Links to Controller methods: CodeIgniter

Question

I'm following this tutorial on CodeIgniter:

http://ie.mirror.twsweb-int.com/codeigniter/user_guide/tutorial/index.html

4th page of tutorial:

http://ie.mirror.twsweb-int.com/codeigniter/user_guide/tutorial/create_news_items.html

In the 4th page of the tutorial, he mentions that you should create your own successful entry page.

I want to create a link on the success.php that links back to the index page (calls news_index). IE in terms of URLs, I want a link that goes from

http://example.com/codeigniter/index.php/news/create

to

http://example.com/codeigniter/index.php/news/

How are dynamic URLs like that made on CodeIgniter?

Answer 1

First load the URL helper in your controller or Autoload file.

Then use the site_url() function and just pass news.

<?php echo site_url('news');?>

Answer 2

If you take a look at this page - http://ie.mirror.twsweb-int.com/codeigniter/user_guide/helpers/url_helper.html you can see how the site_url() function works.

You just echo site_url('controller/method/segment1/segment2/etc'); so if you wanted to link to the http://example.com/codeigniter/index.php/news/ page you can do

<?php echo site_url('news'); ?>

and if you wanted to link to the http://example.com/codeigniter/index.php/news/create you can do

<?php echo site_url('news/create'); ?>

Answer 3

您可以在config.php设置site_url/base_url并在autoload.php文件中autoload.php URL helper。

Answer 4

您可以在 codeigniter 文件的 routes.php 上配置它们。
