Hi @renar

I’m afraid you have several mistakes there. The hook should be “acf/save_post”, not “acf/save_post hook”. Here’s an example how I do it:

function my_acf_post_fieldb($post_id){

    // Field key where you want to update (c_address)
    $field_key = 'field_573d8df4646da';

    // The General Info post ID that you want to update
    $general_info_post_id = 99;
    
    // Get the saved value from the user profile
    $value = get_field('add_full_address', $post_id);
    
    // Check if the value exists or not
    if( $value ) {
        // Update the repeater field in the selected post
        update_field($field_key, $value, $general_info_post_id);
    }
}
add_filter('acf/save_post', 'my_acf_post_fieldb', 20);

I’m not sure how did you set the custom field to the General Info post type, so I just assume that you want to update the value on a selected post.

I hope this makes sense 🙂
