codeigniter: why is that when i echo base_url() in an href attribute of an anchor tag, it echoes twice

anchor, base-url, codeigniter, php, url

Solution

There are three reasons I'm aware about that can cause this.

The first one is when something wrong is written in `config.php` on line 17 `$config['base_url'] = '';` - it better be left empty, just like when you download CI.

The second one is if you have set `$config['base_url']` value to something without prefixing it with `http://` or other protocol.

The third one is if you have set `base` `href` somewhere:

<base href="http://www.mysitedomainname.com/" />

When you need to link to some other page, you should use `site_url()`, `base_url()` can be used to link stylesheets, js, img src attributes and other real URL's. The reason is pretty simple, `base_url()` does not include the `index_page` value set in `config.php`.

Problem

so basically when i echo the codeigniter function base_url() in the href attribute of an anchor tag, it appears to echo it out twice. Example: ``` <a href="<?php echo base_url(); ?>">somelink</a> ``` and the above, if you inspect it your chrome browser shows this: ``` <a href="www.mysitedomainname.com/www.mysitedomainname.com/">somelink</a> ``` "mysitedomainname.com" is just a name i made up for this example. Any reason why this is happening?
