|

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

|
|
* The Rule needs one configuration parameter for its work: the size limit.
|
|
* This limit 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.
|
|
*
|
|
* Note that if file upload failed due to upload_max_filesize php.ini setting
|
|
* or MAX_FILE_SIZE form field, then this rule won't even be called, due to
|
|
* File element's built-in validation setting the error message.
|
|
*
|
|
* The Rule considers missing file uploads (UPLOAD_ERR_NO_FILE) valid.
