Field attach API, allowing entities (nodes, users, ...) to be 'fieldable'.

Code

function field_attach_validate($entity_type, $entity) {
  $errors = array();
  // Check generic, field-type-agnostic errors first.

  // Check field-type specific errors.
  _field_invoke('validate', $entity_type, $entity, $errors);

  // Let other modules validate the entity.
  // Avoid module_invoke_all() to let $errors be taken by reference.

    $function = $module . '_field_attach_validate';
    $function($entity_type, $entity, $errors);
