If you’ve created a login page that isn’t at /wp-login.php, here’s a simple way you can redirect users who click on the “Log In” links to your new page:
add_filter( 'login_url', 'new_login_url', 10, 2 );
function new_login_url( $login_url, $redirect ) {
return '/log-in/';
}
Adding a new post type, for when ‘posts’ and ‘pages’ just won’t do.
add_action( 'init', 'my_new_post_types' );
function my_new_post_types() {
$labels = array(
'name' => _x('Hotels', 'post type general name'),
'singular_name' => _x('Hotel', 'post type singular name'),
'add_new' => _x('Add New', 'hotel'),
'add_new_item' => __('Add New Hotel'),
'edit_item' => __('Edit Hotel'),
'new_item' => __('New Hotel'),
'view_item' => __('View Hotel'),
'search_items' => __('Search Hotels'),
'not_found' => __('No hotels found'),
'not_found_in_trash' => __('No hotels found in Trash'),
'parent_item_colon' => '',
'menu_name' => 'Hotels'
);
$args = array(
'labels' => $labels,
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'query_var' => true,
'rewrite' => true,
'capability_type' => 'post',
'has_archive' => true,
'hierarchical' => false,
'menu_position' => null,
'supports' => array('title','editor','author','thumbnail','excerpt','comments')
);
register_post_type('hotel',$args);
}
When you need more than just ‘categories’ and ‘tags’ use custom taxonomies.
Especially useful in combination with custom post types.
add_action('init', 'my_new_taxonomies');
function my_new_taxonomies() {
$labels = array(
'name' => __( 'Action Hooks' ),
'singular_name' => __( 'Action Hook' ),
'search_items' => __( 'Search Action Hooks' ),
'popular_items' => __( 'Popular Action Hooks' ),
'all_items' => __( 'All Action Hooks' ),
'parent_item' => null,
'parent_item_colon' => null,
'edit_item' => __( 'Edit Action Hook' ),
'update_item' => __( 'Update Action Hook' ),
'add_new_item' => __( 'Add New Action Hook' ),
'new_item_name' => __( 'New Action Hook' ),
'separate_items_with_commas' => __( 'Separate hooks with commas' ),
'add_or_remove_items' => __( 'Add or remove hooks' ),
'choose_from_most_used' => __( 'Choose from the most used hooks' ),
'menu_name' => __( 'Action Hooks' ),
);
register_taxonomy('action_hook','post',array(
'hierarchical' => false,
'labels' => $labels,
'show_ui' => true,
'query_var' => true,
'rewrite' => array( 'slug' => 'action_hook' ),
));
}
