遇到错误-在localhost上提交表单时找不到404页面。提交表单后链接看起来像这样-http://localhost/ci/index.php/news/localhost/ci/index.php/news/create

Answer 1

请按照以下步骤操作：

1。。您需要在自动加载文件中加载“ url_helper”，这是一种最佳做法，而不是在每个页面中编写。 路径（应用程序>配置> autoload.php）

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

2。。您需要在视图页面的顶部添加以下行。

<base href="<?php echo base_url(); ?>">
