Sending HTML through JSON using AJAX

Question

I'm working with Mercado Livre API.

Since the user is allowed to use HTML in description field, I must allow it too. I'm using AJAX to communicate with Mercado Livre, but when I'm trying to parse a big HTML code, I'm not able to use json_decode on PHP.

How can I encode the user's HTML before sending it to PHP and decode it when it's received?

Answer 1

You first, require encode all HTML and next send this to API, for this, you can use the next function:

var encodedHtml = originalHtml.replace(/[\u00A0-\u9999<>\&]/gim, function(idx) {
  return '&#'+idx.charCodeAt(0)+';';
});

This code is on side client. To decode HTML in your server side, you need the use html_entity_decode PHP sentence.

I hope this help you.
