The Conditional Tags can be used in your Template files to change what content is displayed and how that content is displayed on a particular page depending on what conditions that page matches.

These tags (always of the form is_*(), such as is_home()), report what sort of page is being displayed (e.g. the Main Page, a Category Archive, etc.) and can be used within a Template to control the Template’s output depending on what the tags report.

Example – is_front_page() , is_admin(), is_single() , is_page() , is_category() , is_archive()

The Loop

The Loop is PHP code used by WordPress to display posts. Using The Loop, WordPress processes each post to be displayed on the current page, and formats it according to how it matches specified criteria within The Loop tags. Any HTML or PHP code in the Loop will be processed on each post.

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
