AJAX showing retrieved values as undefined

Question

I am using AJAX to send values to PHP and retrieve the values from PHP. The problem is the value i am getting from PHP is viewed as undefined in AJAX. Please help me solve this

Answer 1

Because you are encoding your data in json.

Try adding dataType:"json" in your ajax and ajax has type not method so change to type data should be in {} only:

$.ajax({
   type:"GET",
   url:"dash2.php",
   dataType: 'json',
   data:{channel:channel},
   success:function(data){
      console.log(data.a);
      console.log(data.b);
      console.log(data.c);
   }
 });

Try putting this line:

$channel=$_GET['channel'];

after db selection:

mysql_select_db($dbname);
