警告:move_uploaded_file()无法打开流

Question

我想在ftp上传文件.

这是我的代码

    $jname= "Accounts of Biotechnology Research";
    if (!is_dir('/Trade/upload/ '.$jname)) {

        mkdir('/Trade/upload/ '.$jname);   // line 63
    }
    move_uploaded_file($_FILES["submission_file"]["tmp_name"],    "/Trade/upload/$jname/" . $dup_name );    // line 67

Trade是public_html文件夹中的一个文件夹.

当我上传文件时,它会给我一个警告,比如

Warning: mkdir() [function.mkdir]: No such file or directory in /home/my_username/public_html/Trade/upload.php on line 63

Warning: move_uploaded_file(/Trade/upload/Accounts of Biotechnology Research/76164762-sm.pdf) [function.move-uploaded-file]: failed to open stream: No such file or directory in /home/my_username/public_html/Trade/upload.php on line 67

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/phphZXp0O' to '/Trade/upload/Accounts of Biotechnology Research/76164762-sm.pdf' in /home/my_username/public_html/Trade/upload.php on line 67 

Answer 1

第一:你在这里有一个空间mkdir('/Trade/upload/ '.$jname);.假设你应该mkdir('/Trade/upload/'.$jname);(is_dir相同)

第二:确保您可以写入Trade/upload目录.

第三(我认为这是真正的问题):

看起来您正在尝试上传到具有完整路径的目录: /home/my_username/public_html/Trade/upload/,但您的代码将尝试创建具有完整路径的目录: /Trade/upload/.你需要改变

 if (!is_dir('/Trade/upload/ '.$jname)) {    
     mkdir('/Trade/upload/ '.$jname);   // line 63
 }

至

 if (!is_dir('upload/'.$jname)) {    
     mkdir('upload/'.$jname);   // line 63 (or maybe there should be Trade/upload, but suppose current working dir will be /home/my_username/public_html/Trade, so only upload/)
 }

另一种选择是强制mkdir以递归方式创建目录:

 mkdir('/Trade/upload/'.$jname, 0755, true);

但在这种情况下,文件将被上传到/Trade/upload/...而不是/home/my_username/public_html/Trade/upload/...
