This extension enables the merchants and developers to preview mail templates from the backend with real data.

• PHP >= 5.2.0
• Mage_Adminhtml

• Magento CE >= 1.7.0.2 (only tested on this version)

1. Install the extension by copying the files into your Magento root or by using a modman compatible tool (modman, Composer).
2. Clear the cache, logout from the admin panel and then login again.

1. Remove the extension by removing the files.

The functionality can be used in the backend section System > Transactional Emails.

• Click on a template in the transaction email grid and navigate to the Preview Email tab.
• Choose the Template type. This is necessary because an e-mail template is not fixed to a certain template type. For example you load a New account template and select the Template type New account.
• Unfortunately, you have do use common sense to find out which data are necessary for which template at the moment. It doesn't harm if you enter more data than necessary so if you're in doubt fill in more fields.

If you introduce new variables into existing mail templates, you have to provide Magento with actual models (ie. orders, customers, ...).

You can do so by observing the hackathon_emailpreview_render_email_before event. You will be provided with:

• templateType. Use the template type to decide if you have to modify the parameters for this type of template.
• templateParams. This Varien_Object contains the parameters (ie. variables like orders, customers, ...) that will be passed to the mail template renderer.

Adding a customer with real data as a template parameter looks like this:

$templateParams = $observer->getEvent()->getData('templateParams');
$requestParams = $templateParams->getRequestParams();
$customerId = $requestParams['customerId'];
$customer = Mage::getModel('customer/customer')->load($customerId);
$templateParams->setCustomer($customer);

If you have any issues with this extension, open an issue on GitHub.
