I've searched the forums, but can't find too much... I've got a simple CMS in the works, and I'm trying to use a Back To Top link throughout my content

Code:

<a href="#top">Back To Top</a>

When it's clicked, it doesn't just put #top at the end of the current url like domain.com/controller/method#top instead it loads the homepage. This is because of the base tag which is necessary to load everything properly... if the href includes the current uri like

Code:

<a href="URI_STRING#top">Back To Top</a>
//had trouble getting the $this->uri->uri_string() function to show up in the link here,
//but you get the idea...

it works fine... but again, I'm creating this content through a CMS, and ultimately it will be the client managing this content.

I have 2 possible solutions to this problem. I can either use jQuery or preg_replace to prepend any links that have a # with the current uri string. Does anybody else have any ideas?

Thanks.

Edit: I decided to do the preg_replace method, and it works fine, but if anyone has any other ideas, or even ideas why the preg_replace method might not work, please let me know. Thanks.

You need a little more than uri_string. Use the URL helper and use site_url():

Code:

<a href="<?=site_url($this->uri->uri_string());?>#top">Back to Top</a>

Even better, use current_url():

Code:

<a href="<?=current_url();?>#top">Back to Top</a>

Thanks, I was asking more about if there was a way to make those links relative to the current uri, other than what I came up with. The more I think about it, the more I'm sure there isn't, so the solution I did is the best one, I think.
