404 on add to cart laravel - laravel

Question

i have this situation on add to cart when i want to add to cart i am getting 404 error,
this is my route
Route::get('/add-to-cart/{product}', [CartController::class, 'addToCart'])->name('add.cart');
Route::get('/remove/{id}', [CartController::class, 'removeFromCart'])->name('remove.cart');
Route::get('/change-qty/{product}', [CartController::class, 'changeQty'])->name('change_qty');
This is controller
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Products;
class CartController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
//
return view('cart.index');
}
public function addToCart(Products $product)
{
$cart = session()->get('cart');
if (!$cart) {
$cart = [$product->id => $this->sessionData($product)];
return $this->setSessionAndReturnResponse($cart);
}
if (isset($cart[$product->id])) {
$cart[$product->id]['quantity']++;
return $this->setSessionAndReturnResponse($cart);
}
$cart[$product->id] = $this->sessionData($product);
return $this->setSessionAndReturnResponse($cart);
}
public function changeQty(Request $request, Products $product)
{
$cart = session()->get('cart');
if ($request->change_to === 'down') {
if (isset($cart[$product->id])) {
if ($cart[$product->id]['quantity'] > 1) {
$cart[$product->id]['quantity']--;
return $this->setSessionAndReturnResponse($cart);
} else {
return $this->removeFromCart($product->id);
}
}
} else {
if (isset($cart[$product->id])) {
$cart[$product->id]['quantity']++;
return $this->setSessionAndReturnResponse($cart);
}
}
return back();
}
public function removeFromCart($id)
{
$cart = session()->get('cart');
if (isset($cart[$id])) {
unset($cart[$id]);
session()->put('cart', $cart);
}
return redirect()->back()->with('success', "Removed from Cart");
}
protected function sessionData(Products $product)
{
return [
'name' => $product->nume,
'quantity' => 1,
'price' => $product->pret,
];
}
protected function setSessionAndReturnResponse($cart)
{
session()->put('cart', $cart);
return redirect()->route('cart')->with('success', "Added to Cart");
}
This is what i have in view file:
<a class="theme_btn add_cart w-100" href="{{route('add.cart', [$produs->id])}}">add to cart
<span class="theme_btn_eff"></span>
</a>
In my loop when i fetch products, on click is redirecting me to 404 page without getting an error, i was trying to get dd($product) into controller but i get again 404.

Answer 1

Change this line
<a class="theme_btn add_cart w-100"
href="{{ route('add.cart', [$produs->id]) }}" >add to cart
<span class="theme_btn_eff"></span>
</a>
To This
<a class="theme_btn add_cart w-100"
href="{{ route('add.cart', ['product' => $produs->id]) }}" >add to cart
<span class="theme_btn_eff"></span>
</a>
In routes file you have passed route parameter naming {product} in url /add-to-cart/{product}, hence you need to mention it in view file as well {{ route('add.cart', ['product' => $produs->id]) }} thats the naming convention laravel follows
Route::get('/add-to-cart/{product}', [CartController::class, 'addToCart'])->name('add.cart');
