Get declared variable in single.php to work in comments.php without re-declaring it [closed]

Question

I have declared a variable in my single.php

$title  = 'myvar';

Can I get it in my comments.php without re-declaring it again?

I use this code to get the comments.php templage:

<? comments_template( '', true );  ?>

Answer 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.

Answer 2

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

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

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

}

echo $_SESSION['myvar'];
