base_url（）函数在codeigniter中不工作 [英] base_url() function not working in codeigniter
问题描述
我正在使用codeigniter开发一个我们的应用程序。我试图使用base_url（）函数，但它显示空的结果。我已经使用自动加载助手通过自动加载文件，但后来它似乎没有工作。我也定义了基本常数，但都是徒劳的。请帮助。

为了使用 base_url （），您必须首先加载URL助手。这可以在 application / config / autoload.php （在第67行或其后）执行：
$ autoload ['helper'] = array（'url'）;
或者，手动：
$ this-> load-> helper（'url'）;
一旦载入，请务必记住 base_url / code>不会隐式打印或回显任何东西，而是返回要打印的值：
base_url（）;
还记得返回的值是配置文件中提供的网站的基本网址。 CodeIgniter也将在配置文件中包含一个空值：
application / config / config.php，第13行
I am developing a we application using codeigniter. I am trying to use base_url() function but it shows empty results. I have used autoload helper through autoload file, but then too it doesn't seem to work. Also I had defined base constants but all in vain. Please help.
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title><?php echo $title; ?></title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<link rel="stylesheet" href="<?php echo base_url();?>/css/template/default.css" type="text/css" />
<script type="text/javascript">
//<![CDATA[
base_url = '<?= base_url();?>';
//]]>
</script>
</head>
In order to use base_url(), you must first have the URL Helper loaded. This can be done either in application/config/autoload.php (on or around line 67):
$autoload['helper'] = array('url');
Or, manually:
$this->load->helper('url');
Once it's loaded, be sure to keep in mind that base_url() doesn't implicitly print or echo out anything, rather it returns the value to be printed:
echo base_url();
Remember also that the value returned is the site's base url as provided in the config file. CodeIgniter will accomodate an empty value in the config file as well:
If this (base_url) is not set then CodeIgniter will guess the protocol, domain and path to your installation.
application/config/config.php, line 13
