💼 Career

Knowing how to register and configure custom post types is essential for WordPress developers building custom websites or plugins.

1

Create the function and basic post type registration

Create a function called register_artwork_post_type and inside it call register_post_type with the post type name 'artwork' and an empty array for arguments.

Wordpress

<?php
// Your code here

Need a hint?

Start by defining the function and call register_post_type with the post type name and empty arguments.

2

Add labels and basic arguments

Inside the register_artwork_post_type function, add an array called $args with a labels key. Set labels to an array with 'name' as 'Artworks' and 'singular_name' as 'Artwork'. Also set public to true and has_archive to true. Pass $args as the second argument to register_post_type.

Wordpress

<?php
function register_artwork_post_type() {
    // Define the arguments array
    // Your code here
    register_post_type('artwork', $args);
}

Need a hint?

Use an array for $args with the required keys and pass it to register_post_type.

3

Enable Gutenberg editor support

Add the show_in_rest argument to the $args array and set it to true to enable the Gutenberg editor for the artwork post type.

Wordpress

 [
            'name' => 'Artworks',
            'singular_name' => 'Artwork'
        ],
        'public' => true,
        'has_archive' => true,
        // Your code here
    ];
    register_post_type('artwork', $args);
}

Need a hint?

Add 'show_in_rest' => true inside the $args array.

4

Hook the function to the init action

Add a line after the register_artwork_post_type function to hook it to the init action using add_action with the function name 'register_artwork_post_type'.

Wordpress

 [
            'name' => 'Artworks',
            'singular_name' => 'Artwork'
        ],
        'public' => true,
        'has_archive' => true,
        'show_in_rest' => true
    ];
    register_post_type('artwork', $args);
}

// Your code here

Need a hint?

Use add_action with 'init' and the function name 'register_artwork_post_type'.
