Twitter is getting very famous among bloggers. Many bloggers are now displaying their most recent tweet on their blog. If you want to display your most recent tweet on your blog simply place this code where you want to display it in your WordPress theme.

    <?php
    $username = "TwitterUsername"; // Your twitter username.
    $prefix = ""; // Prefix – some text you want displayed before your latest tweet.
    $suffix = ""; // Suffix – some text you want display after your latest tweet.
    $feed = "http://search.twitter.com/search.atom?q=from:" . $username . "&rpp=1";

    function parse_feed($feed) {
    $stepOne = explode("<content type=\"html\">", $feed);
    $stepTwo = explode("</content>", $stepOne[1]);
    $tweet = $stepTwo[0];
    $tweet = str_replace("&lt;", "<", $tweet);
    $tweet = str_replace("&gt;", ">", $tweet);
    return $tweet;
    }

Many Blogs are now having guest posts on their site. Some of these guest authors are one-time only authors, so there is no point in creating a separate profile for them just so you can display their name in the post. The smarter way to do this is by using the following code.

Open you single.php, or page.php in your template and add the following code where you display the author name:

    <?php $author = get_post_meta($post->ID, "guest-author", true);
    if ($author != "") {
    echo $author;
    } else {
    the_author();
    } ?>

Have you seen sites that display most recent comments in their sidebar with user gravatars. Well this can be done easily with these codes. Simply paste the following code anywhere you want to display the most recent comments.

    <?php
    $query = "SELECT * from $wpdb->comments WHERE comment_approved= '1'
    ORDER BY comment_date DESC LIMIT 0 ,5";
    $comments = $wpdb->get_results($query);

    if ($comments) {
    echo '<ul>';
    foreach ($comments as $comment) {
    $url = '<a href="'. get_permalink($comment->comment_post_ID).'#comment-'.$comment->comment_ID .'" title="'.$comment->comment_author .' | '.get_the_title($comment->comment_post_ID).'">';
    echo '<li>';
    echo '<div class="img">';
    echo $url;
    echo get_avatar( $comment->comment_author_email, $img_w);
    echo '</a></div>';

WordPress has fields for fields for author contacts, but it has not been updated in ages. So by default you do not have an ability to add author’s twitter or facebook. With this hack you can add this information on their profile page.

First open your functions.php and paste the following code:

    <?php
    function my_new_contactmethods( $contactmethods ) {
    // Add Twitter
    $contactmethods['twitter'] = 'Twitter';
    //add Facebook
    $contactmethods['facebook'] = 'Facebook';

    return $contactmethods;
    }
    add_filter('user_contactmethods','my_new_contactmethods',10,1);
    ?>

WordPress lets you display Excerpts, but up until version 2.9 you could not control the excerpt length. With the following code, you can increase the length from default 55 words to as many words as you like. Open your functions.php file and add the follwowing codes in there:

    // Changing excerpt length
    function new_excerpt_length($length) {
    return 100;
    }
    add_filter('excerpt_length', 'new_excerpt_length');

Did you see sites with a magazine style theme who are displaying posts from a specific category. Sometimes only the most recent post. Well you can do this too easily.

    <?php
    query_posts('showposts=1&cat=3');
    while(have_posts()) : the_post();
    ?>
    <ul>
    <li><h3><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></h3>

    <ul><li><?php the_content(); ?></li>
    </ul>
    </li>
    </ul>
    <?php endwhile; ?>

Assuming that you have already created a custom page template and/or already have The Loop ready, paste the following code before the loop.

    <?php
    /* Get all sticky posts */
    $sticky = get_option( 'sticky_posts' );

    /* Sort the stickies with the newest ones at the top */
    rsort( $sticky );

    /* Get the 5 newest stickies (change 5 for a different number) */
    $sticky = array_slice( $sticky, 0, 5 );

    /* Query sticky posts */
    query_posts( array( 'post__in' => $sticky, 'caller_get_posts' => 1 ) );
    ?>

This hack comes becomes very useful when you are running a contest because you might
be posting information such as clues or hints that you don’t want to stay up for ever.
of manually removing the article, you can just make it expire automatically. It also works
if you have a product that you are offering a discount on. You posted it on your blog,
but you don’t want that discount to stay on your blog after its over. So you can remove it
automatically with this code.

All you need to do is replace your WordPress Loop with this code:

<?php
    if (have_posts()) :
    while (have_posts()) : the_post(); ?>
    $expirationtime = get_post_custom_values('expiration');
    if (is_array($expirationtime)) {
    $expirestring = implode($expirationtime);
    }

custom styling and avoid the annoying feedburner button.

    //get cool feedburner count
    $whaturl="http://api.feedburner.com/awareness/1.0/GetFeedData?uri=your feedburner id";

    //Initialize the Curl session
    $ch = curl_init();

    //Set curl to return the data instead of printing it to the browser.
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    //Set the URL
    curl_setopt($ch, CURLOPT_URL, $whaturl);

    //Execute the fetch
    $data = curl_exec($ch);

    //Close the connection

Did you ever want to display a different number of posts on different pages. For example
on your category pages, you want to display 10 posts which you can control from your
Admin panel, but another page you want to show only 5 posts. Well this tutorial is just for you.

Open a Template file where you want to display an x number of recent posts:

    // if everything is in place and ready, let’s start the loop

    // to display ‘n’ number of posts, we need to execute the loop ‘n’ number of times
    // so we define a numerical variable called ‘$count’ and set its value to zero
    // with each iteration of the loop, the value of ‘$count’ will increase by one
    // after the value of ‘$count’ reaches the specified number, the loop will stop
    // *USER: change the ‘n’ to the number of posts that you would like to display

Have you seen other bloggers who display their other blog’s feed on their site.

    $rss = fetch_feed('http://feeds.feedburner.com/wpbeginner');
    $maxitems = $rss->get_item_quantity(5);
    $rss_items = $rss->get_items(0, $maxitems);
    ?>
    <ul>
    <?php if ($maxitems == 0) echo '<li>No items.</li>';
    else
    // Loop through each feed item and display each item as a hyperlink.
    foreach ( $rss_items as $item ) : ?>
    <li>

Have you ever been to a site and saw this cool feature? They have a link in their top
