## Code

```php
// Blocks available to authors and contributors.
$wpide_role_blocks = array(
    'core/paragraph', 'core/heading', 'core/list', 'core/list-item', 'core/quote', 'core/image',
    'core/gallery', 'core/embed', 'core/separator', 'core/table', 'core/buttons', 'core/button', 'core/details',
);

add_filter( 'allowed_block_types_all', function ( $allowed, $context ) use ( $wpide_role_blocks ) {
    if ( current_user_can( 'edit_others_posts' ) ) {
        return $allowed;
    }

    if ( empty( $context->post ) ) {
        return $allowed;
    }

    return $wpide_role_blocks;
}, 20, 2 );
```

## Notes

Users who can edit others' posts (editors and administrators) are not limited. Edit the block list to fit your site.
