Question

I want every user, that registers on my Magento instance, to upload a certificate that shows me that he registered a business.

I already added the fields in the template. But how can I fetch the file and save the filename / contents in the customer record?

Is there a way to extend the functionality in the Controllers?

This is actually even easier:

Just make sure you set these parameters on your config.xml:

            'attributes' => array(
                'prooffile' => array(
                    'type'          => 'text',
                    'input'         => 'file',
                    'label'         => 'Proof file',
                    'visible'       => true,
                    'required'      => false,
                    'position'      => 100,
                    "user_defined" => false,
                ),

This adds a nice editor in your admin backend.
