wp_kses( string $string, array $allowed_html, array $allowed_protocols = array() )
Filters content and keeps only allowable HTML elements.
Description Description
This function makes sure that only the allowed HTML element names, attribute names and attribute values plus only sane HTML entities will occur in $string. You have to remove any slashes from PHP’s magic quotes before you call this function.
The default allowed protocols are ‘http’, ‘https’, ‘ftp’, ‘mailto’, ‘news’, ‘irc’, ‘gopher’, ‘nntp’, ‘feed’, ‘telnet, ‘mms’, ‘rtsp’ and ‘svn’. This covers all common link protocols, except for ‘javascript’ which should not be allowed for untrusted users.
