Question

Good day stackoverflow‘ers

I’m doing a simple AJAX form, imagine some kind of registration.

This form posts the value to a PHP file which posts this to a database and returns a string like this one “success id:12345“. I want this script to read JSON and check ID, success and so, the current code is:

// Some pieces of code 
        success: function(data){
            var reponse = $.trim(data);
            if (reponse.toLowerCase().indexOf("yes") >= 0){
                // check the id (Don't know how)
                alert("Your id is "+id);
            }else{
                alert(reponse);
            }
        }

Thanks!

PHP:

$response = array(
  "success" => true, 
  "id"      => 1234
);

Then json_encode($response);

The browser will get this…

{
  "success" : true,
  "id"      : 1234
}

You can make the ajax request and jQuery will parse the JSON for you.

$.getJSON("path/to/something.php", {var1: 1, var2: 2}, function(json){
  if(json.success){
    alert("Your id is " + json.id);
  }
});
