Defines a field type for referencing products from other entities.

Code

  $options = array();

  // Look for an options list limit in the field settings.
  if (!empty($field['settings']['options_list_limit'])) {

  }
  else {

    // If there is no such limit, then default it to NULL (i.e. no limit) unless
    // a variable has been set that provides an alternate default. This is
    // usually required when product matching has been configured to use an
    // EntityFieldQuery instead of the standard db_select(). Refer to the inline
    // comments in commerce_product_match_products() for more information.
