    <div class="row justify-content-center">
        <div class="col-md-12">
            <div class="card">
                <div class="card-header">PURCHASE FORM</div>

                <div class="card-body">
            
                @if (Session::has('success'))
                    <div class="alert alert-success">{!! Session::get('success') !!}</div>
                @endif
                @if (Session::has('failure'))
                    <div class="alert alert-danger">{!! Session::get('failure') !!}</div>
                @endif
                         
    <form method="POST"   action="" enctype="multipart/form-data">
 @csrf
<div class="form-row">

    <div class="col-md-4 mb-3">
      <label >product NAME</label>
      <input type="text"  name="product[]"  placeholder="product" value="" required >
    </div>
    <div class="col-md-4 mb-3">
      <label >quantity</label>
      <input type="text"  name="quantity[]"  placeholder="quantity" value="" required >
    </div>
    <div class="col-md-4 mb-3">
      <label >price</label>
      <input type="text"  name="price[]"  placeholder=price" value="" required >
    </div>
    <div class="col-md-4 mb-3">
      <label >manufacturer</label>
      <input type="text"  name="manufacturer[]"  placeholder="manufacturer" value="" required >
    </div>
  </div>
</div>
<button class="btn btn-primary float-right" type="submit">SAVE</button>
</form>

this is route part

Route::post('purchasesave', 'PurchaseController@purchasesave')->name('purchasesave');

This is my controller (PurchaseController.php) and I have 3 model (Purchase , Bill_product and Item_list )

 public function purchasesave(Request $request)
   {
     //insert your validation here
    
     foreach($request->product as $k => $p){
       Pruchases::create([
           'product' => $request['product'][$k],
           'quantity' => $request['quantity'][$k],
           'price' => $request['price'][$k],
           'manufacturer' => $request['manufacturer'][$k],
       ]);

       BillProduct::create([
           'product' => $request['product'][$k],
           'quantity' => $request['quantity'][$k],
           'price' => $request['price'][$k],
       ]);
 
       ItemList::create([
           'product' => $request['product'][$k],
           'quantity' => $request['quantity'][$k],
       ]);
     }
   }
