The code below is for an action called {{headings}}. It uses the css modification for the floating boxes suggested by DotMG (see bottom of this page). Use is >>{{headings}}>> where it'll provide a list of headings on the page on the right hand side of the page. The exception to this is that any heading (such as a page title) with 6 "=" signs will not be on the list. Original code (before considerable modification) was from a suggestion at wikini for TOC code.

Save the following code as actions/headings.php...
<?php
/*
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+ REVISED 12May05 (c) GMBowen to turn into a headings lister for the page. This modification +
+ ignores titles between 6 equal signs, removes the active links, etc. Released under GPL    +

DotMG's suggestion for changing the css code (from WikkaCSS) is....
min-width and max-width
You should not use fixed width in .floatr and .floatl classes. Instead, I suggest the use of max-width and min-width :
.floatl {float: left; margin: 0.5%; padding: 0.5%; background: #EEE; min-width: 100px; max-width: 300px;}
.floatr {float: right; margin: 0.5%; padding: 0.5%; background: #EEE; min-width: 100px; max-width: 300px;}

Try with the code <<{{calendar}}<<

I'm using a virtually unmodified Wikka Wakka Wiki 1.1.6.0 and this doesn't work for me. When I write ""{{headings}}"" or "">>{{headings}}>>"" and then press 'store' I get a "page can not be found for PageName/edit, and then viewing the page gets the same, so I have to revert to an older version.

um, hmmm. I too am using it on a virtually unmodified version of wikka 1.1.6.0 (well, the header and footer have been modded since I installed "headings" but it did work before). I'm afraid I don't have any suggestions. Did you change the CSS code as recommended (and ya, I know that shouldn't matter if you're not doing it using the > brackets). If you figure out what's goofing up, I'd appreciate it if you posted it here. Thanks.

I didn't change the CSS code as I realised it didn't matter...

What appears to be the problem is that if I put ""{{headings}}"" anywhere after text on the page (except after the header), it gives me a "page not found" error.

Also it doesn't just show the forced link text, it shows the link and the forced link text

What happens if you put {{headings}} at the very top of the page (which is the only place I've tried it actually....and my server is currently unreachable from where I am so I can't play with it) and then different headings (=====hiya=====, ====there====, ===stranger===....on different lines of course). Oh, and the links aren't supposed to be "live".....it's just a list. Live links require edits to wikka core and I was just trying to get a list. If you're looking for TOC stuff, see MindWikiTOC that was just posted today. It creates live links. gmb

If I put {{headings}} at the top it's fine, if i put it below a header it's fine. If it's after normal plain old text, the page fails.

What I meant by forced link text is that if you have a forced link as part of a header it shows something like [[http://www.blah.com/ blah]], in the list, rather than just "blah". I don't know whether that would require changes to core though.

I'll have a look at MindWikiTOC too, thanks for the heads-up.
