For a recent project I wanted to get all pages by page template. Looking at the codex for WP_Query I wasn’t able to find anything for page templates. Digging further, I was able to use custom meta queries.

The meta query key is: _wp_page_template

The meta query value is the file name of the page template.

Here’s an example:

$pagesByPageTemplate = new WP_Query(array(
    'post_type' => 'page',
    'meta_query' => array(
        array(
            'key' => '_wp_page_template',
            'value' => 'page-custom_page_template.php'
        )
    ),
));

That’s it! Now continue on with your WordPress loop!
