高分求高手来看看上传问题

[haihao_110]

我想上传文件时在备份一个文件 备份的文件名为上传文件名+上传人姓名+上传时间 ，
都不是汉字啊这是我的代码高手们帮帮看看，为什么报错

<form enctype="multipart/form-data" action="" method="post">
<table width="400" border="0" cellspacing="1" cellpadding="1" align="center" bgcolor="#E6E6E6" >
    <tr> 
      <td height="22" align="center" valign="middle" bgcolor="#F5F5F5" width="400"> 文件上传      </td>
    </tr>
    <tr align="center" valign="middle"> 
      <td align="center"  height="80" width="400" bgcolor="#FFFFFF"> 
	  选择文件:<input type="file" name="upload_file"  style="width:300">
	</td>		
    </tr>
    <tr align="center" valign="middle"> 
      <td bgcolor="#F5F5F5" height="24" width="400"> 
	    <div align="center">
          <input type="submit"  value="开始上传">
      </div></td>
    </tr>
  </table>
</form>

//$uploadFileName = $_POST['test'];
$ext = '.txt';
if(strrpos(@$_FILES['upload_file']['name'],'.') !== false){
    $ext = substr( @$_FILES['upload_file']['name'], strrpos(@$_FILES['upload_file']['name'], '.' ));
}
if(strtolower($ext) != '.txt' 
    && strtolower($ext) != '.jpg'
    && strtolower($ext) != '.gif' 
    && strtolower($ext) != '.png'
    && strtolower($ext) != '.doc'){
    echo '上传的文件类型不符合要求';
    exit;
}

$fileName = "E:\site_data/".'/'.date('Ymd').'/'.time().rand(100,999).$ext;            
move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$_SERVER['DOCUMENT_ROOT'].'/'.$fileName);//这行报错
//
//$uploadfile="E:\site_data/".$_FILES['upload_file']['name'];
//if(move_uploaded_file($_FILES['upload_file']['tmp_name'],$uploadfile)){
//echo "成功";}

'D:/APMServ5.2.6/www/htdocs/E:\site_data//20100730/1280453764180.txt' in D:\APMServ5.2.6\www\htdocs\shangchuan.php on line 36
怎么改啊！！！！

[kyzy_yy_pm]

$upload_dir="./bak_data/";
$upload_bak="./site_data/";

$file=$_FILES['upload'];
$username=$_POST['upname'];


$ext = explode(".",$file['name']);
$ext = $ext[count($ext)-1];  
$filename1 = substr($file['name'],0,(strlen($file['name'])-strlen($ext)-1));              
$bakfilename = "{$username}_{$uid}_".date("Y_m_d_H_i_s").".{$ext}";
if(move_uploaded_file($file['tmp_name'],$upload_dir.$file['name'])){
	copy($upload_bak.$file['name'], $upload_bak.$file['name'].'_'.$bakfilename); 
	echo "上传成功";
}

[kyzy_yy_pm]

copy($upload_bak.$file['name'], $upload_dir.$file['name'].'_'.$bakfilename);

[kyzy_yy_pm]

按楼主的想法的话$upload_bak根本没用，迷惑人

[haihao_110]

[Quote=引用 24 楼 kyzy_yy_pm 的回复:]
PHP code
$upload_dir="./bak_data/";
$upload_bak="./site_data/";

$file=$_FILES['upload'];
$username=$_POST['upname'];


$ext = explode(".",$file['name']);
$ext = $ext[count($ext)-1];
$file……

你这样写又报错了Warning: copy(./site_data/PHP对数据库的操作.txt) [function.copy]: failed to open stream: No such file or directory in D:\APMServ5.2.6\www\htdocs\shangchuan.php on line 52
就是这句copy($upload_bak.$file['name'], $upload_bak.$file['name'].'_'.$bakfilename);

[kyzy_yy_pm]

copy($upload_dir.$file['name'], $upload_dir.$file['name'].'_'.$bakfilename);

失误，楼主改下

[haihao_110]

你这样写还是报错 ，不过谢谢你，问题我已经解决了，结贴给分了

[kyzy_yy_pm]

说说怎么回事

[haihao_110]

这是最后调好的

$filename1 = substr($file['name'],0,(strlen($file['name'])-strlen($ext)-1));              
$bakfilename = $filename1."_{$uid}_{$username}_".date("Y_m_d_H_i_s").".{$ext}";
if(move_uploaded_file($file['tmp_name'],$upload_bak.$file['name'])){
copy($upload_bak.$file['name'], $upload_bak.$bakfilename); 
echo "上传成功";

[xuzuning]

既然你有
$fileName = "E:/site_data/".'/'.date('Ymd').'/'.time().rand(100,999).$ext;
那么就不需要而外指明路径了
move_uploaded_file(@$_FILES['upload_file']['tmp_name'], $fileName);

[程序猿之殇]

$_SERVER['DOCUMENT_ROOT'] = 'D:/APMServ5.2.6/www/htdocs
$fileName你又给"E:\site_data/".'/'.date('Ymd').'/'.time().rand(100,999).$ext;传值了

两个构造在一起,肯定是不存在的路径了.

