wordpress Show Your Favorite Tweets with WordPress

by in , 0

Just replace the URL in the fetch_rss line below with the RSS feed to your Twitter favorites. In fact this will work with any RSS feed.

<?php
    include_once(ABSPATH . WPINC . '/feed.php');
    $rss = fetch_feed('http://twitter.com/favorites/793830.rss');
    $maxitems = $rss->get_item_quantity(3); 
    $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>
        <a href='<?php echo $item->get_permalink(); ?>'>
            <?php echo $item->get_title(); ?>
        </a>
    </li>
    <?php endforeach; ?>
</ul>

wordpress Shortcode in a Template

by in , 0

Shortcodes in WordPress are bits of text you can use in the content area to invoke some kind of function to accomplish certain tasks. For example, video embedding in WP 2.9+ uses the shortcode. You can write your own shortcodes, and plugins often offer their functionality via shortcodes as well.

But what if you want to use a shortcode from within a template instead of with the content of a Post/Page? You can invoke it with a special function:

<?php echo do_shortcode("[shortcode]"); ?>

wordpress Run Loop on Posts of Specific Category

by in , 0 

<?php query_posts('cat=5'); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
   <?php the_content(); ?>
<?php endwhile; endif; ?>

If you were to use this, for example, in a left sidebar which ran before the main loop on your page, remember to reset the query or it will upset that main loop.

<?php wp_reset_query(); ?>

  require('/server/path/to/your/wordpress/site/htdocs/blog/wp-blog-header.php');
  query_posts('showposts=1');
?>

wordpress Reset Admin Password Through Database

by in , 0

You'll need to be able to run SQL on that database, like for example, through phpMyAdmin.

UPDATE `wp_users` SET `user_pass` = MD5( 'new_password_here' ) WHERE `wp_users`.`user_login` = "admin_username";
