Question

当我第一次加载我的应用程序时，我收到以下错误

A PHP Error was encountered
Severity: Notice

Message: Undefined index: user_full_name

Filename: templates/header.php

Line Number: 85

Backtrace:

File: /home/xyz/app/application/views/templates/header.php
Line: 85
Function: _error_handler

视野中的代码

<? if ($this->session->userdata['user_full_name'] == "" || $this->session->userdata['user_full_name'] == null): ?>
something something

控制器

public function __construct() {

    parent::__construct();
    $this->load->library('session');
    $this->load->model('home_model');
    $this->load->model('user_model');        
}

为什么会这样。为什么我会收到一条错误，指出该变量无法识别

感谢 Krish

如上面的Clive所述，我做了以下更改以纠正错误

更改此

<? if ($this->session->userdata['user_full_name'] == "" || $this->session->userdata['user_full_name'] == null): ?>

到

<? if (!isset($this->session->userdata['user_full_name'])): ?>

Codeigniter在会话开始之前抛出错误
