Add Tags to custom post type

Question

I'm using the cherry framework on a WP site. It comes with a custom post type that can be used to add 'Team Members' and create staff pages etc.

I need to expand this so that I can add tags to each 'team member' inorder that I can essentially tag them as working in a department a / b / c / etc.

The custom post type is registered in the theme-init.php file using this code;

/* Our Team */
function my_post_type_team() {
register_post_type( 'team',
    array(
        'label'               => theme_locals("our_team"),
        'singular_label'      => theme_locals("our_team"),
        '_builtin'            => false,
        // 'exclude_from_search' => true, // Exclude from Search Results
        'capability_type'     => 'page',
        'public'              => true,
        'show_ui'             => true,
        'show_in_nav_menus'   => false,
        'menu_position'       => 5,
        'menu_icon'           => ( version_compare( $GLOBALS['wp_version'], '3.8', '>=' ) ) ? 'dashicons-businessman' : '',
        'rewrite'             => array(
                                    'slug'       => 'team-view',
                                    'with_front' => FALSE,
                                ),
        'supports' => array(
                        'title',
                        'editor',
                    'thumbnail',
                    )
    )
);
}
add_action('init', 'my_post_type_team');

I want to add tags to this, so that when I add a new team member, I can also assign them to a department by means of adding a given relevant tag. At present the tag editor box doesn't appear on the add new / edit page.

So, I adapted the above code to include a register taxonomy like this;

/* Our Team */
function my_post_type_team() {
register_post_type( 'team',
    array(
        'label'               => theme_locals("our_team"),
        'singular_label'      => theme_locals("our_team"),
        '_builtin'            => false,
        // 'exclude_from_search' => true, // Exclude from Search Results
        'capability_type'     => 'page',
        'public'              => true,
        'show_ui'             => true,
        'show_in_nav_menus'   => false,
        'menu_position'       => 5,
        'menu_icon'           => ( version_compare( $GLOBALS['wp_version'], '3.8', '>=' ) ) ? 'dashicons-businessman' : '',
        'rewrite'             => array(
                                    'slug'       => 'team-view',
                                    'with_front' => FALSE,
                                ),
        'supports' => array(
                        'title',
                        'editor',
                    'thumbnail',
                    )
    )
);
register_taxonomy(
    'team_tag',
    'team',
    array(
        'hierarchical'  => false,
        'label'         => theme_locals("tags"),
        'singular_name' => theme_locals("tag"),
        'rewrite'       => true,
        'query_var'     => true
    )
);
}
add_action('init', 'my_post_type_team');

However, I'm still not getting the tag box showing up on the edit page in admin.

Any help with this will be greatly appreciated.

Answer 1

It seems the issue was in part down to their being a theme-init.php in the child theme which was overwritting parts of the theme-init.php in the parent / cherry framework theme.

I resolved the issue by adding the following code into my child theme's theme-init.php;

register_taxonomy('team_tag', 'team', array(
    'hierarchical' => false, 
    'label' => theme_locals("tags"), 
    'singular_name' => theme_locals("tag"), 
    'rewrite' => true, 
    'query_var' => true
    )
);

register_post_type( 'team',
    array(
        'label'               => theme_locals("our_team"),
        'singular_label'      => theme_locals("our_team"),
        '_builtin'            => false,
        // 'exclude_from_search' => true, // Exclude from Search Results
        'capability_type'     => 'page',
        'public'              => true,
        'show_ui'             => true,
        'show_in_nav_menus'   => false,
        'menu_position'       => 5,
        'menu_icon'           => ( version_compare( $GLOBALS['wp_version'], '3.8', '>=' ) ) ? 'dashicons-businessman' : '',
        'rewrite'             => array(
                                    'slug'       => 'team-view',
                                    'with_front' => FALSE,
                                ),
        'supports' => array(
                        'title',
                        'editor',
                    'thumbnail',
                    ),
        'taxonomies' => array('team_tag')
    )
);

You can see that I added the taxonomies parameter to the register_post_type function.

Although this code should work, you could try creating the relation later, with this:

add_action('init', 'add_tax_post_rel');

function add_tax_post_rel() {
    register_taxonomy_for_object_type('team_tag', 'team', 11);
}

try this

register_taxonomy(
        'team_tag', 
        'team', 
        array( 
            'hierarchical'  => false, 
            'label'         => __( 'Tags', CURRENT_THEME ), 
            'singular_name' => __( 'Tag', CURRENT_THEME ), 
            'rewrite'       => true, 
            'query_var'     => true 
        )  
    );

Answer 4

You can try this

add_action( 'init', 'create_client_tax' );
function create_client_tax() {
    register_taxonomy( 
            'client_tag', //your tags taxonomy
            'client',  // Your post type
            array( 
                'hierarchical'  => false, 
                'label'         => __( 'Tags', CURRENT_THEME ), 
                'singular_name' => __( 'Tag', CURRENT_THEME ), 
                'rewrite'       => true, 
                'query_var'     => true 
            )  
        );
}

May be this will help you

Answer 5

I was also missing the tags box on admin CPT edit screen. It appeared with adding 'show_in_rest' => true, in the register_taxonomy() params.

Answer 6

If you need to output tags for custom post type - here good example https://jamper.online/vyvod-tegov-tags-dlya-kastomnyh-postov-custom-post-type

    function get_terms_by_custom_post_type( $post_type, $taxonomy ){
    $args = array( 'post_type' => $post_type);
    $loop = new WP_Query( $args );
    $postids = array();
    // build an array of post IDs
    while ( $loop->have_posts() ) : $loop->the_post();
        array_push($postids, get_the_ID());
    endwhile;
    // get taxonomy values based on array of IDs
    $taxonomies = wp_get_object_terms( $postids,  $taxonomy );
    wp_reset_postdata();
    return $taxonomies;
}
