image - Wordpress 获取图片 url（目前使用 wp_get_attachment_url）

Question

在 wordpress 中获取图片附件 url 有点麻烦。到目前为止，这是我的代码：

<?php // find images attached to this post / page.
            global $post;
            $thumb_ID = get_post_thumbnail_id( $post->ID );
            $args = array(
                'post_type' => 'attachment',
                'post_mime_type' => 'image',
                'numberposts' => -1,
                'orderby' => 'menu_order',
                'order' => 'ASC',
                'exclude' => $thumb_ID,
                'post_parent' => $post->ID
            );
            $images = get_posts($args);
            ?>

            <?php // Loop through the images and show them

            if($images)
            {
            foreach($images as $image)  
            {

            echo  wp_get_attachment_image_url($image->ID, $size='attached-image');

            }
            }

?>

什么都不返回。如果我换掉这个wp_get_attachment_image_url($image->ID, $size='attached-image');工作wp_get_attachment_image($image->ID, $size='attached-image');正常，但会带来图像而不仅仅是 url。

The following code will loop through all image attachments and output the src url. Note that there are two methods shown, depending on your need.

<?php

    global $post;
    $args = array( 'post_type' => 'attachment', 'numberposts' => -1, 'post_mime_type' => 'image', 'post_status' => null, 'post_parent' => $post->ID ); 
    $attachments = get_posts($args);
    if ($attachments) {
            foreach ( $attachments as $attachment ) {
                    // Method #1: Allows you to define the image size
                    $src = wp_get_attachment_image_src( $attachment->ID, "attached-image");
                    if ($src) {echo $src[0];}
                    // Method #2: Would always return the "attached-image" size
                    echo $attachment->guid;
            }
    }

?>
