[英]base_url not loading in codeigniter
问题描述
I am using this in my viewregistration.php file 
我在我的viewregistration.php文件中使用它
<html>
<head>
<link rel="stylesheet" type="text/css" href="<?php echo $base_url; ?><?php echo $css; ?>reg_style.css" />
<link rel="stylesheet" type="text/css" href="<?php echo $base_url; ?><?php echo $css; ?>style.css" />
</head>
<body>
<?php $this->load->view('include/header');?>
<?php $this->load->view('registration_view.php');?>
<?php $this->load->view('include/footer');?>
</body>
</html>
And I am calling it in my conltroller as 我在控制器中称它为
$data['title']= 'Registration';
$this->load->view("viewregistration.php", $data);
And in my controller I am using 在我的控制器中
parent::__construct();
$this->load->helper('url');
$this->load->helper('form');
$this->load->database();
$this->load->model('user_model');
$this->load->model('systemdata');
$this->data['css'] = $this->systemdata->get_css_filespec();
$this->data['scripts'] = $this->systemdata->get_scripts_filespec();
$this->data['base_url'] = $this->systemdata->get_base_url();
But the css file is not loading. 但是css文件未加载。 It show some error like 它显示出一些错误，例如
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: base_url
and 和
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: css
What I am doing wrong? 我做错了什么？ I have used autoload url helper. 我已经使用了自动加载网址帮助程序。 But the result remains same. 但是结果仍然相同。

Your variables aren't defined because you're not actually passing them to your view. 您没有定义变量，因为您实际上没有将它们传递给视图。 $data and $this->data are not the same thing. $data和$this->data不是同一件事。
Here, you are correctly passing the $data array to your view: 在这里，您可以正确地将$data数组传递给视图：
$data['title']= 'Registration';
$this->load->view("viewregistration.php", $data);
But notice here how you're assigning your variables to $this->data , which never gets passed to the view: 但是请注意，您是如何将变量分配给$this->data ，而该变量永远不会传递给视图：
$this->data['css'] = $this->systemdata->get_css_filespec();
$this->data['scripts'] = $this->systemdata->get_scripts_filespec();
$this->data['base_url'] = $this->systemdata->get_base_url();
You either need to assign your variables to $data or pass $this->data to your view. 您需要将变量分配给$data或将$this->data传递给视图。

I dont think this line is necessary. 我认为这行不是必要的。
$this->data['base_url'] = $this->systemdata->get_base_url();
What you can do instead, is this. 您可以做的是这个。
<link rel="stylesheet" type="text/css" href="<?php echo base_url($css.'reg_style.css'); ?>" />
base_url() is a CI function that gives you, the base url. base_url（）是一个CI函数，为您提供基本URL。
