WordPress was originally created as a weblog or blog platform. But now WordPress has grown so powerful that you can use it to create any type of website and use it as a Content Management System (CMS). In this article, I’m going to share some of my WordPress tricks with you on how to make a better WordPress theme. I’m not a programmer nor developer, so I will focus more on the frontend development. Oh yeah, I forgot to mention that WordPress has made it so easy that even a non-programmer (designer like me) can build a wonderful website. My WordPress sites included: N.Design Studio, Best Web Gallery, Web Designer Wall, and some free WordPress Themes.

WordPress Conditional Tags

Conditional Tags are very useful when creating a dynamic WordPress theme. It allows you to control what content is displayed and how that content is displayed. Here are couple sample uses of Conditional Tags:

Dynamic Highlight Menu

Here is what I used to create a dynamic highlight menu on Best Web Gallery. In the first list item, if it is Home or Category or Archive or Search or Single, add class="current" to the <li> tag, which will highlight the "Gallery" button. Second item, if it is page with Page Slug "about", add class="current".

<ul id="nav">
  <li<?php if ( is_home() || is_category() || is_archive() || is_search() || is_single() || is_date() ) { echo ' class="current"'; } ?>><a href="#">Gallery</a></li>
  <li<?php if ( is_page('about') ) { echo ' class="current"'; } ?>><a href="#">About</a></li>
  <li<?php if ( is_page('submit') ) { echo ' class="current"'; } ?>><a href="#">Submit</a></li>
</ul>

Dynamic Title tag

Again, I use Conditational Tags to output dynamic <title> tag in the header.php.

<title>
<?php 
if (is_home()) {
	echo bloginfo('name');
} elseif (is_404()) {
	echo '404 Not Found';
} elseif (is_category()) {
	echo 'Category:'; wp_title('');
} elseif (is_search()) {
	echo 'Search Results';
} elseif ( is_day() || is_month() || is_year() ) {
	echo 'Archives:'; wp_title('');
} else {
	echo wp_title('');
}
?>
</title>

Dynamic Content

If you want to include a file that will only appear on the frontpage, here is the code:

<?php if ( is_home() ) { include ('file.php'); } ?>

Feature post highlighting

Let’s say categoryID 2 is your Feature category and you want to add a CSS class to highlight all posts that are in Feature, you can use the following snippet in The Loop.

<?php if ( in_category('2') ) { echo ('class="feature"'); } ?>

Unique Single template

Suppose you want to use different Single template to display individual post in certain category. You can use the in_category to check what category is the post stored in and then use different Single template. In your default single.php, enter the code below. If the post is in category 1, use single1.php, elseif in category 2, use single2.php, otherwise use single_other.php.

<?php
  $post = $wp_query- >post;

  if ( in_category('1') ) {
  include(TEMPLATEPATH . '/single1.php');

  } elseif ( in_category('2') ) {
  include(TEMPLATEPATH . '/single2.php');

  } else {
  include(TEMPLATEPATH . '/single_other.php');

  }
? >

Unique Category template

Suppose you want to use different Category template to display specific category. Simply save your Category template as category-2.php (note: add “-” and the categoryID number to the file name). So, category-2.php will be used to display categoryID 2, category-3.php will be used for categoryID 3, and so on.

Display Google Ad after the first post

A lot of people have asked me for this. How to display a Google ad after the first post? It is very simple. You just need to add a variable ($loopcounter) in The Loop. If the $loopcounter is less than or equal to 1, then include google-ad.php code.

<?php if (have_posts()) : ?>

<?php while (have_posts()) : the_post(); $loopcounter++; ?>

  // the loop stuffs

  <?php if ($loopcounter <= 1) { include (TEMPLATEPATH . '/ad.php'); } ?>

<?php endwhile; ?>

<?php else : ?>

<?php endif; ?>

Query Posts

You can use query_posts to control which posts to show up in The Loop. It allows you to control what content to display, where to display, and how to display it. You can query or exclude specific categories, so you get full control of it. Here I will show you how to use query_posts to display a list of Latest Posts, Feature Posts, and how to exclude specific category.

Display Latest Posts

The following code will output the 5 latest posts in a list:

<?php query_posts('showposts=5'); ?>

<ul>
  <?php while (have_posts()) : the_post(); ?>
  <li><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></li>
  <?php endwhile;?>
</ul>

Display Feature Posts

Let’s say categoryID 2 is your Feature category and you want to display 5 Feature posts in the sidebar, put this in your sidebar.php:

<?php query_posts('cat=2&showposts=5'); ?>

<ul>
  <?php while (have_posts()) : the_post(); ?>
  <li><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></li>
  <?php endwhile;?>
</ul>

Exclude specific category

You can also use query_posts to exclude specific category being displayed. The following code will exclude all posts in categoryID 2 (note: there is a minus sign before the ID number):

<?php query_posts('cat=-2'); ?>

<?php while (have_posts()) : the_post(); ?>
  //the loop here
<?php endwhile;?>

Tips: you can overwrite the posts per page setting by using posts_per_page parameter (ie. <?php query_posts('posts_per_page=6'); ?>)

Custom Fields

Custom field is one the most powerful WordPress features. It allows you to attach extra data or text to the post along with the content and excerpt. With Custom Fields, you can literally trun a WordPress into any web portal CMS. On Web Designer Wall, I use Custom Field to display the article image and link it to the post.

