Open new page via plugin

[Szdnez]

Hello,

I want to write my own OJS plugin. The plugin should put a new link in the list of the journal manager and when I click the link, I want to show a new page. The link is not the problem but I am not able to show a new page. Whatever I have tried, the page is always "empty". That is my code:

index.php

Code: Select all

require( 'VgWortZaehlmarkePlugin.inc.php' );
return new VgWortZaehlmarkePlugin();

VgWortZaehlmarkePlugin.inc.php

Code: Select all

import('classes.plugins.GenericPlugin');

class VgWortZaehlmarkePlugin
extends GenericPlugin
{
   function register( $category, $path )
   {
      if ( parent::register( $category, $path ) )
      {
         HookRegistry::register( 'Templates::Manager::Index::ManagementPages', array( &$this, 'callback' ) );
         $this->addLocaleData();
         
         return true;
      }
      
      return false;
   }
   ...
   function callback( $hookName, $args )
   {
      $params =& $args[0];
      $smarty =& $args[1];
      $output =& $args[2];
      $output .= '<li>&#187; <a href="' . Request::url( null, 'VgWortZaehlmarke' ) . '">' . Locale::translate( 'plugins.generic.vgwortzaehlmarke.linkname' ) . '</a></li>';
        
      return false;
   }
}

VgWortZaehlmarkeHandler.inc.php

Code: Select all

class VgWortZaehlmarkeHandler
extends Handler
{
   function index()
   {
      $templateManager =& TemplateManager::getManager();
      $templateManager->display($plugin->getTemplatePath() . 'VgWortZaehlmarke.tpl');
   }
}

VgWortZaehlmarke.tpl

Code: Select all

<p>Test</p>

Do I hve to register something more, or...? It is nearly the same code as e.g. the counter plugin of OJS. I have no more ideas and I can not debug my code because of OJS development under eclipse with pdt.

Thanks a lot!

At least I had the right "idea". I forgot to register the handler in the plugin. The extended code of VgWortZaehlmarkePlugin.inc.php

Code: Select all

function register( $category, $path )
   {
      if ( parent::register( $category, $path ) )
      {
         HookRegistry::register( 'Templates::Manager::Index::ManagementPages', array( &$this, 'callback' ) );
         HookRegistry::register( 'LoadHandler', array( &$this, 'handleRequest' ) );
         
         $this->addLocaleData();
         
         return true;
      }
      
      return false;
   }
   ...
   function handleRequest( $hookName, $args )
   {
      $page =& $args[0];
      $op =& $args[1];
      $sourceFile =& $args[2];

      if ( $page === 'VgWortZaehlmarke' )
      {
         $this->addLocaleData();
         $this->import( 'VgWortZaehlmarkeHandler' );
         Registry::set( 'VgWortZaehlmarkePlugIn', $this );
         define( 'HANDLER_CLASS', 'VgWortZaehlmarkeHandler' );
         
         return true;
      }

      return false;
   }

Hi,

Actually, I am also interesed in a VG Wort Zählmarke - Plugin.
Is there any way that you could make it available to the public?
Or could you let me know if you could get it working properly?

Best wishes,
Steff
