In the site, which I develop, I need to have workers, who provide specific services. Each worker for specific services has their own prices. Workers are drupal users, Services are drupal taxonomy terms of vocabulary services. For users I have created term reference field (called field_services) with the multiselect check boxes widget.
In the user edit form, when services are selected, I need to show additional textfield (price) for each service, how can I achieve that? Is it possible to do that with field collection, because I didn't succeed. Or should I use hook_form_alter and create a column in table field_data_field_services of my drupal database? Thanks for the help.
