laravel 5.3 - multiple rows insert to database table - php

Question

I am trying to add multiple subitems to my eloquent model as arrays but am unable to do so.
View:
<div class="row">
<div class="col-md-6">
<form class="" action="{{route('production.update', $rm->id)}}" method="post">
<input name="_method" type="hidden" value="PATCH">
{{csrf_field()}}
<!-- <input type="hidden" name="product_id" id="product_id" class="form-control" value="{{$rm->id}}"> -->
<div class="form-group{{ ($errors->has('batch_id')) ? $errors->first('title') : '' }}">
<lable>Batch ID</lable>
<input type="text" name="batch_id" id="batch_id" class="form-control" value="{{$rm->product_id}}" readonly="">
{!! $errors->first('wastage','<p class="help-block">:message</p>') !!}
</div>
<div class="form-group{{ ($errors->has('item_id')) ? $errors->first('title') : '' }}">
<lable>Item Name</lable>
<input type="hidden" name="item_id" id="item_id" class="form-control" value="{{$rm->item_id}}" readonly="">
<input type="text" class="form-control" value="{{$rm->item->item_name}}" readonly="">
{!! $errors->first('wastage','<p class="help-block">:message</p>') !!}
</div>
<div class="form-group{{ ($errors->has('rquantity')) ? $errors->first('title') : '' }}">
<lable>Quantity (Kg)</lable>
<input type="text" name="rquantity" id="rquantity" class="form-control" value="{{$rm->quantity}}" readonly="">
{!! $errors->first('wastage','<p class="help-block">:message</p>') !!}
</div>
<div class="form-group{{ ($errors->has('')) ? $errors->first('title') : '' }}">
<lable>Packing</lable>
#foreach($subitem as $sub)
<div class="row">
<div class="col-md-4">
<input type="checkbox" name="subitem[{{$sub->id}}]['subitem_id']" value="{{$sub->id}}"> {{$sub->subitem_name}}<br><br>
</div>
<div class="col-md-4">
<input type="text" name="subitem[{{$sub->id}}]['qty']" id="qty" class="form-control" placeholder="Entire Qty">
{!! $errors->first('qty','<p class="help-block">:message</p>') !!}
</div>
</div>
#endforeach
</div>
<div class="form-group">
<input type="submit" class="btn btn-primary" value="Add">
</div>
</form>
</div>
</div>
Controller:
public function update(Request $request, $id)
{
$result = Production::findOrFail($id);
foreach($request->subitem as $key=>$row)
{
//print_r($request->subitem);exit;
$items = new Itempacking;
$items->batch_id = $result->product_id;
$items->item_id = $result->item_id;
$items->rquantity = $result->quantity;
$items->product_id = $result->id;
$items->subitem_id = $row['subitem_id'];
$items->qty = $row['qty'];
$items->status = 1;
$items->save();
$items='';
}
}
When I uncomment this line print_r($request->subitem); exit; I can see like this:
Array (
[3] => Array (
['subitem_id'] => 3
['qty'] => 2
)
[4] => Array (
['subitem_id'] => 4
['qty'] => 3
)
)
But when I comment and try to send data to table it is not working. It gives this message
Undefined index: subitem_id

Don't insert '' for key of array in HTML code.You can print your request to details.
Replace from
subitem[{{$sub->id}}]['subitem_id']
subitem[{{$sub->id}}]['qty']
to
subitem[{{$sub->id}}][subitem_id]
subitem[{{$sub->id}}][qty]
