$fields API variable / Fields class

Manages all custom fields in ProcessWire, independently of any Fieldgroup.

Each field returned is an object of type Field. The $fields API variable is iterable:

foreach($fields as $field) {
  echo "<p>Name: $field->name, Type: $field->type, Label: $field->label</p>";
}
