I am making some unproductive attempts to insert the block created by the extension to Magento within the phtml files of the theme and already tried to insert as a block of Slider Revolution itself and also put the shortcode of the plugin inside a native block of Magento to try to call the html by inserting the block into the theme file. I have errors of type variable $this is calling an object that does not exist.
I can not edit the xml files of the theme, so I did not even try to do that. The code I'm trying to insert inside phtml is this:
echo $this->getLayout()->createBlock('nwdrevslider/revslider')->setAlias('fashion_slider')->toHtml();
Error
Fatal error: Using $ this when not in context object in ...
Can anyone help me find a solution or follow a reasoning to make it work?
