文件提交页面既已生成,下面任务就很明确了:将提交的文件内容保存到服务器上。

下面我们用两种方法来实现这个功能:

1. 用 PHP 来保存:
我们先定义一个文件保存函数 fup() 它有两个参数:
     $filename: 文件内容
     $fname: 文件名(包含路径)
剩下的就是写一个循环将文件依次写入服务器。这里要简单说明一下:
PHP 对于上传文件的处理是这样的:如果提交的文件框我为 file0, 那么提交给 PHP 的文件内容保存在变量 $file0 中,而文件名则保存在 $file0_name 中。这样在这个循环中我要做的就是将提交页面提交的内容分解出来,实现过程请看下面的代码。

fileup.php
----------------------------------------------------------------------

    function fup($filename,$fname)
    {        If($filename != "none") {
                copy($filename,$fname);
                unlink($filename);  
            }
    }

    for($i=0;$i    {
        $ffnn="file".$i;
        $ffnnname=$ffnn."_name";
        $ffpath="path".$i;
         
        //print $$ffnn;
        print $$ffnnname;
        print "
";
         
        fup($$ffnn,$$ffpath.$$ffnnname); //"../www/test/tmp/"
    }
?>
----------------------------------------------------------------------

2. 用 PERL 来保存:
它们实现的原理完全一样,在此不多说,请看代码:

fileup.cgi(fileup.pl)
----------------------------------------------------------------------
#!/usr/bin/perl  

use CGI qw/:standard/;  

if ($ENV{'CONTENT_TYPE'} !~ /multipart/form-data/) {  
  print "Cache-Control: no-cachenPragma: no-cachen" .  
    "Content-Type: text/htmlnn" .  
    "Your web browser cannot upload files. Sorry.";  
  exit 0;  
}


$cntfile=param('cnt');
print header;  
print start_html;  
#print "Receiving Please wait....";

&g_head;

#$writed = '../www/test/tmp/';

for ($i=0;$i    $paramfile = 'file'.$i;
    $parampath='path'.$i;
     
    $writed=param($parampath);

    &upfile;
    &g_body;
}

&g_bott;

#
sub upfile
{
    $maxdata = 512000;  
#    $writed = '../www/test/tmp/';  


    $strRFname=reverse $xfile;
    $intIndex=index($strRFname,'\');
    $strNetFname=substr($strRFname,0,$intIndex);
    $strNetFname=scalar reverse $strNetFname;
     
     
    if((stat $xfile)[7]>$maxdata){  
        print "Status: 411 Size Not Allowedn" .  
            "Content-Type: text/htmlnAllow: POSTnn" .  
            "411 411 Size Not Allowed

You got big problem.  Try again.

n";  
        exit 0;  
    }  
     
     
    binmode $xfile;  
    use File::Copy;  
    copy($xfile,$writed.$strNetFname);  
}

sub g_head{
    print '';
    print '';
    print '';
    print '    ';
    print '    ';
    print '    ';
    print '';
}

sub g_body{
    print '';
    print '    ';
    print '    ';
    print '    ';
    print '';
}

sub g_bott{
    print '
文件上传结果(Upload Result)
SourceFile:DestFile:Upload
'.$xfile .''.$writed.$strNetFname.'OK!
';
}
