To use base_url()(shorthand), you have to load the URL Helperfirst

要使用base_url()(速记),您必须加载第URL Helper一个

$this->load->helper('url');

Oryou can autoload it by changing application/config/autoload.php

或者您可以通过更改自动加载它application/config/autoload.php

Orjust use

或者只是使用

$this->config->base_url();

Same applies to site_url().

同样适用于site_url().

Also I can see you are missing echo(though its not your current problem), use the code below to solve the problem

我也可以看到你丢失了echo(虽然它不是你当前的问题),使用下面的代码来解决问题

<link rel="stylesheet" href="<?php echo base_url(); ?>css/default.css" type="text/css" />

I know this is very late, but is useful for newbies. We can atuload url helper and it will be available throughout the application. For this in application\config\autoload.php modify as follows -

我知道这很晚了,但对新手很有用。我们可以 atuload url helper,它将在整个应用程序中可用。为此在 application\config\autoload.php 中修改如下 -

$autoload['helper'] = array('url');

You need to load the URL Helper in order to use base_url(). In your controller, do:

您需要加载 URL Helper 才能使用base_url(). 在您的控制器中,执行以下操作:

$this->load->helper('url');

Then in your view you can do:

然后在您看来,您可以执行以下操作:

echo base_url();

Just load helper class

只需加载助手类

$this->load->helper('url');

thats it.

就是这样。

You need to add url helper in config/autoload

您需要在 config/autoload 中添加 url helper

$autoload['helper'] = array('form', 'url', 'file', 'html'); <-- Like This

Then you can use base_url or any kind of url.

然后你可以使用 base_url 或任何类型的 url。
