If you’ve ever needed to fetch header information in Magento, it’s quite a pain. The good news is that Magento gives you some helpers that makes all of it pretty easy. Working with URLs is a topic all of it’s own, but Magento provides a couple of nifty methods in it’s URL helper to help manipulate parameters inside of your URL.
Header Information
These methods are located in Mage_Core_Helper_Http .
|
1 2 3 4 5 6 7 8 9 |
Mage::helper('core/http')->getHttpHost(); Mage::helper('core/http')->getHttpUserAgent(); Mage::helper('core/http')->getRequestUri(); Mage::helper('core/http')->getServerAddr(); Mage::helper('core/http')->getRemoteAddr(); |
URLs
These methods are located in Mage_Core_Helper_Url .
|
1 2 3 4 5 |
Mage::helper('core/url')->getCurrentUrl(); Mage::helper('core/url')->addRequestParam($url, array('id', '25')); Mage::helper('core/url')->removeRequestParam($url, 'id'); |
Always remember, before you go an try creating a method yourself, see if Magento already did it for you. There are some amazing things inside the system and you’ll always be pleasantly surprised by what you will find.
