Question

所以我对wordpress中的循环有这个问题我的网站有以下结构：

父类别1
- 儿童类别1
- 儿童类别2
家长类别2
- 儿童类别1
- 儿童类别2
- - Post Cat2.1
- - Post Cat2.2
- Post 1
- Post 2

在这种情况下，“父类别2”具有子类别和帖子。我需要在“父类别页面”中显示的是子类别及其没有子类别帖子的帖子我到处都看，但似乎我一直在寻找错误，任何帮助都将非常感激

我认为这有助于：

$cat_id = get_query_var('cat');

if( ! empty( $cat_id ) ) {
$category = get_category( $cat_id, ARRAY_A );

if( ! empty( $category ) ) {
    // parent category
    if( $category['parent'] === '0' ) {

        // get child IDs
        $terms = get_term_children( $cat_id, 'category' );

        foreach( $terms as $term_id ) {
            $child_category = get_term( $term_id, 'category' );

            // if you need the category
            $category_name = $child_category->name;


            /**
             * Sample data in your child category object: 
             * 
             * object(stdClass)[365]
                      public 'term_id' => string '14' (length=2)
                      public 'name' => string 'Child 1' (length=7)
                      public 'slug' => string 'child-1' (length=7)
                      public 'term_group' => string '0' (length=1)
                      public 'term_taxonomy_id' => string '14' (length=2)
                      public 'taxonomy' => string 'category' (length=8)
                      public 'description' => string '' (length=0)
                      public 'parent' => string '12' (length=2)
                      public 'count' => string '5' (length=1)
                      public 'object_id' => string '33' (length=2)
             * 
             * 
             */

            // do whatever you like with the categories now...
        }

    } else { // in child category
        // do the regular loop here, if ( have_posts() ) ...
    }
 }
}
