(
    [articolo] => Array
        (
            [name] => 23_Errori_dmb.docx
            [original_name] => Errori_dmb.docx
            [path] => articoli/201512040927_645_23/23_Errori_dmb.docx
            [size] => 13536
            [link] => articoli/201512040927_645_23/23_Errori_dmb.docx
        )

    [foto] => Array
        (
            [0] => Array
                (
                    [name] => 23_dmb_contatti.png
                    [original_name] => dmb_contatti.png
                    [path] => articoli/201512040927_645_23/23_dmb_contatti.png

                    [link] => articoli/201512040927_645_23/23_dmb_contatti.png
                )

        )

)

Uploaded one file "articolo" and two file "foto"

I used this custom code for "Articolo" but it doesn't work..

<?php
$form->data['articolo_url'] = $form->data['_PLUGINS_']['articolo']['link'];
?>

How can I solve??😟

Hi GreyHead,
this code works fine for the

<?php
$form->data['articolo_url'] = $form->files['articolo']['link'];
?>

and this code works for multiple upload

$form->data['file0_url'] = $form->files['foto']['0']['link'];
$form->data['file1_url'] = $form->files['foto']['1']['link'];

thanks
