Magento – Use a helper in a layout

helperlayoutmagento-1

I want to call a helper in the main layout of my website.

I added this within the part of the layout :

<action method="addLink" translate="label title">
    <label>About us</label>
    <url helper="myModule/getAboutUsUrl" />
    <title>About us</title> 
</action>

And defined my module in the /etc/config.xml this way :

<helpers>
    <myModule>
        <class>My_Module_Helper</class>
    </myModule>
</helpers>

I created my helper My_Module_Helper_Data at the root of includes/src/.

There is no error raised, but it seems that it doesn't work. Any ideas ?

Why are you putting helper file under include/src folder? It should be under your module Helper folder.

Have you enabled compilation mode? If yes then disable that first.

Make a helper class under your module folder and that position should be: YourModuleNameSpace/ModuleName/Helper/Data.php

Class name should be: YourModuleNameSpace_ModuleName_Helper_Data

Then write your function under this class.

Magento – Magento module Invalid block type

You have call all the block types by block prefix mynamespace_mymodule

But you have define it as Mynamespace_Mymodule

 <blocks>
            <Mynamespace_Mymodule> <!-- call as block prefix -->
                <class>Mynamespace_Mymodule_Block</class>
            </Mynamespace_Mymodule>
        </blocks>

You need to change the block prefix Mynamespace_Mymodule by mynamespace_mymodule

<config>
    ...
    <global>
        <blocks>
            <mynamespace_mymodule>
                <class>Mynamespace_Mymodule_Block</class>
            </mynamespace_mymodule>
        </blocks>

Magento – How to set Block’s template by calling a helper from layout XML

xml file

<block type="core/template" name="order_totals_wrapper" as="order_totals" template="email/order/totals/wrapper.phtml">
    <block type="sales/order_totals" name="order_totals">

Extend sales/order_totals block and add the following

protected function _construct()
{
    parent::_construct();
    $this->setTemplate(Mage::helper('Emailbygroup')->getOrderEmailTotalsTemplate());
}

The other way to do this without extending the block is on the xml file,

<block type="core/template" name="order_totals_wrapper" as="order_totals" template="email/order/totals/wrapper.phtml">
    <block type="sales/order_totals" name="order_totals">
        <action method="setTemplate"><template helper="Emailbygroup/Data/getOrderEmailTotalsTemplate"></template></action>
