显示所有链接到文章的图片附件
下面这段代码可以将链接到文章的图片附件自动显示在文章中,不需要你手工编辑。
将代码添加到你的主题functions.php文件中:
- // display user-submitted images
- function usp_display_images() {
- global $post;
- $args = array(‘order’=>’ASC’, ‘post_type’=>’attachment’, ‘post_parent’=>$post->ID, ‘post_mime_type’=>’image’, ‘post_status’=>null);
- $items = get_posts($args); ?>
- <div class=“usp-image”>
- <?php foreach ($items as $item) {
- $atts = wp_get_attachment_image_src($item->ID, ‘medium’);
- $full = wp_get_attachment_image_src($item->ID, ‘full’); ?>
- <a href=“<?php echo $full[0]; ?>” target=“_blank”><img src=“<?php echo $atts[0]; ?>” width=“<?php echo $atts[1]; ?>” height=“<?php echo $atts[2]; ?>” alt=“”></a>
- <?php }
- $author = get_post_meta($post->ID, ‘user_submit_name’, true);
- $url = get_post_meta($post->ID, ‘user_submit_url’, true);
- if (filter_var($url, FILTER_VALIDATE_URL) !== false) {
- echo ‘<span class=“usp-author-link”>Posted by <a href=“‘ . $url . ‘”>’ . $author . ‘</a></span> ‘;
- } ?>
- </div>
- <?php }
- add_filter(‘the_content’, ‘usp_display_images’);
当然,还需另外的CSS样式及HTML代码配合图片显示。
