Edit Variables

To set many of the variables below specify them in config.php.

$EnableGUIButtons When set to '1', turns on the graphical buttons in the "Edit Page" form. # turn on graphical edit buttons $EnablePostAuthorRequired
When set to '1', posting of pages requires the author to provide an author name. Otherwise, authors can post without a name.
# require authors to provide a name
$EnableDrafts When set to '1', enables the "Save draft" button and built-in handling of "draft" versions of pages, where: 1. initial "Save draft" of an existing page ("PageName") saves changes to a new name ("PageName-Draft") 2. subsequent attempts to edit PageName causes PageName-Draft to be edited 3. subsequent selections of "Save draft" cause PageName-Draft to be saved 4. pressing "Publish" causes PageName-Draft to be posted to PageName, and deleted. # turn on draft edits A related variable, $EnablePublishAttr, adds a new "publish" authorization level to distinguish editing of drafts from publishing them.
$DraftSuffix The suffix to use for draft versions of pages (default "-Draft"). $DiffKeepDays
The $DiffKeepDays variable sets the minimum length of time that a page's revision history is kept. By default it is set to 3650 days, or a little less than ten years. You can change this value in a customization file to be something smaller, e.g.: $DiffKeepDays = 30; # keep revisions at least 30 days
Note that a specific page revision isn't removed from the page until the first edit after the time specified by $DiffKeepDays has elapsed. Thus, it's still possible for some pages to have revisions older than $DiffKeepDays -- such revisions will be removed the next time those pages are edited.
$DiffKeepNum This variable contains the minimum number of changes to be kept in the page history, even if some of them are older than the limit defined by $DiffKeepDays. It prevents lost history of pages that are older, but have few changes.
$DiffKeepNum = 50; # keep at least 50 revisions (default is 20) $DeleteKeyPattern
The pattern used to determine if a page should be deleted. The default is to remove pages that contain only the single word "delete" (and optional spaces).
# change delete word to "remove"
$DeleteKeyPattern = "^\\s*remove\\s*$";
# delete any page with no visible text, i.e., empty
$EditTemplatesFmt Name of the page (or an array of names) to be used as the default text for any newly created pages. # Use 'Main.NewPageTemplate' as default text of all new pages$EditTemplatesFmt = 'Main.NewPageTemplate';
# Use 'Template' in the current group for new pages
$EditTemplatesFmt = '$Group.Template';
# Use 'Template' in the current group if it exists, otherwise
# use 'Main.NewPageTemplate'
$EditTemplatesFmt = array('$Group.Template', 'Main.NewPageTemplate');
$AutoCreate Used in conjunction with the AutoCreateTargets edit function, this array records any sets of pages which should be created automatically if they don't exist. The syntax is $AutoCreate[REGEXP] = PAGE_PARAMETERS;
where REGEXP is a regular expression which will identify the pages to be autocreated, and PAGE_PARAMETERS is an array of attributes for the page to be created. For example,
$AutoCreate['/^Category\\./'] = array('ctime' =>$Now);
will create a blank page with a current creation time for any missing Category page.
$DefaultPageTextFmt The text that should be displayed when browsing non-existent pages. As default PmWiki uses the contents of Site.PageNotFound $DefaultPageTextFmt = '(:include $[{$SiteGroup}.PageNotFound]:)';
$EditFunctions This array contains the sequence of functions that are called when a page is edited. It can be customized to provide additional functions to be called as part of the editing process. The standard setting is: $EditFunctions = array('EditTemplate', 'RestorePage', 'ReplaceOnSave',
'SaveAttributes', 'PostPage', 'PostRecentChanges', 'AutoCreateTargets', 'PreviewPage'); 
$ROEPatterns With this array you can add a pattern as key and set a text value which replace it on every edit request, using preg_replace function. Specifically it is replaced when the page is loaded into the editform, whenever a preview is done, and when the page is saved (from PmWiki 2.2.0beta45). See Cookbook:ROEPatterns for examples. $ROSPatterns
With this array you can add patterns as key and set a text value which will replace it when the edited page is posted (as signaled by $EnablePost). It is not replaced when the page is loaded into the editform nor when a preview is done, but it is replaced only when the page is saved. See Cookbook:ROSPatterns for examples. $IsPagePosted
Set to a true value if the page is actually saved (e.g., this is used to tell the RecentChanges handlers if they need to update).
$PageEditFmt By default, this is the HTML to be displayed for an edit form. $PageEditForm
Specifies the edit form for ?action=edit. Defaults to '$SiteGroup.EditForm'. $HandleEditFmt
Like $HandleBrowseFmt, this specifies the entire output format for ?action=edit for a page. $EditRedirectFmt
The page to which an author is sent after pressing "Save" or "Cancel" from an edit form. Defaults to "$FullName", which sends the author to the page just edited, but can be changed to specify another page. # redirect to Main.HomePage$EditRedirectFmt = 'Main.HomePage';
# redirect to HomePage of current group
$EditRedirectFmt = '{$Group}.HomePage';
