This goes in your page template or sidebar template where you want your submenu to appear. It is outside the loop.

<?php
 $parent_title = get_the_title($post->post_parent);
 if($post->post_parent)
 $children = wp_list_pages("title_li=&sort_column=menu_order&child_of=".$post->post_parent."&echo=0&depth=1"); else
 $children = wp_list_pages("title_li=&sort_column=menu_order&child_of=".$post->ID."&echo=0&depth=1");
 if ($children && is_page()) { ?>
     <ul class="menu">
       <li <?php if ( is_page() && $post->post_parent ) {} else { ?>class="current_page_item"<?php } ?>><a href="<?php echo get_permalink($post->post_parent) ?>"><?php echo $parent_title;?></a></li>
          <?php echo $children; ?>
     </ul>
 <?php } ?>

As it stands, the only issue with this code, is that when you are on the parent page, the class that identifies it as current does not appear. If you know of a solution for this, please do tell.

Updated Oct 7th, 2011 to include “current” state on parent page.

This is assuming that the timthumb script is in your theme’s directory: wp-content/themes/mytheme/timthumb.php


<?php
$args = array( 'post_type' => 'attachment', 'orderby' => 'menu_order', 'order' => 'ASC', 'post_mime_type' => 'image' ,'post_status' => null, 'post_parent' => $post->ID );
$attachments = get_posts($args);
	if ($attachments) {
	foreach ( $attachments as $attachment ) { ?>
      <img src="<?php bloginfo('template_url'); ?>/thumb.php?w=200&amp;h=200&amp;zc=1&amp;src=<?php echo wp_get_attachment_url( $attachment->ID , false ); ?>" alt="<?php the_title(); ?>" width="200" height="200" border="0" />
<?php	}
	} ?>

To have each thumbnail link to the full sized original image, have the anchor href point to

<?php echo wp_get_attachment_url( $attachment->ID , false ); ?>

If you’ve ever shared a link on your Facebook account, you’ve noticed the nifty Title, Image and Description that get automatically loaded to provide an attractive link. Depending on how your particular theme is built, sometimes you’ll have to cycle through several images, before the actual appropriate post image shows up with your Facebook link.

Here is a bit of code you can add to the head section of the header.php file of your theme (Try adding it before the wp_head(); tag) to guarantee that your theme is optimized for Facebook link sharing. It will also make sure that the appropriate post image is the first one that Facebook looks for.

Code Last Updated June 3rd 2011

This update allows you to set the “Featured Image” as the the image that Facebook shows when your link is shared. Secondly, it allows you to set a default image, in case your post does not make use of a “featured image”. You can use a promo graphic, or your logo for this default, by saving it in your themes directory, in a /images/ directory with the file name as default_icon.jpg. Or you can alter the image directory in the code below

	$thumb = $thumb[0];
	$default_img = get_bloginfo('stylesheet_directory').'/images/default_icon.jpg';

	<meta property="og:description" content="<?php bloginfo('description'); ?>" />
    <meta property="og:image" content="<?php  if ( $thumb[0] == null ) { echo $default_img; } else { echo $thumb; } ?>" />
<?php  }  ?>

Be Aware: Updating your code will not have immediate effects with Facebook, as Facebook will cache your shared link. It could take up to a few hours before the shared link would work properly. You can try to share one of your links that has not been shared before, to test that it is working proper.

Coming soon: At the moment, if you don’t have an image set as “featured”, it will just default to your chosen default image in your theme directory. I’ll be adding the ability for it to check for the first image used in the post if there is no featured image. So the order will be 1) Featured, if not 2) First Image in post, if not 3) Use default image in theme directory.

Now inside your posts just wrap an image URL with the img shortcode. Add height, width, alt, and class to it for more flexibility.

7/15/2011 – Updated to allow use within a text widget.

// Image resize in content
// To Use: {img w=600 h=200 class=alignleft alt=My Photo}http://mysite.com/photo.jpg{/img}
function timmyimg($atts, $content = null) {
	extract(shortcode_atts(array(
		'w' => '600',
		'h' => '250',
		'class' => 'alignnone',
		'alt' => ''
	), $atts));
	return "<img src='". get_bloginfo('template_directory') . "/timthumb.php?src=".$content."&w=".$w."&h=".$h."' alt='".$alt."' class='wp-post-img ".$class."' />";
}
add_shortcode('img', 'timmyimg');
 
// Allows this shortcode to work within a text widget
add_filter('widget_text', 'do_shortcode');

<?php
    $thumb = get_post_meta($post->ID,'_thumbnail_id',false);
    $thumb = wp_get_attachment_image_src($thumb[0], false);
    $thumb = $thumb[0];?>
 
   <img src="<?php  echo $thumb; ?>" alt="" />

Combine this with the Timthumb script for control over image size. IE:

 
<?php
   $thumb = get_post_meta($post->ID,'_thumbnail_id',false);
   $thumb = wp_get_attachment_image_src($thumb[0], false);
   $thumb = $thumb[0];
  if ( has_post_thumbnail() ) { ?>
    <img src="<?php bloginfo('template_directory'); ?>/timthumb.php?src=<?php echo $thumb; ?>&amp;w=150&amp;h=150&amp;zc=1"
        alt="<?php the_title(); ?>" width="150" height="150" />
<?php } ?>

Not Recommended, But Available Option

This will output the URL to an image with the size predefined by ‘post-thumbnail’ in your functions file when registering the functionality for post images.

