Let's say, I have a text field which I use it as a phone number field. I set the number of values to unlimited, so people can enter more than one number.
However, I want to use another text field for the definition of that number. Such as:
Name Number
==== ======
Home 123456
OFfice 234567
Mobile 456789
How can I combine these two fields and require the Name field to be filled when each time a number field is created?
the easiest way is field_collection:
Provides a field-collection field, to which any number of fields can be attached.
A field collection is internally represented as an entity, which is embedded in the host entity. Thus, if desired field collections may be viewed and edited separately too.
You can make a compound field in code as this Phase2 Blog Post describes .... maybe there's a module for a compound field, but its usually not worth the effort.
You can also do this using the Double Field module:
Double field is a small module written to provide extensions to Drupal's core Fields. By this module you can divide your fields into two seporate parts.
For the moment it includes the following sub-widget types:
- Textfield
- Select list
- Single checkbox
- Textarea
