我在删除正确的文件时遇到问题。我正在显示按上传时间排序的用户上传的文件列表(最后一次上传)。如果有3-4个文件的列表,无论我点击哪个文件删除,列表中的第一个文件都会被删除,最后上传的文件就是。这是我的页面,显示特定用户上传的文件。
<?php
$uid=$faculty_data['faculty_id']; //Assigns logged in id to a variable
$query="SELECT * FROM uploads ORDER BY datetime DESC"; //Sorts by date time
$result=mysql_query($query);
while($row=mysql_fetch_assoc($result))
{
if($uid==$row['faculty_id']) //Checks if the logged in id matches with id in DB
{
echo '<form action="delete.php" method="POST">';
echo "<strong>File: </strong>";
$url=$row['link'];
$new="http://tofsis.com/fileshare/".$url;
echo "<a href='$new'>$new</a><br/>";
echo "<strong>On: </strong>".$row['datetime'];
echo '<br><input type="submit" name="delete" class="btn btn" value="Delete File"/>';
echo '<hr>';
echo '</form>';
}
}
?>
这是我的删除页面:
<?php
$uid=$faculty_data['faculty_id'];
$query="SELECT * FROM uploads ORDER BY datetime DESC";
$result=mysql_query($query);
if(isset($_POST['delete']))
{
while($row=mysql_fetch_assoc($result))
{
if($uid==$row['faculty_id'])
{
$url=$row['link'];
$new="http://tofsis.com/fileshare/".$url;
$query="DELETE FROM uploads WHERE link = '$url'";
$result=mysql_query($query);
unlink($url);
}
}
header('Location: my_uploads.php');
exit();
}
else {
echo '<script type="text/javascript">alert("Oops something went wrong!")</script>';
header('Location: my_uploads.php');
exit();
}
?>
谁能告诉我哪里出错了,以便我可以解决我的问题?
