External file to get a custom field from post?

    Hi everyone.

    I’m baffled by how to start something – I’d like to have a separate file (link.php) that could query the wordpress post table for a specific custom field/key. The file would be located among all other files.

    Say something like link.php?id=3&key=mycustomfield

    So that it would return that field value to me.

    Thanks!!

  • Save the code below as link.php in your theme’s folder:

    <?php
/* get custom field value for a post id */
require('../../../wp-blog-header.php');
get_header();
$id = (intval($_GET['id'])) ? intval($_GET['id']) : 0;
$key = (isset($_GET['key'])) ? urldecode($_GET['key']) : '';
$value = get_post_meta($id,$key,true);
echo "<p>ID:$id KEY:$key VALUE:$value</p>";
get_footer();
?>

    Call it like this:

    https://yourdomain.com/wp-content/themes/yourtheme/link.php/?id=123&key=mycustomfield
