在Laravel中迭代抛出复选框列表（即使未选中）

Question

I have a table of items, and if the user selects an item I need to know how many units are assigned to this item. So I created a check box list coming back with the selected items ids and another one for units.

<td>{{$item->name}}</td>
<td>{{Form::checkbox('itemchks[]', $item->id)}}</td>
<td>{{Form::text('units[]','0')}}</td>

The problem is that, unless the user checks all items we get 2 different-size lists. For ex, when choosing 3 items, and assigning them some units values, the itemchks come back with these ids

["4","15","23"]

but the units list returns

["15","0","18","0","0","0","0","0","20"]

so I can't know, exactly, each id and its correspondent units.

I'm using laravel 4.2

Any ideas will be appreciated.

Instead of letting the browser set the key in your units[] array you could do that yourself using the $item->id :

<td>{{$item->name}}</td>
<td>{{Form::checkbox('itemchks[]', $item->id)}}</td>
<td>{{Form::text('units['.$item->id.']','0')}}</td>
