WordPress - Requested URL Not Found

Question

<a href="where.php" class="nav-item nav-link">Where Are We</a>

Trying to do a nav bar link in my header.php, but getting a 404, despite the file being in the same directory as my index.php. Also the index.php requires the header.php file. Not too familiar with WordPress.

Answer 1

you have to add your link like this

<a href="<?php echo esc_url(get_theme_file_uri('where.php'));?>">where are we?</a>

the function get_theme_file_uri generates url to the theme folder.
