我使用图片附件页面逐个显示附加到帖子的图片,以幻灯片形式表示影响。我希望能够显示附加到父帖子的图像总数以及在任何给定附件页面上显示的特定图像的编号,以便您看到图片和单词“Image 3 of 15 “例如。

更新... 我能够使用此代码获取要显示的总数:

<?php 
  global $post;
  $attachments = get_children( array( 'post_parent' => $post->post_parent, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => 'ASC', 'orderby' => 'menu_order ID' ) );
  $count = count( $attachments );
  echo $count; 
?>

我仍然无法弄清楚如何显示当前图像的数量 有人有什么建议吗?

更新2 ...

格林妮的回答让我几乎到了,但它一次输出所有数字:

  

“图像1 of 8Image 2 of 8Image 3 of   8图像4 of 8图像5的8图像6   8图像7 of 8图像8 of 8“

以下是我使用的代码:

global $post;
$attachments = get_children( array( 'post_parent' => $post->post_parent, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => 'ASC', 'orderby' => 'menu_order ID' ) );
$count = count( $attachments );
$currentImage = 1;
foreach ($attachments as $attachment) {
   // output your image here
   echo "Image ". $currentImage . " of ". $count; 
   $currentImage++; 
}

出了什么问题?

更新3 - 答案!

global $post;
$attachments = get_children( array( 'post_parent' => $post->post_parent, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => 'ASC', 'orderby' => 'menu_order ID' ) );

$count = count( $attachments );
$specific = array();
$i = 1;

foreach ( $attachments as $attachment ) {
    $specific[$attachment->ID] = $i;
    ++$i;
}

echo "Image {$specific[$post->ID]} of {$count}";

这有效:

global $post;
$attachments = get_children( array( 'post_parent' => $post->post_parent, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => 'ASC', 'orderby' => 'menu_order ID' ) );

$count = count( $attachments );
$specific = array();
$i = 1;

foreach ( $attachments as $attachment ) {
    $specific[$attachment->ID] = $i;
    ++$i;
}

echo "Image {$specific[$post->ID]} of {$count}";

在上面的代码中添加如下内容:

$currentImage = 1;
foreach ($attachments as $attachment) {
   // output your image here
   echo "Image ". $currentImage . " of ". $count; 
   $currentImage++; 
}

如果您正在寻找管理图片库的插件,可以使用attachments插件,

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

它使图库保持独立,并且不会将图片库短代码放在帖子内容中,从而使您可以在帖子/页面/自定义帖子中完全保留图像显示。您也可以通过拖放

更改图像的顺序

这是一个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; ?>
