This is a message I received privately. I post it here because it could help

That's ok. Use single quotes when possible.

There is no need for that.
You don't want to set default values if the form is posted. You only set
default values when the form is displayed for the first time. Also, there is
no need to set default values if they are empty. setDefaults() is made to
fill a field with default values when it is displayed.

Use : $form->addElement('text', 'date', 'Date:');
You are wrong in the parameters order.
addElement is supposed to be used this way:
addElement( element type, element name, element label );
You can have more parameters. It depends on the type of element you use.
I will have to write a documentation for each element one day. For instance,
for a textfield, you can have:
Use : $form->addElement('text', 'date', 'Date:', 'size=12
maxlength=8');
This will had HTML attributes to your element.

> 'File:');
Same here, use:
$form->addElement('file', 'fileUpload', 'File:');
> $form->addElement('submit', '', 'Submit');
$form->addElement('submit', 'submit', 'Submit');
is better. ^ type ^ name ^ label
> $form->addRule('date', 'Please type in a date', 'required');
This is fine. You could also do:
$form->registerRule('dateRule','regex','^\d{1,2}(\-|\/|\.)\d{1,2}\1\d{4}$');
and then,
$form->addRule('date','Your date is not
correct','dateRule','', 'client');
Adding client at the end create the necessary javascript for client-side
validation. Server side validation is always enabled in case users disable
javascript on their browsers.
registerRule is very helpful if you want to create your own validation
function. For instance, you could create a function which check in the
database if the username the user chose is already taken and return true if
the username is free or false if it's taken. Then QuickForm would call this
function at validation time (server-side of course) and display the error
message if the function return false.
$form->registerRule('checkName','function','checkName');
function checkName($element, $value) {
// code for username validation
}
and then,
$form->addRule('username','Name already
taken','checkName','function');
In the case of a regular expression you are not forced to register the rule
first. You could directly write :
$form->addRule('date','Your date is not
correct','regex','^\d{1,2}(\-|\/|\.)\d{1,2}\1\d{4}$', 'client');
Remember that addRule takes its parameters this way:
addRule($element, $message="", $type="", $format="", $validation="server");
and if type is 'function', the rule will need to be registered first.

I guess the rest should work fine. Please tell me if it works so I can make
sure everything is fine. Thanks.
