Answer 1

假设$ this-> cart是您的数据库，您没有错过数据库名称吗？

 $this->cart->insert('db_name', $data);

Answer 2

insert() and update() function in the cart model should be like this

public function insert($data){
    return $this->db->insert('table', $data);
}

public function update($data){
    $this->db->where('column', $value);
    $this->db->set($data);
    return $this->db->update('table');
}

Answer 3

I own find the answer , the errorr occurred because the name contains illegal characters from the URL , so I use urldecode function for name

Problem solved.
