[development] How to list fields and types

[Yves Chedemois]

This is D6 code for the CCK API.
In D7, you can use field_info_instances('node').

foreach (field_info_instances('node') as $node_type => $instances) {
   foreach ($instances as $instance) {
     $field = field_info_field($field_name);
     drupal_set_message(t('node type: %node_type, name: %field_name, 
label: %label, type: %type',
       array(
         '%node_type' => $node_type,
         '%field_name' => $field['field_name'],
         '%label' => $instance['label'],
         '%type' => $field['type'],
       ))
      );
   }
}
