Can you help me determine the best way to extract data from a php page using ajax in the form of a json array? Here is an example code snippet:
$.ajax({
type: "get",
url: "assets/update_cart_user_fstore.php",
data: up,
cache: false,
success: function(r){
$(#item).html(r);
},
});
In the PHP page, I am echoing a variable like this:
$hello = "I am code!";
echo $hello;
Now, with JSON involved:
$.ajax({
type: "get",
url: "assets/update_cart_user_fstore.php",
data: up,
cache: false,
success: function(r){
var obj = jQuery.parseJSON(r);
$('#item').html(obj.code);
},
});
And in the PHP script, I'm echoing the JSON array like so:
$hello = "I am code!";
$response = array();
$response['code'] = $hello;
echo json_encode($response);
I understand that using JSON is advisable when dealing with more than one variable being echoed. But in this particular scenario, is it necessary or appropriate to use JSON? Can you provide some explanation on this matter?
Your insights are greatly appreciated.
