A little new to the plugin development world, but so far I am building a post type plugin to support hierarchical categories in a list form with multiple depth levels (the structure I want is similar to: http://msdn.microsoft.com/en-us/library/windows/apps/br211362.aspx). The issue is although I can retrieve all post categories under the top parent category, it doesn’t show depth levels if there are multiple sub category levels. I want to allow as much depth as needed and create a list to show for it. For example, right now in the WP Admin I have the category structure:
Parent
- Child Category
-- Sub category of the child category
--- another level of category
- 2nd Child Category
But when I assign the posts to the categories above, the sidebar/widget that displays the posts will only display them underneath the Parent only and not in a hierarchical tree:
Parent
- Posts in Child Category
- Posts in Sub category of the child category
- Posts assigned to another level of category
- Posts in 2nd Child Category
Instead I want it to mimic the depth and hierarchical structure as the categories set up in the backend… Below is the PHP code I am using for the widget… not sure how to modify it.
foreach ( $sorted_termchildren as $child_id => $order ) {
$termobject = get_term_by( 'id', $child_id, 'isa_docs_category' );
//Display the sub Term information, in open widget container
//echo '<aside class="widget well"><h3 class="widget-title">' . $termobject->name . '</h3>';
echo '<ul>';
// nest a loop through each child cat's posts
global $post;
$args = array( 'post_type' => 'isa_docs',
'posts_per_page' => -1,
'order' => 'ASC',
'tax_query' => array(
array(
'taxonomy' => 'isa_docs_category',
'field' => 'id',
'terms' => $termobject->term_id
)
),
'orderby' => 'meta_value_num',
'meta_key' => '_odocs_meta_sortorder_key',
'order' => 'ASC'
);
$postlist = get_posts( $args );
foreach ( $postlist as $single_post ) {
echo '<li';
if( $single_post->ID == $current_single_postID )
echo ' class="organized-docs-active-side-item"';
echo '><a href="' . get_permalink( $single_post->ID ) . '" title="' . esc_attr( $single_post->post_title ) . '">' . $single_post->post_title . '</a></li>';
}
echo '</ul>';
} // end foreach ( $sorted_termchildren
Otherwise, is there simply another plugin that does this already? I’ve searched everywhere. I would like to create this myself, just not sure how to make the code work accordingly. How can I fix this?
