카테고리의 모든 하위 카테고리 나열

예,'child_of' 속성을 ​​사용하여 get_categories () 를 사용할 수 있습니다. 예를 들어 ID가 17 인 카테고리의 모든 하위 카테고리 :

 $args = array('child_of' => 17);
$categories = get_categories( $args );
foreach($categories as $category) { 
    echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';
    echo '<p> Description:'. $category->description . '</p>';
    echo '<p> Post Count: '. $category->count . '</p>';  
}
 

이렇게하면 자손 인 모든 카테고리 (예 : 자녀 및 손자)가 표시됩니다.

직계 하위 카테고리 만 표시하려는 경우 (예 : 하위 항목 만) 'parent' 속성을 ​​사용할 수 있습니다.

 $args = array('parent' => 17);
$categories = get_categories( $args );
foreach($categories as $category) { 
    echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';
    echo '<p> Description:'. $category->description . '</p>';
    echo '<p> Post Count: '. $category->count . '</p>';  
}
 

Yes, you can use get_categories() using 'child_of' attribute. For example all sub categories of category with the ID of 17:

$args = array('child_of' => 17);
$categories = get_categories( $args );
foreach($categories as $category) { 
    echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';
    echo '<p> Description:'. $category->description . '</p>';
    echo '<p> Post Count: '. $category->count . '</p>';  
}

This will get all categories that are descendants (i.e. children & grandchildren).

If you want to display only categories that are direct descendants (i.e. children only) you can use 'parent' attribute.

$args = array('parent' => 17);
$categories = get_categories( $args );
foreach($categories as $category) { 
    echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';
    echo '<p> Description:'. $category->description . '</p>';
    echo '<p> Post Count: '. $category->count . '</p>';  
}
