Trying to ad a option to article creation, but page renders either blank or "original

[Vaupell]

Trying to add some options to the options on the right side on the page
where you create articles.. usually i would just use hook, but theres none.

so trying via the cache..

I tryed using the classic str_replace which usually works,
but suspecting its becourse the template i was adding to is
working as a variable..
but then the options panel just renders blank...

Now i tryed craeting a "replica" menu and want to add it above the
publishing options, created a template and trying to render it,
but nada, it does not show.. .

plugin i use to change with
Hook location : process_templates_complete

PHP Code:

 $templater = vB_Template::create('excs_article_option');  
 $elock = $templater->render();  
 
 $oldtemplate = $vbulletin->templatecache['vbcms_edit_publisher'];
 
 $newtemplate = null;
 $newtemplate = $elock . '<br />' . $oldtemplate;
 $vbulletin->templatecache['vbcms_edit_publisher'] = $newtemplate; 


basicly the template is just a bunch of div tags,
like the original article publising options..

PHP Code:

<div class="fullwidth editorheader">
 <div class="headerbar">
  enable content share
 </div>
</div> 
<div class="fullwidth blockbody formcontrols">
 <div class="fullwidth" >
  <div class="thirdleft">Enabel export ? </div>
  <div class="twothirdsright">
   <input type="radio" value="1" name="eviexport" tabindex="1" />{vb:rawphrase yes}&nbsp;&nbsp;
   <input type="radio" value="0" name="eviexport" tabindex="1" checked="checked" />{vb:rawphrase no}
  </div>
 </div>
 
</div>
<div style="clear:both"></div>
