| 52 | * Rule checking that uploaded file size does not exceed the given limit |

| 54 | * The Rule needs one configuration parameter for its work: the size limit. |
| 55 | * This limit 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()} as |
| 58 | * global one. As usual, global configuration overrides local one. |
| 59 | * |
| 60 | * Note that if file upload failed due to upload_max_filesize php.ini setting |
| 61 | * or MAX_FILE_SIZE form field, then this rule won't even be called, due to |
| 62 | * File element's built-in validation setting the error message. |
| 63 | * |
| 64 | * The Rule considers missing file uploads (UPLOAD_ERR_NO_FILE) valid. |
