Unpublished node - database

Question

List with Views published nodes in the form of a table. Add to a table with a column that will contain a link. By clicking on the link ajax request should be sent, which makes the node unpublished.
I have views, have a link, have alert-ajax. But I don't understand how I can change the status from 0 to 1 programmatically.
My code in controller -
use Drupal\Core\Ajax\AjaxResponse;
use Drupal\Core\Ajax\RemoveCommand;
use Drupal\Core\Controller\ControllerBase;
class CustomAjaxLinkController extends ControllerBase{
public function customAjaxLinkAlert($node) {
$query = \Drupal::entityQuery('node');
$query->condition('status', 1);
$node = $query->execute();
$status = $node-> isPublished();
if ($status === TRUE) {
$node->status = 0;
$node->save();
}
$response = new AjaxResponse();
$selector = '.customAjaxLinkAlert' ;
$response->addCommand(new RemoveCommand($selector, $node));
return $response;
}
}
There is an error in it, but I cannot figure out what I am doing wrong

Answer 1

You can past data's via ajax in a Drupal Controller
$.ajax({
type: 'POST',
url: '/your_module/your_function',
data: {'data': data},
});
Then in your Controller
<?php
namespace Drupal\your_module\your_contoller;
use Drupal\Core\Controller\ControllerBase;
/**
* Class your_contoller.
*/
class your_contoller extends ControllerBase {
public function your_function() {
do what you want
}
}
OR
Your button is inside a form and will submit the value.
