Add to functions.php file:
function get_ID_by_page_name($page_name) {
global $wpdb;
$page_name_id = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_name = '".$page_name."' AND post_type = 'page'");
return $page_name_id;
}Now you can use this function in templates when you need an ID of a specific post/page and all you have is the name.
Post thumbnails are pretty useful and pretty easy to use in WordPress. Simply add:
add_theme_support('post-thumbnails'); To a theme's functions.php file and you'll get a Featured Image module on the admin screen for posts which allows you to select one.
It is also very easy to output that image as an HTML <img>:
the_post_thumbnail();But what if you just need the URL? Say, you're going to use it as a background-image on an element rather than a content image. Unfortunately there is no super easy/obvious function for that.
Within the loop, you'll have to do:
$thumb_id = get_post_thumbnail_id();
$thumb_url_array = wp_get_attachment_image_src($thumb_id, 'thumbnail-size', true);
$thumb_url = $thumb_url_array[0];Then $thumb_url will be that URL.
Apparently there is no succinct WordPress function for just returning the content of a particular page by the ID of that page. This is that.
function get_the_content_by_id($post_id) {
$page_data = get_page($post_id);
if ($page_data) {
return $page_data->post_content;
}
else return false;
}
This will find what the ID is of the top-most parent Page, in a nested child page. For example, this page you are literally looking at is nested under
<?php
if ($post->post_parent) {
$ancestors=get_post_ancestors($post->ID);
$root=count($ancestors)-1;
$parent = $ancestors[$root];
} else {
$parent = $post->ID;
}
?>$parent will be the correct ID. For example, for use with wp_list_pages.

Some very easy copy-and-paste code here to add to the template for blog posts to allow for Facebook "liking" of the article. Probably best in the single.php template underneath where it outputs the content of the post.
<iframe src="http://www.facebook.com/plugins/like.php?href=<?php echo rawurlencode(get_permalink()); ?>&layout=standard&show-faces=true&width=450&action=like&font=arial&colorscheme=light" scrolling="no" frameborder="0" allowTransparency="true" id="facebook-like"></iframe>
For your functions.php file in the theme.
add_theme_support( 'post-formats',
array(
'aside',
'gallery',
'link',
'image',
'quote',
'status',
'video',
'audio',
'chat'
)
);
add_post_type_support( 'post', 'post-formats' );
add_post_type_support( 'page', 'post-formats' );
// and other custom post types if you have them
<?php $recent = new WP_Query("page_id=**ID**"); while($recent->have_posts()) : $recent->the_post();?>
<h3><?php the_title(); ?></h3>
<?php the_content(); ?>
<?php endwhile; ?>The above code can be used within the regular page loop. Replace **ID** with the ID of the page you wish to embed.
