Hi Friends , Custom post types is one of the main feature of wordpress 3.0. By custom post types you can create any section like post and pages, means you can creat any section exists in your site. Just for example if you have section in your site News then you can create News section by putting a simple code in theme function file and it will create News Section in admin. So in this example I am showing you how we can create custom post types Products in your wordpress.

So below is code to create custom post type products:

add_action('init', 'movies_register');
function movies_register() {
$args = array(
'label' => 'Products',
'public' => true,
'show_ui' => true,
'capability_type' => 'post',
'hierarchical' => false,
'rewrite' => array('slug' => 'products'),
'query_var' => true,
'supports' => array(
'title',
'editor',
'excerpt',
'trackbacks',
'custom-fields',
'comments',
'revisions',
'thumbnail',
'author',
'page-attributes')
) ;
register_post_type('products', $args);
}
