laravel select search

@Sinnbeck Which i select in create.blade.php

my need html code

@ArsenMK you select in the controller and pass it to the view (blade file)

In blade you can do

{{$x->length}} 

@Sinnbeck I'm going to try now

@ArsenMK otherwise show your controller method and blade file:)

@Sinnbeck create.blade.php

     <form  action="{{ route('productions.store') }}" method="POST">
                    @csrf
         <div>
       <div class="col" style="margin-top: 36px;">
                <select  name="" style="width: 170px" class="form-control" >
                        <optgroup   label="width">
                     @foreach($products as $product)
                         <option value="{{$products->width}}"> {{$products->width}}  </option>
                     @endforeach

                        </optgroup>
                </select>
       </div>

             <div class="col-xs-12 col-sm-12 col-md-12 text-center">
                 <button type="submit" class="btn btn-primary">Submit</button>
             </div> 
         </div>
                </form>

ProductionController@create

  public function create()
    {
        $products = Product::all();
        $length = $products->length;
        $width= $products->width;
 return view('productions.create',compact('products'));
    }

ProductionController@store

  public function store(Request $request)
    {
        Product::create([
            'length' => $request['length'],
            'width' => $request['width'],
            'area'=> $request['width']*$request['length']
        ]);

@ArsenMK you get every single product

$products = Product::all();
return view('productions.create',compact('products'));

But your blade file just passes 1 width? Should the user choose width and length separately or together?

Did you mean to do this?

<select  name="product_id" style="width: 170px" class="form-control" >
foreach($products as $product)
                         <option value="{{$product->id}}"> {{$product->width}}  -  {{$product->length}}   </option>
                     @endforeach

And in store()

$product = Product::find($request->input('product_id' );
Product::create([
            'length' => $product->length,
            'width' => $product->width, 
            'area'=> $product->length * $product->width
        ]); 

Be aware that no one except you know what you are trying to build, so we can only guess your logic

@Sinnbeck I want to select id and when I select id I want automatic width and length to come

@Sinnbeck I need that when I select an id and click on submit, the width and length of THIS id are saved in the database in one table

which of these can you tell me how to do

@ArsenMK I think I already did in my example?

@Sinnbeck I haven't tried it yet, when I try I'll tell you right away

Trying to get property 'length' of non-object

@ArsenMK can you show exactly what you have? Be aware that I changed your code a bit? And where do you get the error? When storing?

If you do then try

$product = Product::findOrFail($request->input('product_id'); 

@Sinnbeck 404 NOT FOUND

@Sinnbeck error is here

    1 public function store(Request $request)
    2 {
    3   $product = Product::find($request->input('product_id' ));
    4  Product::create([
    5      'length' => $product->length,
    6      'width' => $product->width,
    7      'area'=> $product->length * $product->width
    8
    9   ]);

error is in 5 line

@Sinnbeck so this error does not go away

@Sinnbeck thank you so much for your help i got it
