I have installed the Custom Post Type UI plugin. After activation of this plugin I have created a custom post type called portfolio. Now I want to use this on the portfolio page in the front-end. How do I fetch all post that are of custom post type portfolio?

query_posts( array( 'post_type' => array('post', 'portfolio') ) );

which shows both normal posts and posts inside portfolio type

or

query_posts('post_type=portfolio');

for only portfolio.

Use as normal WP Query - read the Codex: http://codex.wordpress.org/Function_Reference/query_posts#Usage and http://codex.wordpress.org/Function_Reference/query_posts#Post_.26_Page_Parameters

<?php 
    query_posts(array( 
        'post_type' => 'portfolio',
        'showposts' => 10 
    ) );  
?>
<?php while (have_posts()) : the_post(); ?>
        <h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2>
        <p><?php echo get_the_excerpt(); ?></p>
<?php endwhile;?>

Late answer as the main answer uses query_posts(), which should never be done.

Use a filter

Use the pre_get_posts filter and just set the portfolio post type for the main query. Use Conditional Tags to determine where you want to have this filter.

Quick Example

<?php
defined( 'ABSPATH' ) OR exit;
/* Plugin Name: (#6417) "Portfolio" post type in query */

add_filter( 'pre_get_posts', 'wpse_6417_portfolio_posts' );
function wpse_6417_portfolio_posts( $query )
{
    if (
        ! $query->is_main_query()
        // Here we can check for all Conditional Tags
        OR ! $query->is_archive() // For e.g.: Every archive will feature both post types
    )
        return $query;

    $query->set( 'post_type', array( 'post', 'portfolio' ) );

    return $query;
}

Disclaimer

The above code is a plugin, but can simply get stuffed in the functions.php file of your theme (which is not recommended).

  • why is it not recommended to add it to functions? Surely, if the site admin changes the theme they would need to address how to display the portfolio on the home page with this new theme anyway. So, I would say it is just as valid to add this in functions rather than a plugin. Or am I missing something? – Phill Healey Nov 29 '16 at 20:21
  • @PhillHealey As you said, the data would be invisible and you would have to copy and paste the code around. Heavy, logic modifications to queries are best served via plugins, while displaying and styling should be kept in themes. – kaiser Nov 29 '16 at 20:45
  • Not if that code is specific to the theme. – Phill Healey Dec 3 '16 at 21:27
  • @PhillHealey A post type should never be specific to a theme. – kaiser Dec 4 '16 at 18:33
  • Ok, if you want to get in some tit-for-tat over absolutes then fine. However, It's just not correct to say that none design specific code should be pushed out to a plugin. There are lots of times when that's not appropriate. – Phill Healey Dec 5 '16 at 18:23

Add this code to your child themes functions file (recommended) to add your single CPT pages to your main loop

add_action( 'pre_get_posts', 'add_custom_post_types_to_loop' );

function add_custom_post_types_to_loop( $query ) {

if ( is_home() && $query->is_main_query() )

$query->set( 'post_type', array( 'post', 'portfolio' ) );

return $query;

}

Source http://codex.wordpress.org/Post_Types

Or create a custom archive-portfolio.php page template which will only display your CPT pages. This only needs to be done if you haven't added a archive page using the plugin settings.

Example: 'has_archive' => true,

You can also control how many pages are displayed and the order in which they're displayed on the archive page using this code:

add_action( 'pre_get_posts', 'cpt_items' );

function cpt_items( $query ) {

if( $query->is_main_query() && !is_admin() && is_post_type_archive( 'portfolio' ) ) {

$query->set( 'posts_per_page', '8' );

$query->set( 'order', 'ASC' );

    }

}
