How To Pass Variable From Controller To Template

Store Builder in detail Hints & Modifications
#1

nw that I have my custom product table extension working, I need to present some UI to manage the data (admin products.manage) and view (products.view) it



I created a controller in my addon, and the controller gets fired, I can access the database, and properly get the data (get), and I'm sure on post I can put it back.



now to show the data on the screen.



I started down the html block path, but you can't access template variables in these blocks, too late in the process cycle…



so, I created a static template, and this template is fired as expected (on view at the moment)…



but, how do I address the variable in the template… all the samples don't seem to match whatever is required in 4.2.4



my controller does



Registry::get('view')->assign('var_name',var_value);



my template does


{$var_name}

some content2



on the product entry view on the customer site, I see
$var_name
some content2

so I am missing a small piece of info.
#2

I write a log file from my controller, it said I was in a get request, with mode = view. (as expected).

the variable also appears in debug mode in the templates view variables list as expected, with the proper value.



ps it works now,

${var_name}





I hate that I can't edit my posts to clean up typos.
