I am unable to save an array of items from session to mysql database with an error:
"Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_ERROR) Call to a member function save() on string"
When I do a dd(Dump and Die) the array is displayed as below:
"{"1":{"name":"Bajiya","quantity":4,"price":"34.00"},
"2":{"name":"Gulha","quantity":2,"price":"3.00"},
"3":{"name":"kavaabu","quantity":1,"price":"2.00"}}"
Below is the controller store function:
public function storeCart(Request $request){
$cart = new Cart;
$cart= session()->get('cart');
$cart = json_encode($cart);
$cart->save();
}
I have a table in my Database with columns for id and cart. I want the array above to be saved in the cart column.
Thanks
Each time you override previous variable $cart
$cart = new Cart; //put into $cart instance of Cart class
$cart = session()->get('cart'); // overwrite other data to variable $cart
$cart = json_encode($cart); // json_encode converts object/array to json (so at this moment you overwrite string to variable `$cart`
$cart->save(); //you're trying to call function on json)))
Please try to understand, what exactly you want to do))
Works with the function below.
public function storeCart(Request $request){
$cart = new Cart();
$cart->cart = $request->session()->get('cart');
$cart->save();
$request->session()->forget('cart');
return redirect()->route('/');
}
To put my explanation in a simple term, you need to point to the columns in the DB where the records will be persisted. The code could look like this below
$cart = new Cart;
$cart->name= session()->get('name');
$cart->quantity = session()->get('quantity');
$cart->price = session()->get('price');
$cart->save();
Since you are saving an array of items you may want to use the foreach and the code will change to something like this:
foreach ($cart as $item){
$item->name= session()->get('name');
$item->quantity = session()->get('quantity');
$item->price = session()->get('price');
$item->save();
}
You may also want to consider using relationships. Hope this makes sense and helps.
