1.
The forms I generate with HTML_QuickForm cannot be submitted. When I look at the
page's HTML source, I see something like <formArray>.
Recent versions of HTML_QuickForm package require HTML_Common package version 1.2.1
(CVS revision 1.8 in HTML/Common.php) to work properly. If
(and only if) an older version of HTML_Common is loaded, these symptoms occur.
Please note that
command may tell you that you
have HTML_Common 1.2.1 installed.
In this case you also have an older version of HTML_Common somewhere and are including it instead
of the proper one. Check your
include_path setting in
php.ini
and/or use PHP's
get_included_files()
function to find out which file you are
really including.
2.
When I pass some GET parameters to the script containing a form, QuickForm thinks
that the form was already submitted, displaying validation errors.
Constructor
of HTML_QuickForm accepts a $trackSubmit parameter.
Setting this to TRUE will make QuickForm check whether the form was actually submitted.
This also helps if you have several forms defined on one page.

How do I set default/constant values for 'date' element?
Date element is essentially a group
of selects, you define the structure of this group
in the 'format' option when
creating the element:
$form->addElement('date', 'foo', 'The date:', array('format' => 'Y m d')); |
Thus you pass the defaults as an array, just like you do with any other group:
$form->setDefaults(array(
'foo' => array('Y' => 2004, 'm' => 9, 'd' => 29)
)); |
To ease using it with database-backed applications, date element also accepts Unix timestamps
(generated by mktime()) and
strings. The strings are processed by strtotime()
functions, so consider its limitations.

I receive weird "Call to a member function on a non-object"
or "Undefined function" errors, especially when dealing with groups.
These errors tend to appear when you have something which is not a
HTML_QuickForm_element in the $elements array
passed to addGroup().
This "something" is usually either a PEAR_Error instance (check for these
or setup a handler) or, if register_globals is switched on in php.ini,
some submitted values (clear the array before adding elements to it).
