authors (intermediate)

This page describes the "variables" that are associated with pages. Page variables have the form {$variable}, and can be used in page markup or in certain formatting strings in PmWiki. For example, the markup "{$Group}" renders in this page as "PmWiki".

Note: Do not confuse these variables (set and used only in PmWiki pages) with PHP variables. Page variables can be read in PHP with the PageVar() function.

Note that these variables do not necessarily exist in the PHP code, because they have to be determined for a specific page. (However, they are usable in FmtPageName strings.)

There is also the form {pagename$variable}, which returns the value of the variable for another page. For example, "{MarkupMasterIndex$Title}" displays as "Markup Master Index".

Special references

Special referenced variables are used to specify the context of the variable when:

the variable is included into a destination (target) page
the variable is used in a sidebar, header, or footer

Prefixing the variable name with an asterisk (*) means the variable's value is related to the target page or main (body) page.

{*$PageVariablename} - prefixed by an asterisk (*) - value reflects target page context

Without the asterisk the variable's value is that in the page from which it originates, eg source page of include, sidebar, or header or footer.

{$PageVariablename} - retains value in source page context

Default page variables

The page variables defined for PmWiki are:

{$Action} - page's url action argument, as in "browse"

{$BaseName} - page's "base" form (stripping any prefixes or suffixes defined via $BaseNamePatterns) as in "PmWiki.PageVariables"

{$DefaultGroup} - default group name, as in "Main"

{$DefaultName} - name of default page, as in "`Home"

{$Description} - page's description from the (:description:) markup, as in "Documentation for "variables" that are associated with pages."

{$FullName} - page's full name, as in "PmWiki.PageVariables"

{$Group} - page's group name, as in "PmWiki"

{$Groupspaced} - spaced group name, as in "Pm Wiki"

{$LastModified} - date page was edited, as in "September 23, 2010, at 12:02 AM"

{$LastModifiedBy} - page's last editor, as in "simon"

{$LastModifiedHost} - IP of page's last editor, as in "202.37.32.2"

{$LastModifiedSummary} - Summary from last edit, as in "minor wording on special references"

{$LastModifiedTime} - time page was edited in unix-style timestamp, as in "1285192923" added version 2.2 beta 67

This can be used (preceded by '@') in {(ftime)} and other date/time markups.

{$Name} - page name, as in "PageVariables"

{$Namespaced} - spaced page name, as in "Page Variables"

{$PageUrl} - page's url, as in "http://fct11.ifi.uio.no/index.php?n=PmWiki.PageVariables"

{$PasswdRead} - "read" permissions for the page e.g. "(protected)"

{$PasswdEdit} - "edit" permissions for the page e.g. "(protected)"

{$PasswdAttr} - "attr" permissions for the page e.g. "(protected)"

{$RequestedPage} - page requested in URL, used on Site.PageNotFound. e.g. "PmWiki.PageVariables"

{$SiteGroup} - default group name for e.g. RecentChanges, as in "Site"

{$Title} - page title (may differ from Name), as in "Page specific variables"

{$Titlespaced} - either the page title (if defined), or the spaced page name, as in "Page specific variables"

In addition to the above, there are some page-invariant variables available through this markup:

{$Author} - the name of the person currently interacting with the site, as in ""

{$AuthId} - current authenticated id, as in "" Please note the lower case 'd'. {$AuthID} returns nothing

{$Version} - PmWiki version, as in "pmwiki-2.2.19"

{$VersionNum} - The internal version number, as in "2002019"

{$ScriptUrl} - The url to the pmwiki script, as in "http://fct11.ifi.uio.no/index.php"

Custom page variables

You may add custom page variables as a local customization. In a local configuration file or a recipe script, use the variable $FmtPV:

$FmtPV['$VarName'] = "'variable definition'";
$FmtPV['$CurrentSkin'] = '$GLOBALS["Skin"]';
$FmtPV['$WikiTitle'] = '$GLOBALS["WikiTitle"]';

Defines new Page Variable of name $CurrentSkin, which can be used in the page with {$CurrentSkin} (also for Conditional markup). It's necessary to use the single quotes nested inside double-quotes as shown above (preferred) or a double-quoted string nested inside single-quotes like '"this"'.

If you want to have a Page Variable that returns the currently used password (more precisely, the last password entered), you can use

$FmtPV['$AuthPw'] = 'reset(array_keys((array)@$_SESSION["authpw"]))';
