.htaccess - How to perform htaccess rewrite -

here summary of problem.

i have created facebook button. works correctly of time, not when following link somebody's actual "like" post. seems facebook adding more info url. instance, have

www.example.com/blog.php/6

but facebook adds

www.example.com/blog.php/6?fb_action_ids=10201090685057512&fb_action_types=og.likes&fb_source=aggregation&fb_aggregation_id=288381481237582

when user follows link mysql syntax error. if follow first link there no problem. thought strip off text url.

i created .htaccess file , placed in root directory on godaddy. tried several different rewrites.

nothing has worked. latest thought tried: options +followsymlinks
rewriteengine on
rewritecond %{query_string} ^(.*&)?fb_action_ids=
rewriterule ^(.*)$ $1?%1 [r=301]

do need change .htaccess file or there way solve problem?

thanks help.
