Hi there

There is nothing wrong with your explanation actually krishnakumar2k - I understood it. I've just encountered the same issue and found a solution elsewhere so thought I should let you know.

According to one of the answers in this post, CodeIgniter *purges* the $_REQUEST variable for security reasons. I assume it's related to the automatic input filtering described in the Codeigniter Manual here, but it's not specifically mentioned there either though. I am unsure whether setting

Code:

$config['global_xss_filtering'] = TRUE;

in config.php affects it or not (I have it set to TRUE in mine), but at least now you/we know why the $_REQUEST variable is not available.

Interestingly, I have the FB SDK library in my CIApplication/libraries/ folder and it seems to access the $_REQUEST variable fine, just not in views or controllers.

Was looking for the answer to the same question when I came across this post.

Cheers
Matt
