Are you looking for a way to add iFrames to the TinyMCE editor? While there’s probably a plugin for this, we have created a quick code snippet that you can use to support iFrames in editor in WordPress.
All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:
add_filter('tiny_mce_before_init', create_function( '$a','$a["extended_valid_elements"] = "iframe[id|class|title|style|align|frameborder|height|longdesc|marginheight|marginwidth|name|scrolling|src|width]"; return $a;') );
