Question

当我加载所有文章的信息时，信息被加载但当我尝试分享它时会得到错误的标题，desc和img。

$allPost = Post::getAllPageList();
        if (count($allPost)) {
            $meta='';
            foreach ($allPost as $k => $v) {
                $post = new Post($v);
                $fileName = $post->getFirstPic($v);
                $meta .= "<meta property='og:title' content='".$post->getTitle()."' />";
                $meta .= "<meta property='og:description' content='".strip_tags(html_entity_decode($post->getText(),ENT_QUOTES,'UTF-8'))."' />";
                $meta .= "<meta property='og:image' content='http://lateevents.com/upload/Post/GalleryBig/$fileName' />";
            }
            echo $meta;
        }

当我试图通过文章过滤信息时，我失败了，Facebook就没有了。

CODE：

        $allPost = Post::getAllPageList();
        if (count($allPost)) {
            $meta='';
            foreach ($allPost as $k => $v) {
                if(isset($_GET['id']) && $_GET['id']!=$v)
                    continue;
                $post = new Post($v);
                $fileName = $post->getFirstPic($v);
                $meta .= "<meta property='og:title' content='".$post->getTitle()."' />";
                $meta .= "<meta property='og:description' content='".strip_tags(html_entity_decode($post->getText(),ENT_QUOTES,'UTF-8'))."' />";
                $meta .= "<meta property='og:image' content='http://lateevents.com/upload/Post/GalleryBig/$fileName' />";
            }
            echo $meta;
        }

信息是正确加载的，但facebook忽略了它。

有什么想法吗？

PS：我看到Facebook从here获得了什么。

问题在于

if（isset（$ _ GET ['id']）＆amp;＆amp; $ _GET ['id']！= $ v）

。出于某种原因，$_GET['id']应该分配给变量。

CODE

$allPost = Post::getAllPageList();
        if (count($allPost)) {
            $id=$_GET['id'];
            $meta='';
            foreach ($allPost as $k => $v) {
                if(isset($id) && $id!=$v)
                    continue;
                $post = new Post($v);
                $fileName = $post->getFirstPic($v);
                $meta .= "<meta property='og:title' content='".$post->getTitle()."' />";
                $meta .= "<meta property='og:description' content='".strip_tags(html_entity_decode($post->getText(),ENT_QUOTES,'UTF-8'))."' />";
                $meta .= "<meta property='og:image' content='http://lateevents.com/upload/Post/GalleryBig/$fileName' />";
            }
            echo $meta;
        }

Facebook分享尝试为不同的文章加载不同的描述
