Can any one please help me how to sanitize google analytics code in WordPress Theme Options Page.
I am concerned about XSS if I simply use the code
$input['id'] = stripslashes( $input['id'] );
But at the same time, if I use the following code, it will strip out all the Tags.
$input['id'] = stripslashes(wp_filter_post_kses( $input['id'] ));
I read Otto comments about
wp_filter_post_kses - I think this deals with regular HTML, making sure that not bad Tags slips through, at same time it filters out Java Code, and so Google code will be striped out.
So please can some one tell me what is best practice on this issue. Thanks.
