Is it possible to generate a variable variable with the following code, specifically the value for the “show” argument?

I have the PHP parsing set to input, and this does work for outputting text, but it does not seem to work for what I have in mind.

{exp:weblog:categories weblog="{embed:my_blog}" parent_only="no" show_empty="no" style="linear" show="{<?php echo '{embed:my_blog}' ?>_navbar_categories}"}

Napco,

that’s not going to work you would need to approach it like

<?php

$cats = '1|3|4';

?>
{exp:weblog:categories weblog="{embed:my_blog}" parent_only="no" show_empty="no" style="linear" show="<?php echo $cats ?>"}

And do whatever you need to create that list of IDs outside the categories tag itself. Not knowing your set-up I can’t say how you would do that.

I can move this thread to the CodeShare corner if you wish to have some Community help on this one?

I wound up going another route, thanks anyway.

Glad you found a solution, Napco.  If there’s anything else we can help with, please make a new post.  Thank you!
