在WordPress中使用the_post_thumbnail的圖片標題

Question

當在主循環中的帖子中顯示the_post_thumbnail()圖片時，有沒有辦法顯示圖片標題？

謝謝！感謝所有的幫助。

Answer 1

我計算出來：

/************************************************************\ 
* Fetch The Post Thumbnail Caption 
\************************************************************/ 

function the_post_thumbnail_caption() { 
    global $post; 

    $thumbnail_id = get_post_thumbnail_id($post->ID); 
    $thumbnail_image = get_posts(array('p' => $thumbnail_id, 'post_type' => 'attachment')); 

    if ($thumbnail_image && isset($thumbnail_image[0])) { 
    echo $thumbnail_image[0]->post_excerpt; 
    } 
} 

Answer 2

下面是一個更簡單的和更短的代碼：

<?php the_post_thumbnail(); 
echo get_post(get_post_thumbnail_id())->post_excerpt; ?> 

Answer 3

if(!function_exists('get_post_thumbnail_caption')) { 
    function get_post_thumbnail_caption($post_id = null) { 
     $post_id = (null === $post_id) ? get_the_ID() : $post_id; 
     $thumbnail_id = get_post_thumbnail_id($post_id); 
     if ($thumbnail = get_post($thumbnail_id)) 
      return $thumbnail->post_excerpt; 
     return ''; 
    } 
} 

if(!function_exists('the_post_thumbnail_caption')) { 
    function the_post_thumbnail_caption($post_id = null) { 
     echo get_post_thumbnail_caption($post_id); 
    } 
} 

if(has_post_thumbnail()) { 
    the_post_thumbnail(); 
    the_post_thumbnail_caption(); 

    $caption = get_post_thumbnail_caption(123); 
    if('' == $caption) 
     echo '<div class="caption">'.$caption.'</div>'; 
} 

Answer 4

作爲WordPress的4.6的，功能the_post_thumbnail_caption()已被添加到核心（/ WP - 包括/後縮略圖的template.php）。

使用這裏發佈的代碼將導致錯誤：

Fatal error: Cannot redeclare the_post_thumbnail_caption()
