Hi, I don't understand this documentation: https://docs.metabox.io/fields/file/

I am trying to just get the file URL from the array, but I haven't managed to. It would be really helpful if on the documentation you could include how to do it with a shortcode. Because then those using page builders can see very clearly how to adapt for their use case. I think my issue is that I don't understand arrays. Where am I going wrong?
```
add_shortcode( 'uploaded_paper_link', function () {
$id = get_queried_object_id();
$uploaded_files = rwmb_get_value( 'academicpdf', ['attribute' => 'url'], $id );
	foreach ( $uploaded_files as $uploaded_file );
	return $uploaded_file;
});
```

Hi Yasmine,

Can you please share the code that creates the field pdf? Is it a subfield in a cloneable group?

Hi Long,

Here it is. You ask if it is cloneable, it wasn't. Should it not be an array then? I only thought it was an array as when I tried to output directly, the link only said 'array'!
```
 [
                'name'             => __( 'Upload Research Paper PDF', 'your-text-domain' ),
                'id'               => $prefix . 'pdf',
                'type'             => 'file',
                'desc'             => __( 'Optional<small>Upload a PDF to give readers an easy way to access your research</small>', 'your-text-domain' ),
                'max_file_uploads' => 1,
                'columns'          => 6,
                'multiple'         => false,
                'tab'              => 'academicreference_builder',
],
```

Hi,

Ok, here is the sample code to output the file URL
```
add_shortcode( 'uploaded_paper_link', function () {
    $id = get_queried_object_id();
    $uploaded_files = rwmb_meta( 'academicpdf', '', $id );
    $output = '';
    foreach ( $uploaded_files as $uploaded_file ) {
        $output .= $uploaded_file['url'] . '<br>';
    }
    return $output;
});
```
Let me know how if it helped.
