у меня проблема с моим метабоксом: я добавляю новую мету в пользовательский тип записи «запуск». код здесь :

 function product_thumbnail_url($pid){
$image_id = get_post_thumbnail_id($pid);  
$image_url = wp_get_attachment_image_src($image_id,'screen-shot');  
return  $image_url[0];  
}

function list_my_images_slots( $cpt = false ){
$list_images = apply_filters('list_images',array(
    'image1' => '_image1',
    'image2' => '_image2',

    'image4' => '_image۴',
    'image5' => '_image5',
    'image6' => '_image6',
    'image7' => '_image7',
    'image8' => '_image8',
    'image9' => '_image9',
    'image10'=> '_image10',
    ), $cpt );
    return $list_images;
    }

add_meta_box('elnazimage', __('گالری تصاویر'), "elnazimage", 'startup',     'normal', 'core');
//add_meta_box('elnazimage', __('گالری تصاویر'), "elnazimage", 'opportunities', 'normal', 'core');
}


add_action('save_post', 'save_image_metabox'); 
function save_image_metabox($post_ID){ 
// on retourne rien du tout s'il s'agit d'une sauvegarde automatique
if ( defined('DOING_AUTOSAVE') amp;amp; DOING_AUTOSAVE )
    return $post_id;

$list_images = list_my_images_slots();

    }

}
  

я использую функцию get_multi_images_src(), но возвращаю примечание впереди:(.

также не работает следующий код: get_post_meta($post->ID,’image1′,true);

мета-сохранение работает корректно.

пожалуйста, помогите мне
