[TYPO3-dev] mailform using cObj->FORM in own extension

[Michael Leupold]

Hi,

this is my first post to the list, though I'm not really new to typo3. 
Sorry if the question I ask is stupid or answered somewhere else, but 
after googling and digging the archive for several hours I thought I'd 
try my luck.
I'm trying to develop a small extension for one of my customers. It's 
basically just an event list with options to book events. Booking is 
planned to be "very simple" - by emails sent out to the customers. And 
that's where my trouble starts.

I put together a form in my extension's setup.txt:
------------------------------- zip here -------------------------------
plugin.tx_leuseminareregistration_pi1 {
   anmeldungForm < tt_content.mailform.20
   anmeldungForm.locationData = 1
   anmeldungForm.redirect >
   anmeldungForm.redirect = 65
   anmeldungForm.method = POST
   anmeldungForm.accessibility = 1
   anmeldungForm.dataArray {
       1.type = subject=hidden
       1.value = Anmeldeformular
      
       30.label = Nachname
       30.type = nachname=input,40
       30.required = 1
      
       40.label = Email
       40.type = email=input,40
       40.required = 1

[... just some more form fields ...]
      
       140.type = formtype_mail=submit
       140.value = Anmelden
   }
   anmeldungForm.recipient >
   anmeldungForm.recipient = name at domain.tld
   anmeldungForm.layout = (some layout)
   anmeldungForm.REQ = 1
   anmeldungForm.REQ.layout = (some other layout)
   anmeldungForm.LABEL.layout = (again some other layout)
}
------------------------------- zip here -------------------------------

Please note that I thought were unneccessary to quote. I then load the 
form up somewhere in my extension script as follows:
------------------------------- zip here -------------------------------
// put some database content here
$conf['anmeldungForm.']['recipient'] = $row_seminar["email"];
// build an array to render the form to my template later
$totalArray["###FORM###"] = $this->cObj->FORM($conf['anmeldungForm.']);
------------------------------- zip here -------------------------------

I use this so I can modify hidden fields with database content (eg. 
$conf['anmeldungForm.']['dataArray.']['30.']['value'] = 
$row_seminar["some_column"];). Later I render the form somewhere into my 
template. And indeed it gets displayed just fine (with db-content). On 
submitting the redirect-page is loaded. The problem I have is that I 
don't get any email - and I don't get why I don't get any email.
Do I have to handle formmailing somewhere myself in my script or is 
there a way to use the built-in formmailing capabilities? Just as a 
note: Sending emails from "usual" form content-elements works fine.

I'd really appreciate any little push into the right direction.

Thanks for your time,
Michael
