  1. The comments_template() only accepts two parameters: $file (string) and $separate_comments (Boolean). So, it does not have a way to pass an arbitrary variable as a parameter.

    The two methods I generally use are:

    1. Globalize the variable
    2. Wrap the variable inside a function that returns the data you want, and then call it wherever you need it.

  2. You can use php session variables to utilize the myvar variable anywhere you want.

    if(!$_SESSION['myvar']){

    $_SESSION['myvar'] = 'myvar';

}

echo $_SESSION['myvar'];
