How do I ban certain passwords?

Use the following in your local/config.php:

 
## Invalidate particular password(s)
$ForbiddenPasswords = array('secret', 'hushhush');
if (in_array(@$_POST['authpw'], $ForbiddenPasswords)) {
  unset($_POST['authpw']);
}

Why doesn't the PmWiki default skin include a link to AllRecentChanges?

For most of the wikis I run, the wikigroups are almost entirely disconnected -- i.e., each department or student organization has its own group. In these situations the per-group RecentChanges makes a lot more sense than AllRecentChanges.

(Yes, for me as the admin I tend to use AllRecentChanges, but the vast majority of people browsing the site are interested only in a single wikigroup, and probably don't even realize that the separate groups are all part of the same wiki. At least, that's what led me to create wikigroups to begin with.) --Pm

How do I add a Google searchbox to my wiki?

Use the following Custom Markup:

Markup('googlesearch', 'directives', '/\\(:googlesearch:\\)/e',
  "'<:block>'.Keep(\"<a href='http://www.google.com'><img
  src='http://www.google.com/logos/Logo_40wht.gif' border='0'
  alt='Google' title='Google' /></a><form class='wikisearch'
  style='margin:0px; margin-bottom:20px;'
  action='http://www.google.com/search' method='get'><input
  type='text' class='wikisearchbox' title='Search Google' name='q'
  size='20' maxlength='255' value='' /><input type='hidden' name='hl'
  value='en' /><input type='submit' class='wikisearchbutton'
  name='btnG' value='Go' /></form>\")");

This will add a (:googlesearch:) directive.

How do I add a Google searchbox to my wiki that returns search results for my site?

Use the following Custom Markup:

Markup('googlesearch', 'directives', '/\\(:googlesearch:\\)/e',
  "'<:block>'.Keep(\"Search Google: <form class='wikisearch'
  style='margin:0px; margin-bottom:20px; display:inline; '
  action='http://www.google.com/custom' method='get'><input
  type='text' class='wikisearchbox' title='Search Google' name='q'
  size='20' maxlength='255' value='' /><input type='hidden' name='hl'
  value='en' /><input type='hidden' name='sitesearch'
  value='www.pmwiki.org' /><input type='submit' class='wikisearchbutton'
  name='btnG' value='Go' /></form>\")");

Of course you'll need to change the value of sitesearch to your site.

How do I disable the "!" (single-bang) markup for Level-1 Headings (<h1>)?

Use the following in your local/config.php:

Markup('^!', 'block',
  '/^(!{1,6})\\s?(.*)$/e',
  "'<:block><div class=\"someclass'.strlen('$1').PSS('\">$2</div>')");

How do I hide a comment block within some wiki markup.

The %comment% wikistyle sends your comment text to the browser in a block with a "display:none;" attribute, meaning the comment can be viewed in the page's source. To keep your block of text from being sent to the browser at all, you can use conditional markup:

(:if false:)
This line doesn't get rendered on the page.
Nor does this one.
(:if:)

What cookies does PmWiki set? How can I clear PmWiki has set?

Typically PmWiki just sets two cookies; one for the browsing session and one for the Author Name. PmWiki also comes with a script that uses a cookie to identify the location of a preferences page. Some cookbook recipes and skins also use cookies.

You can view the cookies a site has set using the "View Cookies" bookmarklet here:

You can clear a site's cookies using the "Zap Cookies" bookmarklet here:

What is the "order" parameter? Is it a query string parameter? What are valid order values?

It's a pagelist parameter, which means it can be part of a search query, specified in the (:pagelist:) directive, or given as a url (query string) parameter.

Inside a wiki page, one can do

and get a list of the ten most recently modified Cookbook pages.

Then, url query string parameters can be used to override the settings in the (:pagelist:) directive, thus the url

overrides the (:pagelist:) settings and displays the first five pages in the Cookbook group in alphabetical sequence.

Finally, one can use these in a search box, thus entering a search query of

returns all of the pages in the cookbook, ordered by last modification time.

Any page attribute can be used as an order value; the common ones are

order=name         page's name
order=title        page's title
order=time         last modification time
order=ctime        page creation time
order=author       last author
order=size         size of markup in bytes

I want to have a "Today" link on my site's Home Page, like [[D2006/20060206|Today]]

You would need pmwiki version 2.1.beta15 or higher for this:

Define a page variable in config.php:

# Add a page variable w/ today's date formatted as YYYYMMDD. $FmtPV['$Today'] = 'strftime("m%d", time() )';

Then you can write your link as
