QuickForm (QF): trouble with a group of 'file' elements and group rules

greetings, *please* CC me on any replies as I am not currently subscribed to the pear-general list. thank you. I have the following bit of code (with some things removed) that I am attempting to get working: -- begin code --- $form = new HTML_QuickForm("foo", "post", null, null, array("mimetype" => "multipart/form-data")); $form->addElement("header", "header", "example header"); $images = array(); for ($i = 0; $i < 10; $i++) { $images[] = &HTML_QuickForm::createElement("file", "", "Image {$i}"); } $form->addGroup($images, "images", "Images", "<br />"); $form->addGroupRule("images", "File size must be less than 512kilobytes", "maxfilesize", 512000); $form->addGroupRule("images", "File name must be *.jpg or *.jpeg", "filename", "/\.[jpg|jpeg]$/"); $form->addGroupRule("images", "File must be of type jpeg image", "mimetype", array("image/jpeg")); $form->addGroupRule("images", "File must be uploaded", "uploadedfile"); --- end code --- I expect the following to happen against the 'images' group given the rules I've set up: - the files must be of mime type image/jpeg - the files must be less than 512000 bytes in length - the files must end with jpg or jpeg I read an article (http://www.midnighthax.com/quickform.php) that told me to use "True" as the last argument in the process() method call because file elements are involved. I've done that. now, at least, I get an array of files, however QF does not error when I upload a gif image instead of a jpg. even if I have the regexp set up incorrectly, the mimetype check should cover me, but it does not. the code sails through to the processing method I've set up without a hiccup :( one of my revisions of this code tried to add an element rule for the 10 elements inside the foreach. this did not work, so I tried it with a grouprule() call instead, and I'm having similar troubles with rule enforcement. I've decided to ask the list before I go down another dead end attempt at a solution. note that during the processing phase, it looks like I'm getting appropriate information from QF. are element names such as "image[0]" and "image[1]" for the file elements common in this sort of application considering I am using groups? will that cause QF to have trouble enforcing the GroupRules? any assistance with this issue is appreciated. again, please CC me on any replies as I am not currently subscribed to the pear-general list. thank you. regards, J
