Wordpress:查询posts媒体库中的所有图像

在wordpress术语中,您上传到特定帖子的每个图像都称为附件。 要列出所有附件,可以使用 get_children() 功能:

$images =& get_children( 'post_type=attachment&post_mime_type=image&post_parent=10' );

$counter=0;
foreach( (array) $images as $attachment_id => $attachment )
{
   $counter++;
   echo "<a href='".wp_get_attachment_link( $attachment_id ) . "'>image $counter</a><br />";
}

如果您正在寻找一个插件来管理图像库,您可以使用 attachments 插件,

http://wordpress.org/plugins/attachments/

下面是如何检索图库图像的示例代码,

<?php $attachments = new Attachments( 'attachments' ); /* pass the instance name */ ?>
<?php if( $attachments->exist() ) : ?>
  <h3>Attachments</h3>
  <p>Total Attachments: <?php echo $attachments->total(); ?></p>
  <ul>
    <?php while( $attachments->get() ) : ?>
      <li>
        ID: <?php echo $attachments->id(); ?><br />
        Type: <?php echo $attachments->type(); ?><br />
        Subtype: <?php echo $attachments->subtype(); ?><br />
        URL: <?php echo $attachments->url(); ?><br />
        Image: <?php echo $attachments->image( 'thumbnail' ); ?><br />
        Source: <?php echo $attachments->src( 'full' ); ?><br />
        Size: <?php echo $attachments->filesize(); ?><br />
        Title Field: <?php echo $attachments->field( 'title' ); ?><br />
        Caption Field: <?php echo $attachments->field( 'caption' ); ?>
      </li>
    <?php endwhile; ?>
  </ul>
<?php endif; ?>
