to array , must convert name accept multiple change input's :
name="cim" to
name="cim[]" also jquery ajax function should :
<script type="text/javascript"> $(function(){ $("form").on("submit",function(e){ e.preventdefault(); var checkedvalue = $(this).serialize(); $.ajax({ type: "post", url: "proba.php", data: checkedvalue, success: function(){ alert("ok"); } });//end ajax });//end form submit }); </script> in php cim array example
var_dump($_post["cim"]); hope helps
