Jesper,看起来类型图像字段仅存储图像 URL,而不是其内容。如果您想检索一些其他信息(例如标题、标题和描述),您可能必须尝试通过其 URL 获取图像 ID。在你的functions.php中:
/**
* Retrieve the attachment ID from its URL
*
* @param string $image_url
* @return int $attachment[0] The attachment ID
*
* @link http://pippinsplugins.com/retrieve-attachment-id-from-image-url/
*/
function mytheme_get_attachment_id( $image_url ) {
global $wpdb;
$prefix = $wpdb->prefix;
$attachment = $wpdb->get_col( $wpdb->prepare( "SELECT ID FROM " . $prefix . "posts" . " WHERE guid='%s';", $image_url ) );
return $attachment[0];
}
之后,您可以使用您foreach
并检查您的 ID:
<?php
$resortimages = get_post_meta(get_the_ID(), 'wpcf-r-images');
foreach ($resortimages as $resortimage) {
// Get attachment ID by its URL
if ( $resortid = mytheme_get_attachment_id( $resortimage ) )
$resortname = get_the_title($resortid);
echo '<li><a href="'. $resortimage. '" rel="lightbox" title="' . $resorttitle . ' ><img src="'. $resortimage. '"/></a></li>';
}
?>
但请注意您将执行的查询数量。希望能帮助到你!
