Just create a folder in your lib/plugins dir, called “wikisign”. In it, create a file called action.php containing the following code:

wikisign/action.php

<?php
 
if(!defined('DOKU_INC')) die();
if(!defined('DOKU_PLUGIN')) define('DOKU_PLUGIN',DOKU_INC.'lib/plugins/');
require_once(DOKU_PLUGIN.'action.php');
require_once(DOKU_INC.'inc/common.php');
 
class action_plugin_wikisign extends DokuWiki_Action_Plugin {
    function getInfo() {
        return array (
            'author' => 'FeepingCreature',
            'email' => 'default_357-line@yahoo.de',
            'date' => '2008-11-08',
            'name' => 'WP-style signature',
            'desc' => 'Translate ~~~~ into signature info',
            'url' => ''
        );
    }
    function register(Doku_Event_Handler $controller) {
      $controller->register_hook('IO_WIKIPAGE_WRITE', 'BEFORE', $this, 'signtranslate');
    }
 
    function signtranslate(&$event, $param) {
      $pi = pageinfo();
      global $USERINFO;
      $userinfo = $USERINFO['name'];
      if (empty($userinfo)) $userinfo = $_SERVER[REMOTE_ADDR];
      $date = gmdate('H:i, d F Y e');
      // $event->data[0][1] = str_replace('~~~~', '---//'.$userinfo.' '.$date.'//', $event->data[0][1]);
      // thanks to mystore for the next line (ignore ~~~~ in unparsed blocks)
      $event->data[0][1] = preg_replace('#[^(<nowiki>|<code>|<file>|  |%%)]~~~~#', '---//'.$userinfo.' '.$date.'//', $event->data[0][1]);
    }
}
?>

Have fun!

Add compatibility with non-parsed block : Replace the last line by :

$event->data[0][1] = preg_replace('#[^(<nowiki>|<code>|<file>|  |%%)]~~~~#', '---//'.$userinfo.' '.$date.'//', $event->data[0][1]);

At least give an example of its use. ~~~~ (DOES NOT WORK!)

Strange. That's how it's SUPPOSED to work, and _does_ work here. Are you sure you installed it correctly?

Agree with the person above me. Does not parse at all (even after adding the closing PHP tag at the end), and just shows ~~~~.

Mine gives me the username and date, but adds a weird character after the date. example: —Admin 15:21, 12 December 2008 e

Your PHP's gmdate does not parse the “e” code correctly.
> $date = gmdate('H:i, d F Y e');
Remove the “e” from that line.

I tried putting #~~~~#, it kind of works. but it leaves a trailing #

Ok, same poster as above line. I've modified the last line to…

$event->data[0][1] = preg_replace('/[ \t]+[^(<nowiki>|<code>|<file>|%%)]~~~~ *$/x', '---//'.$userinfo.' '.$date.'//', $event->data[0][1]);

Give it a shot –johncruise

This line works in Hrun. Thank you for the mod.a — KaiMartin 2015-02-27 19:18

This line produces the desired signature in hrun. However, the plugin breaks the download of images. Images cached in the browser still rendered fine in my set-up (Dokuwiki hrun, firefox 31.5). But new images were not displayed. Seems like there is a major conflict which makes the plugin unusable in its current state. — KaiMartin 2015-03-12 01:44

How can I change the code to insert a link to the user-page? like … Admin instead of “Admin”
