WordPress Template Tags

Template tags are used within themes to retrieve content from your database.

The content could be anything from a blog title to a complete sidebar.

Template tags are the preferred method to pull content into your theme because: they can print dynamic content; they can be used in multiple theme files; and they separate the theme into smaller, more understandable, sections.

the_content​()                      Get post content
the_excerpt​()                      Get the post excerpt
the_title​()                        Get the title of the post
the_permalink​()                    Display post link
the_category​(​', '​)                 Display category of a post
the_author​()                       Show post author
the_ID​()                           Display post ID
edit_post_link​()                   Show Edit link for a post
next_post_link​(​'%link'​)            Display next page URL
previous_post_link​(​'%link'​)        Display previous page URL
get_links_list​()                   Retrieve blogroll links
wp_list_pages​()                    Retrieve all pages
wp_get_archives​()                  Retrieve archive for the site
wp_list_cats​()                     Retrieve all categories
get_calendar​()                     Show the built-in WordPress calendar
wp_register​()                      Show register link
wp_loginout​()                      Displays login or logout links (for registered users)

Include Tags

Use these tags to include templates to your theme.

<?php​ get_header(); ​?>               Includes header.php and display its content
<?php​ get_sidebar(); ​?>              Includes sidebar.php
<?php​ get_footer(); ​?>               Includes the footer.php
<?php​ comments_template(); ​?>        Load specific template for comments

Useful Header Functions

site_url​()                              Get WordPress site url
wp_title​()                              Get page title
bloginfo​(​'name'​)                        Get blog name
bloginfo​(​'description'​)                 Get blog description
get_stylesheet_directory_uri​()          Get stylesheet directory URI
bloginfo​(​'atom_url'​)                    Get Atom feed URL
bloginfo​(​'rss2_url'​)                    RSS 2.0 URL

The Loop

The Loop is the default mechanism WordPress uses for outputting posts through a theme’s template files.

<?php​ ​if​ ( have_posts() ) : ​?>
  <?php​ ​while​ ( have_posts() ) : the_post(); ​?>
    // Display post content 
  <?php​ ​endwhile​; ​?>
<?php​ ​endif​; ​?>

WordPress Menu and Sidebars

Default Navigation Menu

<?php​ wp_nav_menu(); ​?>

Specific Navigation Menu

<?php​ wp_nav_menu( ​array​(​'menu'​ => My Navigation​' )); ?>

  <​li​ <?​php​ ​if​(​is_home​()) { ?> class="current-cat" ​<?php​ } ​?>​>
    <​a​ ​href​=​"<?php bloginfo('home'); ?>"​>Home</​a​>
  </​li​>
  ​<?php​ wp_list_categories(​'title_li=&orderby=id'​);​?>
</​ul​>

Page Based Navigation

<​ul​ ​id​=​"menu"​>
  <​li​ <?​php​ ​if​(​is_home​()) { ?> class="current-page-item" ​<?php​ } ​?>​>
    <​a​ ​href​=​"<?php bloginfo('home'); ?>"​>Home</​a​>
  </​li​>
​  <?php​ wp_list_pages(​'sort_column=menu_order&depth=1&title_li='​);?​ >
</​ul​>

Registering New Sidebar

Add the following code to your functions.php file to register a new sidebar.

add_action( ​'widgets_init'​, ​'theme_slug_widgets_init'​ );
function​ ​theme_slug_widgets_init​() {
  register_sidebar( ​array​(
​    'name'​ => __( ​'My Sidebar'​, ​'theme-slug'​ ),
​    'id'​ => ​'sidebar-1'​,
​    'description'​ => __( ​'Description',​ ​'theme-slug'​ ),
    'before_widget'​ => ​'<li id="%1$s" class="widget %2$s">'​,
