Custom Post Type In WordPress Using Code

Register new Custom Post Type manually in WordPress.

In order to register a custom post type in WordPress, we must hook to the init action. The function.php file for the theme must contain the following code:

function prefix_create_custom_post_type() {
$args = array();

register_post_type( 'post-type-slug' , $args );
}
add_action( 'init', 'create_custom_post_type' );

The register_post_type() function, is a part of the prefix_create_custom_post_type() function. It is used to create a custom post type with parameters declared with $args.

Add parameters.

There are many different arguments that can be passed to $args, which makes things quite difficult. Therefore, be careful to be aware of what you require in order to select appropriate arguments. Only use some basic parameters and arguments to create a  custom post type.  

• The $labels are an insignificant parameter. But, it will help identify the post type in the admin section.
• The post type’s support for a title, editor, excerpt, featured picture, and other features is indicated by the $supports argument.

   function prefix_create_custom_post_type() {
    /*
     * The $labels describes how the post type appears.
     */
    $labels = array(
        'name'          => 'Products', // Plural name
        'singular_name' => 'Product'   // Singular name
    );
    /*
     * The $supports parameter describes what the post type supports
     */
    $supports = array(
        'title',        // Post title
        'editor',       // Post content
        'excerpt',      // Allows short description
        'author',       // Allows showing and choosing author
        'thumbnail',    // Allows feature images
        'comments',     // Enables comments
        'trackbacks',   // Supports trackbacks
        'revisions',    // Shows autosaved version of the posts
        'custom-fields' // Supports by custom fields
    ); 
  
     /*
     * The $args parameter holds important parameters for the custom post type
     */

    $args = array(
        'labels'              => $labels,
        'description'         => 'Post type post product', // Description
        'supports'            => $supports,
        'taxonomies'          => array( 'category', 'post_tag' ), // Allowed taxonomies
        'hierarchical'        => false, // Allows hierarchical categorization, if set to false, the 
Custom Post Type will behave like Post, else it will behave like Page
        'public'              => true,  // Makes the post type public
        'show_ui'             => true,  // Displays an interface for this post type
        'show_in_menu'        => true,  // Displays in the Admin Menu (the left panel)
        'show_in_nav_menus'   => true,  // Displays in Appearance -> Menus
        'show_in_admin_bar'   => true,  // Displays in the black admin bar
        'menu_position'       => 5,     // The position number in the left menu
        'menu_icon'           => true,  // The URL for the icon used for this post type
        'can_export'          => true,  // Allows content export using Tools -> Export
        'has_archive'         => true,  // Enables post type archive (by month, date, or year)
        'exclude_from_search' => false, // Excludes posts of this type in the front-end search   result page if set to true, include them if set to false
        'publicly_queryable'  => true,  // Allows queries to be performed on the front-end part if set to true
        'capability_type'     => 'post' // Allows read, edit, delete like “Post”
    );
    register_post_type('product', $args); //Create a post type with the slug is ‘product’ and arguments in $args.
}
add_action('init', 'prefix_create_custom_post_type');

Save the file. Then go back to the admin dashboard.

The following options will appear when your cursor is over this Product tab: All Products to display all posts of that Product type, Add New to create a fresh post in the Product category, etc.

Now just finished the Custom post type using code.
