Question

I need to pass a parameter to a new page (without query strings), because I would like to redirect back to the module and query string of the current page.

So I can get from

1. showdown/index?id=35 –click—> showdown/vote?id=1
2. showdown/vote?id=1 –redirect–> showdown/index?id=35

The vote action is not seen.

(The redirect method doesn’t work as it redirects to the plain index.php homepage url only and not keeping the module/action intact, and I cannot find a helper in Magento for creating hyperlinks.)

Does Magneto have a link helper for this?

Example of stuff I want: <a href="<?php echo Mage::Helper->Link->($url, $array); ?> then $array or whatever variables gets sent to the controller (page I linked to).

Can I use a POST style hyperlink? (I can in Symfony/Yii/Rails/Ramaze frameworks. Why not Zend?)

Answer 1

Link clicks will not result in a POST request without JavaScript.

Magento Url helper has the syntax

Mage::getUrl('module/controllerfile/action',array('id',1))

which would result in a lookup of the frontName for module and would give you for example

http://site.com/module/controllerfile/action/id/1/

which you could then access with Mage::app()->getRequest()->getParam('id').

If you have multiple URLs involved (like a form post), you can also redirect the user within the controller by using

$this->_redirect('module/controllerfile/action', array('id',1))

You can also create a query string with

$this->_redirect('module/controllerfile/action', array('_query',array('param1'=>'val','param2'=>'val'))).
