[TYPO3-project-formidable] Executing Javascript just before submitting (handling multi pages forms)

[mperrin at stratis.fr]

Hi,

 

First of all, I would like to thanks the developers of the Formidable
project. I have been testing this extension since yesterday, and I think
this is an incredible way to design forms. I am happy to find on the Typo3
API some habits I had with PEAR (formbuilder, dataobject
).

 

With the help of the documentation by example, I started to test the
functionalities of this API and I tried to implement a multi page form.. and
I have some questions :-)

 

1/ I wonder if there is a way to execute some javascript just before
submitting the form depending on the submit button pressed. 

 

2/ In fact, I am looking for a way to handle multiple form pages. The way I
do is very simple :

-          2 submit buttons : back / next

-          1 hidden input element named step

-          Save form data in session when submitting the form before the
final step

 

I just want to change the value of the hidden input element depending on the
submit button pressed.

 

So I added an onclick event handler on the submit button. 

 

However, doing this seems to disable the submitting of the form. A look at
the API in the file class.tx_rdtsubmit.php confirms that behavior:

 

$sEvents = parent::_getEvents();

                        if($this->oForm->_navConf("/onclick",
$this->aElement) === FALSE) {

[
]

}

return $sEvents;

 

So I tried to concatenate the onclick value with the form submitting action:
$this->oForm->oRenderer->_getFullSubmitEvent() (hack of the
class.tx_rdtsubmit.php file)

 

This works, but now, my data handlers are not executed.

 

So my question: is it the good way to proceed?

 

Best regards,
