下载提示输入ftp_get [英] Download prompt for ftp_get

问题描述

我目前正在实现一个系统，让用户从ftp下载文件而不需要ftp客户端。我已经开发了一个登录系统，并成功管理列出文件夹中的文件。但是，我打算使用ftp_get以另存为提示进行下载过程。

我提到 http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/PHP_Databases/ Q_23210157.html＃mainSection ，但所提出的解决方案并不确凿。

我确实使用了之前论坛主题中的一个建议，但我得到了一个msg执行ftp_get后出现问题。

如果有任何帮助，我将非常感激！谢谢 ！

  // ------------------------ ---连接到FTP主机------------------------------------------- -  
 $ conn_id = ftp_connect（$ _ COOKIE [process-1]）或死（无法连接到FTP服务器）; 
 $ login_result = ftp_login（$ conn_id，$ _COOKIE [process-2]，$ _COOKIE [process-3]）; 
 // ---------------------------验证FTP Logiin（用户名，密码）--------- ---------------- 
 if（！$ login_result）die（FTP登录失败，联系支持人@ [e-mail]）; 
 ftp_pasv（$ conn_id，true）; 
 
 $ current_dir = ftp_pwd（$ conn_id）; 
 $ chdir = ftp_chdir（$ conn_id，$ _ COOKIE [process-5]）; 
 if（！$ chdir）echoChange Directory failed。Origin =。$ current_dir。 ;目的地：。$ _ COOKIE [process-5]; 
 
 echo ftp_pwd（$ conn_id）。< br>; 
 
 $ server_file = $ _GET ['file']; 
 
 $ fp = fopen（'php：// stdout'，'w +'）; 
 if（ftp_get（$ conn_id，$ fp，$ server_file，FTP_BINARY））{
 echo已成功写入$ local_file \ n; 
} else {
 echoThere's a problem \\\
; 
} 
 
 ftp_close（$ conn_id）; 
  

解决方案

  //让浏览器下载任何你输出的
头（'Content-type：file / binary'）; 
 
 //设置正确的文件名
 header（'Content-Disposition：attachment; filename =''。$ file。''）; 
  

I am currently implementing a system for users to download files from the ftp without the actual need of a ftp client. I have already developed a login system and have successfully managed to list out the files from the folder. However, I intend to make the download process using ftp_get with a "save as" prompt.

I have referred to http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/PHP_Databases/Q_23210157.html#mainSection but the solution stated wasn't conclusive.

I did use one of the suggestion in the previous forum topic, but I got a msg "There was a problem" after executing ftp_get.

I will really appreciate with any help given ! Thanks !

    //--------------------------- Connects to FTP host ---------------------------------------------
$conn_id = ftp_connect($_COOKIE["process-1"]) or die("Couldn't connect to FTP server");
$login_result = ftp_login($conn_id, $_COOKIE["process-2"], $_COOKIE["process-3"]);
//--------------------------- Validates FTP Logiin (username,password) -------------------------
if(!$login_result) die("FTP Login failed. Contact support @ [e-mail]");
ftp_pasv($conn_id,true);

$current_dir = ftp_pwd($conn_id);
$chdir = ftp_chdir($conn_id,$_COOKIE["process-5"]);
if(!$chdir) echo "Change Directory failed. Origin = " .$current_dir. "; Destination: ".$_COOKIE["process-5"];

echo ftp_pwd($conn_id) ."<br>";

$server_file = $_GET['file'];

$fp = fopen('php://stdout', 'w+');
if (ftp_get($conn_id, $fp, $server_file, FTP_BINARY)) {
        echo "Successfully written to $local_file\n";
} else {
        echo "There was a problem\n";
}

ftp_close($conn_id);

解决方案

// make the browser download anything you output
header('Content-type: file/binary');

// set the correct filename
header('Content-Disposition: attachment; filename="'.$file.'"');
