Send array through Ajax

Question

I want to send an array to PHP through Ajax.

array = $('.def-mask :checkbox:checked').serialize();
$.ajax({
    url: 'ajax/battle.php',
    type: 'post',
    data: { playerReady: 1, attack: attack, defence: array },
    success: function(data) {
        alert(data);
    }
});

But when I do var_dump($_POST['defence']), I get string(), and not array(). Why do I get a string, and not an array?

Have you maybe forgotten to append [] to the name of your checkboxes? I don't know if jQuery deals with that automatically, I think it does... — Kiruse

Do console.log(decodeURIComponent($.param({ playerReady: 1, attack: attack, defence: array })); and see how your data gets actually formatted. — Felix Kling

@pbibergal: The data is sent in the body of the request, not the header, and of course every request only contains of character data. But json_decode wouldn't help because the data is not formatted as JSON. — Felix Kling
