In CFV<6 it was possible to remove a variable from the $form->data array by using unset.
I tried the same in CFV6 to no avali:

$this->data['myfield'] = "foo";  // this works

unset($this->data['myfield']);  // not working

I created a simple test form and I'm not sure what is happening. The setup:

a form with a textbox (myfield) and a submit button.

In the submit event I put a php action and a debugger.

If I put the 1st line of the above code in the php action the result is:

Array
(
    [option] => com_chronoforms6
    [cont] => manager
    [chronoform] => myform
    [event] => submit
    [myfield] => foo
    [button] => 
    [_ga] => GA1.2.561620972.1461746531
    [cookiesDirective] => 1
    [300gp] => R393630445
...

If I put both lines the result is:

Array
(
    [option] => com_chronoforms6
    [cont] => manager
    [chronoform] => fmyform
    [event] => submit
    [myfield] => a value
    [button] => 
    [_ga] => GA1.2.561620972.1461746531
    [cookiesDirective] => 1
    [300gp] => R393630445
...

Anyway what I want to accomplish is this: How can I edit uploaded files in a form?

I edit a form and don't want the file upload field to be updated when it is not changed.

Thank you

In order to manage the editing process of uploaded files I don't understand the way CF builds the html code.

If the ghost value is set for the file field, when loading a record the ghost input element value is set to the file name.
But when i submit, this value is not submitted because the ghost value input is before the file field input. And if I don't select a file, the submit event receives an array with an empty value.

So the ghost value is not useful.

Or, as ussual, I'm missing something.

The "problem" affects file fields used in a repeater.

My setup:

- repeater
- file field in the repeater with Multi file select property set to No
- file field name property: myfile[{var:area_repeater5.key}]

I put a debugger in the submit event before the upload file action and one after it.

Before I get:

[myfile] => Array
        (
            [0] => 
        )

After:

[myfile] => Array
        (
            [0] => 
        )

If I use a file field outside a repeater and without [] in the name I get a different behaviour:
Before :

[myfile] => 

After:

[myfile] => afilename

Is there something wrong in my setup?
