I have been having trouble storing an array in session. I am making a shopping cart and it doesn't seem to work.
public function __construct(){
$product = array(1,2,3,4);
Session::push('cart', $product);
}
and then retrieve it in the view like this.
{{Session::get('cart')}}
However I keep getting an error like this.
htmlentities() expects parameter 1 to be string, array given
Any clues and advice on how to create a shopping cart that stores an array of items.
If you need to use the array from session as a string, you need to use Collection like this:
$product = collect([1,2,3,4]);
Session::push('cart', $product);
This will make it work when you will be using {{Session::get('cart');}} in your htmls. Be aware of Session::push because it will append always the new products in sessions. You should be using Session::put to be sure the products will be always updating.
You're storing an array in the session, and since {{ }} expects a string, you can't use {{Session::get('cart')}} to display the value.
The {{ $var }} is the same as writing echo htmlentities($var) (a very simple example).
Instead, you could do something like:
@foreach (Session::get('cart') as $product_id)
{{$product_id}}
@endforeach
echo $collection or use {{ $collection }}, the Collection handles this automatically using a __toString() method. The $request->all() would be handled as a Collection, rather than a normal array.If you use 'push', when initially creating the array in the session, then the array will look like this:
[
0 => [1,2,3,4]
]
Instead you should use 'put':
$products = [1,2,3,4];
$request->session()->put('cart', $products);
Any subsequent values should be pushed onto the session array:
$request->session()->push('cart', 5);
You can use .:
$product = array(1,2,3,4);
Session::put('cart.product',$product);
You can declare an array in session like
$cart = session('data', []);
$cart[] = $product;
session([ 'data' => $cart]);
return session('data', []);
you can also do it like that:
$data = collect($Array);
Session()->put('data', $data);
return view('pagename');
