We use the Types plugin to setup different custom products for a client. A certain custom post (product) contains some custom fields which is a drop-down select. When creating a new product of this type, the user may select one option from that list.

For example, let say that certain product has a custom field of type select with the following options set :

1 = Option A
2 = Option B
3 = Option C

Now, in a template, I'm trying to display the label for that custom field. The best thing I came up with is by doing :

$value = reset(get_post_custom_values('custom_field', $post->ID));

which would return a string, for example "1", the value of the custom field. Now, this is worthless as I need to display the label (the chosen item from the list, for example "Option A") in that template.

How do I find the associated label for that custom field value?

Just so you know, and after much code sniffing, I finally have a working solution :

First, the custom field may start with wpcf- (for example: wpcf-custom-field). This prefix may be ignored and only the remaining characters kept. As in

$customField = substr($fieldName, 5);  // $fieldName = 'wpcf-custom-field';

Now, the custom field data may be fetch via the function wpcf_admin_fields_get_field which is located in the Types plugin directory under includes/fields.php. For example :

$fieldConfig = wpcf_admin_fields_get_field($customField);

Among other things, the options may be collected with this code :

$fieldOptions = array();
if (isset($fieldConfig['data']['options'])) {
   foreach ($fieldConfig['data']['options'] as $option) {
      $fieldOptions[$option['title']] = $option['value'];
   }
}

Which, if the custom field is a type select, will return an array like

array(
   '1' => 'Option A',
   '2' => 'Option B',
   '3' => 'Option C'
);
