8. Manage Fields vs Manage Displays
• Manage fields
– Adding new fields
– Removing fields
– Grouping fields (with additional module)
• Order of the fields
• Setting labels display
• Setting fields contents display
• Again, grouping fields in groups (with additional
module)

9. Adding a date field to news
• Download/Install Date module
• Enable “Date”, “Date API” and “Date Popup”
• Go to
admin/structure/types/manage/news/fields
• Add a new field:
– Label: Original publish date
– Field type: Date
– Machine readable: “orig_pub_date”
– Widget type: Pop-up calendar

10. The date field
• Field settings:
– Date attributes to collect: leave it as it is, the
granularity is good to be by minutes
– Collect an end date: leave it as it is, we don’t need
to collect end date value
– Time zone handling: set to “No time zone
conversion”
– Cache dates: leave it as it is, we don’t need
caching for now

11. Advanced date field settings
• Required field: yes, we want to make sure the user has
filled in a value here
• Date entry options: set it as you prefer the format to
be
• Starting year: -0 years from now: we don’t really need
more time back
• Ending year: +0 years from now: we don’t need more
time ahead as well
• Default date: set it to “Now” as we want the field to
take current time by default
• Number of values: set it to “1”, as we need only 1
value

14. Adding an image field

15. Image field settings
• Allowed file extensions: the extensions the user can upload in the field:
jpg, png, etc
• File directory: used rarely, only if you want the field to store images in
specific folder which is not the sites/default/files folder
• Maximum and minimum image resolutions: used rarely, only if you want
to limit the input dimensions of the images
• Maximum upload size: this is the limitation you can set on the physical
size of the files
• Enabling Alt and Title: good to have if the administrator/editor has some
SEO knowledge to populate these meta data
• Preview image style: options come from Image style module. The size you
specify here is only for the back-end work of the admin
• Number of values: from 1 to unlimited, depending on the case
• Default image: rarely used, only if a feature or section requires an image,
you can set one default to be displayed when the admin does not upload
one

16. Adding tags field
• You can use the default existing Tags vocabulary field
• Use the ”Autocomplete term widget (tagging)” widget type
• Save and create with default settings

17. Adding tags field
• You can either use and existing Category vocabulary field or
create one (if the first one is not available) (1st screenshot)
• Use the ”Select list” widget type as you want the Category
field to be a list of values, only 1 of which can be selected
• Set the number of values to be 1, in the Category field settings
(second screenshot)

18. Compiling news content type feature
• We can export our News content type
configurations into code for better versioning
• Make sure you have the Features module
enabled and go to Administer > Structure >
Features > Create new
• Name and description of the feature are arbitrary
– anyway aim to specify them logically enough
you can remind yourself what the feature is
about
• You can start with 7.x-1.0 for the version

19. News content type feature
• Select “News” content type from the node
bundle components options
• Select all fields related to the news content
type from the Fields component: all that start
with “node-news-…”
• Download the feature
• Place the feature in your modules directory
and enable it
