php - Updating Database in Laravel 4 with AJAX Data -

i see there many similar questions out there 1 none have them have given me looking for.

i have jquery sortable list of records. when user moves record or down (so re-order records), jquery's .ajax() function should take data , pass laravel controller function called second(). function second() should take data and, each row, extract position (represented integer) , update 'order' column in database table. records should display in order on view.

i have working point data passed second() function:

route:

route::post( '/income-category/second', array(   'as' => 'income-category.second',   'uses' => 'incomecategorycontroller@second' ));  

jquery:

$("#sortable").sortable({     update : function () {         var serial = $('#sortable').sortable('serialize'); //split each li array item         $("body").css("cursor", "progress");         $.ajax({             url: base_url + "income-category/second",             type: "post",             data: {serial: serial},             cache: false,             datatype: 'json',             success: function(info){               console.log(info);             },             error: function(){                 alert("there's error ajax");             }         });     } }); 

controller (incomplete):

public function second(){        $orders = input::all();      foreach($orders $order){         $folge[] = $order;       }      return response::json($folge); } 

after troubleshooting, got ajax output pop on console. turns out foreach loop represented above throw "invalid foreach argument" error because - i'm assuming - there 1 key in following object:

object {serial: "item[]=2&item[]=3&item[]=1&item[]=4&item[]=5"}  

when have done in other, non-laravel projects, simple foreach($_post['item'] $item) worked. not.

html excerpt:

<tbody id="sortable">       @if(isset($_get['category']))           {{ form::open(array('route'=> array('income-category.update', $_get['category']), 'method'=>'put')) }}           @foreach($categories $catid=>$catval)             @if($_get['category'] == $catid)               <tr id="{{ 'item_'. $_get['category'] }}">                 <td>{{ form::text('category_name', $catval) }} <br>{{ $errors->first('category_name') }}</td>                 <td>                   {{ form::submit('save', ['category'=>$catid, 'class'=>'btn btn-success btn-sm', 'name' => 'submit_' . $_get['category'], 'title'=>'save']) }}&nbsp;                   {{ link_to('income-category', 'cancel', ['class'=>'btn btn-default btn-sm', 'title'=>'cancel']) }}                 </td>               </tr>             @else               <tr>                   <td>{{ $catval }}</td>                 <td>{{ html::linkaction('incomecategorycontroller@index', '', ['category'=>$catid], ['class'=>'glyphicon glyphicon-pencil shadow pointer', 'title'=>'edit']) }}&nbsp;&nbsp; {{ form::button('', ['category'=>$catid, 'type'=>'submit', 'class'=>'glyphicon glyphicon-trash shadow pointer', 'name' => 'delete' . $_get['category'], 'title'=>'delete', 'onclick' => 'confirm("for going delete no matter pick.")']) }} </td>               </tr>             @endif         @endforeach         {{ form::close() }}         ...         ... 

i confused beyond hope makes little sense.
