DokuWiki

Two corrections are needed in action.php to make this old plugin work again:

1. on line 38 replace
   function register(&$contr)
   by
   function register(Doku_Event_Handler $contr)
2. on line 42 replace
   function _display_message(&$event, $param) {
   by
   function _display_message(Doku_Event $event, $param) {

Also you can add this free plugin's SVG-icon for admin panel to the plugin's root. Don't forget to check the content, there 585 bytes of normal SVG-code

• action: displays the message(s) contained into the message_error.txt, message_info.txt, message_valid.txt and message_remind.txt files stored under the data/cache folder.
• The messages appear on every page, for all users.

• 2008-10-07: first one!
• 2009-03-11: manage the messages in the admin section.
• 2009-08-04: The txt messages files are now stored in $conf['cachedir'] (and no more in the plugin folder. Thanks to Christophe M). Improved compatibility of the admin screen with templates.

• It says above that the message files are named e.g. error.txt, shouldn't it say e.g. message_error.txt ?
• Tell me…
  • It would be great to know where to put this in the DokuWiki directory structure. Sorry, I have a problem with the plugin manager not installing this plugin correctly.
    • Zip up the plugin directory and any children, but no parents. Take a look at some other plugin packages to see how they are done. — Christopher Smith 2009/01/21 09:39
  • It would be great to be able to manage these messages in the admin section. Not very friendly to edit the text file directly. Especially remotely. — Alexandre Fremion 2009/02/23 18:36
    • This will be possible in a upcoming new version. — Etienne M. 2009/03/09 14:12

It would be nice to make the messages dismissable. Perhaps a checkbox besides each message in the admin section to toggle this function on/off. I personally see many use cases for this, but realise it is a long shot, considering that the developer hasn't updated his plugins in several years. Anyways, I am still happy with the plugin as it is now. Thanks! — Eivind 2016-01-09 16:35

While I'm at it, why not ask for time based messages as well? For instance, I'd like a message to appear only on a set date, and disappear the following day. I'm not expecting recurring messages, as that would likely be grounds for a new plugin, just the possibility to set a start and end time for each message. — Eivind 2016-01-09 16:44

To prevent these messages from showing up when not logged in, modify the _display_message function in action.php:

    function _display_message(&$event, $param) {
        global $conf;
        global $ID;
        $perm = auth_quickaclcheck($ID);
            if($perm > AUTH_NONE){

                $file=$conf['cachedir'].'/message_error.txt';
                if (file_exists($file) && filesize($file)) msg(@file_get_contents($file),-1);

                $file=$conf['cachedir'].'/message_info.txt';
                if (file_exists($file) && filesize($file)) msg(@file_get_contents($file),0);

                $file=$conf['cachedir'].'/message_valid.txt';
                if (file_exists($file) && filesize($file)) msg(@file_get_contents($file),1);

                $file=$conf['cachedir'].'/message_remind.txt';
                if (file_exists($file) && filesize($file)) msg(@file_get_contents($file),2);
                
            }
        return;

It would be nice to introduce language divised notes for sites with multilanguage support.

Save this as %your_domain%/lib/plugins/message/admin.svg and look at %your_domain%/doku.php?do=admin. Freeware.
