http://phocoa.com does combines them.
"binarycloud" mentions Smarty and Propel on the website
but I am not if/how they combine them.
Form generation is an interesting feature -- especially for
prototyping. It's my experience that in "real" project where a
designer is involved, form generation is not of much use.
Actually, I am thinking about a way to "extend" a generated
HTML page; backed up by a algorithm that
identifies new data-columns the user has to fill in but are not
provided in the HTML page yet. This could be interesting for
automated front-end testing, too. But at the moment it's just
an unadjusted idea of mine :-)
I will outline how I use Propel/Smarty (assuming that more
experienced programmers would do it in another way):
At the moment I am using the Propel-validator mechanism
to validate data entered by the user, since from my point of
view the model-objects should in-/validate themselves.
To accomplish this I added my own BaseClass with a "clever"
isValid()-method to validate an model-object.
a) In the Controller all properties/columns of the model can be
checked at once like this:
if($m_model->isValid(NULL) == FALSE)
{
// There is one or more invalidate properties/columns
// in the model.
$smarty->assign("model", $m_model);
}
else
{
// Everything is OK.
$m_model->save();
}
b) In the template each colum can be checked on its own:
{if $model->isValid('username') == FALSE}
// Display some big, red, blinking icon nect to the username-textfield.
// But: model->isValid('username') will return TRUE iff
// the formular is a "fresh" one and the model hast no been
// check beforehand. So, this works for newly created models (INSERT)
// as for models retrieved from the database (UPDATE).
{/if}
c) In the error-template all error-keys of the Propel-validators
are looked up in a smarty-configuration file:
{foreach from=$ERROR_KEY_ARRAY item=ERROR_KEY}
// The ERROR_KEY may be 'username_invalid_chars' and will
// be translated to 'The username you entred contains invalid chars.'
{$smarty.config.$ERROR_KEY}<br/>
{/foreach}
