I am writing my own post type by using register_post_type(). But how can show this plugin when I am adding a new post? The parameters I am using now are:
$labels = array(
'name' => _x('Latest News', 'post type general name'),
'singular_name' => _x('Latest News', 'post type singular name'),
'add_new' => _x('Add New', 'Latest News'),
'add_new_item' => __('Add New Latest News'),
'edit_item' => __('Edit Latest News'),
'new_item' => __('New Latest News'),
'view_item' => __('View Latest News'),
'search_items' => __('Search Latest News'),
'not_found' => __('No Latest News found'),
'not_found_in_trash' => __('No Latest News found in Trash'),
'_builtin' => true,
'parent_item_colon' => ''
);
$args = array(
'labels' => $labels,
'public' => true,
'publicly_queryable' => true,
'exclude_from_search' => false,
'show_ui' => true,
'query_var' => true,
'rewrite' => true,
'capability_type' => 'post',
'hierarchical' => false,
'menu_position' => 20,
'supports' => array('title','editor','author','thumbnail','excerpt','comments','custom-fields'),
'taxonomies' => array('category', 'post_tag')
);
register_post_type('latest-news',$args);
