wordpress仅在子类别上显示帖子

Question

hi I'm using Wordpress on developing a site and a self made template. I got 1 page to display all categories with its post. this is what i want to do

• Main Category
  • subcategory1
    • post 1
    • subcategory1.2
      • post 1.2.1
      • post 1.2.2
  • subcategory2
  • subcategory3

i use wp_link_category() to display the category and i search how to display category with post but the problem is. the post from subcategory 1.2 is also display on subcategory 1

• Main Category
  • subcategory1
    • post 1
    • post 1.2.1
    • post 1.2.2
    • subcategory1.2
      • post 1.2.1
      • post 1.2.2
  • subcategory2
  • subcategory3

how can i remove the post from subcategory 1.2 on subcategory 1? here's the code i copy and paste from stackoverflow

$categories =  get_categories('child_of=4');  
foreach  ($categories as $category) {
    //Display the sub category information using $category values like $category->cat_name
    echo '<h2>'.$category->name.'</h2>';
    echo '<ul>';

    foreach (get_posts('cat='.$category->term_id) as $post) {
        setup_postdata( $post );
        echo '<li><a href="'.get_permalink($post->ID).'">'.get_the_title().'</a></li>';   
    }  
    echo '</ul>';
}

i hope you understand my bad english.

Answer 1

try this instead:

$args = array(
  'child_of' => 4,
  'parent' => 4
  );

$categories =  get_categories( $args );
