I am using CKEditor (FCK) and I want to filter certain things from being used by users like (.com, <, >) symbols and words. Is there any plugin available for this or in which way i can do this? any help please..
Do you need this as interactive functionality (before post) or server-side after posting? The former will rely on JS, the latter on PHP. However JS can be circumvented, so a JS functionality would also require PHP backup.
CKEditor uses JS, so if you're looking to embed this functionality into the interface, I assume it will be JS. BUT, as mentioned, if you want to ensure CLEAN input to the DB, you need to use some string or preg* functions.
