Hi,

Shortcode is a shortcut code that helps you run the helper function rwmb_meta without touching the code, it uses to display the field value for a specific case/post.

If you want to show the field value of all posts (portfolios) in a shortcode, please create a custom shortcode to show all portfolios and its custom field. Follow this documentation https://codex.wordpress.org/Shortcode_API.

Thanks Long but this does not explain how we pull the postID from each object automatically, can you please advise how we can add the postID to a Metabox custom field automatically?

Im using this shortcode to display a single image: [rwmb_meta id="field_id" object_id="15"]

how would I add a class to this image via the shortcode?

Hi,

The shortcode does not support to add the custom class. You can try to wrap the shortcode in a <div> tag. Just like:
```
<div class="my-custom-class">
    [rwmb_meta id="field_id" object_id="15"]
</div>
```
Or use the Builder to add the custom class to the field https://share.getcloudapp.com/X6u0nXzj.
