Prestashop WebService API - save in database HTML rich text - php

Question

I am developing a php manager for prestashop via webservice. I have a module created to keep notes about orders.
From the management program I have a form with TinyMCE. But I can't save the text when it has HTML tags
webService class in prestashop module
class sellerNotas extends ObjectModel {
public $id;
public $id_seller;
public $nota;
public static $definition = array(
'table' => 'seller_notas',
'primary' => 'id',
'fields' => array(
'id' => array('type' => self::TYPE_INT),
'id_seller' => array('type' => self::TYPE_INT),
'nota' =>array('type' => self::TYPE_HTML, 'lang' => false, 'validate' => 'isCleanHtml'),
)
);
protected $webserviceParameters = array();
}
MySQL TABLE
I have no problem saving plain text without labels, the problem is when the text has labels.
I have tried htmlentities with no correct results.
create note php function

Answer 1

Please make sure you have used CDATA for that HTML node so it not get break due to any any component
$node = dom_import_simplexml($resources ->nota);
$no = $node -> ownerDocument;
$node -> appendChild($no -> createCDATASection($nota));
$resources ->nota= $nota;

Answer 2

SOLVED WITH htmlentities PHP CODE:
static function nuevaNota($idVendedor, $nota, $tienda) {
try{
$webService = webService::webServiceTienda($tienda);
$opt = [
'resource' => 'seller_notas?schema=blank'
];
$xml = $webService->get($opt);
$resources = $xml->seller_notas->children();
$resources->id_seller = intval($idVendedor);
$resources->nota = htmlentities($nota);
var_dump( $resources->nota);
$opt = [
'resource' => 'seller_notas',
'postXml' => $xml->asXML(),
];
$createdXml = $webService->add($opt);
}
catch (PrestaShopWebserviceException $e){
webService::controlErroresTienda($e, $tienda);
}
}