First add the Custom Field in the post.

custom fields

To display the article image and attach it with the post link, put the following code in The Loop:

<?php //get article_image (custom field) ?>
<?php $image = get_post_meta($post->ID, 'article_image', true); ?>

<a href="<?php the_permalink() ?>"><img src="<?php echo $image; ?>" alt="<?php the_title(); ?>" /></a>

Tips: don’t forget WordPress allows you to create/store multi keys and the keys can be used more than once per post.

I used the same methodology and created a very dynamic template at Best Web Gallery, where I used Custom Fields to display the site thumbnail, tooltip image, and URL.

WP List Pages

Template tag wp_list_pages is commonly used to display a list of WP Pages in the header and sidebar for navigation purpose. Here I will show you how to use wp_list_pages to display a sitemap and sub-menu.

Site map

To generate a sitemap (sample) of all your Pages, put this code in your sitemap Page Template (note: I exclude pageID 12 because page12 is my sitemap page and I don’t want to show it):

<ul>
  <?php wp_list_pages('exclude=12&title_li=' ); ?>
</ul>

Dynamic Subpage Menu

Put this in your sidebar.php and it will output a subpage menu if there are subpages of the current page:

<?php
$children = wp_list_pages('title_li=&child_of='.$post->ID.'&echo=0');
if ($children) { ?>

<ul>
  <?php echo $children; ?>
</ul>
<?php } ?>

Page Template

If you are using WordPress as a basic webpage management, you better don’t miss out the Page Template feature. It allows you to customize how the Pages should be displayed. To use Page Template, first you need to create a Page Template, then you can assign the Page to specific template.

Here is how the Page Template structured (ie. portfolio.php):

<?php
/*
Template Name: Portfolio
*/
?>

<?php get_header(); ?>
  //the loop here
<?php get_footer(); ?>

When you are writing or editing a page, look on the right tab “Page Template” and you should see the available templates.

page template

WordPress Options

There are many built-in options in the Admin panels that can make your site much nicer. Here are some of them:

Custom Frontpage

By default, WordPress displays your blog posts on the frontpage. But if you want to have a static page (ie. welcome or splash page) instead, you can set that in Admin > Options > Reading.

frontpage setting

Permalinks

Default WordPress uses www.yoursite.com/?p=123 for your post URLs, which is not URL nor search engine friendly. You can change the Permalinks setting through Admin > Options > Permalinks. Personally, I like to set the Permalinks to: /%category%/%postname%/

permalinks

Category prefix

Default WordPress category prefix is "category" (ie. yoursite.com/category/cat-name/). By entering "article" in the Category base (Options > Permalinks), your category URLs will become: yoursite.com/article/cat-name/

category prefix

    This is a FANTASTIC resource! As someone who just started switching over from Drupal to WordPress, I have to say this is beyond “timely” – Great post and thanks for all the fantastic content – I too have had a lot of issues with the “categories” and setting my “variants” with them so to speak – but this post really clarified a lot for me. Thanks again!

    yesterday I have changed permalinks of my site from /%year%/%month%/%day%/%post-name% to /%post-name% , I have installed advanced permalink plugin and redirection working ok.
    But problem in categories page & tab below header navigation bar when I click them it shows 404 error, but tag and archive works ok from widgets links. How to restore the category tab and category page so that it works as like before.
    Previously it was showing in browser address http://newtechworld.net/category/tech-news/, and now it is showing 404 error, and when I click on cat name from widget area it is giving address like – http://newtechworld.net/?cat=18.
    Also I want to know, is it not possible to show sub-categories below parent category in drop down in navigation bar.
    Thanks in advance

    Do you know if it would be possible to have a certain post or page show depending on which day of the week people are visiting the site. For instance if someone visited on a Tuesday the homepage would display a page that you have designated to show on Tuesdays then if someone came to the site on Wednesday the homepage would show a post or page that you have designated to show on Wednesday etc.

    Arcade games usually have very short levels, simple controllers, iconic characters, and increasing levels of complexity. They are designed as short adrenaline-driven thrillers compared to most console games, which have more complex play and stronger storylines. One reason for this is that since the game is coin-operated, the player rents the game for as long as their game avatar survives on the field. Any game on a console or a PC can be referred to as ‘arcade game’ if it has these attributes.
