Which code correctly includes a custom footer template named footer-custom.php?

You want to include a footer template file named footer-custom.php instead of the default footer.php. Which code snippet does this correctly?

A <?php include('footer-custom.php'); ?>

B <?php get_footer('custom'); ?>

C <?php get_footer('footer-custom'); ?>

D <?php get_footer_custom(); ?>

💡 Hint

The get_footer() function accepts a name parameter without the 'footer-' prefix or '.php' extension.

Using get_footer('custom') loads footer-custom.php. The function appends 'footer-' and '.php' automatically.

Why does calling get_sidebar('left') fail to load sidebar-left.php?

You have a file named sidebar-left.php in your theme folder. Calling get_sidebar('left') does not display its content. What is the most likely reason?

Wordpress

<?php get_sidebar('left'); ?>

A The <code>get_sidebar()</code> function does not accept parameters.

B The sidebar-left.php file must be registered in functions.php before use.

C You must call <code>get_sidebar_left()</code> instead.

D The file <code>sidebar-left.php</code> is missing or misnamed in the theme directory.

💡 Hint

Check the exact file name and location in your theme folder.

The get_sidebar('left') function looks for sidebar-left.php in the theme folder. If the file is missing or named differently, it won't load.

How do WordPress template parts like header, footer, and sidebar improve theme development?

Why do WordPress themes use separate template files for header, footer, and sidebar instead of putting all HTML in one file?

A They allow reusing common page sections across multiple templates, making maintenance easier.

B They force WordPress to load pages slower but improve security.

C They prevent users from editing theme files directly in the admin dashboard.

D They automatically generate dynamic content without any PHP code.

💡 Hint

Think about how repeating code in many files affects updates.

Separating header, footer, and sidebar into template parts lets developers reuse code, so changes in one file update all pages using it.
