CodePudding user response：

You don't pass the product to the view. You need to compact the variable like this in the controller:

public function show($id)
{
    $product = Product::findOrFail($id);
    return view('shop.show', compact('product'));
}

CodePudding user response：

you are getting product from database in $product variable, but not passing that variable to your view. There are several ways to pass variables to view.

return view('shop.show', compact('product'));

return view('shop.show', ['product' => $product]);

return view('shop.show', get_defined_vars());

get_defined_vars() is built-in php function, by using this function any numbers of variables declared in method, all will be passed to view
