我正在使用ACF插件创建静态（非电子商务）产品页面。

我现在正在制作一个页面，其中列出了所有带有产品名称的子页面，以及添加到product_徽标自定义字段中的图像。我发现一些代码几乎可以实现我想要的一切：

                <?php
                //get children of page 241 and display with custom fields

                $args=array(
                  \'post_parent\' => 825,
                  \'post_type\' => \'page\',
                );
                $my_query = null;
                $my_query = new WP_Query($args);
                if( $my_query->have_posts() ) {

                  while ($my_query->have_posts()) : $my_query->the_post(); ?>
                        <div>
                            <a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?>

                                <!-- here I get the \'product_short_description\' custom field\'s data, assign it to the $meta_one variable and echo it out !-->
                                <?php $meta_one = get_post_meta($post->ID, \'product_short_description\', true); ?>
                                <span><?php echo $meta_one; ?></span>

                                <!-- here I get the \'product_logo\' custom field\'s data, assign it to the $meta_two variable and echo it out !-->
                                <?php $meta_two = get_post_meta($post->ID, \'product_logo\', true); ?>
                                <span><img src="<?php echo $meta_two; ?>" /></span>
                            </a>
                        </div>
                   <?php endwhile; } ?>
                <?php wp_reset_query();  // Restore global post data stomped by the_post().?>

第二个字段$meta\\u two获取包含图像ID的product\\u徽标字段。我想使用以下方法将其转换为URL：

  <?php wp_get_attachment_image_src($meta_two, null, true); ?>

但这只是给了我一个空白的URL。

完整代码如下：

                $args=array(
                  \'post_parent\' => 825,
                  \'post_type\' => \'page\',
                );
                $my_query = null;
                $my_query = new WP_Query($args);
                if( $my_query->have_posts() ) {

                  while ($my_query->have_posts()) : $my_query->the_post(); ?>
                        <div>
                            <a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?>

                                <!-- here I get the \'product_short_description\' custom field\'s data, assign it to the $meta_one variable and echo it out !-->
                                <?php $meta_one = get_post_meta($post->ID, \'product_short_description\', true); ?>
                                <span><?php echo $meta_one; ?></span>

                                <!-- here I get the \'product_logo\' custom field\'s data, assign it to the $meta_two variable and echo it out !-->
                                <?php $meta_two = get_post_meta($post->ID, \'product_logo\', true); ?>
                                <span><img src="<?php wp_get_attachment_image_src($meta_two, null, true); ?> " /></span>
                            </a>
                        </div>
                   <?php endwhile; } ?>
                <?php wp_reset_query();  // Restore global post data stomped by the_post().?>

有人能指出我做错了什么吗？

                    <?php
                    //get children of page 241 and display with custom fields

                    $args=array(
                      \'post_parent\' => 825,
                      \'post_type\' => \'page\',
                    );
                    $my_query = null;
                    $my_query = new WP_Query($args);
                    if( $my_query->have_posts() ) {

                      while ($my_query->have_posts()) : $my_query->the_post(); ?>
                            <?php $img = wp_get_attachment_image_src( get_post_meta($post->ID, \'product_logo\', true)); ?>
                            <?php $alt_text_for_logo = get_post_meta($post->ID, \'alt_text_for_logo\', true); ?>
                            <div class="column small-6 medium-4 product">
                                <a href="<?php the_permalink() ?>" title="<?php the_title_attribute(); ?>">
                                    <span> <img src="<?php echo $img[0]; ?>" alt="<?php echo $alt_text_for_logo; ?>" /></span>
                                    <h2><?php the_title(); ?></h2>
                                </a>
                            </div>
                       <?php endwhile; } ?>
                    <?php wp_reset_query();  // Restore global post data stomped by the_post().?>
            </div>
