How can i show data from my controller in a textbox? - laravel

Question

Hi i calculated a discount in my controller by requesting in a form the percentage and the sale_price, so i did this:
public function store(Request $request){
dd($request->all());
$presupuestoProducto = new PresupuestoProducto();
$presupuestoProducto->sale_price = $request->sale_price;
$presupuestoProducto->discount_percentage = $request->discount_percentage;
$presupuestoProducto->discount = ($sale_price * $discount_percentage)/100;
$presupuestoProducto->save();
Session::flash('success');
return redirect()->route('presupuestos-productos.view');
}
But now i want to make the result of $presupuestoProducto->discount to appear in a textbox. So it would be like an autocomplete field. So up to now i have it this way in my view.
<div class="form-group col-md-2">
<label for="sale_price">Precio de Venta</label>
<input type="number" pattern="[0-9]+([\.,][0-9]+)?" step="00.01" name="sale_price" class="form-control">
</div>
<div class="form-group col-md-3">
<label for="discount_percentage">Porcentaje de descuento (%)</label>
<input type="number" name="discount_percentage" class="form-control">
</div>
<div class="form-group col-md-3">
<label for="discount">Descuento</label>
<input type="number" name="discount" class="form-control" value="discount">
</div>
As you can see my last div is an input but i want it to be a text box that automatically appears the result of $presupuestoProducto->discount as i fill in the first two inputs. How should i do this?

Answer 1

you have to use view() and pass the $presupuestoProducto with compact() then you access to the var in your view with it's name
$presupuestoProducto->save();
return view("ProductView",compact( 'presupuestoProducto'))
in view : ProductView
<div class="form-group col-md-3">
<label for="discount">Descuento</label>
<input type="number" name="discount" placeholder="discount" class="form-control" value={{$presupuestoProducto->discount}} >
</div>
but if you wanna use route you can try route parameter
