Thank you for your fast support )

ok I did a custom field now I want to get the first url in the content to be written automatically in the new field created.

I know there is a function called :

function get_link_url() {
    $content = get_the_content();
    $has_url = get_url_in_content( $content );
 
    return ( $has_url ) ? $has_url : apply_filters( 'the_permalink', get_permalink() );
}  

can I use this function with this field? and how?

Thank you for your time and help
