| 55 | * regular expression. This parameter can be passed either to |
| 56 | * {@link HTML_QuickForm2_Rule::__construct() the Rule constructor} as local |
| 57 | * configuration or to {@link HTML_QuickForm2_Factory::registerRule()} |
| 58 | * as global one. As usual, global configuration overrides local one. |
| 59 | * |
| 60 | * The Rule can also validate file uploads, in this case the regular expression |
| 61 | * is applied to upload's 'name' field. |
| 62 | * |
| 63 | * The Rule considers empty fields (file upload fields with UPLOAD_ERR_NO_FILE) |
| 64 | * as valid and doesn't try to test them with the regular expression. |
