Hi,

I have a post loop and using the Insert Field button is fine for simple fields but I have issues with inserting Checkboxes and File Advanced fields into the loop.

For checkboxes, I have found a workaround:

{{ mb.rwmb_the_value( 'myfield', '', post.ID, false ) }}

It's probably not ideal, but it kind of works.

But I cannot figure out how to output raw URLs of PDF files from File Advanced fields. The usual "Insert Fields" button doesn't help.

How can I use such fields inside loops?

I also tried:

{{ mb.rwmb_meta( 'my_field_group_id', '', post.ID )['my_field_id'] }}

But it doesn't display anything...

Greetings,
Tom

Hi Tom,

The multiple setting is always set to true for this field so it will return an array when getting the field value. You need to create a loop to iterate through array elements to get each file info. For example
```
{% set my_file = mb.rwmb_meta( 'file_advanced', '', post.ID ) %}
{% for item in my_file %}
    {{ item.url }}
    <br>
{% endfor %}
```
Get more details on the documentation https://docs.metabox.io/fields/file-advanced/#template-usage

Thank you Long. The "set my_file" part was the missing piece. It works now.

Greetings,
Tom
