I want to add a hard coded footer into the...
footer.php of my site. This doesn't need to be "dynamic" (adding and removing widgets), it will be something standard like info about the site and specific links.
If I am correct this can be done either by
get_template_part( 'template-parts/', 'infofooter' );
get_sidebar( 'infofooter' );
In the second case I just have to name my file
Are both methods equally valid? What is the difference between a (non-dynamic) sidebar and a template part? Is it that a sidebar usually includes widgets?
