yes.
looking your answerwe are using a contact form for requesting a download to send an email to the photograpministrator (kind of) and that visitor himself. technically the visitor can change the field content.
at that time, when the short code is built, we are looking for the photographers mail address.
looking for your answer.
Is it possible to use this funtionality with hidden form tags/fields. I can make it only with visible input fields.
Yes, it is possible with the hidden
form-tag type.
Can I lock visible fields for input?
This has nothing to do with shortcode attributes, but some form-tag types support the readonly
option. I guess it is what you are looking for.

Hi.
Thank you. The hint with the hidden field showed me the right direction. Though there is now an error in the contact form setup, because of a mismatch in the email settings. But it works excellent.
