Meta Box

Hi, can you please post your code?

The new version 4.7.1 fixes this bug. Please update.

Due to a change in Meta Box 4.7 with "attributes" param, the old code for Group doesn't work. I've just updated the extension to make it work with new version of Meta Box. Please update.

Thanks for reporting.

Glad that you made it 🙂

The rwmb_meta returns the value for current post. So the code above works only if you're viewing the attachment page. To make sure it works, you can provide the attachment ID as the 3rd param: rwmb_meta( 'sw_link', 'type=url', $attachment_id );

Hi,

The file_input field store the URL of the image in the post meta, so if you use rwmb_meta() function, you will get the URL of the file.

In case you want to use more sizes of the file, WordPress has a helper function to retrieve attachment ID from the URL attachment_url_to_postid(). The sample code looks like this:

$speakergroup = rwmb_meta( 'cf_speakers' );
foreach ( $speakergroup as $speakerdata ) {
  $attachment_id = attachment_url_to_postid( $speakerdata['cf_speakerpic'] );
  list( $src ) = wp_get_attachment_image_src( $attachment_id, 'thumbnail' );
  echo '<a href="' . $speakerdata['cf_speakerurl'] . '" target=_blank><img src="' . $src . '" class="circle wp-post-image"></a>';
}

Did you put it in the post content? The shortcode shows value only if you put it in the post content (or where it's rendered).

If you put it in another place like theme's files, you should use:

<?php echo '[rwmb_meta meta_key="image3"][/rwmb_meta]'; ?>
