Catch PrestaShopException in ajax

[Amazzing]

Hi everyone,

 

I am updating a product using an ajax request.

 

The php code is really basic:

$product = new Product($id);
$produc->description[$lang] = $new_description;
$product->save();
...
die(Tools::jsonEncode($result));

But if for any reason product is not saved, function stops executing and I get an ajax error.

 

For example, I have included an iframe in $new descrpiption for purpose. And I don't allow iframes in prestashop settings. So, if I call that ajax file directly from browser with same params, I can see that there is a Prestashop exception 'Property Product->description is not valid'.

 

So, how can I catch this kind of error, and show it to user?

 

Of course, I can validate the $new_descrtiption before saving the product. But first: in this case, validation code will be executed twice. Second: I am planning to save different fields, so a lot of validation rules have be hardcoded thus making code less adjustable to prestashop updates
