Manage include_children in TOC category

Hi,

I was working with this plugin and noticed that [yadawikitoc show_toc=”true” category=”{category}” order=”date”] doesn’t handle the include_children parameter. Since it’s a very small edit, I made the changes myself and wanted to share them with everyone—maybe someone will find it helpful.

All you need to do is locate the \yada-wiki\inc\functions-public.php file and replace the code from lines 107 to 194 with this:

function yada_wiki_toc_shortcode( $atts ) {
	extract( shortcode_atts( array( 
		'show_toc' => '', 
		'category' => '', 
		'order' => '', 
		'include_children' => false, 
	), $atts ) ); 
	
	$show_toc 	= sanitize_text_field($show_toc);
	$category 	= sanitize_text_field($category);
	$order 		= sanitize_text_field($order);
	$include_children 		= sanitize_text_field($include_children);
	
	return get_yada_wiki_toc( $show_toc, $category, $order, $include_children );
}

//output toc
function get_yada_wiki_toc( $show_toc, $category, $order, $include_children ){
	$show_toc  	= trim($show_toc);
	$category  	= trim($category);
	$order  	= trim($order);
	$order_direction = "ASC";
	
	if($category != "") {
		// Output page title to all in the category
		if($order == "") {
			$order = "title";
		} else if ($order == "datedesc") {
			$order = "date";
			$order_direction = "DESC";
		}
		$args = array( 
			'posts_per_page' 	=> -1, 
			'offset'			=> 0,
			'post_type' 		=> 'yada_wiki',
			'tax_query'			=> array(
									array(
										'taxonomy' => 'wiki_cats', 
										'field' => 'name', 
										'terms' => $category, 
										'include_children' => $include_children
									),
								   ),
			'orderby' 			=> $order,
			'order' 			=> $order_direction,
			'post_status' 		=> 'publish'
		); 	
		$cat_list = get_posts( $args );
		$cat_output = '<ul class="wiki-cat-list">';
		foreach ( $cat_list as $item ) {
			$cat_output = $cat_output . '<li class="wiki-cat-item"><a class="wiki-cat-link" href="' . esc_url(get_post_permalink($item->ID)) . '">'.$item->post_title.'</a></li>';
		}
		$cat_output = $cat_output . '</ul>';
		return $cat_output;
	}
	else if($show_toc == true) {
		
		$the_toc = get_posts(
		    array(
		        'post_type'              => 'yada_wiki',
		        'title'                  => 'TOC',
		        'post_status'            => 'all',
		        'numberposts'            => 1,
		        'update_post_term_cache' => false,
		        'update_post_meta_cache' => false,           
		        'orderby'                => 'post_date ID',
		        'order'                  => 'ASC',
		    )
		);
		if($the_toc) { $the_toc=$the_toc[0]; } 
		
		if (! isset($the_toc) ) {
		    return __('A wiki article with the title of TOC was not found.', 'yada_wiki_domain');
		} 
		else {
			$toc_status = get_post_status( $the_toc );
			
			if( $toc_status == "publish" ) {
				$has_content = $the_toc->post_content;
				if ($has_content) {
					$the_content = apply_filters( 'the_content', $the_toc->post_content );
					return $the_content;				
				} else {
					return __('The TOC has no content.', 'yada_wiki_domain');
				}				
			} else {
				return __('The TOC has not been published.', 'yada_wiki_domain');
			}	
		}
	}
}

Now, you can add “include_children=true” to your shortcode like this: [yadawikitoc show_toc=”true” category=”{category}” order=”date” include_children=true].

Thank you!
