get cf_id after submission CF V4

Hi,
I'm trying to post cf_id to a db table on form submission in V4. I've seen posts for this regarding V3 but can't seem to get it to work in 4.

This is what I've got:
in "custom code-after emails" (in controller mode):

<?php
$cf_id = $MyForm->tablerow["jos_chronoforms_rak_submit_copy"]->cf_id; 
rename("image_upload/upload_pic/marklandry.jpg", "image_upload/upload_pic/marklandry".$cf_id.".jpg");
?>

Hi Mark,

Please add a debug echo statement to make sure that you are getting the value of cf_id; and make the paths absolute rather than relative. Relative paths are too uncertain in Joomla! as you are never quite sure what the current path is.

<?php
$cf_id = $MyForm->tablerow["jos_chronoforms_rak_submit_copy"]->cf_id;
//debug code
$mainframe =& JFactory::getApplication();
$mainframe->enqueuemessage('$cf_id: '.print_r($cf_id, true).'<hr />');
// end debug code
rename(JPATH_SITE.DS.'image_upload'.DS.'upload_pic'.DS.'marklandry.jpg', 
  JPATH_SITE.DS.'image_upload'.DS.'upload_pic'.DS.'marklandry{$cf_id}.jpg');
?>

Hey Bob,
Thanx for your help.
Made the changes above (thanx also re paths🙂 )
the file is changed to "marklandry{$cf_id}.jpg"
and the debug info says something like "cf_id: "

Hi Mark,

I'm getting my versions mixed up :-(

In CFv4 the saved data is in $form->data[$model_id] and your model ID is probably the default 'chronoform_data' so please try

$cf_id = $form->data['chronoform_data']->cf_id;

or possibly

$cf_id = $form->data['chronoform_data']['cf_id'];

Bob

bummer, still the same results as before - ie, debug alert is empty and filename is appended to "marklandry{$cf_id}.jpg".
The model id number is the default...
Not sure what else could be wrong

any thoughts????

Hi Marc,

Does the system message from the debug line show that $cf_id has a value?

Bob

No, it just says something like "cf_id: "
