我正在使用codeigniter开发物业管理系统。我在控制器中的一个函数中定义的每个$ data ['']都得到了非法偏移错误。同一控制器中的其他功能正常工作没有任何问题。我尝试了为'illegel offest'错误提供的exisitng答案，但没有一个回答我的问题。这是我的代码： -
Model（model_season.php）： -
function insertSeason($data){
$season_flag = '';
$this->db->insert("season",$data);
if ($this->db->affected_rows()>0){
$season_flag = true;
} else {
$season_flag = false;
}
return $season_flag;
}
function getAllSeason(){
$this->db->select('*');
$this->db->from('season');
$this->db->join('property', 'property.PropertyID = season.SeasonID', 'inner');
$this->db->order_by('season.SeasonID', 'DESC');
//$this->db->from('season');
//$this->db->order_by("SeasonID", "DESC");
$query = $this->db->get();
return $query->result();
}
这是控制器（season.php）： -
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Season extends CI_Controller{
function __construct(){
parent::__construct();
$this->load->model('model_season');
$this->load->model('model_property');
$this->load->model('user');
}
function index(){
if ($this->session->userdata('logged_in'))
{
$this->load->helper(array('form'));
$this->lang->load('common');
$this->lang->load('season');
$session_data = $this->session->userdata('logged_in');
$data['user_name'] = $session_data['user_name'];
$data['property_list'] = $this->model_property->GetAllProperty();
$data['season_list'] = $this->model_season->getAllSeason();
$this->load->view('backend/header');
$this->load->view('backend/add_season_view',$data);
$this->load->view('backend/footer');
} else {
redirect('login', 'refresh');
}
}
function navigateToSeason($data_){
if ($this->session->userdata('logged_in'))
{
$this->load->helper(array('form'));
$this->lang->load('common');
$this->lang->load('season');
$session_data = $this->session->userdata('logged_in');
$data['user_name'] = $session_data['user_name'];
$data['property_list'] = $this->model_property->GetAllProperty();
//var_dump($this->model_season->getAllSeason());
$data['season_list'] = $this->model_season->getAllSeason();
if ($data_ == 1){
$data['message'] = "success";
}
if ($data_ == 0){
$data['message'] = "error..";
}

$this->load->view('backend/add_season_view',$data);
$this->load->view('backend/footer');

}
}
function addSeason(){
echo 'function test pass..';
$username = $this->input->post('username');
$this->load->library('form_validation');
$validaton_options = array (
array(
'field' => 'season_selected_property',
'label' => 'Property',
'rules' => 'trim|numeric|required|xss_clean'
),
array(
'field' => 'season_title',
'label' => 'Season Title',
'rules' => 'trim|required|xss_clean'

array(

array(

);
$this->form_validation->set_rules($validaton_options);
//start form validation
if ($this->form_validation->run() == true){
$NewSeason = array(
"SeasonPropertyID"=> $this->input->post('season_selected_property'),
"SeasonTitle"=>$this->input->post('season_title'),
"StartDate"=>$this->input->post('season_start_date'),
"EndDate"=>$this->input->post('season_end_date')
);
//check - add to database
if ($this->model_season->insertSeason($NewSeason)){
redirect('season/navigateToSeason/1','refresh');
} else {
redirect('season/navigateToSeason/0','refresh');
}
// end database add
} else {
if ($this->session->userdata('logged_in'))
{
$this->load->helper(array('form'));
$this->lang->load('common');
$this->lang->load('season');
$session_data = $this->session->userdata('logged_in');
$data['user_name'] = $session_data['user_name'];
$data['property_list'] = $this->model_property->GetAllProperty();
$data['season_list'] = $this->model_season->getAllSeason();
$this->load->view('backend/header');
$this->load->view('backend/add_season_view',$data);
$this->load->view('backend/footer');
} else {
redirect('login', 'refresh');
}
}
//end form validation
}//end function
public function date_valid($date)
{
$parts = explode("-", $date);
if (count($parts) == 3) {
if (checkdate($parts[1], $parts[2], $parts[0]))
{
return TRUE;
}
}
$this->form_validation->set_message('date_valid', 'The Date field must be yyyy-mm-dd');
return false;
}
}
?>
以下是我的观点： -
<?php if (isset($message) && $message != ''){
echo $message;
}
if (isset($user_name) && $user_name != ''){
echo $user_name;
}
if (isset($season_list))
{
foreach ($season_list as $season){
echo $season->SeasonTitle;
echo $season->StartDate;
echo $season->EndDate;
}
}
?>

答案 0 :(得分：0)
解决了问题。问题是我的控制器中的navigateToSeason函数（$ data）中的参数。我将perameter $ data重命名为$ data_，现在它运行顺畅。请确保为每个功能选择不同的参数名称。
