Hi there,

I want to autogenerate title and slug from ACF fields and terms and I’ve already created a function which works nearly perfect. My only issue is, the date output is not working correctly. I don’t want the present date but the correct date from the two custom_fields from date picker. Here is the custom code:

// Create Auto Title for 'Veranstaltungen'
add_action('save_post', 'wpb_autogenerate_events_title', 10, 3);

function wpb_autogenerate_events_title($post_id, $post, $update) {
    // Check if it's the 'events' CPT and if the title is empty.
    if ('veranstaltungen' !== $post->post_type || !empty($post->post_title)) {
        return;
    }

    // Fetch terms from 'category' and 'nameselection' taxonomies.
    $category_term = wp_get_post_terms($post_id, 'veranstaltungskategorie', ['fields' => 'names']);
    $nameselection_term = wp_get_post_terms($post_id, 'winzertax', ['fields' => 'names']);

    // Fetch the 'date' custom field created with ACF Pro.
    $date_start = get_field('datum_beginn', $post_id);
	$date_end = get_field('datum_ende', $post_id);
	
	$date_start_form = date( "dmY", strtotime($date_start));
	$date_end_form = date( "dmY", strtotime($date_end));

    // Combine the terms and the date to form the title.
    $new_title = join(' <br>bei ', array_merge((array) $category_term, (array) $nameselection_term));
	$new_titleslug = join('-', array_merge((array) $category_term, (array) $nameselection_term, (array) $date_start_form, (array) $date_end_form));
	
    // Prepare the slug from the title.
    $new_slug = sanitize_title($new_titleslug);

    // Update the post.
    wp_update_post([
        'ID' => $post_id,
        'post_title' => $new_title,
        'post_name' => $new_slug, // This is the slug.
    ]);
}

Could you please help me why the output isn’t correct?
