zend framework - Enable jQuery using with ZendX_JQuery in a view helper -

-

i trying activate jquery through view helper called within layout.

the problem jquery called within layout , renders include files, before defined in view helper.

here scripts :

layout.phtml:

<?php echo $this->doctype(); ?> <html> <head>     <?php echo $this->headtitle() ?>     <?php echo $this->headlink()->appendstylesheet('/css/base.css') ?>     <?php echo $this->headmeta() ?>     <?php echo $this->headstyle() ?>     <?php echo $this->jquery() ?>  </head> <body> [...]     <div id="droite" class="column grid_4">         <!-- column 2 start -->         <?php echo $this->render('partials/droite.phtml'); ?>         <!-- column 2 end -->     </div> </body> </html>

partials/droite.phtml:

<?=$this->rolelinks(); ?>

my_view_helper_rolelinks:

<?php  class my_view_helper_rolelinks extends zend_view_helper_abstract {      public function rolelinks()     {         if (model_user::hasidentity()) {             $role = model_user::getrole();             if ($role === 'admin') {                 return $this->view->partial('partials/droite_admin.phtml');                 return;             }         } else {             return '';         }     } }

partials/droite_admin.phtml:

<?php $this->jquery()     ->uienable()     ->addjavascriptfile('/js/jquery.ui.datepicker-fr.js')     ->addjavascriptfile('/js/onload.js'); ?>  <div id="calendar"></div>

so.

not sure right way it, main idea check if user admin enable jquery , display datepicker (calendar).

thanks in advance help.

you try check if jquery enabled in layout avoid double inclusion.

<head>     <?php echo $this->headtitle() ?>     <?php echo $this->headlink()->appendstylesheet('/css/base.css') ?>     <?php echo $this->headmeta() ?>     <?php echo $this->headstyle() ?>      <?php if (! $this->jquery()->isenabled()) {         echo $this->jquery();      } ?> </head>

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
