beforeSaveHandler($text, $topic, $web, $meta )

• $text - text with embedded meta-data tags
• $topic - the name of the topic in the current CGI query
• $web - the name of the web in the current CGI query
• $meta - the metadata of the topic being saved, represented by a TWiki::Meta object.

This handler is called each time a topic is saved.

NOTE: meta-data is embedded in $text (using %META: tags). If you modify the $meta object, then it will override any changes to the meta-data embedded in the text. Modify either the META in the text or the $meta object, never both. You are recommended to modify the $meta object rather than the text, as this approach is proof against changes in the embedded text format.

Since: TWiki::Plugins::VERSION = '1.010'
