One of the more useful things I’ve learned while developing with Wordpress is the use of the $wpdb class which allows you to use the Wordpress database functions in your plugin without including the header and footer. This is useful when you’re using a bit of jQuery or AJAX to submit a form and get a call back w/o getting all the Wordpress headers and HTML.

// Wordpress root directory (from plugin's directory)
$path = '../../../';
 
include_once($path . 'wp-config.php');
include_once($path . 'wp-load.php');
include_once($path . 'wp-includes/wp-db.php');
 
function attachments() { 
    global $wpdb;
 
    $sql = "SELECT * FROM ".$wpdb->posts." WHERE post_type = 'attachment'";
    $rows = $wpdb->get_results($sql); 
    $html = '';
 
    foreach($rows as $row) { 
      $html .= '<div><a href="'.$row->guid.'">'.$row->post_title.'</a></div>';
    }
 
    return $html;
}
 
// Outputs a list of the attachments (media files)
echo attachments();

add_filter('admin_head','myplugin_tinymce');
 
function myplugin_tinymce() {
    wp_admin_css('thickbox');
    wp_print_scripts('jquery-ui-core');
    wp_print_scripts('jquery-ui-tabs');
    wp_print_scripts('post');
    wp_print_scripts('editor');
    add_thickbox();
    wp_print_scripts('media-upload');
    if (function_exists('wp_tiny_mce')) { wp_tiny_mce(); }
}

2. Call the editor in your plugin

the_editor($content_to_load);

I’ve been a developer for over 10 years now and I stumbled upon an extremely simple bit of coding that I’ve never either seen or realized was out there. It’s so simple that I feel like a complete n00b for not knowing this! read more »

IM has the immediacy of telephone without the interruption, and the convenience of email without the delay. For years I’ve been an advocate for instant messaging in the work place so I figured I’d take a few minutes and explain why I feel IM should be implemented and how!

I like to consider myself pretty tech-savvy, as are most of my colleagues and friends.

I was shocked to learn that we are in the minority of small business owners with a website or using social media for networking and promotion.
