In order to create and use custom post types on your WordPress website, you need to be sure that your WordPress theme contains the correct code and functions. In the following steps, you create a very basic and generic custom post type called “Generic Content,” and you also find detailed information on the different parameters you can use with custom post types to create different types to suit your needs:
In your Dashboard, choose Appearance→Editor link.
The Edit Themes page opens.
Click the Theme Functions template link to open the functions.php file.
The Theme Functions template opens in the text editor in the middle of the page.
Add the custom post type code to the bottom of the theme functions template file.
Scroll down to the bottom of the functions.php file and include the following code to add a Generic Content custom post type to your site:
// ADD CUSTOM POST TYPE
add_action( 'init', 'create_post_type' );
function create_post_type() {
register_post_type( 'generic-content',
array(
'labels' => array(
'name' => __( 'Generic Content' ),
'singular_name' => __( 'Generic Content' )
),
'public' => true
)
);
}The function register_post_type(); can accept several arguments and parameters, which is detailed in the table. You can use a variety and a combination of arguments and parameters to create a specific post type. You can find more information on custom post types and using the register_post_type(); function on the WordPress Codex page.
Click the Update File button to save the changes made to the functions.php file.
