How to change status programmatically

$node = Node::load(1827);
$node->setPublished(FALSE);
$node->set('moderation_state', "draft");
$node->save();

But... I have just found a bug where published content that is returned to draft status is still visible to anonymous users. Working on trying to find a known issue, if not creating one.

How to change user status?

Here's an example of how content moderation was implemented on a migration POST_ROW_SAVE event on Drupal 8: -

    public function onPostRowSave($row)
    {
      //Get this node ID from migration
      $rowIds = $row->getDestinationIdValues();
      $rowId = $rowIds[0];
      
      //Set the node to published including content moderation
      $node = Node::load($rowId);
      $node->setPublished(TRUE);
      $node->set('moderation_state' , 'published'); //Set content moderation flag to published
      $node->save();
    }

Hi

Not working for me as i tried below code. I'm using workbench moderation 8.x-1.2 version.
$node = Node::load(1827);
$node->setPublished(FALSE);
$node->set('moderation_state', "draft");
$node->save();

@haynescw try setting the moderation state to 'archived', which will unpublish the revision (assuming you have an 'archived' state). The draft moderation state doesn't actually unpublish latest revision, ie:

$node = Node::load(1827);
$node->setPublished(FALSE);
$node->set('moderation_state', "archived");
$node->save();

Or, to do more than one:

$nids = \Drupal::entityQuery('node')->execute();
$nodes =  \Drupal\node\Entity\Node::loadMultiple($nids);
foreach ($nodes as $node) {
  $node->setPublished(FALSE);
  $node->set('moderation_state', "archived");
  $node->save();
}

Drupal::entityQuery() can have conditions added to it to restrict the content types or anything else.

If you want to unpublish the nodes in array of content types programmatically, use following code in any of your .intsall file inside hook_update:

function pfe_brand_update_7002(){

$cont_types = array('article', 'page');
foreach ($cont_types as $type) {
$cont_nodes = node_load_multiple(array(), array('type' => $type));
foreach ($cont_nodes as $cont_node) {
$cont_node->status = 0;
node_save($cont_node);
}

}
}

Drupal 9:

Use following code
Unpublish :

	$nodesg->setUnpublished();
	$nodesg->save();

Publish :

	$nodesg->setPublished(TRUE);
	$nodesg->save();
