SID-00242: Displaying preference values

Status:	Answered	TWiki version:	4.1.2	Perl version:
Category:	CategorySearch	Server OS:		Last update:	16 years ago

I would like to show all topics where ALLOWTOPICCHANGE has been set and to also display what users this permission was granted to. Using various types of searches I am able to get the topic names to show, but not the values (ie users). Any ideas on how to do this?

Thank you, Fred

Discussion and Answer

You can search and apply a RegularExpression pattern to pull the value of ALLOWTOPICCHANGE. Here is an example with renamed variable for obvious reasons:

• Set DEMOTOPICCHANGE = FredBarnfield, PeterThoeny

Now do a search. Here we search just on the current page, but you can search for all pages:

• SID-00242's DEMOTOPICCHANGE: FredBarnfield, PeterThoeny

Do a "raw view" to see how this works. The regular expression needs to be tweaked if you want to catch also topic preferences (set in "more" screen).

See also VarSEARCH, FormattedSearch, RegularExpression, TWikiPreferences, TWikiAccessControl.

Thank you Peter. Did forget to mention that I have set the topic preferences in the "more" screen. I still can't get the search to work right yet. Below is my latest attempt where I used the $pattern expression you suggested:

%SEARCH{"%META:PREFERENCE.*[A]LLOWTOPICVIEW.*" nonoise="on" format="|$topic|$pattern(.*\* *Set *ALLOWTOPICVIEW *= *([^\n\r]*).*) |" }%

Thank you for any light that can be shed. Fred

Sorry, I didn't put the code in right above:

%SEARCH{"%META:PREFERENCE.*[A]LLOWTOPICVIEW.*" nonoise="on" format="|$topic|$pattern(.*\* Set *ALLOWTOPICVIEW *= *([^\n\r]).*) |" }%

Sorry, I checked, you can search for topic preferences, but you can't show the values of meta data unless exposed in FormattedSearch. At this time, a limited number of meta data can be shown, such as topic info ($rev, $date etc) and form fields ($formfield()).

If you are a Perl developer you could contribute a $preference() variable to the SEARCH format="" parameter.

Thanks so much for your help! Wish I were a Perl developer so I could help out, but I'm a newbie to that side, just now learning a little php. Maybe some day I'll get there! Thanks again.
