How to list all the authors for different books' section or subsection?

you should always specify which version of drupal you're using. i think normally these kinds of questions are put in the regular drupal forum. but seems OK here?? not sure. i'll answer anyway.

i'm going to assume you're using D6, and also the latest version of the views module.

views helps you make lists, so a list of authors would be a case where you need views.

I just tested this out and it worked, so you should be good to go. Write back if you have trouble.

To make a list of book authors with Views module:

• Go to views editing screen admin/build/view - add a new view of the type 'node'
  • see the views editing page load, there are 4 columns. in 1st column, note the word 'default'. for now we're just editing the default options. note the columns to the right. locate options to edit 'fields' in 3rd col. and 'filters' in 4th col.
• in filters: 4th column, use the + sign to add a filter
  • note: the options to edit appear below this window, so scroll down. you will need to make changes and click 'update after each change.
  • select Node: Type = Book page
• in fields: 3rd column, use + sign to add a field
  • select User: Name Name
  • after you select you will see options. choose both:
    • [x] Exclude from display
    • [x] Link this field to its user
• in Basic settings, 2nd column,
  • make sure it is Style: Unformatted, click to select and change it.
  • click the grey 'gear' to the right of 'Style Unformatted', to change settings.
  • scroll down to where you see 'Grouping field:' ... select "name", click update...
• now when you scroll down you see a list of your authors for the books.

To add the block: In the 1st column, add a display, select 'block' and add display. when you go to /admin/build/blocks you will see your new block available, and you can select it to add to the left sidebar or change where it appears.

Thank you very much, heather. I know you extract author name according to node. I want to display author's user name one time even though he/she wrote many chapters or sections on many nodes. And there are 6 or more books, and I want to display different author list for different books. May you figure it out? Thanks a lot!

ah.. no i don't know...

oh i missed the point that you wanted book-specific authors... and i suppose you want the list to appear in a sidebar on both the parent and child pages of a book?

yeah the above will list each author once, but for all your books.

sorry i don't know how to do what you need.

good luck in your search, please post back if you find something.

i'm curious now!
