Piklist uses a 12 column grid. So each row of fields should equal 12. Try this:

piklist( 'field', array(
  'type' => 'group',
  'field' => 'home_news',
  'label' => 'Featured News',
  'description' => 'Information for the home page news feature.',
  'template' => 'field',
  'fields' => array(
    array(
      'type' => 'text',
      'field' => 'section_title',
      'columns' => 8, // First row: 8 columns
      'label' => 'News Section Title',
      'value' => "What's New",
    ),
    array(
      'type' => 'number',
      'field' => 'section_quantity',
      'label' => 'Number of Posts',
      'description' => 'How many recent posts should we display?',
      'columns' => 4, // First row: 4 columns. Row will end here because 12 columns have been reached.
      'value' => 2,
      'validate' => array(
        array(
          'type' => 'range',
          'options' => array(
            'min' => 1,
            'max' => 4,
          ),
        ),
      ),
    ),
    array(
      'type' => 'text',
      'field' => 'section_link_text',
      'label' => 'Text for Link to News Page',
      'value' => 'View All News',
      'columns' => 12, // Second row starts here
      'validate' => array(
        array(
          'type' => 'safe_text',
        ),
      ),
    ),
  ),
));

Thanks, Donna. We’ll look into it.

@devonanderson– We’ve been trying to reproduce but can’t. Can you verify that you have the table wp_termmeta in your db? This came up with another user.

@rcantor– The json api has a filter, json_api_encode, that you can use to manipulate the data before the output.

Try this:

add_filter('json_api_encode', 'my_json_api_encode');
function my_json_api_encode($data)
{
  // Are we on a single post
  if (is_single())
  {
    // Get the sources_group field
    $sources_group = get_metadata('post', $data['post']->id, 'sources_group', true);
      
    if ($sources_group)
    {
      foreach ($sources_group as $index => &$group)
      {
        // Add the index to the objecdt
        $group['order'] = $index;
      }
  
      // Add updated object back to the json
      $data['post']->sources_group = $sources_group;
    }
  }

  return $data;
}

It should render like this:

"sources_group":[
	{
		"source_title":"title 1"
		,"source_text":"text 1"
		,"source_url":"http:\/\/piklist.com"
                ,"order":0
	}
	,
	{
		"source_title":"title 2"
		,"source_text":"text 2"
		,"source_url":"http:\/\/google.com"
                ,"order":1
	}
]

Let me know if that works for you.

@kplaneta– Piklist uses the WordPress settings api, which will reject anything that’s not a field. Then Piklist will render that markup on top. You can use the Piklist HTML field to render out what you want.

piklist('field', array(
    'type' => 'html'
    ,'label' => '<h3>My title</h3>
  ));

Thanks. This will be updated in 0.9.9.5.

WordPress stores this data in a serialized array. You can unserialize two ways:
1) Use the standard WordPress function get_post_meta:
$sources_group = get_post_meta($post->ID, 'sources_group', true);

2) Unserialize with the standard PHP function, unserialize.

Does that make sense?
