codeigniter中的奇怪链接行为

Question

This is one of those problems that make me question my sanity. I'm using php, codeigniter framework, removing index.php from URL with mod rewrite in htaccess.

I'm at this address

http://localhost/health/users/bob/progress/

I click a link that takes me to

http://localhost/health/users/bob/progress/01-04-15

Then I click on a link that takes me back to

http://localhost/health/users/bob/progress/

Now here's the strange thing. I click on the same link that earlier took me to

http://localhost/health/users/bob/progress/01-04-15

But instead, now it's taking me to

http://localhost/health/users/bob/progress/progress/01-04-15

I've gone through the steps a dozen times now. This is definitely the behavior it's giving me. It even happens when I do a full refresh. I actually have to visit a different address, then return to get the link at

http://localhost/health/users/bob/progress/

to work properly again. I'm guessing it's either related to the mod rewrite, or some other rewrite behavior in the codeigniter framework.

I'm pretty sure you are using a relative path for the link that goes something like:

<a href="/somerelativepath">link here</a>

I would suggest that you use CI's base_url instead so that the link becomes absolute:

<a href="<?=base_url()?>/nowabsolutepath">link here</a>

the base_url is set on your configuration file. Please let us know how it goes!
