从Wordpress Gallery图像中获取图像标题

Question

<?php $loop = new WP_Query( array( 'post_type' => 'gallery', 
        'posts_per_page' => 100 ) 
            ); 
        while ( $loop->have_posts() ) : $loop->the_post(); ?>




    <?php if ( get_post_gallery() ) :


            /* Loop through all the image and output them one by one */
            foreach( $gallery['src'] as $src ) : ?>

                <img src="<?php echo $src; ?>" class="my-custom-class" alt="Gallery image" />
                <?php
            endforeach;
        endif;

 endwhile; wp_reset_query(); ?>

上面的代码从一个名为“多媒体资料”的自定义帖子中提取WordPress多媒体资料，然后存储并显示图像。是否有一种方法也可以将库的标题存储到变量中？

您可以使用以下代码从WordPress gallery获取图像标题。

<?php $loop = new WP_Query( array( 'post_type' => 'gallery', 
        'posts_per_page' => 100 ) 
            ); 
        while ( $loop->have_posts() ) : $loop->the_post();

        if ( $gallery = get_post_gallery( get_the_ID(), false ) ) :

            $img_ids = explode( ',', $gallery['ids'] );
            /* Loop through all the image and output them one by one */
            foreach( $gallery['src'] as $key => $src ) : ?>

                <img src="<?php echo $src; ?>" class="my-custom-class" alt="Gallery image" />
                <?php
                    $image_post = get_post( $img_ids[ $key ] ); ?>
                    <p class="wp-caption-text"><?php echo $image_post->post_excerpt; ?></p>

            <?php endforeach;
        endif;

 endwhile; wp_reset_postdata(); ?>
