wordpress 怎么设置一篇文章两个特色图片
wordpress 怎么设置一篇文章两个特色图片比如文章名称为：测试特色图片文章现在我想设置“测试特色图片文章”这篇文章特色图片默认只能设置一个特色图片我想让他有两个特色图片如：特色图片1
我有更好的答案
放二个DIV块，每个DIV块中使用一次调用缩略图的方法。
是同一篇文章两个不同的图片
这个我可是写不出来能调出第一张图，就能调出第二张图，只是我不会写这个代码了。你是这个世界上第一个有这想法的人，去努力实现吧。
要是调两个图片好办!要同一篇文章设置两个特色图片然后调用这篇文章的这两个特色图片

将下面的代码放到你主题的functions.php文件 ?& 之前：
/* 設定所有文章第一個為特色圖片開始*/
function autoset_featured_image(){
$already_has_thumb = has_post_thumbnail($post-&ID);
if (!$already_has_thumb){
$attached_image = get_children("post_parent=$post-&ID&post_type=attachment&post_mime_type=image&numberposts=1");
if ($attached_image){
foreach ($attached_image as $attachment_id =& $attachment) {
set_post_thumbnail($post-&ID, $attachment_id);
add_action('the_post', 'autoset_featured_image');
add_action('save_post', 'autoset_featured_image');
add_action('draft_to_publish', 'autoset_featured_image');
add_action('new_to_publish', 'autoset_featured_image');
add_action('pending_to_publish', 'autoset_featured_image');
add_action('future_to_publish', 'autoset_featured_image');

下面这个脚本能使生成一个大幅图片，并用该图片代替用户所上传的图片（如果所上传图片尺寸大于用户的后台设置），以节省服务器空间，如果你链接到的是原始图片的缩略图，还可以节省带宽，效果和lightbox插件一样。
只要将以下代码添加到functions.php文件并保存即可。
function replace_uploaded_image($image_data) { // if there is no large image : return if (!isset($image_data['sizes']['large'])) return $image_ // paths to the uploaded image and the large image $upload_dir = wp_upload_dir(); $uploaded_image_location = $upload_dir['basedir'] . '/' .$image_data['file']; $large_image_location = $upload_dir['path'] . '/'.$image_data['sizes']['large']['file']; // delete the uploaded image unlink($uploaded_image_location); // rename the large image rename($large_image_location,$uploaded_image_location); // update image metadata and return them $image_data['width'] = $image_data['sizes']['large']['width']; $image_data['height'] = $image_data['sizes']['large']['height']; unset($image_data['sizes']['large']); return $image_ } add_filter('wp_generate_attachment_metadata', 'replace_uploaded_image');
注意：不同主题对该代码的支持程度会有所不同
