Hi Marcelo,

This is what happening.
The ACF file field stores the value as an integer in the database.
So when you use a custom field column and select this ACF key, it will show you an ID as default.

The URL type can make a plain URL a clickable link, but the initial value must already be a URL.
Since your value is not an URL, the column will display no value at all.
You could try the field type ‘Post Title’ as it will give you the files title and a link to the edit page for that file (not the fileurl).

If you really want a link to the file, you have to use one of our filters to make the link yourself. You should be able to manage it with this filter: https://www.admincolumns.com/documentation/filter-reference/cac-column-meta-value/

You could do something like this.

function acp_make_link_from_acf_id_value( $value, $object_id, $column ) {
	$custom_field_key = 'acf_file'; // Change it to your ACF key

	if ( 'column-meta' == $column->get_type() && $custom_field_key == $column->get_field() ) {

		$value = $value ? wp_get_attachment_link( $value ) : '';

	}

	return $value;
}
add_filter( 'cac/column/meta/value', 'acp_make_link_from_acf_id_value', 10, 3 );

Hi Marcelo,

I think the snippet is correct but maybe one of the checks is failing.
Try to debug it by alway output the key

echo $column->get_field()
or
$value = $column->get_field()

In that case you know for sure if the values is changed at all. And you’ll get the correct ACF key to work with.
Or only try just one if statement instead of two. If that doesn’t work, try to build the function from scratch

function acp_make_link_from_acf_id_value( $value, $object_id, $column ) {
	$value = 'value is changed';
	return $value;
}
add_filter( 'cac/column/meta/value', 'acp_make_link_from_acf_id_value', 10, 3 );
