Custom Post hierarchical to custom taxonomy

Question

I have created a custom post type and a custom taxonomy. The issue is that I can not make the custom posts hierarchical with the categories it is in. I have the following code,

function AppManager_custom_post() {
  $labels = array(
    'name'               => _x( 'APKS', 'post type general name' ),
    'singular_name'      => _x( 'APK', 'post type singular name' ),
    'add_new'            => _x( 'Add New APK', 'APK' ),
    'add_new_item'       => __( 'Add New APK' ),
    'edit_item'          => __( 'Edit APK' ),
    'new_item'           => __( 'New APK' ),
    'all_items'          => __( 'All APKs' ),
    'view_item'          => __( 'View APK' ),
    'search_items'       => __( 'Search APKs' ),
    'not_found'          => __( 'No APK found' ),
    'not_found_in_trash' => __( 'No APKs found in the Trash' ),
  );
  $args = array(
    'labels'        => $labels,
    'description'   => 'Holds Apps and meta data',
    'public'        => true,
    'menu_position' => 5,
    'supports'      => array( 'title', 'thumbnail', 'excerpt' ),
    'has_archive'   => true,
      'hierarchical'  => true,
    'rewrite'       => array('slug' => 'APKs')
  );
  register_post_type( 'apps_post', $args );
  flush_rewrite_rules();
}
add_action( 'init', 'AppManager_custom_post' );

And I have the following to create the taxonomy,

function AppManager_custom_taxonomy() {
  $labels = array(
    'name'              => _x( 'App Categories', 'taxonomy general name' ),
    'singular_name'     => _x( 'App Category', 'taxonomy singular name' ),
    'search_items'      => __( 'Search App Categories' ),
    'all_items'         => __( 'All App Categories' ),
    'parent_item'       => __( 'Parent App Category' ),
    'parent_item_colon' => __( 'Parent App Category:' ),
    'edit_item'         => __( 'Edit App Category' ),
    'update_item'       => __( 'Update App Category' ),
    'add_new_item'      => __( 'Add New App Category' ),
    'new_item_name'     => __( 'New App Category' ),
    'menu_name'         => __( 'App Categories' ),
  );
  $args = array(
    'labels'       => $labels,
    'hierarchical' => true,
    'rewrite'      => array( 'hierarchical' => true, 'slug' => 'Apps' )
  );
  register_taxonomy( 'appCategory', 'apps_post', $args );

}
add_action( 'init', 'AppManager_custom_taxonomy', 0 );

No matter how I try the hierarchical function it never maps to the category that I add it to. Is it possible?

Answer 1

This might not answer your question, but you have a few issues with your code

• Do not use uppercase letters in function names, taxonomy names and custom post type names. Only use lowercase letters. Separate names with a underscore (_). Also, just a tip, never start these names with letters, or use a hyphen (-) to separate names

• Never use flush_rewrite_rules(); in the fashion you have done. It is an extremely expensive operation to use. As it stands, it will load on every page load. This will increase your loading time considerable, which is bad when it comes to SEO. Check the codex for proper use.

• Do not create multiple functions which is hooked to the same hook. Create one function, and hook that function to the desired hook

Make the following modifications, I hope it will do the job

function AppManager_custom_taxonomy() {
  $labels = array(
    'name'              => _x( 'App Categories', 'taxonomy general name' ),
    'singular_name'     => _x( 'App Category', 'taxonomy singular name' ),
    'search_items'      => __( 'Search App Categories' ),
    'all_items'         => __( 'All App Categories' ),
    'parent_item'       => __( 'Parent App Category' ),
    'parent_item_colon' => __( 'Parent App Category:' ),
    'edit_item'         => __( 'Edit App Category' ),
    'update_item'       => __( 'Update App Category' ),
    'add_new_item'      => __( 'Add New App Category' ),
    'new_item_name'     => __( 'New App Category' ),
    'menu_name'         => __( 'App Categories' ),
  );
  $args = array(
    'label'        => $labels,
    'rewrite'      => array( 'slug' => 'Apps' ),
    'hierarchical' => true
  );
  register_taxonomy( 'appCategory', 'apps_post', $args );

}
add_action( 'init', 'AppManager_custom_taxonomy', 0 );
