Here is the problem I have a session
session('products')
this is actually an array that contains id
session('products')
array:4 [▼
0 => "1"
1 => "2"
2 => "4"
3 => "1"
]
Now I want to delete lets say 4 How do I do that? I tried method
session()->pull($product, 'products');
But it didn't work!
Other solution
session()->forget('products', $product);
it also didn't work
You AFAIR have to firstly retrieve whole array, edit it and then set it again. If you want to delete by product ID, which is as I assume an array value, you can use this: PHP array delete by value (not key)
$products = session()->pull('products', []); // Second argument is a default value
if(($key = array_search($idToDelete, $products)) !== false) {
unset($products[$key]);
}
session()->put('products', $products);
Session::pull takes first parameter as the item do delete and second as the default value to return. You have mistaken the order of arguments. Try:
session()->pull('products'); // You can specify second argument if you need default value
As I can see in source, Session::forget expects string or array, so you should specify only the first parameter:
session()->forget('products');
This method isn't tested:
Session::forget('products.' . $i);
note the dot notation here, its worth the try. If that isnt working, you can always do this:
$products = Session::get('products'); // Get the array
unset($product[$index]); // Unset the index you want
Session::set('products', $products); // Set the array again
You can do it in the following way in case you have a function to delete an item from a cart
public function deleteProductoCart(Producto $producto) {
$cart = \Session::get('products');
unset($cart[$producto->id]);
\Session::put('products', $cart);
return redirect()->route('tu-ruta');
}
