Question

How do I find all nodetypes containing a particular field?

Suppose for example I have two nodetypes, “mybio” and “myresume”, and both nodetypes contain a field “myphoto”. Is there a function that takes the name of my field as input (“myphoto”) and returns the names of the nodetypes containing this field (“mybio” and “myresume”)?

Answer 1

I don’t think there is a function but looking at the database structure for CCK something like this would do the trick:

function content_field_get_node_types($field_name) {
  $query = db_query("SELECT DISTINCT type_name FROM {content_node_field_instance} WHERE field_name = '%s'", $field_name);

  $node_types = array();
  while ($row = db_fetch_array($query)) {
    $node_types[] = $row['type_name'];
  }

  return $node_types;
}
