Question

I am trying to pass a jquery string to my cakephp controller but I keep getting an error saying json_decode expects a string but is passed an array.

Here is the code for my ajax:

var str = 'Data that i need';

    var jsonString = JSON.stringify(str);

    $.ajax({
        type: "POST",
        url: "http:/Configs/",
        cache: false,
        datatype: 'json',
        data: {data : jsonString},
        timeout: 100000,

        success: function(data) 
        {
            alert('Ok');
        }
    });

and in my controller im trying to recieve the data like so:

$value = json_decode($_POST['data']);

but im getting the error stated above any idea how to solve this would be great thanks.

Answer 1

Are you sure the url you use is correct?
If you are using CakePHP, then why don’t you work with $this->request->data?

Try to debug your code with

pr($_POST); exit;

or

pr($this->request); exit;

What do they say?
