HOWTO: Show Page Template Name
A cool function to simply display the path of the WordPress template used on a particular page:
<?php echo get_page_template() ?>
How/when to use this?
If you are trying to debug a site and want to quickly see what page template is used – you can put that PHP code into footer.php and it will then echo out the path so you can quickly and easily see what template is being used.
Using meta_query With WordPress 3.1+
With WordPress 3.1 – we now have the ability to use “meta_query” to show posts associated with a certain custom field. I recently used this in order to create an events listing widget for a client. I needed to query posts in the “Events” category and that had a time stamp defined (which happened to be the start date of the event). The client wanted to show only current/future events (today or later) and wanted to show them in order by the closest event date to the furthest away.
Getting the general query together was a snap – but the orderby did not work unless I had the meta_key defined (this is documented but was overlooked initially).
Example
$now = time(); $args = array( 'category_name' => 'Events', 'meta_query' => array( array( 'key' => 'sdac_event_time_stamp', 'value' => $now, 'compare' => '>=', 'type' => 'NUMERIC' ) ), 'meta_key' => 'sdac_event_time_stamp', 'order' => 'ASC', 'orderby' => 'meta_value_num' ); $events_query = new WP_Query( $args);
If you take a look at the query itself – the trick was to capture the time now ($now) and then use the compare within the meta_query. Overall – this sort of query makes working with custom fields a lot easier. If you have not checked it out yet – take a look.

Remove “Private:” From WordPress Titles
I needed to be able filter out the text “Private:” for posts and pages that were password protected but did not want to edit any core WordPress files. To filter out that text, I added the following code into my functions.php file (within my theme directory):
function remove_private_prefix($title) { $title = str_replace( 'Private:', '', $title); return $title; } add_filter('the_title','remove_private_prefix');
(I also posted this filter in the WordPress Support Forum)
