I have trouble while rendering display article for look beautifull. Saving article have sanitize with used trim(stripslashes($article));

And I want to display article use HTML code by parse saving before, the goal is easy and comfort to read article.

in Article controller

public function view($id = null)
    {
        $article = $this->Articles->get($id, [
            'contain' => ['Users', 'Comments', 'Tags']
        ]);
		$parsearticle = $this->Articles->find()->extract('Isi');
		return $this->response
			->withType('application/json')
			->withStringBody(json_encode([
				'parseHTML' => $parsearticle,
			]));

        $this->set('article', $article);
    }

in method
public function beforeMarshal(Event $event, ArrayObject $data, ArrayObject $options)
 {
   foreach($data as $key => $article) {
	  if(is_string($article)) {
		$data[$key] = trim(stripslashes($article));
	  }
     }	
   }

in ctp

<div id="parseHTML">
</div>
<p>
   <?php echo $this->Text->autoParagraph(h($article->Isi))."\n"; ?>
</p>

<!-- parser HTML -->
<script type="text/javascript">
 jQuery(document).ready(function() {
   var tampil = $("#parseHTML");
   var parse = '<?= Router::url(["controller" => "articles","action" => "view"]); ?>';
   var konv = $.parseHTML(parse);
   
   $.ajax({
      type:'post',
	  url:parse,
	  data:'&type=parseHTML',
	  dataType:'json',
	  success:function(){
		tampil.append(konv);
	});
  });
</script>
<!-- //parser HTML -->

Do you want to save a WYSIWYG html content?
If yes, you shouldn’t use stripslashes. You can use HTML purifier and simply echo the output.

If you want just to show the plain text as paragraph then don’t use stripslashes, just autoParagraph

I don’t understand the error message

really that’s running good, not error, just display JSON.

I have read tutorial on
https://discourse.cakephp.org/t/how-to-make-simple-jquery-ajax-in-cakephp-3-7/5834

and

in ctp
the logic that I’m expect is value of variable $article->Isi
send to jQuery to parse HTML formated

<div id="parseHTML">
</div>
<!-- parser HTML -->
<script type="text/javascript">
 jQuery(document).ready(function() {
   var tampil = $("#parseHTML");
   var parse = '<?= Router::url(["controller" => "articles","action" => "view"]); ?>';
   var konv = $.parseHTML(parse);
   
   $.ajax({
      type:'post',
	  url:parse,
	  data:'&type=parseHTML',
	  dataType:'json',
	  success:function(){
		tampil.append(konv);
	});
  });
</script>
<!-- //parser HTML -->

but the goal, doesn’t I’m expect. I wanto view article there’s formated HTML content identation, paragraf, align justify, bold and underline. For easy to reading

So, you have formatted HTML in your database, and you want to display it that way in the view? Why can you not just output exactly what you read from the database?
