Solution

If I am not wrong, what I get from your question is that you want to insert multiple data in single query.

You have to give field name using array other wise it is difficult to differentiate multiple data using same key name. Array will differentiate your data using index value with same name.

Here is a simple example what you want to implement. According to this you can create your own format. Here I used table structure, if you want you can use div structure.

In Blade file:-

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" />  
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
</head>
<body>
   
<div class="container"> 
   
    <form action="{{route('invetory.create')}}" method="POST">
   
        <table class="table table-bordered" id="dynamicTable">  
            <tr>
                <th>item</th>
                <th>tax</th>
                <th>price</th>
                <th>selling_price</th>
                <th>total_price</th>
                <th>Action</th>
            </tr>
            <tr>  
                <td><input type="text" name="invetory[0][item]"  class="form-control" /></td>  
                <td><input type="text" name="invetory[0][tax]"  class="form-control" /></td>  
                <td><input type="text" name="invetory[0][price]"  class="form-control" /></td>
                 <td><input type="text" name="invetory[0][selling_price]"  class="form-control" /></td>
                  <td><input type="text" name="invetory[0][total_price]"  class="form-control" /></td>

            </tr>  
        </table> 
       <button type="button" name="add" id="add" class="btn btn-success">Add More</button>
    
        <button type="submit" class="btn btn-success">Save</button>
    </form>
</div>
   
<script type="text/javascript">
   
    var i = 0;
       
    $("#add").click(function(){
   
        ++i;
   
        $("#dynamicTable").append('<tr><td><input type="text" name="invetory['+i+'][item]"  class="form-control" /></td><td><input type="text" name="invetory['+i+'][tax]"  class="form-control" /></td><td><input type="text" name="invetory['+i+'][price]" class="form-control" /></td><td><input type="text" name="invetory['+i+'][selling_price]" class="form-control" /></td><td><input type="text" name="invetory['+i+'][total_price]" class="form-control" /></td><td><button type="button" class="btn btn-danger remove-tr">Remove</button></td></tr>');
    });
   
    $(document).on('click', '.remove-tr', function(){  
         $(this).parents('tr').remove();
    });  
   
</script>
  
</body>
</html>

And in controller you have to do like this

public function create(Request $request){
    foreach ($request->invetory as $key => $value) {
        Inventory::create($value);
    }
    return redirect()->action([InventoryController::class, 'index']);
}
