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 ("Page Name?") saves changes to a new name ("Page Name?-Draft")
  2. subsequent attempts to edit Page Name? causes Page Name?-Draft to be edited
  3. subsequent selections of "Save draft" cause Page Name?-Draft to be saved
  4. pressing "Publish" causes Page Name?-Draft to be posted to Page Name?, 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.
$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
$DeleteKeyPattern = "^\\s*$";
$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');
See Cookbook:EditTemplates for more information.
$AutoCreate
Used in conjunction with the Auto Create Targets? 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 Pm Wiki uses the contents of Site.Page Not Found
$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 Pm Wiki 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 Recent Changes? 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.Edit Form?'.
$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';
