Question

我有这个代码来检索图库中图像的图像网址，它工作正常，但我无法弄清楚如何获取每个图像的标题。

我尝试了搜索，但我似乎无法将所有信息放在一起！关于我如何找回字幕的任何建议？

 function show_related_gallery_image_urls( $content ) {

    global $post;

    // Only do this on singular items
    if( ! is_singular() )
        return $content;

    // Make sure the post has a gallery in it
    if( ! has_shortcode( $post->post_content, 'gallery' ) )
        return $content;



    // Retrieve all galleries of this post
    $galleries = get_post_galleries_images( $post );

    $image_list = <<<END
                    <div class="side_bar">
            <div class="related">
                <h3>Related Images</h3>
END;

    // Loop through all galleries found
    foreach( $galleries as $gallery ) {

        // Loop through each image in each gallery
        foreach( $gallery as $image ) {

            $src = $image;

            $image_list .=  '<a href="' . $src . '" rel="' . get_the_title() . '">' 
                                . '<img src="' . $src .'" />' 
                            . '</a>';

        }

    }

    $image_list .= '</div></div>';

    // Append our image list to the content of our post
    $content .= $image_list;

    return $content;

 }
 add_filter( 'the_content', 'show_related_gallery_image_urls' );

我希望我能很好地解释自己！谢谢！

这还没有通过尝试来测试，我稍微清理了一些代码：

1）将前两个IF语句合并为1

2）使用get_post_gallery()（Codex）返回src和图片ID。我们使用图片ID来返回标题，如果需要，我们也可以获得更多描述。

3）删除了包含的Foreach语句，因为我的方法只返回1个库，而不是多个，所以不需要循环。

function show_related_gallery_image_urls( $content ) {
    global $post;

    // Only do this on singular items 
    if( ! is_singular() || !has_shortcode( $post->post_content, 'gallery' ) )
        return $content;

    // Retrieve all galleries of this post
    $galleries = get_post_gallery( $post, false );

    $image_list = <<<END
                    <div class="side_bar">
            <div class="related">
                <h3>Related Images</h3>
END;

    // Loop through each image in each gallery
    $i = 0; // Iterator
    foreach( $gallery['src'] as $src ) {
        $caption = wp_get_attachment($gallery['id'][$i])['caption'];

        $image_list .=  '<a href="' . $src . '" rel="' . get_the_title() . '">' 
                        . '<img src="' . $src .'" />'
                        . '<div class="caption">'
                            . $caption
                        . '</div>'
                    . '</a>';

        $i++; // Incremenet Interator
    }

    $image_list .= '</div></div>';

    // Append our image list to the content of our post
    $content .= $image_list;

    return $content;

 }
 add_filter( 'the_content', 'show_related_gallery_image_urls' );

function wp_get_attachment( $attachment_id ) {

    $attachment = get_post( $attachment_id );
    return array(
        'alt' => get_post_meta( $attachment->ID, '_wp_attachment_image_alt', true ),
        'caption' => $attachment->post_excerpt,
        'description' => $attachment->post_content,
        'href' => get_permalink( $attachment->ID ),
        'src' => $attachment->guid,
        'title' => $attachment->post_title
    );
}

在旁注中，有一个图库过滤功能，您可以在其中更改图库的显示方式post_gallery Filter，here's a question显示如何编辑图库。还有一个很棒的WordPress Stack Exchange，这可能对将来有所帮助！
