Wordpress displaying custom post types and their fields - custom-fields

Question

I have set up a Custom Post Type called 'RELEASES' - think music cd release.
This post type has fields named 'release_artist', 'release_title', 'release_date', 'release_artwork' and 'release_tracklisting' for entering all of the relevant music cd information.
I am having real trouble actually displaying this information in my Wordpress template.
I have really only had luck outputting a list of the titles and none of the other data.
Any idea what I put in the LOOP to display all of the information? Preferably each in its own LIST item so I can style each separately?
Any thoughts greatly appreciated.

Answer 1

You can use get_post_meta to pull in your fields as needed. Inside your loop, you can start with the following:
<?php
$release_artist = get_post_meta($post->ID, 'release_artist', true);
$release_title = get_post_meta($post->ID, 'release_title', true);
?>
<ul>
<li class="release_artist">
<?php echo $release_artist; ?>
</li>
<li class="release_title">
<?php echo $release_title; ?>
</li>
</ul>

Answer 2

Are those custom fields? If yes, try what codex.wordpress.org is saying. Better yet, try ACF plugin.

If you want to display parts of your pages on other ones (eg. on your home), you need to use query_posts. This is fairly simple function. For your loop, try something like this:
<?php
global $wp_query;
query_posts(array(
'post_type' => 'releases'
));
while(have_posts()) : the_post(); ?>
<?php $key = get_post_meta($post->ID, 'Opis nazwy'); ?>
<li <?php post_class(); ?>><?php if($key) { echo $key[0]; } else { the_title(); }; ?></li>
<?php
endwhile;
wp_reset_query();
?>
$key is a single value, here set to release_artists. It's purely for testing. If it works - feel free to define your own variables.

You should use:
<?php the_field('field_name') ?>
inside your loop. Hope it helps!

Answer 4

From most of the documentation I've seen online, query_posts shouldn't be the go-to function for creating custom queries and loops. The following code snippet might be a good starting point. You should be able to use this inside or outside of the main loop of your themes template files.
$args = array(
'post_type' => 'release', //remember this is-case sensitive
'posts_per_page' => -1,
);
$releaseQuery = new WP_Query( $args );
if ( $releaseQuery->have_posts() ) :
while ( $releaseQuery->have_posts() ) :
$releaseQuery->the_post();
// Fetching the post ID for demonstration and for use later
$c_id = get_the_ID();
// After running the_post(), alot of the Wordpress functions (not all) can now be used without supplying the post ID.
echo get_the_title();
// You could also have used get_the_title($c_id);
// Then:
echo get_post_meta($c_id, 'release_title', true);
echo get_post_meta($c_id, 'release_artist', true);
endwhile;
endif;
// Return to the current page's main query
wp_reset_query();
// This should now display the page's title
the_title();

About your ID's question:
Every item, like posts and pages in WordPress have an "ID", but they are not normally shown in the lists of them. There are a number of plugins that will add an "ID" column in your admin. Search Wordpress.org for "show ids" and pick one you like. Install it. Activate it. You'll see the ids.
