使用PHP将单个图像文件上传到FTP [英] Upload single image file to FTP using PHP

问题描述

在这里拉出我的头发。我想要做的只是使用HTML表单，然后使用PHP将所选文件上传到FTP服务器上的某个目录，但似乎没有任何问题。

这里是html表单：

 < form action =enctype =multipart / form-datamethod =post > 
< input name =filetype =file/> 
< input name =submittype =submitvalue =Upload File/> 
< / form> 
  

以下是它下面的PHP（在同一个文件中）：

 <？php 
 $ ftp_server =myftp.co.uk; 
 $ ftp_user_name =myusername; 
 $ ftp_user_pass =mypass; 
 $ destination_file =/ public_html / my / directory /; 
 $ source_file = $ _POST ['file'] ['tmp_name']; 
 
 //设置基本连接
 $ conn_id = ftp_connect（$ ftp_server）; 
 ftp_pasv（$ conn_id，true）; 
 
 //使用用户名和密码登录
 $ login_result = ftp_login（$ conn_id，$ ftp_user_name，$ ftp_user_pass）; 
 
检查连接
 if（（！！conn_id）||（！$ login_result））{
 echoFTP连接失败！ 
 echo尝试连接到用户$ ftp_user_name的$ ftp_server; 
出口; 
} else {
 echo连接到$ ftp_server，用户$ ftp_user_name; 
} 
 
 //上传文件
 $ upload = ftp_put（$ conn_id，$ destination_file，$ source_file，FTP_BINARY）; 
 
 //检查上传状态
 if（！$ upload）{
 echoFTP upload has failed！; 
} else {
 echo上传$ source_file到$ ftp_server作为$ destination_file; 
} 
 
 //关闭FTP流
 ftp_close（$ conn_id）; 
？> 
  

它似乎连接到FTP正常，但不上载 - 失败。我假设这是与我处理文件上传的方式有关..？

另外，当我在这里时，我该如何设置作为变量上传的文件的名称？

解决方案

在此处更改您的代码

  $ source_file = $ _FILES ['file'] ['tmp_name']; 
  

这里我已将$ _POST更改为$ _FILES ....

Pulling my hair out a bit here. All I want to do is have a HTML form and then PHP to upload the selected file to a certain directory on an FTP server, but nothing seems to be working correctly.

Here's the html form :

<form action="" enctype="multipart/form-data" method="post">
<input name="file" type="file" />
<input name="submit" type="submit" value="Upload File" />
</form>

And here's the PHP below it (on the same file):

<?php
$ftp_server = "myftp.co.uk";
$ftp_user_name = "myusername";
$ftp_user_pass = "mypass";
$destination_file = "/public_html/my/directory/";
$source_file = $_POST['file']['tmp_name'];

// set up basic connection
$conn_id = ftp_connect($ftp_server);
ftp_pasv($conn_id, true); 

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); 

// check connection
if ((!$conn_id) || (!$login_result)) { 
    echo "FTP connection has failed!";
    echo "Attempted to connect to $ftp_server for user $ftp_user_name"; 
    exit; 
} else {
    echo "Connected to $ftp_server, for user $ftp_user_name";
}

// upload the file
$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); 

// check upload status
if (!$upload) { 
echo "FTP upload has failed!";
} else {
echo "Uploaded $source_file to $ftp_server as $destination_file";
}

// close the FTP stream 
ftp_close($conn_id);
?>

It seems to connect to the FTP ok, but doesn't upload - failed. I'm assuming it's something to do with the way I'm handling the file to be uploaded..?

Also, while I'm here, how do I set the name of the file that's been uploaded as a variable?

解决方案

Change your code here

$source_file = $_FILES['file']['tmp_name']; 

Here i have changed $_POST to $_FILES....
