Creating custom user upgrade page.

[Aethelwulf]

I've spent the past few hours dabling into creating a custom xenforo user upgrade page based off of the actual user upgrade page. So far I've been able to customize the UserUpgrade page by tweaking it to begin creating a tiered perm. payment model but now I want to put the account upgrade on its own page node.

I've been following one of the video tutorials posted on here, taking from what they've done, I've created a php class and function that calls the XenForo_Model_UserUpgrade but the way I'm doing this is obviously wrong. With so many arrays buried in another array and then burried in another array after that, it gets a bit.. well.. errm. Could someone maybe tell me what I would need to call to get the upgrade model to display correctly with the template file posted below?

*Edit* I think I've got it.

class Dev_PurchasePage extends XenForo_Model
{

     public static function respond(XenForo_ControllerPublic_Abstract $controller, XenForo_ControllerResponse_Abstract $response)
    {
        $upgradeModel = $controller->getModelFromCache('XenForo_Model_UserUpgrade');
        $response->params['payPalUrl'] = 'https://www.paypal.com/cgi-bin/webscr';
        $response->params['available'] = $upgradeModel->prepareUserUpgrades($purchaseList['available']);
        $response->params['purchased'] = $upgradeModel->prepareUserUpgrades($purchaseList['purchased']);
        $response->templateName = 'purchase';
    }
}

Template for seperate Account Upgrade. Just a copy/paste from the account_upgrade template.

<xen:title>{xen:phrase account_upgrades}</xen:title>

<xen:require css="account_upgrades.css" />

<xen:if is="{$available}">

        you will only ever have to pay the difference between the two. </b><br />
