The Controller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\ProductStock;
class ProductAddMoreController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function addMore()
{
return view("addMore");
}
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function addMorePost(Request $request)
{
$request->validate([
'addmore.*.name' => 'required',
'addmore.*.qty' => 'required',
'addmore.*.price' => 'required',
]);
foreach ($request->addmore as $key => $value) {
ProductStock::create($value);
}
return back()->with('success', 'Record Created Successfully.');
}
}
You can flash the request inputs into the session during the post request if it fails and then check in the other route if the data you flashed is there and then some logic to build the table based on old inputs https://laravel.com/docs/8.x/requests#flashing-input-to-the-session
Or if your lazy you could make an XHR request upon submitting the form just for validation checks, and then only submit it if it passed