$fileName = date('Ymd').'/'.time().rand(100,999).$ext;            
move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$_SERVER['DOCUMENT_ROOT'].'/'.$fileName);
@copy($_SERVER['DOCUMENT_ROOT'].'/'.$fileName, "E:\site_data/".'/'.$fileName);

[haihao_110]

谢谢大家 但还是报错说failed to open stream: No such file or directory in D:\APMServ5.2.6\www\htdocs\shangchuan.php on line 38

//$uploadFileName = $_POST['test'];
$ext = '.txt';
if(strrpos(@$_FILES['upload_file']['name'],'.') !== false){
    $ext = substr( @$_FILES['upload_file']['name'], strrpos(@$_FILES['upload_file']['name'], '.' ));
}
if(strtolower($ext) != '.txt' 
    && strtolower($ext) != '.jpg'
    && strtolower($ext) != '.gif' 
    && strtolower($ext) != '.htm'
    && strtolower($ext) != '.doc'){
    echo '上传的文件类型不符合要求';
    exit;
}

//$fileName = "E:\site_data/".'/'.date('Ymd').'/'.time().rand(100,999).$ext;            
//move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$fileName);
$fileName = date('Ymd').'/'.time().rand(100,999).$ext;            
move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$_SERVER['DOCUMENT_ROOT'].'/'.$fileName);//就是这行
@copy($_SERVER['DOCUMENT_ROOT'].'/'.$fileName, "E:\site_data/".'/'.$fileName);

我想让上传文件保存到E:\site_data/中

[xuzuning]

你是越改越乱了！
$fileName = "E:/site_data/".date('Ymd').'/'.time().rand(100,999).$ext;
你需要保证相应的目录存在并可写
比如今天
E:/site_data/20100730
明天
E:/site_data/20100731

[haihao_110]

感谢楼上的提示但是我改过后 不报错 但是上传文件后在 E:\site_data/文件夹中没有我上传的文件

$fileName = "E:\site_data/".'/'.date('Ymd').'/'.time().rand(100,999).$ext;            
//move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$fileName);
//$fileName = date('Ymd').'/'.time().rand(100,999).$ext;            
move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$fileName);
@copy($_SERVER['DOCUMENT_ROOT'].'/'.$fileName, "E:\site_data/".'/'.$fileName);

感谢大侠们赐教

[jianglin28290]

$fileName = "E:/site_data/".'/'.date('Ymd').'/'.time().rand(100,999).$ext;
人家已经写的很清楚了，\在php里是转义，就算你要用在路径上，至少也要加两个吧

[CunningBoy]

<?php
$fileName = date('Ymd').'/'.time().rand(100,999).$ext;
$base_folder = "E:/site_data/";       
move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$base_folder.$fileName);
?>

我之前也这样写过但是也是没有效果

$ext = '.txt';
if(strrpos(@$_FILES['upload_file']['name'],'.') !== false){
$ext = substr( @$_FILES['upload_file']['name'], strrpos(@$_FILES['upload_file']['name'], '.' ));
}
if(strtolower($ext) != '.txt' 
    && strtolower($ext) != '.jpg'
    && strtolower($ext) != '.gif' 
    && strtolower($ext) != '.htm'
    && strtolower($ext) != '.doc'){
    echo '上传的文件类型不符合要求';
    exit;
}
$fileName = date('Ymd').'/'.time().rand(100,999).$ext;
$base_folder = "E:/site_data/";       
if(move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$base_folder.$fileName)){
echo "成功";}

[haihao_110]

上传成功了 但是备份文件的文件名没有上传人的名字 只有时间 大侠们帮我看看吧

$upload_dir=="./site_data/";
$upload_bak="./site_data/";

$file=$_FILES['upload'];

$ext = explode(".",$file['name']);
$ext = $ext[count($ext)-1];  
$filename1 = substr($file['name'],0,(strlen($file['name'])-strlen($ext)-1));              
$bakfilename = "{$username}_{$uid}_".date("Y_m_d_H_i_s").".{$ext}";
if(move_uploaded_file($file['tmp_name'],$upload_bak.$file['name'])){
copy($upload_bak.$file['name'], $upload_bak.$bakfilename); 
}

[Alfredknox]

帮顶，接分。。。

[Dleno]

$upload_dir=="./site_data/";
$upload_bak="./site_data/";
//你至少要对$username赋予值.
$username = $_POST['username'];//提交过来的名字
//或者$username = $_COOKIE['username'];//cookie里的名字
$file=$_FILES['upload'];

$ext = explode(".",$file['name']);
$ext = $ext[count($ext)-1];
$filename1 = substr($file['name'],0,(strlen($file['name'])-strlen($ext)-1));
$bakfilename = "{$username}_".date("Y_m_d_H_i_s").".{$ext}";
if(move_uploaded_file($file['tmp_name'],$upload_bak.$file['name'])){
copy($upload_bak.$file['name'], $upload_bak.$bakfilename);
}
