The Problem:
I made a custom post type and a shortcode to display it’s information. I have done this before and it has not been a problem. When I display this shortcode, the content of the shortcode repeats twice on the page.
The Code:
I added these actions and functions to the bottom of the plugins main file (the one that starts as plugin-name.php in the boilerplate)
function custom_post_type() {
$labels = array(
'name' => _x( 'Carousel ', 'Post Type General Name', 'text_domain' ),
'singular_name' => _x( 'Carousel', 'Post Type Singular Name', 'text_domain' ),
'menu_name' => __( 'Carousel', 'text_domain' ),
'name_admin_bar' => __( 'Carousel', 'text_domain' ),
'archives' => __( 'Carousel Archives', 'text_domain' ),
'parent_item_colon' => __( 'Parent Item:', 'text_domain' ),
'all_items' => __( 'All Posts', 'text_domain' ),
'add_new_item' => __( 'Add New', 'text_domain' ),
'add_new' => __( 'Add New', 'text_domain' ),
'new_item' => __( 'New Carousel', 'text_domain' ),
'edit_item' => __( 'Edit Carousel', 'text_domain' ),
'update_item' => __( 'Update Carousel', 'text_domain' ),
'view_item' => __( 'View Carousel', 'text_domain' ),
'search_items' => __( 'Search Featured Blogs', 'text_domain' ),
'not_found' => __( 'Not found', 'text_domain' ),
'not_found_in_trash' => __( 'Not found in Trash', 'text_domain' ),
'featured_image' => __( 'Featured Image', 'text_domain' ),
'set_featured_image' => __( 'Set featured image', 'text_domain' ),
'remove_featured_image' => __( 'Remove featured image', 'text_domain' ),
'use_featured_image' => __( 'Use as featured image', 'text_domain' ),
'insert_into_item' => __( 'Insert into item', 'text_domain' ),
'uploaded_to_this_item' => __( 'Uploaded to this item', 'text_domain' ),
'items_list' => __( 'Items list', 'text_domain' ),
'items_list_navigation' => __( 'Items list navigation', 'text_domain' ),
'filter_items_list' => __( 'Filter items list', 'text_domain' ),
);
$args = array(
'label' => __( 'Post Type', 'text_domain' ),
'description' => __( 'Post Type Description', 'text_domain' ),
'labels' => $labels,
'supports' => array( ),
'taxonomies' => array( 'category', 'post_tag' ),
'hierarchical' => false,
'public' => true,
'show_ui' => true,
'show_in_menu' => true,
'menu_position' => 5,
'show_in_admin_bar' => true,
'show_in_nav_menus' => true,
'can_export' => true,
'has_archive' => true,
'exclude_from_search' => false,
'publicly_queryable' => true,
'capability_type' => 'page',
'menu_icon' => 'dashicons-welcome-view-site',
);
register_post_type( 'zeebo-carousel', $args );
}
add_action( 'init', 'custom_post_type', 0 );
function carousel_shortcode_func( $atts ) {
$a = shortcode_atts( array(
'id' => false,
'foo' => 'something',
'bar' => 'something else',
), $atts );
ob_start();
?>
shortcode content here<br />
<?php
return ob_get_contents();
}
add_shortcode( 'carousel', 'carousel_shortcode_func' );
Actions I have Already Taken to Fix This:
1. Changed themes
2. Deactivated all other plugins
3. Rewrote the code
3. Google Search
How do I make the content only show once per shortcode?

This is more about php than wp, but ob_get_contents returns the buffer without clearing it. So you get your buffer content twice. Use ob_get_clean to erase the buffer on returning it.
