Trigger event on Zend Framework 2 view/layout - events

There is any way to trigger an event like wordpress on views/layouts? What i need is something like this:
index.phtml:
<?php $this->triggerEvent('before_navigation', $params, $order); ?>
<?php echo $this->navigation('navigation')->menu() ?>
<?php $this->triggerEvent('after_navigation', $params, $order); ?>
Then, any module can be capable to attach a listener with the name of the event and do what the want sorted by $order

codeigniter - Flashdata not clearing

i'm new with codeigniter and use flashdata to display message from controller to view. However, flashdata is not cleared automatically after i refresh the view or move to the other pages and back it still remain. Please help.
Here is my code in controller:
$this->session->set_flashdata('_flash_message', 'Thanks for your subscription.');
redirect(site_url('cp/subscribe'), 'refresh');
In view:
<?php echo $this->session->flashdata('_flash_message'); ?>
I used XAMPP for localhost, already turn off cache mode.
Try
On Controller
$this->session->set_flashdata('flash_message', 'Thanks for your subscription.');
redirect(base_url('cp/subscribe'));
On View
<?php if ($this->session->flashdata('flash_message') {
<?php echo $this->session->flashdata('flash_message');?>
<?php }?>
In the view you need to add an if statement to check if the flashdata is set. When refreshing the browser it will not be set so the message will not reappear.
<?php if($this->session->flashdata('_flash_message')) : ?>
<?php echo '<p>' .$this->session->flashdata('_flash_message'). '</p>'; ?>
<?php endif; ?>

Populate custom attributes from database Magento

I needed to add a custom attribute to categories on Magento, I have been able to do so using:
http://www.atwix.com/magento/add-category-attribute/
But now, I will like to turn the custom attribute into a select box and load the options from a external database/module. Is there any way to specificy the options available for the custom attribute in order to make them dinamic?
Thanks.
Have you found the solution? I'm doing it in phtml file like this
<?php $categories = Mage::getModel('catalog/category')->getCollection()->addAttributeToSelect('*'); ?>
<?php foreach ($categories as $category): ?>
<?php $customAtt= $category->getCustom_att(); ?>
<?php print_r ($customAtt); ?>
<?php endforeach; ?>
That way will populate all your custom category attribute values. Change the getCustom_att() with your custom attribute.
To make it a select option list, read this https://magento.stackexchange.com/questions/8674/how-to-get-all-custom-category-attribute-values/8692#8692

Magento - Unable to display custom options

I'm using a module for displaying grouped configurable products and all options are showing except custom options. They are displaying on the configurable product page but that's it. I'm trying to use the code in app\design\frontend\blank\blank\template\catalog\product\view\options.phtml in my custom configurable.phtml but $_options is showing up null. Here is the code used to retrieve $_options
<?php $_options = Mage::helper('core')->decorateArray($this->getOptions()) ?>
<?php if (count($_options)):?>
and after the javascript
<?php foreach($_options as $_option): ?>
<?php echo $this->getOptionHtml($_option) ?>
<?php endforeach; ?>
</dl>
<?php else: echo dlkghflghf;?>
<?php endif; ?>
The dlkghflghf is displaying so i know $_options is not showing up. Any suggestions?
Your custom configurable.phtml is a template of what block? You can use a block that extends Mage_Catalog_Block_Product_View_Options or you can set your own method for options like the method from Mage_Catalog_Block_Product_View_Options, you also need to have a method getProduct():
public function getOptions()
{
return $this->getProduct()->getOptions();
}

Best way for creating dynamic sidebar section in Symfony 1.4

I have few frontend modules which has own sidebar menu link. I want to create those links in actions class of module:
public function preExecute()
{
$items['plan/new'] = 'Create Plan';
$items['plan/index'] = 'Plans Listing';
$this->getResponse()->setSlot('sidebar', $items);
}
Slot file sidebar.php
#apps/frontend/templates/sidebar.php
<?php slot('sidebar') ?>
<ul>
<?php foreach($items as $url => $title) : ?>
<li><?php echo link_to($url, $title) ?></li>
<?php endforeach ?>
</ul>
<?php end_slot() ?>
layout.php:
<?php if (has_slot('sidebar')): ?>
<div id="sidebar"><?php include_slot('sidebar') ?></div>
<?php endif ?>
but my output is Array, how can I render my slot?
You seem to be mixing slots and partials. In your action, you set your slot to an array, later you call include_slot, and the string representation is Array, that is correct.
You should pass items via $this->items = $items, then in your action see if isset($items) is true, and call include_partial("sidebar", array("items" => $items)) if neccesary. This will look for a file called _sidebar.php.
For more detailed information of how this stuff works, read the Inside the View Layer: Code fragments part of the sf1.4 book.

MAGENTO getting the descriptions from a sub category

Hi I'm new to magento and have been trying to set up a static block that displays a list of sub categories within a category. I've been succesfull a grabbing the sub-category images and names, but for some reason I can't seem to get the descriptions to show.
Here's the code can't anyone explain why it won't work and how I can fix it?
I've commented out a few lines because I was trying different things to get it to work.
helper('catalog/output');
$category = $this->getCurrentCategory();
getCurrentChildCategories();
?>
<?php foreach ($_categories as $_category): ?> <?php echo
$this->htmlEscape($_category->getCategoryDescription());?>
<?php if($_category->getIsActive()): ?>
<div class="subcategory-image">
<a href="<?php echo $_category->getURL()
?>" title="htmlEscape($_category->getName())
?>">
</a>
<?php /* echo "Find this item->" */ ?>
</div> <div class="sub-category-container">
<h2><a href="<?php echo $_category->getURL()
?>" title="htmlEscape($_category->getName())
?>">htmlEscape($_category->getName())
?>
getURL() ?>"
class="moreLink">[MORE...]
getDescription() ?>-->
getDescription()):
?>
categoryAttribute($_category, $_description, 'description'); ?>
-->
This is one of those cases where Varien decided that they should call "load" on the data collection before returning it when that really isn't necessary and makes the utility function utterly useless.. If you trace the code down for Mage_Catalog_Block_Navigation->getChildrenCategories() you will eventually find this in Mage_Catalog_Model_Resource_Eav_Mysql4_Category:
public function getChildrenCategories($category)
{
$collection = $category->getCollection();
/* #var $collection Mage_Catalog_Model_Resource_Eav_Mysql4_Category_Collection */
$collection->addAttributeToSelect('url_key')
->addAttributeToSelect('name')
->addAttributeToSelect('all_children')
->addAttributeToSelect('is_anchor')
->addAttributeToFilter('is_active', 1)
->addIdFilter($category->getChildren())
->setOrder('position', 'ASC')
->joinUrlRewrite()
->load();
return $collection;
}
The next to last line ->load(); means that the query is executed and the collection is loaded so it is too late to modify the query. So what you will want to do is copy and paste that in place of calling getChildrenCategories and then add the additional attributes you want to use like so:
$_categories = $category->getCollection()
->addAttributeToSelect(
array('url_key','name','all_children','is_anchor','description')
)
->addAttributeToFilter('is_active', 1)
->addIdFilter($category->getChildren())
->setOrder('position', 'ASC')
->joinUrlRewrite()
;
Now the collection will include the description attribute so that getDescription() will work. Notice that you do not need to call load(), it happens automatically when you start using the iterator (the foreach loop triggers this). This is why it is pointless for the load() call to be included in that function because otherwise you could have just added one line below the function call:
$categories->addAttributeToSelect('description');
But instead you have to copy the contents of the function to tweak the query.
Change:
$_category->getCategoryDescription()
To this:
$_category->getDescription()
