个问题：我需要将税务查询限制为只包括标有“测验工具”的项目。

我正在尝试使用tax\\u查询，使用AND关系：

$args = array(
        \'tax_query\' => array(
            \'relation\' => \'AND\', 
            array(
                \'taxonomy\' => \'guide-type\',
                \'field\' => \'slug\',
                \'terms\' => \'video\'
            ),
            array(
                \'taxonomy\' => \'tool\',
                \'field\' => \'slug\',
                \'terms\' => what do I put here to get the current tool (Quiz tool)? 
                )
        )
    );
    $query = new WP_Query( $args );

但我就是想不出如何限制只列出标有“测验工具”的项目。注意“我在这里放什么”部分。

感谢您的帮助。

更新时间：

我突然想到，我不必同时查询这两种分类法，而是退出tax\\u查询并使用“get\\u the\\u category（）”作为$参数的一部分：

// The Query
    $args = array(
        \'tax_query\' => array(
            array(
                \'taxonomy\' => \'guide-type\',
                \'field\' => \'slug\',
                \'terms\' => \'self-paced \'
            )
        ), 
        \'category_name\' => get_the_category()

像这样的？有什么想法可以限制“category\\u name”为我当前正在查看的名称（测验工具）。

特里

function wpse52578_get_current_term_id(){ if( !is_tax() && !is_tag() && !is_category() ) return false; //If we got this far we are on a taxonomy-term page // (or a tag-term or category-term page) $taxonomy = get_query_var( \'taxonomy\' ); $queried_object = get_queried_object(); $term_id = (int) $queried_object->term_id; return $term_id; }

$tool_term_id = wpse52578_get_current_term_id(); $tax_query = array( \'relation\' => \'AND\', array( \'taxonomy\' => \'guide-type\', \'field\' => \'slug\', \'terms\' => \'video\' )); if( $tool_term_id ){ $tax_query[] = array( \'taxonomy\' => \'tool\', \'field\' => \'id\', \'terms\' => $tool_term_id ) } $args = array(\'tax_query\' => $tax_query); $query = new WP_Query( $args );

$posts = get_content_taxonomy(\'tool\', \'quiz-tool\'); function get_content_taxonomy($tax, $section){ $wp_query = new WP_Query(); $wp_query->query(array(\'posts_per_page\' => -1, \'orderby\' => \'title\', \'order\' => \'ASC\', \'tax_query\' => array(array(\'taxonomy\' => $tax, \'field\' => \'slug\', \'terms\' => $section)))); $posts = $wp_query->posts; if(!empty($posts)){ $return = $posts; } return $return; }

// Get an array of current terms, use the last one returned $terms = get_the_terms( $post->ID, \'tool\' ); if ( $terms && ! is_wp_error( $terms ) ) { $current_tax_terms = array(); foreach ( $terms as $term ) { $current_tax_terms[] = $term->name; } //Use end to give me just the last term $current_term = end($current_tax_terms); }

$args = array( \'tax_query\' => array( array( \'taxonomy\' => \'guide-type\', \'field\' => \'slug\', \'terms\' => \'self-paced\' ), array( \'taxonomy\' => \'tool\', \'field\' => \'slug\', \'terms\' => $current_term ) ), \'author_name\' => \'saltcod\' ); $query = new WP_Query( $args ); $the_query = new WP_Query( $args );
