Keep these following tags in your pocket and learn them by heart , soon you will be on your way to worpress !

Theme Structure
If we want to create a WordPress theme, these following files must be included in order to be a standard
theme. we can create a theme using fewer files but this is the way to do it.

header.php – header section
index.php – main section
sidebar.php – sidebar section
footer.php – footer section
single.php – post template
page.php – page template
comments.php – comments template
search.php – search content
searchform.php – search form
archive.php – archive
functions.php – special functions
404.php – error page

Template Include Tags
These tags are usually used in a single PHP file to include other files from the theme. For example we can
use the get_header tag in index.php in order to include the head in the theme.
< ?php get_header(); ?>
< ?php get_sidebar(); ?>
< ?php get_footer(); ?>
< ?php comments_template(); ?>

The Loop
we will often see “the loop” as reference in many tutorials or samples. This piece of code helps we display
wer posts on a blog. By entering custom HTML or PHP code inside the loop, we will make every post to
benefit from that custom code. we can use the loop mainly in wer index.php file but also in other files
when we want to display multiple posts.
< ?php if(have_posts()) : ?>
< ?php while(have_posts()) : the_post(); ?>
// Custom HTML & PHP code
< ?php endwhile; ?>
< ?php else : ?>
< ?php endif; ?>

WordPress Conditional Tags
Conditional tags are simple but helpful tags that can be used to customize how wer blog will work. For
example if the page is the home page, we will type a class called “current-cat”. < ?php if(is_home()) {
?> class=”current-cat”< ?php } ?>. This is a part of the code which I will present we a little bit later
in this article.
is_page() – when a page is displayed
is_category() – when a category is displayed
is_home() – when the user is on the home page(blog)
is_front_page() – when the user is on the home page (blog or page)
is_single – when a single post is displayed
is_sticky() – check if a post is sticky

WordPress Navigation Menu
This thing is different based on how we want wer blog to work. we can have a menu based on pages, on
categories or on both. In every way we will need a home page link. In this case here the the 2 approaches
for the menu.
<ul id=”menu”>
<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>

Pages based menu
<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>

Display N posts from a category
On the first page we have in the sidebar 2 sections for latest tips and latest graphic ratings. Those sections
were made with the help of the query_posts.
< ?php query_posts(‘category_name=Name Here&showposts=10’); ?>
Custom Template File
In WordPress we can insert any additional template file that is none of the ones in the first section. In this
way we can make wer own template file and embed it in wer theme.
< ?php include (TEMPLATEPATH . ‘/searchform.php’); ?>
Template Bloginfo Tags
These tags are used to display information regarding wer blog, information that can be customized inside
the WordPress Administration panel.
< ?php bloginfo(‘template_url’); ?> – Displays the URL of the template
< ?php bloginfo(‘pingback_url’); ?> – Displays the pingback URL
< ?php bloginfo(‘stylesheet_url’); ?> – Displays the URL for the template’s CSS file
< ?php bloginfo(‘wpurl’); ?> – Displays URL for WordPress installation
< ?php bloginfo(‘name’); ?>
< ?php bloginfo(‘name’); ?> – Title of the blog
< ?php bloginfo(‘charset’); ?> – Displays the character set
< ?php bloginfo(‘description’); ?> – Displays the description of the blog
< ?php bloginfo(‘url’); ?> – Displays the address of the blog
< ?php bloginfo(‘rss2_url’); ?> – Displays the RSS URL
< ?php wp_list_cats(); ?> – Displays the categories
< ?php get_calendar(); ?> – Displays the calendar

Common WordPress Tags :
As we know WordPress has a lot of code that can be embedded in themes in order to make them complex
and powerful. Here are some of the common snippets that are used in most of the templates.
< ?php wp_get_archives() ?> – Displays a date-based archives list
