Re: [PEAR] QuickForm element group validation question

In your "addGroup()" call, I think you might want to set a name for your
group but set the $appendName parameter to false. I think that'll do
what you want it to do. Keep it flat but still referencable inside the
addGroupRule() function.

see the description of the parameters for the addGroup() rule at the
following url.

Brilliant! I wasn’t aware that that parameter existed. Thanks!

Hi,

I have a question about validation when grouping elements in an
HTML_Quickform. Here's the situation:

I have a quickform that has a subset of elements that are grouped using the
$form->addGroup() method. After the user submits the form, I have a
function that iterates through the values in the $_POST array and uses that
information to construct either an update or insert statement that gets sent
to the db. This function, at present, requires that the values in the
$_POST array are "flat", ie no nested arrays. When you leave out the name
parameter to the addGroup function, it doesn't create nested arrays when
filling out the $_POST array: it's flat, which makes me very happy.

The problem arises when I try and validate one of the elements in a group.
The normal addRule() method doesn't appear to work when you simply give it
the grouped element name as a parameter. The addGroupRule() function works
as advertised, but you need to pass it a group name, which means that I have
to give my addGroup() calls a name, which means I no longer have flat $_POST
arrays. When I leave out the group name from the addGroupRule I get a weird
error about not finding HTML_QuickForm_Header::getElementName in
QuickForm.php line 1051. I expect I'm not supposed to do that.

I'd really rather not make my $_POST iterator function smarter to deal with
nested arrays unless I have to. Does anyone have any suggestions as to how
I can get the look and feel of element groups (an advcheckbox and a text
element side-by-side), allow validation of one of those elements (the text
element), and get a flat $_POST array?

Thanks in advance for any help,
LJ
