[英]codeigniter 4 set session variable $session = \Config\Services::session(); globally
[英]Codeigniter Session variable not set
我正在嘗試使用$ this-> session-> set_userdata($ booking_data)設置會話變量,但不會設置會話變量。 我的控制器是:
<?php
class Car extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->model(array('Tariff_model', 'Category_model', 'Brand_model', 'Car_model', 'Booking_model'));
$this->load->helper('formatting_helper');
}
function index($car_id = 0)
{
//price calculation
$delivery_charge = $data['locations'][$this->input->post('start_location')]['delivery_charge'];
$collection_charge = $data['locations'][$this->input->post('return_location')]['collection_charge'];
$tax_vat = config_item('vat')/100;
$booking_price = ($car->price_3*$total_days) + $delivery_charge + $collection_charge;
$booking_price_vat = $booking_price*$tax_vat;
$booking_total_price = $booking_price+$booking_price_vat;
$booking_data = array(
'car_id' => $car_id,
'car_slug' => $car->slug,
'vehicle' => $car->title,
'start_location' => $this->input->post('start_location'),
'start_date' => $this->input->post('start_date'),
'start_time_hour' => $this->input->post('start_time_hour'),
'start_time_min' => $this->input->post('start_time_min'),
'return_location' => $this->input->post('return_location'),
'end_date' => $this->input->post('end_date'),
'end_time_hour' => $this->input->post('end_time_hour'),
'end_time_min' => $this->input->post('end_time_min'),
'discount' => '',
'start_location_name' => $data['locations'][$this->input->post('start_location')]['name'],
'return_location_name' => $data['locations'][$this->input->post('return_location')]['name'],
'start_date_time' => $this->input->post('start_date').' at '.$this->input->post('start_time_hour').$this->input->post('start_time_min'),
'return_date_time' => $this->input->post('end_date').' at '.$this->input->post('end_time_hour').$this->input->post('end_time_min'),
'total_days' => $total_days,
'total_price' => format_currency($booking_total_price)
);
$this->Booking_model->set_booking_data($booking_data);
}
}
?>
和Booking_model.php:
<?php
Class Booking_model extends CI_Model
{
function __construct()
{
parent::__construct();
}
function reset_booking_data()
{
$this->session->unset_userdata('booking');
}
function set_booking_data($data)
{
$booking_data = array();
$booking_data['booking'] = array();
$booking_data['booking'] = $data;
// put our booking in the cart
$this->session->set_userdata($booking_data);
}
function save_booking_data($data)
{
if(isset($data['id']))
{
$this->db->where('id', $data['id']);
$this->db->update('orders', $data);
return $data['id'];
}
else
{
$this->db->insert('orders', $data);
return $this->db->insert_id();
}
}
function get_booking_data()
{
$booking = $this->session->userdata('booking');
return $booking;
}
function is_booking_data()
{
$booking = $this->session->userdata('booking');
if(!$booking)
{
return false;
}
else
{
return true;
}
}
function orders($data=array(), $return_count=false)
{
if(empty($data))
{
//if nothing is provided return the whole shabang
$this->get_all_orders();
}
else
{
//grab the limit
if(!empty($data['rows']))
{
$this->db->limit($data['rows']);
}
//grab the offset
if(!empty($data['page']))
{
$this->db->offset($data['page']);
}
//do we order by something other than category_id?
if(!empty($data['order_by']))
{
//if we have an order_by then we must have a direction otherwise KABOOM
$this->db->order_by($data['order_by'], $data['sort_order']);
}
if($return_count)
{
return $this->db->count_all_results('orders');
}
else
{
return $this->db->get('orders')->result();
}
}
}
function get_all_orders()
{
//sort by alphabetically by default
$this->db->order_by('id', 'DESC');
$result = $this->db->get('orders');
return $result->result();
}
}
?>
我的$booking_data
var_dump
輸出為:
array(1) {
["booking"]=> array(18) {
["car_id"]=> string(1) "7"
["car_slug"]=> string(19) "audi-r8-v10-spyder1"
["vehicle"]=> string(16) "Aston Martin DB9"
["start_location"]=> string(20) "premiere-velocity-hq"
["start_date"]=> string(8) "23/09/15"
["start_time_hour"]=> string(2) "10"
["start_time_min"]=> string(2) "00"
["return_location"]=> string(18) "birmingham-airport"
["end_date"]=> string(8) "24/09/15"
["end_time_hour"]=> string(2) "10"
["end_time_min"]=> string(2) "00"
["discount"]=> string(0) ""
["start_location_name"]=> string(20) "Premiere Velocity HQ"
["return_location_name"]=> string(18) "Birmingham Airport"
["start_date_time"]=> string(16) "23/09/15 at 1000"
["return_date_time"]=> string(16) "24/09/15 at 1000"
["total_days"]=> int(1)
["total_price"]=> string(8) "£744.00"
}
}
您需要初始化會話庫以啟動CI會話。 在控制器中使用它。
$this->load->library('session');
或者,您可以將其添加到自動加載配置中,以便始終加載會話。 確保同時在配置中設置會話密鑰,否則CI會話將無法工作。 如果記憶對我有用。
