Php 自定义WordPress图库帖子格式

我的当前主题支持画廊帖子格式。Gallery格式从Gallery中获取所有图像并以幻灯片形式显示。我想能够添加标题和照片信用额度，以每一张图片的底部，因为它的信息随着它的变化而变化

当前库格式模板如下所示：

 <?php if ( has_post_format( 'gallery' ) ) : ?>

   <div class="gallery-post-format">
      <?php
      $galleries = get_post_gallery_images( $post );

      $output = '<ul class="gallery-images">';
      foreach ($galleries as $gallery) {
         $output .= '<li>' . '<img src="'. $gallery . '">' . '</li>';
      }
      $output .= '</ul>';

      echo $output;
      ?>
   </div>

<?php endif; ?>

我想添加以下代码来显示每个图像的标题和照片信用额度

    <div>
    <?php 
        $photographer_name = get_post_meta(get_post_thumbnail_id(), 'be_photographer_name', true);
        $photographer_url = get_post_meta(get_post_thumbnail_id(), 'be_photographer_url', true);

        if ( $photographer_name ) : ?>
            <div id="tgg_credit_line" class="tgg-photo-credit" align="right">
                &#x1F4F7; Image Credit /
                <?php if ( $photographer_url ) : ?> 
                <a href="<?php echo $photographer_url ?>">
                <?php endif; ?>
            <?php echo $photographer_name ?>
                <?php if ( $photographer_url ) : ?> 
                </a>
                <?php endif; ?>
            </div>
        <?php endif; ?>
</div>
<div id="tgg_image_caption" class="tgg-image-caption" align="left">
    <?php echo get_post(get_post_thumbnail_id())->post_excerpt; ?>
</div>

</div>

我该怎么做？

这个怎么样：

<?php if ( has_post_format( 'gallery' ) ) : ?>

    <div class="gallery-post-format">
        <?php
            $gallery = get_post_gallery( $post, false );
            $att_ids = wp_parse_id_list( $gallery['ids'] );

            $output = '<ul class="gallery-images">';
            for ( $i = 0; $i < count( $gallery['src'] ); $i++ ) {
                $att_id = $att_ids[ $i ];
                $photographer_name = get_post_meta( $att_id, 'be_photographer_name', true );
                $photographer_url = get_post_meta( $att_id, 'be_photographer_url', true );

                $image = sprintf( '<img src="%s" />',
                    esc_url( $gallery['src'][ $i ] ) );

                $caption = '<div>';
                if ( $photographer_name ) {
                    $caption .= '<div class="tgg-photo-credit" align="right">';
                    $caption .= '&#x1F4F7; Image Credit /';
                    if ( $photographer_url ) {
                        $caption .= sprintf( '<a href="%s">%s</a>',
                            esc_url( $photographer_url ), esc_html( $photographer_name ) );
                    } else {
                        $caption .= esc_html( $photographer_name );
                    }
                    $caption .= '</div><!-- .tgg-photo-credit -->';
                }
                $caption .= '</div>';

                $excerpt = get_post_field( 'post_excerpt', $att_id );
                if ( $excerpt ) {
                    $caption .= /* wrapped */
                    '<div class="tgg-image-caption" align="left">' .
                        $excerpt .
                    '</div><!-- .tgg-image-caption -->';
                }

                $output .= '<li>' . $image . $caption . '</li>';
            }
            $output .= '</ul><!-- .gallery-images -->';

            echo $output;
        ?>
    </div><!-- gallery-post-format -->

<?php endif; ?>

谢谢你，莎莉。如何获取📷；图像信用/显示在摄影师姓名前？还有，我怎样才能让摄影师的名字向右对齐，标题向左对齐？我刚刚意识到，当使用gallery post格式时，它会创建一个与特色图像分离的幻灯片。因此，我不希望特色图片出现在单个帖子上，但我仍然需要将其附加到帖子上，以便在主页上显示为缩略图。我怎么能用这个代码做到呢？我已经更新了代码。尝试一下（第一个或第二个版本）并让我知道。作为对您第二条评论的回复，我认为这涉及到修改

single.php

模板。您能否在上共享模板内容/代码并共享其URL？或者如果你不介意的话，告诉我你实际使用的主题的名称。（或者父主题的名称，如果您使用的是子主题。）我使用的是colormag的自定义子主题
