You should create functions in a controller like insert, update, delete, and clear cart etc. eg : for insert new item in cart write below code that accepts value. $cartItem = array( 'id' => 'MOTOG5', 'qty' => 5, 'price' => 100.99, 'name' => 'Motorola Moto G5 - 16 GB',...

$data = array( array( 'id' => 'sku_123ABC', 'qty' => 1, 'price' => 39.95, 'name' => 'T-Shirt', 'options' => array('Size' => 'L', 'Color' => 'Red') ), array( 'id' =>...

This example is based on this post: TensorFlow - numpy-like tensor indexing. In Numpy you can use arrays to index into an array. E.g. in order to select the elements at (1, 2) and (3, 2) in a 2-dimensional array, you can do this: # data is [[0, 1, 2, 3, 4, 5], # [6, 7, 8, 9, 10, 11], # ...
