# Notes

## Translations

Since 2.0 the `translation()` method has been removed. You can translate any labels and names when you assign them to the PostType or Taxonomy. It was removed to provide more control to the developer while encouraging best practices around internationalizing plugins and themes set out by [WordPress](https://developer.wordpress.org/plugins/internationalization/how-to-internationalize-your-plugin/).

{% hint style="info" %}
The `register()` method hooks into WordPress and sets up the different actions and filters to create your custom post type. For translations to work correctly, wrap your PostTypes code in an `init` action with priority `0`. Avoid wrapping it in other actions/filters as this may lead to unexpected results.
{% endhint %}

```php
add_action( 'init', function() {
    // Translating the post types plural and singular names.
    $books = new PostType( [
        'name'     => 'book',
        'singular' => __( 'Book', 'YOUR_TEXTDOMAIN' ),
        'plural'   => __( 'Books', 'YOUR_TEXTDOMAIN' ),
        'slug'     => 'books',
    ] );

    // Translating labels.
    $books->labels( [
        'add_new_item' => __( 'Add new Book', 'YOUR_TEXTDOMAIN' ),
    ] );
}, 0 );
```

## Custom Fields

The class has no methods for making custom fields for post types, use [Advanced Custom Fields](https://advancedcustomfields.com).

## Examples

The books example used in the README.md can be found in [examples/books.php](https://github.com/jjgrainger/posttypes/blob/master/examples/books.php).
