Usage in templates:

if( function_exists( 'view_quotes_posts' ) ) {
    echo view_quotes_posts();

Show list of all not empty custom taxonomies (custom post type categories):

$tax_name = 'quote_category';
$args = array(
	'hide_empty' => false,
	'hierarchical' => false,
	'parent' => 0
$taxonomies = get_terms($tax_name, $args);
echo '<ul class="taxonomy">';
foreach( $taxonomies as $taxonomy ){
	$link = get_term_link( $taxonomy, $tax_name );
	echo '<li>';
	echo '<a href="'.$link.'">';
	echo $taxonomy->name;
	echo '</a>';
	$sub_args = array(
		'hide_empty' => false,
		'hierarchical' => false,
		'parent' => 0
	$sub_taxonomies = get_terms($tax_name, $sub_args);
	$children = get_term_children( $taxonomy->term_id, $tax_name );
	echo ' c= '.count($children);
	echo '</li>';
echo '</ul>';

List of custom post types (archive) can be viewed by such link: http://site.com/quote/
WordPress by default uses the archive template of your theme to display the custom post type archive page - archive.php.
If you want to create a custom archive page for your custom post type, then you would need to create a new file called archive-quote.php.

Example of archive-quote.php file:

if(have_posts()) : while(have_posts()) : the_post();
	echo '<div class="entry-content">';
	echo '</div>';
endwhile; endif;

    Great code and extremely useful to me! I'm trying to extend it a bit, by having a frontend quote entry form. My first thought was to replicate and then adapt the view_quotes_posts function at the very of the main file, so it can be inserted on template files. How would you do it?

      1. Jeremy

        It is not necessary to close the final PHP tag. In fact, I would recommend not closing it unless you have to.

        That way, a stray linebreak at the end of your source code won't cause the white screen of death.

    I am wondering how I can enable people to read my posts in their native language (Hindi). Is creating custom post type good idea? Will it enable me to post and get comments in the native language?

    Do you know a better alternative?

    At present I am using google translate box and I tell they can send comments to my email using gmail in their language.

    Do you have better ideas to take this forward?

      Custom post types will not help you to force people to read posts in Hindi. Custom post types are needed to create completely new type of posts, like products or services with another structure than in default posts.

      If you want for people to read posts on Hindi than just write your posts on Hindi and when Google will index that posts than Google will send users to your site who will search on Hindi.
      If users will like the articles than they will return to you more frequently.

      So the best advice to promote your native Hindi language for users is to write useful articles for users on that language. Nothing else will not help you with it.

    Where do we place the php code for register_post_type to create the custom post type? Is it its own file? If so, where does this file go? Do we add it to an existing file?

    1. webvitaly

      you should insert this code into functions.php of active theme or you may create a new plugin and insert code there

        1. Saeed

          For that you need to work on child theme
          Just create a theme-child folder and place a style.css and functions.php and write all the relevant code inside it
