Background: I'm writing a module that will hopefully make reverse-engineering specs for site audits easier. (If you're interested, you can see the Topograph module-in-progress on my Github account.)

Basically it's a bunch of byzantine views that use custom handlers to pull things like serialized data out of the DB to display stuff like nodetype settings to the admin user.

I'm having a lot of trouble finding certain things, though. Fieldset info is a major one, as well as settings like whether the field is required. I'm not finding it in the blob of data pulled from the {field_config_instance} table (though I might be overlooking it). Can someone point me to where this info can be retrieved per nodetype/field instance?

i think field_config_instance for example only has like the required setting, if the parent field element options are altered in any way for a bundle (because fields can exist in many bundles) ... so i'm not sure you can rely on looking at 1 SQL table. thats why field_get_info() exists. –  tenken Aug 21 at 23:12
 
That function doesn't seem to exist, and the closest thing I could find, field_info_field(), doesn't seem to have fieldset or required info in the return value. –  beth Aug 21 at 23:23
 
Does it have to be DB, or can you do it via the API? –  MPD♦ Aug 21 at 23:25
 
Via the API works fine too. –  beth Aug 21 at 23:25
 
field_info_instance() should do it, the 'required' setting is under 'settings' in that array. By fieldset info do you mean the stuff field_group provides? If so that's in the field_group table. If you're looking at the db structure in a GUI it's easy to miss the field_group table, it gets buried in amongst the field data/revision tables –  Clive♦ Aug 21 at 23:33

Whether a field is required or not can vary by content type (ie, the bundle). I am pretty sure you need to use field_info_instances($entity_type, $bundle_name). You can then use field_info_field($field_name) on the results. Something like:

$fields_info = field_info_instances('node', $bundle);

foreach ($fields_info as $field_name => $instance) {
  $field_info = field_info_field($field_name);
}

dpm() both the $instance and $field_info. Everything you need should be in those two variables. This is a snippet from a dynamic exporter I have.

I will note as a comment, that I am not positive that the fieldset info is in there. –  MPD♦ Aug 21 at 23:35

Fields don't have any related fieldset info as such, some modules (e.g. field_group) provide them but they're stored separately (in a table and as ctools exportables) –  Clive♦ Aug 21 at 23:38
 
That makes sense. I hardly every use groups. –  MPD♦ Aug 21 at 23:43
 
Neither fieldset nor required info is provided by field_info_instances() or field_info_field(). Clive, if you can tell me where field_group stores fieldset info, please do. I can't find it. –  beth Aug 21 at 23:46
