base_url() 函数在 codeigniter 中不起作用 [英] base_url() function not working in codeigniter
问题描述
在我的 web 应用程序中使用 codeigniter.我正在尝试使用 base_url() 函数，但它显示空结果.我还通过自动加载文件使用了自动加载助手，但它似乎也不起作用.我也定义了基本常量，但都是徒劳的.
In my web application using codeigniter. I am trying to use base_url() function but it shows empty results. I have also 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.
<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>
推荐答案
为了使用 base_url()，您必须首先加载 URL Helper.这可以在 application/config/autoload.php 中完成(在第 67 行或附近):
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');
或者，手动:
$this->load->helper('url');
一旦加载，请务必记住 base_url() 不会隐式打印或回显任何内容，而是返回要打印的值:
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();
还要记住，返回的值是配置文件中提供的站点的基本 URL.CodeIgniter 也会在配置文件中容纳一个空值:
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:
如果这个 (base_url) 没有设置，那么 CodeIgniter 会猜测你安装的协议、域和路径.
application/config/config.php，第 13 行
application/config/config.php, line 13
