Magento – Get only the page path of the URL

Try this :

<?php echo $magentoCurrentUrl = Mage::helper('core/url')->getCurrentUrl();?>

If the url is determined by a controller and an action you can use this:

{{store url="module/controller/action"}}

If the url is to a cms page you this:

{{store _direct="url-key-here"}}

if you want some query params also like /some-ulr?a=2&b=5 use one of the methods above and add a _query parameter.

{{store url="module/controller/action" _query="a=2&b=5"}}
{{store _direct="url-key-here" _query="a=2&b=5"}}

[EDIT]
You can get the same urls in a template file like this:

$this->getUrl('module/controller/action'); //for controller pages
$this->getUrl('', array('_direct'=>'some-url-key')); //for cms pages
$this->getUrl('module/controller/action', array('_query'=>'a=2&b=5')); //for query params
$this->getUrl('', array('_direct'=>'some-url-key', '_query'=>'a=2&b=5')); //for query params
