我有一個HTML表我從數據庫建立:PHP函數調用弄亂表

<tr onclick="DoNav('<?php echo $result_videos[$i]["video_url"]; ?>');"> 
    <td> 
     <?php echo $result_videos[$i]["camera_name"]; ?> 
    </td> 
    <td> 
     Timezone: <?php echo queryTimezone(); ?> <br> 
     Video Size: <?php echo $result_videos[$i]["video_size"]; ?> bytes <br> 
      Video Length: <?php echo strTime($result_videos[$i]["video_length"]); ?> 
    </td> 
    <td> 
     <form name="myform" action="<?php echo htmlentities($_SERVER['REQUEST_URI']); ?>" method="POST"> 
     <input type="submit" name="delete_video" value="Delete" title="Delete this video" onClick="return confirm('Are you sure you want to delete?')"/> 
     <input type="hidden" name="video_url" value="<?php echo $result_videos[$i]["video_url"]; ?>" /> 
     </form> 
    </td> 
</tr> 

問題是這樣的功能:

function queryTimezone() 
{ 
$query = "SELECT timezone FROM #__camcloud_users WHERE user_id=".$user->id; 
$db->setQuery($query); 
$timezone = $db->loadResult(); 
return $timezone; 
} 

它攪亂表了。我似乎沒有得到任何PHP錯誤,並切斷了「時區:」部分的表格,並將其引至頁面的右上角。基本上我稱之爲功能queryTimezone。如果我改變把它放在html表格中它工作正常:

<tr onclick="DoNav('<?php echo $result_videos[$i]["video_url"]; ?>');"> 
    <td> 
     <?php echo $result_videos[$i]["camera_name"]; ?> 
    </td> 
    <td> 
     Timezone: <?php 
$query = "SELECT timezone FROM #__camcloud_users WHERE user_id=".$user->id; 
$db->setQuery($query); 
$timezone = $db->loadResult(); 
echo $timezone; 
?> <br> 
     Video Size: <?php echo $result_videos[$i]["video_size"]; ?> bytes <br> 
      Video Length: <?php echo strTime($result_videos[$i]["video_length"]); ?> 
    </td> 
    <td> 
     <form name="myform" action="<?php echo htmlentities($_SERVER['REQUEST_URI']); ?>" method="POST"> 
     <input type="submit" name="delete_video" value="Delete" title="Delete this video" onClick="return confirm('Are you sure you want to delete?')"/> 
     <input type="hidden" name="video_url" value="<?php echo $result_videos[$i]["video_url"]; ?>" /> 
     </form> 
    </td> 
</tr> 

這工作正常。我是如何稱呼功能的?

功能無法確定$用戶> ID,因此犯規返回一個有效的結果... theres沒什麼的功能,它定義了$ USER是

+0

ack,謝謝。我錯誤地認爲,因爲我有'$ user =&JFactory :: getUser();'和'$ db =&JFactory :: getDBO();'全局設置它可以工作......感嘆,我有更多要學習。 – Tom 2012-01-01 21:47:54

使用他的函數聲明,而不是:

function queryTimezone($user,$db) 
{ 
    $query = "SELECT timezone FROM #__camcloud_users WHERE user_id=".$user->id; 
    $db->setQuery($query); 
$timezone = $db->loadResult(); 
return $timezone; 
} 

這樣稱呼:

Timezone: <?php echo queryTimezone($user,$db); ?> <br>
