How to update the node status?

Question

I'm using data from JSON to create new nodes or update fields on existing if node exist on my Drupal 8 website. So, when I use method to update nodes, I need to save in array node id of updated nodes and keys of fields with changed values in this node.

After update is finished I need to print table with all nodes of this content type where fields of updated nodes need to have different style (color, background, etc).

So if my old node have body = "body1" and description = "description 1" and new node have body = "body2"and description = "description 1" after update is finished i need to get output like this:

Here is an example:

$node = \Drupal\node\Entity\Node::load($nid);
$node->set("body", 'New body text');
$node->set("description", 'New value');
$node->save();

Any suggestion?

Note: when I use $node->save(); if all updated values is same nothing is changed (date of node in content from admin panel is same as before update), but if values is different I need to store node id, keys and values only of changed fields in array.

Answer 1

To set the status you can use the setPublished() method:

public function Node::setPublished

Sets the published status of a node..

Parameters

bool $published: TRUE to set this node to published, FALSE to set it to unpublished.

In your case:

$node = \Drupal\node\Entity\Node::load($nid);
$node->set("body", 'New body text');
$node->set("field_name", 'New value');
$node->setPublished(TRUE);

Answer 2

Do you save a new revision of the updated node? Maybe you can use the diff module to see the changes between the current & previous node? This is not an in depth solution, but maybe could be useful pointer for you.

Don't forget the node->save() or your node changes will be ignored.

$node = \Drupal\node\Entity\Node::load($nid);
$node->set("body", 'New body text');
$node->set("field_name", 'New value');
$node->setPublished(TRUE);
$node->save();
