fields

We wanted to add a functionality to our file widget so it could register when to exclude a file from search results. Files are indexed and searched with apachesolr and tika. So our idea was to add a checkbox to the file widget and save its value. A hook apachesolr update index will then know if a file can be put in the index or not. We ll save the exclude as field in the file_managed table.

When you query your entities on values on a field, for example you want to get all nodes via a node reference field. In our case we have an event and we want to know all referenced sessions to it.

If you want to render only one field of your entities you can in drupal 7. Here in the example we have an entity called model which contains an image field.

To render the field you have to specify to the field_attach_view function which entity type, the entity and the view mode you want to use. The function returns a renderable array.

If you want to save only a specific field on your entity instead of saving the whole entity you can. In a submodule of the fields module you ll find a module called field_sql_storage module. In that module all functions available for the sql storage backend can be used.

This small drupal 7 tip will help you get out values from entity objects, like nodes, users, taxonomy, ...

You probably seen this data structure when loading nodes:

A cck fieldgroup can be rendered alone. We had some quicktabs we wanted to fill with our field groups. So we've builded a block for each field group to put in the quicktabs. Here is an example of one block where we called a single fieldgroup and rendered it.

How to add another formatter to a cck field? A cck formatter is basically a theming function where the value of field is ran through. Formatters are available at "admin/content/node-type/[your node type]/display" in the cck interface.
