Hello all, I intend to develop[*] a very simplified variant of the "stable version" concept: If the editing user has no authorization, replace any sensitive portions with a non-sensitive substitute - e.g. "{{Approved}}" becomes "{{Approval Candidate}}". [*] see "Re-inventing the wheel?" below The following simple flowchart probably illustrates my idea better than a verbose description would: +--------------+ | save request | +--------------+ | V /--------------------------------\ No | article text contains $cue [1] |-------------------------------------+ \--------------------------------/ | | | Yes | | V | /------------------------\ No +------------------------------+ | | user is authorized [2] |------->| replace $cue with $subst [1] | | \------------------------/ +------------------------------+ | | | | Yes | | | V | | +--------------+ | | | save article |<--------------------------------+---------------------+ +--------------+ [1] $cue and $subst are strings, read from an external TXT file (in future version, these variables might be arrays of strings) [2] authorization is handled via user rights (e.g. Bureaucrats, or custom group "Editors"; might be read from an external TXT file) Theoretically, this could all be very simple (maybe 10-20 LoC). However, there are a few concerns: #1 Re-inventing the wheel? I'm probably not the first person to think of this on-save substitution. However, I couldn't find an extension to build upon (which might be due to a lack of unique keywords to search for). #2 Preventing false positives How can I prevent unparsed occurrences of $cue from being substituted? For example, [[Template:Approval]] might contain usage notes with the template call wrapped in PRE tags - this obviously should not be replaced. Here's some very preliminary (pseudo-)code I quickly threw together - maybe could help me fill in the blanks: --------------- <?php $wgHooks['ArticleSave'][] = 'wfCheckApprovalAuthorization'; function wfCheckApprovalAuthorization(&$article, &$user, &$text, &$summary, $minor, $watch, $sectionanchor, &$flags) { $cue = "foo"; // to be read from external TXT file $subst = "bar"; // to be read from external TXT file $auth = "editors"; // to be read from external TXT file if( $text == $cue ) { // check for "contains", not "equals" if( in_array( $auth, $user->$permissions ) ) { // nonsense? str_ireplace( $cue, $subst, $text ); // nonsense? } } } ?> --------------- Sorry this message turned out to be so verbose. For whoever has read this far, I'd greatly appreciate any feedback! -- F.
