Syntax

Basic syntax:

{{actionlink>[action]|[title]}}

Where action can be one of this (after inc/template.php):

  • edit - edit/create/show
  • history - old revisions
  • recent - recent changes
  • login - login/logout - if ACL enabled
  • index - the index
  • admin - admin page - if enough rights
  • top - a 'back to top' link
  • back - a 'back to parent' link - if available
  • backlink - list of backlinks


The title element is optional. It lets you specify a custom string to be used instead of the default 'Edit this page', 'Old revisions', 'Recent changes', etc.

Examples

For example, syntax like this:

You can easily {{actionlink>edit|customise}} this page.

Will produce an output like this: 'You can easily customise this page', where 'customise' is a link to the 'Edit page' page.

Syntax like this:

{{actionlink>edit}}

Will simply create a 'Edit this page' link.

Installation

You can install this plugin using the plugin manager.

Discussion

This is my first DokuWiki plugin ever, so please, be gentle ;-)nowotny 2006-05-26

Wouldn't it be easier to call tpl_actionlink and capture the output?
e.g.
ob_start();
tpl_actionlink(...);
$renderer->doc .= ob_get_clean();

Christopher Smith 2006-05-26 15:54

Probably… but you wouldn't be able to change the 'title'(caption…? whatever you call it… :-) ). — nowotny 2006-05-26 19:17
Fair enough. There are a couple of ways you could do it, but point taken. :-)Christopher Smith 2006-05-28 14:28

You can (now? or always possible?) set the linktext via the tpl_actionlink-function. Exchange the following code with the original render-function an you benefit to all changes in the tpl_actionlink function

function render($mode, &$renderer, $data)
{
  if($mode == 'xhtml')
  {
    if(!empty($data['title'])) $title=$data['title'];
    if(!empty($data['action']))
    {
      $action=$data['action'];
    }
    else
    {
      if(!isset($title)) $title='';
      $renderer->doc .= $title;
      return true;
    }
    if(isset($title))
    {
      ob_start();
      tpl_actionlink($action,'','',$title);
      $renderer->doc .= ob_get_clean();
    }
    else
    {
      ob_start();
      tpl_actionlink($action);
      $renderer->doc .= ob_get_clean();
    }
    return true;
  }
  return false;
}

I'm new to all this, but what would the syntax be when changing the tpl_actionlink function code? — Randy 2008-12-14
The feed.php page returns a missing function error unless inc/template.php is included at the top of the plugin code, otherwise, great little plugin. Thanks!

Not sure if this plugin is still maintained but is it possible to add a manual link to the search function in this plugin too?

Purge

to add purge, I put following in front of the “default:” fallback:

                        case 'purge':
                                if(!isset($title)) $title=$lang['btn_purge'];
                                $renderer->doc .=$this->tpll_link(wl($ID,'purge=true'),$title, 'class="action purge"');
                                return true;

Problem with recent changes

I got a small problem with actionlink>recent (with httaccess rewrite) : it keeps the current page in the URL, resulting in a partial recent changes (it is limited to the current namespace). E.g. on the page http://mydokuwiki.com/namespace/page, {{actionlink>recent}} points to http://mydokuwiki.com/namespace/page?do=recent, which show recent changes only for the namespace namespace. This also cause the actionlink>index to unwrap the current namespace, but this is less of a problem.
– Fousage

Will this become fixed? Dakkar

This situation happens to me as well. I don't want to change the code, but do you have any solution for this? Something like this would be great: {{actionlink>:recent|Recent Changes}} in this way, we could use the actions for the namespaces. – Luis Nabais
Is there any way to implement subscription link with this plugin?. Thanks.
Manuel Munoz

Insert this code into the function “render” :

case 'subscribe':
  if(!isset($title)) $title=$lang['btn_subscribe'];
  $renderer->doc .=$this->tpll_link(wl($ID, array("do"=>"subscribe"), false, "&"),$title,'class="action subscribe"');
  return true;

SandyANF

use NOCACHE

When builing actionlinks for 'admin', 'login' etc. dont forget

~~NOCACHE~~

otherwise (ha!) the page will be cached with authentication infos of the last user editing the page.

Maybe other actions depend on not being cached too…
