I declare my array:
p.myArray = [];
I add to the array in a loop:
self.myArray.push($(this).data('id')); // [1,2,3,4]
I then send this via AJAX to PHP via POST:
$.ajax({
url: '/gateway',
data: {data: self.myArray},
dataType: 'json',
type: 'POST',
})
I was wondering, do I need to have a key/value pair? Can I just send through the array? Does it need serialising?
Passing an object to data
will cause jQuery to serialise it for you.
The array will be available in $_POST['data'][]
It would be clearer if you didn't use the same name for different things.
data: { theArray: self.myArray },
goes to:
$_POST['theArray'][]
Note that if you are using dataType: 'json'
your PHP script will have to return JSON serialised data or jQuery will ignore the response.
ie:
$myArray = $_POST['myArray'];
echo json_encode($myArray);
