How to add an extra menu to wordpress admin screen

Question

I'm trying to create a theme in wordpress and I need to add under where it says 'posts' another page named portfolio, which will act the same as the posts page but use the link of /portfolio/post-title rather than /blog/post-title. There are probably tutorials for this but I can't find any specific to what I'm doing.

Answer 1

Yes, there are tutorials for this thousands, if not millions. I assume you haven't tried very much? The functionality you should look into is "Custom Post Types"

Example:

function codex_custom_init() {
  $labels = array(
    'name' => 'Books',
    'singular_name' => 'Book',
    'add_new' => 'Add New',
    'add_new_item' => 'Add New Book',
    'edit_item' => 'Edit Book',
    'new_item' => 'New Book',
    'all_items' => 'All Books',
    'view_item' => 'View Book',
    'search_items' => 'Search Books',
    'not_found' =>  'No books found',
    'not_found_in_trash' => 'No books found in Trash', 
    'parent_item_colon' => '',
    'menu_name' => 'Books'
  );

  $args = array(
    'labels' => $labels,
    'public' => true,
    'publicly_queryable' => true,
    'show_ui' => true, 
    'show_in_menu' => true, 
    'query_var' => true,
    'rewrite' => array( 'slug' => 'book' ),
    'capability_type' => 'post',
    'has_archive' => true, 
    'hierarchical' => false,
    'menu_position' => null,
    'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' )
  ); 

  register_post_type( 'book', $args );
}
add_action( 'init', 'codex_custom_init' );
