I've been trying to direct the add to cart button on the home page of the website(for online shopping) to the addtocart file and the shopping cart. I just can't seem to find what's wrong. Here are the codes.

addtocart.blade.php
<?php

$product_id = $_POST['product_id'];
// Initialize the cart if it doesn't exist
if (!isset($_SESSION['cart'])) {
$_SESSION['cart'] = [];
}
// Add product to cart
if (isset($_SESSION['cart'][$product_id])) {
$_SESSION['cart'][$product_id]++;
} else {
$_SESSION['cart'][$product_id] = 1;
}
// Redirect to shopping cart page
header('Location: shoppingcart.php');
exit;
}
?>
web.php
Route::get('/home',[HomeController::class, 'home'])->name('home');
Route::get('/shoppingcart', [CartController::class, 'showcart'])->name('shoppingcart');
Route::post('/addtocart', [CartController::class, 'addtocart'])->name('addtocart');
CartController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class CartController extends Controller
{
public function addtocart(Request $request)
{
$product_id = $request->input('product_id');
$cart = session()->get('cart', []);
if(isset($cart[$product_id])) {
$cart[$product_id]++;
} else {
$cart[$product_id] = 1;
}
session(['cart' => $cart]);
return redirect()->route('shoppingcart');
}
public function showcart()
{
$cart = session('cart', []);
return view('shoppingcart', compact('cart'));
}
}
Supposedly, when a user clicks the add to cart button on the home page, it redirects to the shopping cart page.
addtocart.php, which doesn't exist. Your actual route is/add-to-cart, as created in yourweb.phproutes. You should have absolutely no cart logic in your blade files, it should be in the controller..blade.phpfiles, but there are replacements.<?php if (...) { ?> ... <?php } ?>can be written as@if(...) @endif.<?php foreach(...) { ?> <?php } ?>is@foreach(...) @endforeach, etc. Follow some tutorials, read some documentation, and you'll get the hang of it 🙂
