Help with Generic Plugin and templates

[juli]

Hi all!

I'm working i a new generic plugin to display the issues archive in a list inside the journal index (first page).

I would like to make a plugin to insert a code after the main content and before the footer. I have show in the templates/index/journal.tpl some variables like additionaHomeContent, but I cannot set a value to it. Also I tryed to copy the code of announcementFeed and piwik module to get similar working but I haven't any result.

I think that I must use a Hook but I not understand wichone, the Template::manager::... and templateManager::... seems to be appropiate but no one works for me.

Also the technical reference examples and hook list not solves this problem.

Please, any help will be great.

thanks a lot

Hi Juli,

You probably just need to register the plugin with the system; see e.g. http://pkp.sfu.ca/support/forum/viewtopic.php?f=9&t=7909#p30755.

Hi Alec,

thanks a lot for your fast reply. I have tryed with the

Code: Select all

php tools/upgrade.php upgrade

And also I have cleaned the data and template cache. Any more ideas?

this is my code:

Code: Select all

import('lib.pkp.classes.plugins.GenericPlugin');

class IssueCarouselPlugin extends GenericPlugin {
  function register($category, $path) {
    if (parent::register($category, $path)) {
      if ($this->getEnabled()) {
        HookRegistry::register('TemplateManager::display',array(&$this, 'callbackAddLinks'));
      }
      return true;
    }
    return false;
  }

  function getDisplayName() {
    return Locale::translate('plugins.generic.issuecarousel.displayName');
  }
  function getDescription() {
    return Locale::translate('plugins.generic.issuecarousel.description');
  }
  function callbackAddLinks($hookName, $args) {
    if ($this->getEnabled()) {
      $templateManager =& $args[0];
      $requestedPage = Request::getRequestedPage();

      // if we have a journal selected, append feed meta-links into the header
      $additionalHeadData = $templateManager->get_template_vars('additionalHomeContent');
      $templateManager->assign('additionalHomeContent', $additionalHomeData."\n\t TEST");
    }
    return false;
  }
}


Any help will be realy useful. Thanks a lot.

Hi Juli,

I would suggest using "die()" calls to test whether certain parts of your code are getting called. For example, is the "register" function getting called? Is the hook getting registered? Is the callback getting called?

Hi folks,

My error was that I forgot the version.xml file. I added it, called upgrade (php tools/upgrade.php upgrade), clear caches and get it working.

thanks a lot, when I finis I will release it!
