使用JW Player 6在PHP和MySQL中执行JavaScript一次循环

问题描述：

I'm using JWPlayer6 (non-commercial version) and I'm facing a serious problem, using a while loop to loop over all videos from a MySQL database using PHP. Unfortunately, the web page just shows one video from MySQL. When I checked the code in Chrome, I saw that inside the <div id='my-video'></div>, there's nothing to show. How should I fix the problem?

<?php
$result = mysql_query("SELECT * FROM schoolvideo GROUP BY folderName ORDER BY id desc");
while($data = mysql_fetch_array($result)) {
  $id = $data['id'];
  $video = $data['video'];
  $folderName = $data['folderName'];
?>
<div class="square">
  <div id='my-video'></div>
  <script type="text/javascript">
  jwplayer('my-video').setup({
    file: 'http://abc.com/video/<?php echo $folderName; ?>/<?php echo $video; ?>',
    width: '370',
    height: '270',
    primary: 'flash',
    image: 'http://abc.com/img/poster.png',
    autostart: false
  });
  </script>
</div>
<?php
}
?>

我正在使用JWPlayer6（非商业版），我正面临一个严重的问题，使用while循环使用PHP循环来自MySQL数据库的所有视频。不幸的是，该网页只显示了一个来自MySQL的视频。当我在Chrome中检查代码时，我在＆lt; div id ='my-video'＆gt;＆lt; / div＆gt; code>中看到了这一点，没有什么可以显示的。我该如何解决这个问题呢？ p>

 ＆lt;？php 
 $ result = mysql_query（“SELECT * FROM schoolvideo GROUP BY folderName ORDER BY id desc”）; 
while（  $ data = mysql_fetch_array（$ result））{
 $ id = $ data ['id']; 
 $ video = $ data ['video']; 
 $ folderName = $ data ['folderName']; \  n？＆gt; 
＆lt; div class =“square”＆gt; 
＆lt; div id ='my-video'＆gt;＆lt; / div＆gt; 
＆lt; script type =“text / javascript”＆gt; 
  jwplayer（'my-video'）。setup（{
 file：'http://abc.com/video/<?php echo $ folderName;？＆gt; /＆lt;？php echo $ video;？＆gt;  '，
宽度：'370'，
高度：'270'，
主要：'flash'，
图像：'http：//abc.com/img/poster.png'，
自动启动：  false 
}）; 
＆lt; / script＆gt; 
＆lt; / div＆gt; 
＆lt;？php 
} 
？＆gt; 
  code>  pre> 
  div>

答

Your loop will generate multiple divs with the same id "my-video". You should make them unique.

<div id='my-video-<?php echo $id ?>'></div>
...
jwplayer('my-video-<?php echo $id ?>').setup({...
