[SOLVED] Drupal 7 Does "New Node Creation" initiate/prepare the Fields for different Content Types?

Drupal 7 Does "New Node Creation" initiate/prepare the Fields for different Content Types?

In Drupal 7, i need to Programmatically create the Nodes. As usual, there are Different Fields set for Different Content Types.

For very simple example:

Content Type: "car"
Fields: "Model", "Engine", "GearType"

Content Type: "article"
Fields: "Title", "Author", "Media"

What i want to be confirmed here is, while i am creating a new node, for e.g by using:

$node = new stdClass();
$node->type = "car";

Then..

Is that (currently creating) new $node has been initiated/loaded with its related/corresponded fields, already before get saved?
To be more clear, if i just suddenly Save a node node_save($node) (without filling any other related fields) will that node be still having (following) its proper Content Type structure?

Solution

I think this is what your looking for:

$node = new stdClass();
$node->type = 'article';
node_object_prepare($node);
