passing an encoded url ..

[eluser]/larry[/eluser]
I have a controller called filter that basically sets up a redirect to another
controller called filterlist. It encodes a url as one of it's arguments. filterlist is then set up to do pagination:

filter does this:

$val = urlencode($filter_val);
redirect("/widget/filterlist/$val/$fld");

the resulting url then looks like this:
http://my.local/widget-admin-codeigniter...l_addr_url

What I get is this error:

The requested URL /widget-admin-codeigniter/index.php/widget/filterlist/http://ajaxian.com/index.xml/xml_addr_url was not found on this server


I saw that I can set up Codeigniter to use parameters instead of the usual
url scheme it uses, but it appears I can't do it both ways, and I think doing that
will change the browser caches the pages as well, so I'm not sure that's a good approach.
I guess you can't mix the two ? Otherwise I would try maybe:

widget/filterlist/$fld/?val=$val

The way around it seems to be to use a session, which is not ideal, but the site is an admin interface and won't get any real traffic.

Any ideas appreciated ...

Looks like passing a full url in the query is way too messy. You should try one of your other options.

Session is a good idea. You could set a flashdata item so that way it would be auto destroyed.

You may just want to turn on the get input values and pass it in the query param thou.

It sounded like turning on the $_GET parameters makes the usual code igniter type URLs to not work ?

[eluser]louis w[/eluser]
They can work in tandem. I turned on query strings for the admin portion of my application.

In your config:

Code:

$config['enable_query_strings'] = TRUE;
$config['directory_trigger'] = '';
$config['controller_trigger'] = '';
$config['function_trigger'] = '';

Then in your controller you just reference:

Code:

$val = $this->input->get('val');

I was just thinking thou, have you thought about base64 encoding the url. That way it would just be a a-z0-9 string.

[eluser]/larry[/eluser]
I tried what you suggested and it didn't work, I get nothing for:

http://my.local/widget-admin-codeigniter...?val=green


base 64 won't have any forward slashes ?

[eluser]louis w[/eluser]
Shouldn't. Check it out:

http://www.php.net/base64_encode

Also check out the comments, i see some down there for urls.

I started using it as it seems like it was working, but then there was "=" at the end of the encoded string and I got an error saying illegal characters in URL

Check out the first comment on the php page. Looks like someone has a little function to str_replace the =

[eluser]/larry[/eluser]
Using ',' instead of '=' like it shows there didn't work, but I tried using '.' instead and that seems to work. Thanks alot, I was almost going to try hexidecimal

[eluser]/larry[/eluser]
but then someone wrote this:

"a note on URI -safe base64.
Simply replacing + = and / with _ - and . doesn't work as the base64_encode function will insert \r \n chars as well which are not URI-safe. So unless we have a base64encode function that does not insert any newline and padddings, the output can never be URI -safe."
