Backbone.js: the save method always returns a callback error

I know that people are probably embarrassed why I don't use rails , but I use php better, so I chose it. I am basically trying to create a really simple backbone.js . I predefined the urlRoot and url functions . I encoded php to just return me a message (using echo ).

But no matter what I do, whenever I try to get an answer, it always refers to the error return message . I get a responseText response , but I still can not understand why the error callback is triggered. Here is my full html and internal php code. Why does an error callback always occur? I would also like to indicate that I am getting the header

HTTP/1.1 200 OK
