Создание пользовательских полей и мета-блоков

Question

Код, над которым я работаю, возвращается, но не возвращает значение для телефонного номера

Я пытаюсь создать персонализированную запись для офисов

Я что-то упустил, и яне вижу этого.

Answer 1

В этой функции:

function locations_footer() {
    $args = array('post_type'=>'locations',);
    $location_loop = new WP_Query($args);
    if($location_loop->have_posts()):
        while($location_loop->have_posts()):
            $location_loop->the_post();
            $locations = get_post_meta($post->ID,'location_fields',true);
            $telephone = $locations['telephone'];
            $title = get_the_title();
            $content = get_the_content();
            echo'Title:'.$title.'<br>Telephone:'.$telephone.'<br>Content:'.$content.'';
        endwhile;
    endif;
    wp_reset_postdata();
}
add_action('wp_footer','locations_footer');

в этой строке, по-видимому, отсутствует "s" $locations = get_post_meta($post->ID,'location_fields',true); должно быть $locations = get_post_meta($post->ID,'locations_fields',true); также для $post->ID, убедитесь, что значение действительно, если не можетхочу попробовать это: https://developer.wordpress.org/reference/functions/get_the_id/

Answer 2

Попробуйте этот код. Я прокомментировал эту строку //add_action('add_meta_boxes','show_locations_fields_meta_box');. Это добавит 2 мета-поля.

, а также изменится в сохранении почтового индекса.

function locations_footer() {
    $args = array('post_type'=>'locations',);
    $location_loop = new WP_Query($args);
    if($location_loop->have_posts()):
        while($location_loop->have_posts()):
            $location_loop->the_post();
            $locations = get_post_meta($post->ID,'location_fields',true);
            $telephone = $locations['telephone'];
            $title = get_the_title();
            $content = get_the_content();
            echo'Title:'.$title.'<br>Telephone:'.$telephone.'<br>Content:'.$content.'';
        endwhile;
    endif;
    wp_reset_postdata();
}
add_action('wp_footer','locations_footer');

function locations_post(){
    register_post_type('locations', array(
        'labels' => array(

    $old = get_post_meta($post_id,'locations_fields',true);
    $new = $_POST['locations_fields'];
     update_post_meta($post_id,'locations_fields',$new);

}
add_action('save_post_locations','save_locations_fields_meta');
