I’ve created a child theme of the Paloma FSE theme which works as expected.

However. When I use the following code within the functions.php file and the following code in my /patterns/footer-default.php file, the var_dump of the return value of the function always returns False.

Because I added the add_action in the functions.php it also runs without invoking the function in the footer (at the top of the page). This invocation correctly functions on the page and returns the expected true return value. But when I manually invoke the isPageFrontOrContact() function, it seems to not be able to figure out on which page it is. Because when I do a var_dump of the global $post I receive NULL as response.

Why is this not working when manually invoking the function from the footer.php file?

functions.php:

add_action('template_redirect', 'isPageFrontOrContact');
function isPageFrontOrContact() {
    if(is_page(55) || is_front_page()){
		return true;
	}
	return false;
}

/patterns/footer-default.php

<?php
var_dump(isPageFrontOrContact());
?>
