Heres how to display it using a custom field, this inst my work, but will integrate with my code.
Code:
<?php
add_action('init', 'create_portfolio');
function create_portfolio() {
$portfolio_args = array(
'label' => __('Portfolio'),
'singular_label' => __('Portfolio'),
'public' => true,
'show_ui' => true,
'capability_type' => 'post',
'hierarchical' => false,
'rewrite' => true,
'supports' => array('title', 'editor', 'thumbnail')
);
register_post_type('portfolio',$portfolio_args);
}
?>
