Question

I have problem with JSON, passing html code, I don’t understand because I escaped with addslashes php function.

This is the JSON that fail:

With php JSON is valid:

<?php if(count($articles)): ?>
{"items":[
<?php foreach($articles as $key => $article): ?>
      <?php if($key==0  ):?>
      {
        "foto_g": "<?php echo $article->getRutafoto() ?>",
        "foto_th": "<?php echo $article->getRutathumb() ?>"

      }
    <?php else: ?>  
    ,
      {
        "foto_g": "<?php echo $article->getRutafoto() ?>",
        "foto_th": "<?php echo $article->getRutathumb() ?>"

      }
    <?php endif ?>  
<?php endforeach ?>
],
"nom_coleccio": "<?php echo $coleccio->getNom()?>"
,
"descripcio_coleccio": "<?php echo addslashes($coleccio->getDescripcio(ESC_RAW))?>"
}
<?php endif ?>  

And the result that have problem is:

{
"descripcio_coleccio": "<p>El delta de l\'Ebre ha estat l\'escenari d\'inspiraci&oacute; d\'aquesta col&middot;lecci&oacute;.</p>
<p>La l&iacute;nia de l\'horitz&oacute; i el color del paisatge materialitzats en alumini s\'uneixen per a crear volum en forma de joia.</p>"
}

When is the problem?

Thanks Regards

You should use proper encoding functions if possible. In case of JSON you should use json_encode, even if just for particular values.

But it would be easier if you collect the values in an array with associative keys and use json_encode only at the end:

if (count($articles)) {
    $items = array();
    foreach ($articles as $key => $article) {
        $items[] = array(
            "foto_g"  => $article->getRutafoto(),
            "foto_th" => $article->getRutathumb()
        }
    }
    $data = array(
        "items"               => $items,
        "nom_coleccio"        => $coleccio->getNom(),
        "descripcio_coleccio" => $coleccio->getDescripcio(ESC_RAW)
    );
    echo json_encode($data);
}
