Weird (?) problem

Oh ok.

The instructions are way too fuzzy for non-coders like me. I tried to use the code from the instructions under “Pulling Attachments to your Theme”:

<pre><?php print_r( $attachment ); ?></pre>

…but this only displays the attributes followed by their value.

The right way to do this is to follow the instructions under Retrieve Attachment Attributes. E.g. use

<?php echo $attachments->field( 'title' ); ?>
<?php echo $attachments->field( 'caption' ); ?>

etc.

??

Also, if anyone would like to add their attachments with a shortcode, try this:

function list_publication_attachments( $atts ) {

  ob_start(); ?>

  <?php $attachments = new Attachments( 'attachments' ); /* pass the instance name */ ?>
  <?php if( $attachments->exist() ) : ?>
    <div>
      <?php while( $attachment = $attachments->get() ) : ?>
        <?php echo $attachments->image( 'thumbnail' ); ?>
        <h3><a href="<?php echo $attachments->url(); ?>"><?php echo $attachments->field( 'title' ); ?></a></h3>
        <p><?php echo $attachments->field( 'caption' ); ?></p>
      <?php endwhile; ?>
    </div>
  <?php endif; ?>

  <?php
    $sc = ob_get_contents();
    ob_end_clean();
    return $sc;
}
add_shortcode('publications', 'list_publication_attachments');

Add it to functions.php or in a file called shortcodes.php and include it in functions.php with

include('shortcodes.php');

This will let you add the list of attachments by using [publications] as a shortcode in any WP-post/page.

Happy coding!
