magento 전역 변수 또는 함수 설정(Session, Registry 및 Function)

1. Magento: Get and set variables in session
 
To set a Magento session variable:
$myValue = 'Hello World';
Mage::getSingleton('core/session')->setMyValue($myValue);
 
To Retrieve:
$myValue = '';
$myValue=Mage::getSingleton('core/session')->getMyValue();

 
To Unset:
Mage::getSingleton('core/session')->unsMyValue();

 
혹은
/* Core Session */ 
Mage::getSingleton('core/session')->setYourVariable('data');
$Data = Mage::getSingleton('core/session')->getYourVariable();
 
/* Customer Session */ 
Mage::getSingleton('customer/session')->setYourVariable('data');
$Data = Mage::getSingleton('customer/session')->getYourVariable();
 
/* Admin Session */ 
Mage::getSingleton('admin/session')->setYourVariable('data');
$Data = Mage::getSingleton('admin/session')->getYourVariable();

 
2. Magento’s Registry Pattern
 
The three registry methods are
Mage::register
Mage::unregister   
Mage::registry    
 
The register method is how you set a global-like variable.
Mage::register('some_name', $var);
 
Then, later in the request execution, (from any method), you can fetch your variable back out
$my_var = Mage::registry('some_name');

 
Finally, if you want to make you variable unavailable, you can use the unregister method to remove it from the registry.
Mage::unregister('some_name');

3.  Create Global Function In Magento
 
This code will allow you to add a function that can be called from anywhere within Magento. It extends the helper class
 
1) Create a file named ‘Mycode.xml’ and copy it to app/etc/modules/– it should look like this:
<?xml version="1.0"?>
<config>
    <modules>
		<Mycode_Function>
			<active>true</active>
			<codePool>local</codePool>
		</Mycode_Function>
    </modules>
</config>
 
2) Create the directory app/code/local/Mycode/Function/etc and then create a file named ‘config.xml’ In it copy:
<?xml version="1.0"?>
<config>
 
    <modules>
        <Mycode_Function>
            <version>1.0.0</version>
        </Mycode_Function>
    </modules>
 
    <global>
 
        <helpers>
            <function>
                <class>Mycode_Function_Helper</class>
            </function>
        </helpers> 
 
    </global>
 
</config>
 
3) Create the directory app/code/local/Mycode/Function/Helper and then create a file named ‘Data.php’ In it copy:
<?php
 
class Mycode_Function_Helper_Data extends Mage_Core_Helper_Abstract
{
 
	public function test(){
 
	return 'works';
 
	}
 
}
 
You can now call this function like so
<?php 
 
	 echo Mage::helper('function')->test();
 
 ?>
