Question

我正在尝试从名为菜单项的自定义帖子类型输出，但由于某种原因它无法正常工作，有人可以解释我将如何更改以下查询以允许类别correclty我只是得到空结果

  <?php
/*
 * Loop through Categories and Display Posts within
 */
$post_type = 'menu_items';

// Get all the taxonomies for this post type
$taxonomies = get_object_taxonomies( array( 'post_type' => $post_type ) );

foreach( $taxonomies as $taxonomy ) :

    // Gets every "category" (term) in this taxonomy to get the respective posts
    $terms = get_terms( $taxonomy );

    foreach( $terms as $term ) : ?>



        <?php
        $args = array(
                'post_type' => $post_type,
                'posts_per_page' => -1,  //show all posts
                'tax_query' => array(
                 array(
        'taxonomy' => 'category',
        'field' => 'slug',
        'terms' => array ( 'salads-raw-things' ),
    ),
                    array(
                        'taxonomy' => $taxonomy,
                        'field' => 'slug',
                        'terms' => $term->slug,
                    )
                )

            );
        $posts = new WP_Query($args);

        if( $posts->have_posts() ): while( $posts->have_posts() ) : $posts->the_post(); ?>


                    <ul class="menu-list">
                        <li class="menu-item"><?php echo get_the_title(); ?></p>
                            <p class="number">
                             <?php the_field('dish_number',$posts->ID); ?>

                 </li>





        <?php endwhile; endif; ?>


    <?php endforeach;

endforeach; ?>

您只需要循环以创建tax_query参数。每次循环运行时都会覆盖您的查询。

你必须这样做：

foreach( $taxonomies as $taxonomy ) :

// Gets every "category" (term) in this taxonomy to get the respective posts
$terms = get_terms( $taxonomy );

foreach( $terms as $term ) : ?>
    <?php
            tax_query[]  = array(
                    'taxonomy' => $taxonomy,
                    'field' => 'slug',
                    'terms' =>$term                           
           );
endforeach ;
endforeach ;

然后，您只需为一个$args

创建WP_Query

   $args = array(
            'post_type' => $post_type,
            'posts_per_page' => -1,  //show all posts
            'tax_query' => array(
             array(
    'taxonomy' => 'category',
    'field' => 'slug',
    'terms' => array ( 'salads-raw-things' ),
),
     $tax_query
     )
   );

   $query = new WP_Query($args);

不要忘记在每个分类法之间正确设置所需的关系。

希望它能给你一些提示让它有效！

需要更改循环以考虑帖子类别
