Magento add Template to Widget and pass variables

Question

I've build my first Magento Widget. Now in the /Block/MyBlock.php I would like to call a *.phtml template and hand over some variables, given in the widget.

I managed to call my template within the /Block/MyBlock.php with

    protected function _toHtml() {
        return Mage::getSingleton('core/layout')->createBlock('core/template')->setTemplate('webmasterei/Header.phtml')->toHtml();
        $brand_header_logo = $this->getData('brand_header_logo');
        $this->setData('logo',$brand_header_logo);
}

Now I want to echo $brand_header_logo within the Header.phtml. How do I do that? Is the template actually in the right place or should I make that with this?

<template>
                <required>1</required>
                <visible>0</visible>
                <label>Template</label>
                <type>select</type>
                <value>path/to/template/template.phtml</value>

            </template>

How do I hand over the variables from the MyBlock.php in this case?

I tried now in the /template/Module/template.phtml

<?php echo $this->logo ?>

As layed out before but that doesn't work. I think I'm missing the connection here.

Answer 1

You can pass the variable to your template with:

 ->setData('logo', $brand_header_logo)

Then in your template file:

 <?php echo $this->logo ?>
