CodeIgniter - URI Disallowed Characters

Question

I had issue of @ which I added in $config['permitted_uri_chars'] as you can see below:

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_@\-';

BUt here is my URL

http://mydomain.com/awarenessroom/facebook_image_share/aHR0cDovL2Rldi5lanVpY3lzb2x1dGlvbnMuY29tL3Jla2xhaW1wYWtpc3Rhbi5jb20vdXBsb2Fkcy9hd2FyZW5lc3Nfcm9vbS9pbWFnZXMvOTEwNzA4ODI3VG9yIERheSBaYW5qZWVyLmpwZw==

and it says "The URI you submitted has disallowed characters.", even if I add = in config, still not working. Can anybody let me know what is required exactly by CI in config to get resolved for URI to be working?

the `==` at the last you need to user url encode if you plan passing it to the uri. — tomexsans, Apr 29 '13 at 05:49
I think you are encoding some thing so use this rtrim(base64_encode($string_name),'=') — Venkata Krishna, Apr 29 '13 at 05:56
@Umer use the above one which i specified while encoding.... — Venkata Krishna, Apr 29 '13 at 06:52
because in the end to remove those '==' when you encode any string using base64_encode right side you will get '==' those are not allowed in url thats why... — Venkata Krishna, Apr 29 '13 at 07:13
venkat, = cannot be removed which are appended by base64_encode. After excluding = for the sake of URI to be working, we will not be able to get exact value using base64_decode — Umer, Apr 29 '13 at 10:22

As per your info you are using base64_encode so this i will suggest to you because i am following the same in my web application

$encode_string = "google.com";

$result = rtrim(base64_encode($encode_string ),'=');

$decoded_string = base64_decode($result);

Please use url_encode(base64_encode(string)) and then decode it. It will help you for sure.
