How to insert multiple row from form in laravel 8 - php

Question

I have a table in a form similar to this:
products
comments
product 1
comment 1
product 2
comment 2
Only comment field is writable where user can enter a comment regarding each product
Products are displayed from database (not in an input element)
I want, when user click on save button, each row is added in database as it is in the form (as pairs [product i, comment i])
I tried
foreach ($request->products as $key=>$product) {
$saveData = [
'product' => $request->product[$key],
'comment' => $request->comment[$key],
];
DB::table('prod_com')->insert($saveData);
}
in controller and
<form id="regForm" method="post" >
#csrf
<table>
<tr>
<th>Product</th>
<th>Comment</th>
</tr>
#foreach($prdcts as $products)
<tr>
<td>{{$products['product']}}</td>
<td>
<input type="text" class="form-control" name="comment[]" >
</td>
</tr>
</table>
in form but either data isn't added in database or i get a 405 error Method Not Allowed..
Any help is highly appreciated !
Edit :
Full html form
<form id="regForm" action="{{route('saved')}}" method="post" >
#csrf
<table class="table table-responsive table-condebsed table-hover">
<thead>
<tr>
<th scop="col"> Product </th>
<th class="col-md-6" scop="col"> Comment </th>
</tr>
</thead>
<tbody>
#foreach($prdcts as $products)
<tr>
<td>{{ $products['product'] }}</td>
<td>
<input type="text" class="form-control" name="comment[]" >
</td>
</tr>
#endforeach
</tbody>
</table>
<br>
<button type="submit" class="btn btn-sm btn-success">save</button>
</form>
& route :
Route::post('/saved', [App\Http\Controllers\ProdComController::class, 'submitData'])->name('saved');

Answer 1

Change html code as below
#foreach($prdcts as $key=>$products)
<tr>
<td>{{$products['product']}}</td>
<td>
<input type="hidden" class="form-control" name="product[{{ $key}}][product]" value="{{$products['id']}}">
<input type="text" class="form-control" name="product[{{ $key}}][comment]" >
</td>
</tr>
#endforeach
then in controller
DB::table('prod_com')->insert($request->product);
if you get any error then try to print $request like below
dd($request->all());
so you can check data format in the request.If still issue then let me know in the comment

Answer 2

you can use for loop while saving your data into database
for ($i = 0; $i < count($request->comment); $i++) {
$comment = Commet::create([
'comment' => $request->comment[$i],
]);
}
