You have to load the urlhelper to access that function. Either you add
您必须加载urlhelper 才能访问该功能。要么你添加
$this->load->helper('url');
somewhere in your controller.
在你的控制器的某个地方。
Alternately, to have it be loaded automatically everywhere, make sure the line in application/config/autoload.phpthat looks like
或者，要让它在任何地方自动加载，请确保application/config/autoload.php中的行看起来像
$autoload['helper'] = array('url');
has 'url'in that array (as shown above).

You need to load the helper before loading the view somewhere in your controller.
在将视图加载到控制器中的某个位置之前，您需要加载助手。
But I think here you want to use the function site_url()
但我想在这里你想使用这个功能 site_url()
Before you load your view, basically anywhere inside the method in your controller, add this to your code :
在加载视图之前，基本上在控制器方法内的任何位置，将其添加到您的代码中：
$this->load->helper('url');
$this->load->helper('url');
Then use the function site_url().
然后使用函数 site_url()。

first you have to give echo to display base url. Then change below value in your autoload.php which will be inside your application/config/ folder.
$autoload['helper'] = array('url');then your issue will be resolved.
首先，您必须给 echo 以显示基本网址。然后在您的 autoload.php 中更改以下值，该值将位于您的 application/config/ 文件夹中。
$autoload['helper'] = array('url');那么您的问题将得到解决。

Check that you are extending CI_Controllerclass in your controller and in the view you have to echo base_url($path)function, otherwise it will not work.
检查您是否CI_Controller在控制器中扩展类，并且在您必须echo base_url($path)运行的视图中，否则它将无法工作。

$base_url = load_class('Config')->config['base_url'];
<?php echo $base_url ?>
and call it in your code..
并在您的代码中调用它..
