Get object in Advanced link

Hello,

Thanks for the feedback!

There is no need for additional filter here. You can retrieve the unformatted value of any ACF Field using by passing a parameter in your get_field(). See documentation.

For example, here the formatted value of the Advanced Link:

get_field('my_advanced_link', 270);

array(
    "title"  => "Text",
    "url"    => "https://www.domain.com/category-1",
    "target" => "0",
)

Here is the unformatted value of the Advanced Link. Note the false at the end:

get_field('my_advanced_link', 270, false);

array(
    "type"   => "term",
    "term"   => "1",
    "title"  => "Text",
    "target" => "0",
)

With the term id you can retrieve the Term Object using get_term() (See documentation), and then construct your thumbnail.

Hope it helps!

Have a nice day!

Regards.
