# Layout Variables

Variable substitutions in the skin template are all managed by the FmtPageName() function from pmwiki.php. Pmwiki variable substitutions available on pages are managed by the substitutions from stdmarkup.php or superseded in local/config files.

$WikiTitle A variable which contains the Wiki title as displayed by the browser $HTMLStylesFmt
An array of CSS statements to be included in the page's output along with other HTML headers. This array provides an easy place for scripts to add custom CSS statements.
$HTMLHeaderFmt An array of HTML text to be included in the page's <head> section, at the point where the skin template specifies a <!--HTMLHeader--> directive. This array provides an easy place for scripts to add custom HTML headers. For example, if you want to specify a logo for all the pages of your wiki (a png image for Firefox (and others...), an ico for Internet Explorer): $HTMLHeaderFmt['logo'] =
<link href="http://your/wiki/path/to/your/logo/logo.ico" type="image/x-icon" rel="shortcut icon" />';

Another example, if you want to get the rss notification on some browsers (the rss icon in firefox for instance):

$HTMLHeaderFmt['rss'] = '<link rel="alternate" type="application/rss+xml" title="Rss All recent Changes" href="$ScriptUrl/Site/AllRecentChanges?action=rss" />';

$HTMLFooterFmt Like $HTMLHeaderFmt above, this contains an array of HTML text to be included near the end of an HTML document, at the point where the skin template specifies a <!--HTMLFooter--> directive (usually just before a closing </body> tag). Primarily used by scripts to add custom HTML output after the body of the page output.
$MetaRobots Sets the value of the <meta name='robots' ... /> tag generated by Pm Wiki to control search engine robots accessing the site. Pm Wiki's default setting tells robots to not index anything but the normal page view, and to not index pages in the Pm Wiki wiki group. Explicitly setting $MetaRobots overrides this default.
        # never index this site
$MetaRobots = 'noindex,nofollow'; # disable the robots tag entirely $MetaRobots = '';

$MessagesFmt An array of HTML text to be displayed at the point of any (:messages:) markup. Commonly used for displaying messages with respect to editing pages. $RecentChangesFmt
An array specifying the format of the listing.
The format can be specified in your config.php using the following:
$RecentChangesFmt['$SiteGroup.AllRecentChanges'] =
'* [[$Group.$Name]] . . . $CurrentTime$[by] $AuthorLink: [=$ChangeSummary=]=][=';
$RecentChangesFmt['$Group.RecentChanges'] =
'* [[$Group/$Name]] . . . $CurrentTime$[by] $AuthorLink: [=$ChangeSummary=]=][=';

Note that changes made to the format will only affect new edits. In other words, you will need to edit a page for your new format to be visible. Note also that you need to have two spaces between the page name and the other information about the edit.
$RCLinesMax The maximum number of lines to be stored in pages. The default is zero, meaning "no limit".  $RCLinesMax = 1000;       # maintain at most 1000 recent changes

$PageRedirectFmt The text to be used when a page is redirected via the (:redirect:) markup. $PageRedirectFmt = '<p><i>redirected from $FullName</p>';$PageRedirectFmt = '';

$WikiStyle An array which contains the predefined Wiki Styles which can be used on a textpage. See: PmWiki.CustomWikiStyles $MaxIncludes
Controls the number of times that pages can be included via the (:include:) and other directives, used to control recursion and otherwise pose a sanity check on page contents. $MaxIncludes defaults to 50, but can be set to any value by the wiki administrator.  $MaxIncludes = 50;            # default
$MaxIncludes = 1000; # allow lots of includes $MaxIncludes = 0;             # turn off includes

$Skin Points to the directory of an own or different layout skin. $SkinDirUrl
Set by scripts/skins.php to be the base url of the current skin's directory (i.e., within a 'pub/skins/' directory). This variable is typically used inside of a skin .tmpl file to provide access to .css files and graphic images associated with the skin.
$SkinLibDirs An array that specifies the filesystem and url locations to use to find skins. $PageLogoUrl
is the url that refers to a logo image which most skins display somewhere in the page's header (top left usually).
$EnablePathInfo Changes the handling of the page URL. When set to 1 page URL will be ...wiki.php/Main/Main, when set to 0 (default) it will be ...wiki.php?n=Main.Main. $EnableFixedUrlRedirect
When Pm Wiki is given a partial page name (e.g., just the name of a Wiki Group), it uses $PagePathFmt in order to make a complete page name from the partial one, then issues a "redirect" to the browser to tell it to reload the page with the correct full page name. Setting $EnableFixedUrlRedirect=0; blocks the redirect, so that Pm Wiki continues processing with the adjusted page name rather than issuing the redirect.
$GroupHeaderFmt Defines the markup placed at the top of every page. Default value is:  $GroupHeaderFmt = '(:include $Group.GroupHeader:)(:nl:)';  $GroupFooterFmt
Defines the markup placed at the bottom of every page. Default value is:
        $GroupFooterFmt = '(:include$Group.GroupFooter:)(:nl:)';

$PageNotFoundHeaderFmt Specifies the HTTP header to send when attempting to browse a page that doesn't exist. Some webserver packages (notably Microsoft's "Personal Web Server") require that this variable be changed in order to work. # default$PageNotFoundHeaderFmt = 'HTTP/1.1 404 Not Found';
# return all pages as found
$PageNotFoundHeaderFmt = 'HTTP/1.1 200 Ok';  $HTMLVSpace
Setting $HTMLVSpace = ''; in a local customizationfile (e.g., local/config.php) prevents insertion of spacer paragraphs (<p class='vspace'></p>) in generated HTML code. To limit this change to a single skin, place the $HTMLVSpace = ''; statement in a skin.php file, preceded by the statement global $HTMLVSpace;. $TableCellAttrFmt
For Tables, defines the HTML attributes given to each <td> or <th> cell in the output. Can contain references to $TableCellCount which holds the horizontal column number of the current cell. $TableRowAttrFmt
For Tables, defines the HTML attributes given to each <tr> element in the output. Can contain references to $TableRowCount to give the absolute row number within the table, or$TableRowIndex to provide a repeating row index from 1 to $TableRowIndexMax.  # Give each row a unique CSS class based on row number (tr1, tr2, tr3, ... ) $TableRowAttrFmt = "class='tr\$TableRowCount'"; # Give each row alternating CSS classes (ti1, ti2, ti1, ti2, ti1, ... ) $TableRowIndexMax = 2;
$TableRowAttrFmt = "class='ti\$TableRowIndex'";

$TableRowIndexMax The maximum value for$TableRowIndex in Tables.
        # Set rows indexes as 1, 2, 3, 1, 2, 3, 1, 2, ...
\$TableRowIndexMax = 3;
