Hi,

In Drupal 8 I am able to create new nodes, but I cannot figure out how to populate a field referencing taxonomy terms.

$edit_node = array(
...
'field_category' => array('x-default' => array(array('target_id' => 48, 'target_type' => 'taxonomy_term')));
...
);
$node = entity_create('node', $edit_node);
$node->save();

The node is created, but I see no traces of the terms in the database.

I have also tried replacing 'x-default' with the actual language code, and I think field_category is mostly correct because I have been debugging ContentEntityStorageBase and I can see it examining the field. But I can't figure out why the values are not getting persisted.

Can anyone give me a hint ?

It turns out that the langcode wrapper should not be there. Nor is the target_type needed.

'field_category' => array( array( 'target_id' => 48 ) )

//Add this in the top of the file you are using.
use Drupal\node\Entity\Node;

//Where you add node.
$category_id = 1;
$node = Node::create(array(
'type' => 'Node_bundle_machine_name',
'title' => Node_title,
'langcode' => 'en',
'uid' => '1',
'status' => 1, //1 means published
'field_text' => array(
'value' => 'String of text,
),
'field_category_reference' => array(
array( 'target_id' => $category_id ),
),
));
$node->save();

'field_category' => $tid,

Adding above mapping in $node array like other fields will populate term reference field.
Hope this helps.
Thanks!!

This shorter code works perfectly. Thank you all :-)

How would this work if you wanted to add multiple taxonomy terms?

I'd also be interested in how to do this for vocabs that have been configured to ...
"Create referenced entities if they don't already exist"

I know could do this in D7, but I'm hoping someone could share a quick lead for D8 so I don't have to go on spelunking exercise

Thanks!
Matt

I have not found a way for that to work, but I did find that this worked great.

$cat = 'term name that you want to add';
$terms = taxonomy_term_load_multiple_by_name($cat);
$ctids = array();
if($terms == NULL) { //Create term and use
$created = _create_term($cat,'nog_quote_cats');
if($created) {
//finding term by name
$newTerm = taxonomy_term_load_multiple_by_name($cat);
foreach($newTerm as $key => $term) {
$ctids[] = $key;
}
}
}

Then add that new $ctids in the node create

function _create_term($name,$taxonomy_type) {
$term = Term::create([
'name' => $name,
'vid' => $taxonomy_type,
])->save();
return TRUE;
}
