error post data key , data value, how fix it?

you use json.stringify(datastring) encode array in javascript, , use $array=json_decode($_post['string']); in php script retrieve it.

function load_edit_row(input) {    var id = $(input).parent().attr('data-id');    var datastring = [];     $("tr[data-id="+id+"] :input").each(function(e){        datastring.push(this.value);    }); var string = json.stringify(datastring);    $.ajax({       type: 'post',       url: 'update-row.php',       data: 'string='+string,       success: function(itemjson) {        }    }); }
