我有一个帖子格式库。我已经创建了一个元盒来添加我的图像：

function mytheme_show_post_gallery_metabox( $post ) {

wp_nonce_field( \'mytheme_post_gallery_metabox\', \'_mytheme_post_gallery_metabox\' );
$gallery = get_post_meta( $post->ID, \'_mytheme_post_gallery\', true );

?>
<a class="gallery-add button media-button button-primary button-large media-button-select" href="#" data-uploader-title="<?php _e( \'Add gallery images\', \'mytheme\' ); ?>" data-uploader-button-text="<?php _e( \'Add gallery images\', \'mytheme\' ); ?>"><?php _e( \'Add gallery images\', \'mytheme\' ); ?></a>
<table>
  <tr>
    <td>
      <ul id="gallery-metabox-list">
        <?php if ( $gallery ) : ?>
          <?php foreach ( $gallery as $key => $value ) : $image = wp_get_attachment_image_src( $value ); ?>
            <li>
              <input type="hidden" name="_mytheme_post_gallery[<?php echo $key; ?>]" value="<?php echo $value; ?>">
              <img class="image-preview" src="<?php echo $image[0]; ?>">
              <a class="change-image" href="#"><?php _e( \'Change | \', \'mytheme\' ); ?></a>
              <a class="remove-image" href="#"><?php _e( \'Remove\', \'mytheme\' ); ?></a>
            </li>
          <?php endforeach; ?>
        <?php endif; ?>
      </ul>
    </td>
  </tr>
</table>
<?php
}

此代码允许我通过metabox将图像添加到我的库中。我现在也在尝试获取每个图像的标题。我已经尝试了很多方法，但到目前为止运气不好。。任何想法都将不胜感激。

$thumb_img = get_post( get_post_thumbnail_id() ); // Get post by ID

echo $thumb_img->post_excerpt; // Display Caption

echo $thumb_img->post_content; // Display Description

<?php if($gallery) : ?>
    <?php foreach($gallery as $key => $value) :
        $image = wp_get_attachment_image_src($value);
        $image_post = get_post($value);
        $caption = $image_post->post_excerpt;

<p class="wp-caption-text"><?php echo $caption; ?></p>

[caption]<image> Caption[/caption]
