plugin insert javascript in header

Postby MarieNyst » Thu Dec 13, 2012 10:06 am

Hi !

I would like to insert javascript in header. For this, I've my register function here :

Code: Select all
function register($category, $path) {
        if (parent::register($category, $path)) {
            $this->addLocaleData();
              if ($this->getEnabled()) {
                // Insert header on every header (callback function checks if it addition is really need)
                HookRegistry::register('TemplateManager::display',array(&$this, 'callback'));
            }
            return true;
        }
        return false;
    }


and my callback function here :

Code: Select all
function callback($hookName, $args) {
       
      //First argument is a TemplateManager object.
        $templateMgr =& $args[0];

        //Getting some context.
        $journal = &Request::getJournal();
        $journalId = $journal->getJournalId();
        $page = Request::getRequestedPage();
        $op = Request::getRequestedOp();
        $currentJournal = $templateMgr->get_template_vars('currentJournal');

        //Add additionalHeader just in a few pages of the current Journal:
        if (!empty($currentJournal))
      {
         //Extending template's head:
            $additionalHeadData = $templateMgr->get_template_vars('additionalHeadData');
            $additionalHeadData .= "\n\n        <!-- Keywords Headers -->\n";
            $additionalHeadData .= $templateMgr->fetch('./plugins/generic/keywords/generatedFiles/keywordsChoiceScript.js.tpl');
            $additionalHeadData .= "        <!-- Keywords Headers -->";

            $templateMgr->assign('additionalHeadData', $additionalHeadData);
      }
      
        return false;
    }


and my script here :

Code: Select all
{literal}<script type="text/javascript" src="http://code.jquery.com/jquery-latest.pack.js"></script>
<style>
 a {color:#333; text-decoration:none}
 a:hover {color:#ccc; text-decoration:none}

   <!-- style doesn't mater -->
   </style>
<script>
   function keywordsSetOptions(chosen) {
<!-- script that I've already tested-->
      }
$(document).ready(function() {
 
    <!-- some other things I've tested -->
     
});
</script>{/literal}


Nothing happens, my headers are still the same... Did I make it wrong ?

Hi MarieNyst,

You probably need to register the plugin in the database; have a look at http://pkp.sfu.ca/support/forum/viewtopic.php?f=9&t=7909#p30755 or http://pkp.sfu.ca/support/forum/viewtopic.php?f=9&t=9067#p35235 for some further discussion. There is also some howto documentation at http://pkp.sfu.ca/wiki/index.php/Writing_a_Block_Plugin.
