how to handle dynamically created forms laravel 5.4 - laravel

Question

I want to know how to fetch name of checkboxes from dynamically created form. First I am displaying each records of data in a separate form then If records need to be deleted we will be able to delete. I am able to give different name as somename+id. But how do I know which name is going in the controller. As It is not clear that which name is going in the controller, I am not able to delete the record. I am doing it in laravel 5.4. Here is my code -
#if (isset($allcolors))
#foreach ($allcolors as $color)
<tr>
<form method="post" action="/delete">
{{csrf_field()}}
<input type="hidden" name="_method" value="DELETE">
<td>
<span class=""><input type="checkbox" name="deletecolor[{{$color->id}}]" value="{{$color->id}}"></span>
</td>
<td>
<div style="background:{{$color->web_color}}">a</div>
</td>
<td>{{$color->color_name}}</td>
<td>
<button type="submit" class="btn btn-danger">
Delete
</button>
</td>
</form>
</tr>
#endforeach
#endif
then on form submission I want to fetch which I am doing like this -
public function destroy(Request $request)
{
//
$id = $request->input('deletecolor');
$affected = DB::update("DELETE FROM vehicle_color where id = ?", [$id]);
//echo $affected==1?"Successfully Deleted":"Delete Fail";
}

I see you have $color->id. Why not delete them based on that?
#if (isset($allcolors))
#foreach ($allcolors as $color)
<tr>
<form method="post" action="/delete">
{{csrf_field()}}
<input type="hidden" name="_method" value="DELETE">
<td><span class=""><input type="checkbox" name="deletecolor[{{ $color->id }}]" value="{{$color->id}}"></span></td>
<td><div style="background:{{$color->web_color}}">a</div></td>
<td>{{$color->color_name}}</td>
<td><button type="submit" class="btn btn-danger" data-toggle="modal" data-target="#colorDelPopup">Delete</button></td>
</form>
</tr>
#endforeach
#endif
And in your controller:
public function destroy(Request $request)
{
$ids = $request->input('deletecolor');
// Instead of raw SQL, you can use the query builder to make your life a bit easier
$affected = DB::table('vehicle_color')->whereIn('id', $ids)->delete();
//echo $affected==1?"Successfully Deleted":"Delete Fail";
}
This should do the trick.
