Edit Variables

<< Link Variables | Variables | (Upload Variables)? >>

The variables listed on this page affect editing and saving of text to pages.

$DefaultPageTextFmt: The text that should be displayed when editing or browsing non-existent pages. May also appear in other contexts, such as when a non-existent page is included via [[include:PageName]].

        $DefaultPageTextFmt = 'Page $Tlink does not exist';

$DiffKeepDays: The minimum number of days to keep a page's revision history. Defaults to 3650 (a little less than ten years).
$DeleteKeyWord: The string that indicates a page should be deleted. Defaults to 'delete'.
$SysDiffCmd: The path to an external program that performs the equivalent of GNU's diff(1) program for maintaining Page History. Defaults to /usr/bin/diff, but may need to be changed on systems where diff(1) is in a different location (e.g., when running on Windows servers) or is encumbered by (PHP Safe Mode)?. Setting this to an empty string disables Page History.

        $SysDiffCmd='/usr/bin/diff';      # default
        $SysDiffCmd='';                   # disable page history
        # The following is used by Win Diff
        $SysDiffCmd='windiff\\diff';
        # Sometimes a workaround for (PHP Safe Mode)?
        $SysDiffCmd='./diff';

$SysPatchCmd: The path to an external program that performs the equivalent of GNU's patch(1) program for merging diff's. Defaults to "/usr/bin/patch --silent", but may need to be changed on systems where patch(1) is somewhere else. Setting this to an empty string disables the "Restore" feature of Page History.

        $SysPatchCmd = '';                # disable restore
        # The following is used by Win Diff
        $SysPatchCmd='windiff\\patch --silent';

$DiffFunction
$PatchFunction
: The names of the PHP functions to be called to generate/restore page history information. Defaults to Pm Wiki's internal "Diff" and "Patch" functions, but these can be changed to allow a user to create customized diff/patch capabilities. This is used by the (Cookbook.PHP Diff Engine)?.
$RecentChanges: An array containing the page names and text format lines to be used to save Recent Changes information.
$EnablePostAuthorRequired: If set to a non-zero value, then authors are required to provide a name in the "Author" field of the edit form before changes may be saved to a page.
$AuthorRequiredFmt: The message displayed above the edit form when $EnablePostAuthorRequired is set and an author has failed to provide a name in the "Author" field.
