Good day, tell me, I want to get a list of customers in the product card, and until it works out, the page immediately drops to 500, what is my mistake

$this->load->model('customer/customer'); $dataCust['customer'] = $this->model_customer_customer->getCustomer($this->request->get['customer_id']); if (isset($this->model_customer_customer->post($this->request->get['customer_id']))) { $dataCust['customer_id'] = $this->model_customer_customer->post($this->request->get['customer_id']); } elseif (!empty($customer_info)) { $dataCust['customer_id'] = $customer_info['customer_id']; } else { $dataCust['customer_id'] = 0; } if (isset($this->model_customer_customer->post($this->request->get['customer_id'])) { $dataCust['customer'] = $this->model_customer_customer->post($this->request->get['customer_id']); } elseif (!empty($customer_info)) { $customer_info = $this->model_customer_customer->getCustomers($customer_info['customer_id']); if ($customer_info) { $dataCust['customer'] = $customer_info['name']; } else { $dataCust['customer'] = ''; } } else { $dataCust['customer'] = ''; }
