I try to display a custom block in email template and pass the order object. I tried

{{block type='module/blockname' area='frontend' order=$order template='template/module.phtml'}}

Block is like:

Namespace_Module_Block_Blockname extends Mage_Core_Block_Template

The module.phtml exists and using it in another phtml with


works fine. But in email template the block won't show up. Do i miss some configuration in layout.xml? I tried so many things to get this working, perhaps someone can give me a hint how to manage this.

I also tried with layout handle:

    <block type="module/blockname" name="blockname" template="namespace/template.phtml"></block>

and call with:

{{layout area="frontend" handle="some_handle" order=$order}}

I know that you can include static blocks using e.g.:

{{block type="cms/block" block_id="static-block-id" }}

That block simply uses _toHtml() to output the content from the static block.

protected function _toHtml()
    $blockId = $this->getBlockId();
    return $html;

Similarly, you could try and populate the _toHtml() function with HTML in your module to output what ever you need to output. You cannot use PHP variables such as $order to pass in your data for processing.

    From Magento 1.9. this works but don't forget to add cms/block to the allowed blocks (System > Permissions > Blocks).

If you are facing the same problem as I am you might have forgotten to white list your block... You need to add an entry in the permission_block table with your block path.

    Specifically allow cms/block under System -> Permissions -> blocks Oct 20, 2017 at 20:27
