Problem:
In the backend post edit screens repeatable field groups can be re-ordered with drag and drop. How can they be output on the front-end in the same order?

Solution:
The order is stored as a custom field "toolset-post-sortorder", and so the View settings for ordering need to order by that custom field.

Problem: I have a CPT called "Products" and have setup a post relationship with another CPT called "Stockists". On the single-product.php page, I want to output the Stockists that are children of that particular Product. In the output of each Stockist, I want to display an image that is stored as a custom field on the Stockist post. I want to be able to do this in PHP without using Views.

Solution: Use the toolset_get_related_posts API to query for related Stockist posts. Then loop over those results with a foreach statement. In that loop, echo the custom field image using the types_render_field API, and reference the current Stockist post ID in the array of params.

$product_id = get_the_ID();
$relationship_slug = 'product-stockist';
$stockists = toolset_get_related_posts(
  $product_id, // the known item id
  $relationship_slug, // the relationship slug
  'parent', // the known item role in the relationship
  1000000, // a positive integer is required here for the limit
  0, // zero-based index page number
  array(), // no additional params are required here
  'post_id', // whether you want to return an array of post IDs or post objects
  'child' // the role you want to return
);
foreach($stockists as $stockist) {
  echo types_render_field( "stockist-logo", array( "raw"=>"true", "id"=>$stockist ) );
}
