php json_encode not returning proper json encoded string

Question

I am using a jquery ajax call which accepts json response :

 var posturl = \'/admin/getparamdetails/\';
    var data = \"adnetworkId=\"+adnetworkId;
    $.a         


        

Answer 1

you have to send the data as Content-Type "application/json", otherwise it won't work.

Just add the following in your PHP File:

header('Content-type: application/json');

Answer 2

Use parseJSON on the return data:

if (msg) {
  msg = $.parseJSON(msg);
  alert(msg.hello);
}
