Most Commonly Used WordPress Code Snippets

May24

I’ve been developing WordPress themes for more than 2 years and based from my own experience and personal preferences, here are the most common WordPress code snippets that I use. Please do check it out and if you learn a thing or two, let me know in the comments.

Display Recent Posts

There are different methods I use for this kind of function and it depends on the need and how the template is laid out. You can check out the 3 methods that I use below. I hope you find it useful in your projects.

Method 1: This code displays the 10 latest posts. You can place this code anywhere on your template. For more info on wp_get_archives() you may want to check out the codex

<ul>
<?php wp_get_archives('type=postbypost&limit=10'); ?>
</ul>

Method 2: This is just basically the loop except that we defined a number of posts to be shown using the query_posts() function. You may want to read more on query_posts()

<?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>

Method 3: This is I think the best way to display the recent posts since it’s very simple and you can customize the way the posts are displayed. You can use this code anywhere on your template. Read more about the get_posts() function.

<?php
$recentposts = get_posts('numberposts=12&category=4');
	foreach ($recentposts as $post) :
	setup_postdata($post);
?>
<li><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>

Display Recent Comments

I found this piece of code somewhere around the web but I don’t know who the original source is. So the credit goes to him or her. This piece of code will display the 7 most recent comments.

<?php
global $wpdb;
$sql = "SELECT DISTINCT ID, post_title, post_password, comment_ID,
comment_post_ID, comment_author, comment_date_gmt, comment_approved,
comment_type,comment_author_url,
SUBSTRING(comment_content,1,30) AS com_excerpt
FROM $wpdb->comments
LEFT OUTER JOIN $wpdb->posts ON ($wpdb->comments.comment_post_ID =
$wpdb->posts.ID)
WHERE comment_approved = '1' AND comment_type = '' AND
post_password = ''
ORDER BY comment_date_gmt DESC
LIMIT 7";
$comments = $wpdb->get_results($sql);
$output = $pre_HTML;
$output .= "\n<ul>";
foreach ($comments as $comment) {
$output .= "\n<li>".strip_tags($comment->comment_author)
.": " . "<a href=\"" . get_permalink($comment->ID) .
"#comment-" . $comment->comment_ID . "\" title=\"on " .
$comment->post_title . "\">" . strip_tags($comment->com_excerpt)
."&hellip;</a></li>";
}
$output .= "\n</ul>";
$output .= $post_HTML;
echo $output;?>

Display Categories

There are different ways in displaying categories and most of the time I like the categories to be displayed in a simple list.

<h4>Categories</h4>

<ul>
<?php wp_list_categories('use_desc_for_title=0&title_li=&show_count=0'); ?>
</ul>

Display Archives as Simple List

Method 1: This will display the archives in a month list. I usually place this on the sidebar. Learn more about wp_get_archives.

<h4>Archives</h4>
<ul>
	<?php wp_get_archives('type=monthly'); ?>
</ul>

Method 2: This will display all the posts in a simple list. I usually use this on an archives page template.

<ul class="archives">
<?php
$myposts = get_posts('numberposts=-1&offset=0');
foreach($myposts as $post) :
?>
<li><small><?php the_time('d.m.y') ?></small> <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>

<?php endforeach; ?>
</ul>

Display Tagclouds

This will display the tags in a tagcloud. This is the simplest on how to use it. For more details you may check out wp_tag_cloud() from the WordPress codex.

<?php wp_tag_cloud('smallest=8&largest=22'); ?>

Display Blogroll

This will display the links in a simple plain list. More on wp_list_bookmarks.

<ul>
<?php wp_list_bookmarks('title_li=&categorize=0'); ?>
</ul>

While I know that these are not all of the most commonly used WordPress snippets, I hope this post will still help out people who want to learn WordPress. I have written this post so it can serve as a reference for me and by all means you can make it your reference too. But if you want to learn more on WordPress functions you can always go to the Codex or you can get a copy of WordPress for Dummies.

  23. salam kenal gan..!!

  25. Wondering about expanding the recent posts to include up to 20 words of the body of the post? I went with your option 3.

  26. Hi just wanted to give you a quick heads up and let
    you know a few of the images aren’t loading correctly. I’m not sure why but I think its a linking issue.
    I’ve tried it in two different browsers and both show the same outcome.

  27. thanks ,the article very usefull

  28. Nice list of code snippets, definitely worth while bookmarking for future use, I am planning on putting a couple of my code snippets up online.

    I think one of the most difficult things to achieve is a breadcrumb or nice pagination.

    Thanks for the snippets.

  29. Hi, i think that i saw you visited my blog so i came to “return the favor”.I’m trying to find
    things to improve my website!I suppose its ok to use a few of your ideas!!

  30. I enjoy what you guys tend to be up too. Such clever
    work and reporting! Keep up the awesome works guys I’ve
    added you guys to blogroll.

  31. Undeniably consider that that you said. Your favorite reason seemed to be at the web the easiest thing to understand of.

    I say to you, I definitely get annoyed whilst folks think about worries that they plainly don’t know about.
    You controlled to hit the nail upon the top as smartly as outlined out the entire
    thing without having side effect , other people
    can take a signal. Will probably be back to get more. Thanks

  32. The other day, while I was at work, my sister stole my apple ipad and tested to see if it can survive a 40 foot drop, just so she can be a youtube sensation.
    My iPad is now broken and she has 83 views. I know this is completely off topic but I had to
    share it with someone!

  33. After lymph runs through the system collecting pollutants, it
    passes through the kidneys and liver for cleansing.
    It may also be that environmental factors come into play as well and
    interact with those genes. Moving to a new home, relocating to a different location or changing jobs all affect the
    status quo. Sensors attached to the scalp feed your
    data into a computer. The hunters intend to sacrifice
    Ralph to the beast.
