How to remove an item from session array in laravel

Question

Here is the problem I have a session

session(\'products\')

this is actually an array that contains id

session(\'products\')         


        

Answer 1

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);

Misunderstood question

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');

Answer 2

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
