|
* The Rule needs one configuration parameter for its work: a Perl-compatible
|
|
* regular expression. This parameter can be passed either to
|
|
* {@link HTML_QuickForm2_Rule::__construct() the Rule constructor} as local
|
|
* configuration or to {@link HTML_QuickForm2_Factory::registerRule()}
|
|
* as global one. As usual, global configuration overrides local one.
|
|
*
|
|
* The Rule can also validate file uploads, in this case the regular expression
|
|
* is applied to upload's 'name' field.
|
|
*
|
|
* The Rule considers empty fields (file upload fields with UPLOAD_ERR_NO_FILE)
|
|
* as valid and doesn't try to test them with the regular expression.
