使用 PHP 将单个图像文件上传到 FTP

问题描述

把我的头发拉出来一点.我想做的只是有一个 HTML 表单，然后 PHP 将所选文件上传到 FTP 服务器上的某个目录，但似乎没有任何工作正常.

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.

这是 html 表单:

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>

这是它下面的 PHP(在同一个文件上):

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);
?>

似乎连接到 FTP 正常，但没有上传 - 失败.我假设这与我处理要上传的文件的方式有关..?

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..?

另外，当我在这里时，如何将已上传文件的名称设置为变量?

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

推荐答案

在这里修改你的代码

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

这里我把 $_POST 改成了 $_FILES....

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