Meta Box

Hi, the extension and the plugin Meta Box does not set image size. The helper function (in the example above) has a parameter to get custom size for image.

Not sure what are you going to do with this, but why don't you just create new image size in your theme? It's something belong to theme's functionality.

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>';
}
