Selecting Post Formats

Hi,

Meta Box has not supported a field to select the post format yet. But we can create a custom field radio with options like WordPress post formats. Sample code below:

$meta_boxes[] = [
  'title'  => __( 'Post Meta', 'your-text-domain' ),
  'id'     => 'post-meta',
  'fields' => [
    [
      'name'    => __( 'Post Format', 'your-text-domain' ),
      'id'      => $prefix . 'post_format',
      'type'    => 'radio',
      'options' => [
        'gallery' => __( 'Gallery', 'your-text-domain' ),
        'aside'   => __( 'Aside', 'your-text-domain' ),
        'status'  => __( 'Status', 'your-text-domain' ),
        'link'    => __( 'Link', 'your-text-domain' ),
        'image'   => __( 'Image', 'your-text-domain' ),
        'quote'   => __( 'Quote', 'your-text-domain' ),
        'video'   => __( 'Video', 'your-text-domain' ),
        'audio'   => __( 'Audio', 'your-text-domain' ),
        'chat'    => __( 'Chat', 'your-text-domain' ),
      ],
      'inline'  => false,
    ],
  ],
];

Use the action hook rwmb_{$field_id}_after_save_field to set post format after saving the custom field.

add_action( 'rwmb_post_format_after_save_field', function( $null = true, $field, $new, $old, $object_id ) {
    set_post_format( $object_id, $new );
}, 10, 5 );

Ok, then we can use the function get_post_format() to get the post format as default feature post format.

Hi Rebecca,

You can add the code to the file functions.php in the theme/child theme folder or use the plugin Code Snippets https://wordpress.org/plugins/code-snippets/.
