  • Hi @acf-support

    I’m not running any other plugins. Only the latest version or WordPress and the latest version of ACF.

  • Ok, update_field() wasn’t working for me, even though I’m sure it was right. I am instead using $wpdb to update the field in the database, which is working. I’m not marking this as resolved as the issue with update_field() still remains. If anyone could shed any light on this please let me know.

  • I have now narrowed down the issue to update_field(). Here is mine:

    update_field('field_552cb019acd87',$seminarDate,353);

    This isn’t working. $seminarDate is a timestamp. Can anyone see any reason why this wouldn’t work?

  • Update:

    @jonathan in my DB ACF is saving the datetime as a UNIX timestamp. I have edited the code to use update_field() and it still isn’t saving to the database, using the field name or field key.

    function updateSeminarTime($post_id)
    {
    
        // bail early if no ACF data
        if (empty($_POST['acf'])) {
    
            return;
    
        }
    
        // array of field values
        //$fields = $_POST['acf'];
    
        // specific field value
        $post = get_post($post_id);
        $expertId = $post->post_author;
        $userTimeZone = getTimeZone($expertId);
        $userTimeZoneOffset = get_timezone_offset($userTimeZone, 'UTC');
        $seminarDate = $_POST['acf']['seminar_date'];
        $seminarDate = strtotime($seminarDate);
        $seminarDate = $seminarDate + $userTimeZoneOffset;
        //$seminarDate = date('m/d/y h:mm tt', $seminarDate);
        echo $seminarDate;
        echo $userTimeZoneOffset;
        echo $post_id;
        update_field('field_552cb019acd87',$seminarDate,$post_id);
    }
    
    // run before ACF saves the $_POST['acf'] data
    add_action('acf/save_post', 'updateSeminarTime', 20);

    When I save the post, it automatically takes me to the new post. How can I debug this and see any echo’d values etc?

  • Hi @jonathan

    I was trying to intercept the form submission before it was actually written to the DB using the hook/filter above. Is that not what this filter is for? I know it is doing something as the datetime is no longer written into the DB, it is just blank. Do I then need to update (SQL) that field? Seems like there should be a way to simply update the $_POST['acf']['seminar_date'] before it is inserted into the DB.

  • Update: So I have found this http://www.advancedcustomfields.com/resources/acfsave_post/.

    I am hooking into it, but the date isn’t actually being written to the database. Not sure why not. Here is my code:

    function updateSeminarTime( $post_id ) {
    
        // bail early if no ACF data
        if( empty($_POST['acf']) ) {
    
            return;
    
        }
    
        // array of field values
        //$fields = $_POST['acf'];
    
        // specific field value
        $post = get_post( $post_id );
        $expertId =  $post->post_author;
        $userTimeZone = getTimeZone($expertId);
        $userTimeZoneOffset = get_timezone_offset($userTimeZone,'UTC');
        $seminarDate = $_POST['acf']['seminar_date'];
        $seminarDate = strtotime($seminarDate);
        $seminarDate = $seminarDate + $userTimeZoneOffset;
        $seminarDate = date('m/d/y h:mm tt',$seminarDate);
        $_POST['acf']['seminar_date'] = $seminarDate;
    
    }
    
    // run before ACF saves the $_POST['acf'] data
    add_action('acf/save_post', 'updateSeminarTime', 1);

    I’m wondering if I am writing the format wrong. BTW I have tried with date() and formatting it to a string and also just as a UNIX timestamp.

  • Hi @dacrosby Thanks for your suggestion. Is any one else aware of another method? This way seems like a bit of a hack.
