我正在处理一个自定义模板文件，该文件可以提取媒体库中具有特定标记的所有图像。我在社区的帮助下完成了这项工作，它还显示了与图像相关的帖子的标题。我需要拉标签后，图像作为类名附加到容器上。这是我的代码：

<?php
    $args = array(
        \'post_type\' => \'attachment\',
        \'posts_per_page\' => -1,
        \'post_status\' => \'any\',
        \'post_parent\' => null,
        \'tax_query\' => array(
            array(
                \'taxonomy\' => \'post_tag\',
                \'field\' => \'slug\',
                \'terms\' => \'logo\'
            )
        )
    );

$images = get_posts( $args );
if ( $images ) {
    foreach ( $images as $image ) {
        // Get the parent post ID
        $parent_id = $image->post_parent;
        // Get the parent post Title
        $parent_title = get_the_title( $parent_id );
        // Get the parent post permalink
        $parent_permalink = get_permalink( $parent_id );
        // Get image caption

        $logoimg = wp_get_attachment_image( $image->ID, \'Work Gallery\' );

        $posttags = get_the_tags();
            if ($posttags) {
                foreach ($posttags as $tag) {
                    str_replace(\'-\',\'_\',$tag->slug . \' \');
                }
            }

            echo \'<aside class="work_item" data-id="id-\' . get_the_ID() . \'" data-type="\' . $posttags . \'">\';

                echo \'<ul>\';

                            echo $logoimg;

                        echo \'</div>\';

                        echo \'<ul class="work_meta">\';

                            echo \'<li class="work_title">\';

                                echo \' \' . $parent_title . \' \';

                            echo \'</li>\';

                            echo \'<li class="work_item_content">\';

                                echo \' \' . get_post( get_post_thumbnail_id($post->ID) )->post_excerpt . \' \';

                            echo \'</li>\';

                        echo \'</ul>\';

                        echo \'<ul class="work_features">\';

                            echo \'<li class="lightbox">\';

                                $attachment_id = $post->ID; // dynamic attachment ID
                                $image_attributes = wp_get_attachment_image_src( $attachment_id, \'full\' ); // returns an array

                                echo \'<a class="work_lb tooltip" data-id="\' . get_the_ID() . \'" title="view in lightbox" href="\' . $image_attributes[3] . \'" rel="prettyPhoto[mixed]">\';

                                    echo \'Lightbox\';

                                echo \'</a>\';

                            echo \'</li>\';

                        echo \'</ul>\';

                    echo \'</li>\';

                echo \'</ul>\';

            echo \'</aside>\';

        }
        wp_reset_postdata();
    }
?>

data-type="<?php $posttags = get_the_tags(); if ($posttags) { foreach ($posttags as $tag) { echo str_replace(\'-\',\'_\',$tag->slug . \' \'); } } ?> <?php $posttags = get_the_terms($post->ID, \'type\'); if ($posttags) { foreach($posttags as $tag) { echo str_replace(\'-\',\'_\',$tag->slug . \'\'); } } ?>"