<?php
    $thumb = get_post_meta($post->ID,'_thumbnail_id',false);
    $thumb = wp_get_attachment_image_src($thumb[0], 'my-custom-size', false);
    $thumb = $thumb[0];
    echo $thumb; ?>

The above code is referencing ‘my-custom-size’, which we can see below as being 405×180. Typically it is not advised to use these predefined sizes as it will overload your uploads directory with additional sizes, and it puts strain on your server when uploading images. Better to use the above method with the Timthumb script to get an exact image size, while making use of image caching.

if ( function_exists( 'add_theme_support' ) ) { // Added in 2.9
	add_theme_support( 'post-thumbnails' );
	set_post_thumbnail_size( 50, 50, true ); // Normal post thumbnails
	add_image_size( 'my-custom-size', 405, 180, true );
}

This is a minor hack of the Fotobook plugin (Version 3.1.8) for WordPress by Aaron Harp. Fotobook is originally meant to apply your personal photo albums into WordPress, but we’re going to make one small code tweak to instead pull the albums from the fan page that we administer.

After installing the plugin, go ahead and activate it and grant the permissions to your Facebook account.

Next, visit your Facebook fan page, and click into an album so you’re viewing all photos in one particular album. In the address bar you’ll see a &id=123123123. Copy that ID number.

In the plugin directory open the fotobook.php file and head down to line 243 and look for this code.

$uid = $session['uid'];

Swap that code for this

//$uid = $session['uid'];
$uid = 123123123;

With the 123123123 being the ID code for your fan page.

If you have a custom URL set for your fan page you might notice that the album photos are not showing. To correct that move down around line 809 in fotobook.php and look for:

if(!is_numeric($id)) return false;

And code it out of use by adding // in front so that it now looks like

//if(!is_numeric($id)) return false;

Back in the plugin administration page, go ahead and import your albums. And you should be good to go!

With a thanks to B. Thibault in the forums at the Fotobook Application Page.

Here is a solution to prevent revisions from being created, as well as removing all revisions from your database.

Prevent Revision Creation

Open wp-config.php and add this to the very bottom of the file, before the php closing tag.

define('WP_POST_REVISIONS', false);

This completely turns off any revision creation. If you’d like to restrict revision creation to a set amount per post, you can change ‘false’ for the number of revisions you’d like stored.

Remove All Revisions From Database

Open up your database in phpmyadmin and run this SQL Query.

DELETE FROM wp_posts WHERE post_type = "revision";

And now you’ll have a more tidy database.

As I have yet resisted joining the ranks of the Mac cult, we’ll be using PC server software. I am aware of XAMPP, WAMP, and I personally use VertrigoServ for no other reason than it is the only one I’ve tried. (Mac cultists can use MAMP.)

This Tutorial Is Based On VertrigoServ

They say that cleanliness is next to godliness, and in that vein let us install our server in a organized location. On my desktop, I actually use a whole separate hard drive to store my server. If you don’t have the luxury of a dedicated HDD, then your local disk or C:\ will be fine.

01. Installing The Server

Create the following directory: C:\usr\. Then run the server installer, and be sure to install the software in the C:\usr\ location. If you installed the VertrigoServ software, then the “public web” files will be located in C:\usr\www\. So let’s download and install WordPress inside C:\usr\www\wordpress\ and then be sure to fire the server up after installation.

02. Setup The Database

So we’ll need to have a database created before we can install WordPress. In your web browser, navigate to http://localhost/phpmyadmin and login. There should be the default user and password if this is your first time. Find it by clicking the VertrigoServ icon in the bottom right tray, and selecting “Help and Readme”. Be sure to change your passwords once you get in. Default login is root/vertrigo.

Now that we’re in PHPmyAdmin, let’s create a database for our local WordPress install. Type in your desired database name, and hit the “Create” button.

03. Installing WordPress

With the database created, we can now input our database details into the wp-config.php file of our WP install.

// ** MySQL settings ** //
define('DB_NAME', 'database_name');    // The name of the database from step 2
define('DB_USER', 'root');     // Vertrigo uses root as the default username
define('DB_PASSWORD', 'vertrigo_password'); // the password used to get into your local phpmyadmin
define('DB_HOST', 'localhost');    // 99% chance you won't need to change this value
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');

Now we can pull open our browser, and navigate to http://localhost/wordpress and begin the installation of WordPress.

The http://localhost/ address looks into the \usr\www\ directory. So whatever the name of the directory we installed in, is what we’ll need to punch in after localhost/. For example, if I installed an application in \usr\cms\, I will need to navigate to http://localhost/cms in order to pull up that site.
