无法检索通过ajax发送的数组

Question

This is my function that get's all the id's ad stores them in an array them it sends the array to the php page. Using google chrome network tool i can see the request which has the array in the header.

$(document).ready(function() {
    $("#insert_articoli").click(function(){
        var id_articoli = [];
        $.each($("input[name='articoli']:checked"), function(){
            id_articoli.push($(this).val());
        });
                    $.ajax({
                     type: "POST",
                     url: "componi_prodotto.php",
                     data: {data : id_articoli },

                     success: function(){
                             alert("OK");
                     }
             });
    });
});

I can't find a way to retrieve this array from my php page. Please help.

Make sure you're echoing something in your PHP, then you need to have something to return to, so set a variable in the success function:

success: function(response){ // whatever is echoed in PHP will be in 'response'
     console.log(response);
}

Please, quit using alert() for troubleshooting., use console.log() instead.
