php - jQuery, ajax multiple checkboxes into $_POST array -


i'm trying send $_post data page add sessions simple shopping cart.

i have multiple forms within php while loop each multiple checkboxes, works apart checkboxes.

my question how change piece of code change "item_extras" array?

if(this.checked) item_extras = $(this).val();

i have tried following but, creates 1 line values instead of row within array. if confusing create sample if helps.

if(this.checked) item_extras += $(this).val();

$('form[id^="add_item_form"]').on('submit', function(){     //alert("on click works");     event.preventdefault();     additem($(this)); });  function additem(ele) {     //alert("i'm in additem function");     var item_id = ele.parent().parent().find("input[name=item_id]").val(); // item id     var item_name = ele.parent().parent().find("input[name=item_name]").val(); // item name     var item_options = ele.parent().parent().find('#options').val(); // selected option     var item_extras = "";      $item_extras = ele.parent().parent().find('input[name^="extra"]'); // find extras      $item_extras.each(function() {         if(this.checked) item_extras = $(this).val(); // how make array???     });      alert("before ajax");      var datastring = 'item_id=' + item_id + '&item_name=' + item_name + '&item_options=' + item_options + '&item_extras[]=' + item_extras;      alert(datastring);      $.ajax({         type: "post",         cache: false,         url: "includes/cart.php",         data: datastring,         success: function () {             $.ajax({                 url: 'includes/cart.php',                 success: function(data) {                 $('#cart').html(data);                 alert("ajax success");                 }             });         }     });      return false; }

you can use serialize method. form.serialize()

$( "form" ).on( "submit", function( event ) {   event.preventdefault();    var data = $(this).serialize(); });
