wix forms seems to support custom CRM fields, and can properly map to them, but in practice the custom fields do not seem to update via form submission. I think this has been acknowledged as a current bug in wix-forms.
I know the answer is to use custom code to call getContact( ) in crm-backend, but I’m at a loss as to the practical implementation here.
- Provide a members-area form to manually submit data which will be inserted into the member’s CRM custom fields.
- If this data already exists, populate it as the example text in the form for the user to update.
