Send nested array via jQuery .ajax

Question

I have an array of which each element is an array, like so:

results = {
              {1, "A", 11, 0, 7, 0},
              {2, "A", 13, 2, 2, 1},
              {3, "A",  7, 0, 2, 2}
          }

And I was wondering how I could send this to PHP via jQuery's .ajax function?

My jQuery call at the moment looks like:

$.ajax({type: "POST",
        url:  "updateResults.php",
        data: "results="+results,
        success: function(data) {
            if(data == "ok") {
                $("#msgSuccess").show();
            } else {
                $("#msgError").show();
            }
        }
});

Thanks!

This is not correct JavaScript. Maybe you meant [] instead of {}? It depends on in which format you want to send the data. The simplest would be data: {results: results}, or you serialize it as JSON. — Felix Kling

This is a duplicate of stackoverflow.com/questions/191881/… It basically tells to use the stringify method as shown below, in fact recommended by John Resig. var json_text = JSON.stringify(your_object, null, 2); — Sunil Bannur

@FelixKling - Yeah, sorry, stupid error while posting the question - it uses [] in my code! — Chris Matthews

The easiest is to use an object for data:

data: {results: data};

jQuery will automatically URI-encode the data if you do so, which is more advantageous than messing around with string concatenation yourself.

If the results is in string format then this works Fiddle

var results = '{{1, "A", 11, 0, 7, 0}, {2, "A", 13, 2, 2, 1}, {3, "A",  7, 0, 2, 2}}';
results = results.replace(/{/gi, '[');
results = results.replace(/}/gi, ']');
results = eval(results); //This is your array format which can be sent as JSON request data

$.each(results, function(index, item){
    $.each(item, function(ind, it){
        alert(it);
    });
});
