use encodeURIComponent in javascript before you assemble as JSON, and
then send it via post through the XHR.

use XMLHttpRequest.setRequestHeader(
"Content-Type", "application/x-www-form-urlencoded")

To set up your XHR for POST, then assemble the data you want to send in
this format:

"name=value&name2=value2&....nameN=valueN"

And where you would normally send null in your XHR, send the data instead.

The great thing about encodeURIComponent() is that all that translation
is done at the server level on most servers (all the ones I've ever
worked on), so once it gets to PHP, it should be okie doke.

If not, contact me privately (the email is in my sig), and we can talk
about the PHP side, this isn't the place for that.

All the best,
~A!

Just do the json_decode call first, and then do the sanitizing and
stripslashing and the like. That should solve your quotes problem.

Glad I could help!

Ok, can you send me a php snippet? Run the sig all together and
translate the at and dot, shoot me an email, I'll take a closer look.
