如何用PHP判断 循环div里的 id 值是否为空,如果不是空则正常显示这个div层,如果为空则隐藏?
下面的代码是我的代码。
不知道用PHP来判断效率高还是用JQ判断效率高。
<code>//To try without API key: $video_list = json_decode(file_get_contents('')); $video_list = json_decode(file_get_contents('https://www.googleapis.com/youtube/v3/search?order=date&part=snippet&channelId='.$channelId.'&maxResults='.$maxResults.'&key='.$API_key.'')); foreach($video_list->items as $item) { //Embed video if(isset($item->id->videoId)){ echo '<div id="'. $item->id->videoId .'" class="xl12 xs6 xm4 xb3 video-box"> <div class="media box-shadow padding-bottom video-box-inr clearfix"> <a href="./video.php?v='.%20%24item->id->videoId%20.'" target="_blank" title="'. $item->snippet->title .'"><img src="./thumbnail.php?vid='.%20%24item->id->videoId%20.'" class="radius img-responsive" alt="'. $item->snippet->title .'"></a> <h6 id="strong-a-href-video-php-v-item-gt-id-gt-videoId-item-gt-snippet-gt-title-a-strong"><strong><a href="./video.php?v='.%20%24item->id->videoId%20.'">'. $item->snippet->title .'</a></strong></h6> </div> </div> '; } //Embed playlist else if(isset($item->id->playlistId)) { echo '<div id="'. $item->id->videoId .'" class="xl12 xs6 xm4 xb3 video-box"> <div class="media box-shadow padding-bottom video-box-inr clearfix"> <a href="./video.php?v='.%20%24item->id->videoId%20.'" target="_blank" title="'. $item->snippet->title .'"><img src="./thumbnail.php?vid='.%20%24item->id->videoId%20.'" class="radius img-responsive" alt="'. $item->snippet->title .'"></a> <h6 id="strong-a-href-video-php-v-item-gt-id-gt-videoId-item-gt-snippet-gt-title-a-strong"><strong><a href="./video.php?v='.%20%24item->id->videoId%20.'">'. $item->snippet->title .'</a></strong></h6> </div> </div> '; } }</code>
下面这段代码是视频列表的父div,id="这里获取视频的key ID号,"
//内部Html
因为是移步采集国外网站的视频,所以有时候获取不到视频的key ID,所以就无法加载。
怎么修改上面的代码实现,判断

直接用CSS
<code>DIV[id=""] { display: none; }</code>
WEB -> JS . SERVER -> PHP.
这个API获得json。难道数据不完整吗? 其中会有数据的id为空?好奇怪吧。
