    hi,
    I would like to calculate a date + x days, is this plug in can to that
    i have an acf field date_from and i would like to display a date_to, but this code doesnt work (php statement)
    //date From
    $dateFrom= get_field(‘date_from’);

    // month to add
    $month = 2;

    // transform
    $dateFromTimestamp = strtotime($dateFrom);

    // calcul (seems to be wrong)
    $dateTo = date(‘d-m-Y’, strtotime(‘+’.$duree.’ month’, $dateFromTimestamp ));
    // set the field
    update_field( $date_to, $dateTo );

    HI @fmalinge – this plugin is designed to validate inputs of a particular field, but it can’t set the values of other fields. I do have an add-on planned that would be able to accomplish this, but it won’t be ready in the near term.

    Looking at your sample code, you probably want to hook to the meta update actions for the date_from field, then update your other meta field value. See this StackOverflow post for more info: https://wordpress.stackexchange.com/questions/16835/how-to-hook-update-post-meta-and-delete-post-meta

    add_action( 'added_post_meta', 'my_after_post_meta', 10, 4 );
add_action( 'updated_post_meta', 'my_after_post_meta', 10, 4 );
function my_after_post_meta( $meta_id, $post_id, $meta_key, $meta_value ){
    // check if it is the "date_from" meta key that was just updated
    if ( 'date_from' == $meta_key ) {
        // use the $meta_value to calculate 2 months in the future
        $date_to = date( 'd-m-Y', strtotime( '+2 month', strtotime( $meta_value ) ) );
        // update the "date_to" value
        update_post_meta( $post_id, 'date_to', $date_to );
    }
}
