上传图片时出错无此路径或目录

问题描述

美好的一天，我一直在关注教程，并且非常努力地使这个脚本能够工作，我设法解决了很多问题，但是我得到的一个常量问题是：

第93行的/home/xxxxxxx/public_html/regForm.php中没有这样的文件或目录

我想要实现的是让用户在注册时将我的实时服务器/网站上传个人资料图片，这里是我的表格和下面的代码的一部分：

如果一位更有经验的用户可以给它一个扫描并告知我错误的地方，我会非常感激，thanx提前

HTML FORM

 < form ENCTYPE =multipart / form-dataname =registration -formid =regFormmethod =postaction =regForm.php> 
：
：
上传图片：< INPUT NAME =file_upTYPE =file> 
< input type =submitvalue =Registername =registerclass =buttono/> 
< / form> 
  

UPLOAD SCRIPT

  $ file_upload = 真; 
 $ file_up_size = $ _ FILES ['file_up'] ['size']; 
 echo $ _FILES ['file_up'] ['name']; 
 
 if（$ _FILES ['file_up'] ['size']> 250000）{
 $ msg = $ msg。您上传的文件大小超过250KB 
所以请减小文件大小然后上传。< BR>; 
 $ file_upload =false; $！
 
 $ b if（！（$ _ FILES ['file_up'] ['type'] ==image / jpeg或$ _FILES ['file_up'] ['type'] = =image / gif））
 {
 $ msg = $ msg。您上传的文件必须是JPG或GIF，其他文件类型不允许使用< BR>; 
 $ file_upload =false; 
} 
 
 $ file_name = $ _ FILES ['file_up'] ['name']; 
 
 if（$ file_upload ==true）{
 
 $ ftp_server =xxxxxx; 
 $ ftp_conn = ftp_connect（$ ftp_server）或死（无法连接到$ ftp_server）; 
 $ ftp_username ='xxxxxx'; 
 $ ftp_userpass ='xxxxxx'; 
 $ login = ftp_login（$ ftp_conn，$ ftp_username，$ ftp_userpass）; 
 
 $ file = $ file_name; 
 
 //上传文件
 if（ftp_put（$ ftp_conn，public_html / img / userPics，$ file，FTP_ASCII））//这是我怀疑$ b的路径问题$ b {
 echo成功上传$文件。; 
} 
 else 
 {
 echo上传$ file时出错。 
} 
 
 //关闭连接
 ftp_close（$ ftp_conn）; 
} 
  

解决方案

需要使用二进制格式。

FTP_BINARY，而不是FTP_ASCII。

根据手册：

>

• 
  

确保路径是正确的。这可能会有所不同，从不同的服务器。

您还需要在这里一个尾部的斜线：

  public_html / img / userPics / 
 ^ 
  

否则，系统会解释即：

userPicsIMAGE.JPG 而非预期的 userPics / IMAGE.JPG

然而，您可能需要玩弄路径本身。 FTP有点棘手。

即：

• / home / xxxxxxx / public_html / userPics /


• img / userPics /


• ../ img / userPics /

 
 Root> ftp_file.php 
 -img 
 -userPics $ b取决于文件的执行区域。
 $ b 

该文件夹还需要有适当的权限才能写入。

• 通常755。

  
  
  

  't已经设置，以捕获并显示错误/通知：

一个来自FTP手册的例子：

 <？php 
 ftp_chdir（$ conn，'/ www / site /'）; 
 ftp_put（$ conn，'file.html'，'c：/wamp/www/site/file.html'，FTP_BINARY）; 
？> 
  

另一件事是使用true和false。你很可能想要检查真实性/ b

  $ file_upload = true; 
  

而不是字符串文字 $ file_upload =true; $ b pre
$ b pre $ if $（$ file_upload ==true）

到

<$如果（$ file_upload == true）

并且对于

code $ file_upload =false; 检查是否存在错误

至 $ file_upload = false;

测试你的FTP连接， a href =https://stackoverflow.com/a/372​​9769/> https://stackoverflow.com/a/372​​9769/

  try {
 $ con = ftp_connect（$ server）; 
 if（false === $ con）{
抛出新的异常（'Unable to connect'）; 
} 
 
 $ loggedIn = ftp_login（$ con，$ username，$ password）; 
 if（true === $ loggedIn）{
 echo'Success！'; 
} else {
抛出新的异常（'无法登录'）; 
} 
 
 print_r（ftp_nlist（$ con，。））; 
 ftp_close（$ con）; 
} catch（Exception $ e）{
 echoFailure：。 $ E->的getMessage（）; 
 
 $ / code>

命名惯例： p>

我还需要注意的是，在LINUX上， userPics 不同于 userpics ，您的文件夹名称应该是小写字母。

与Windows不区分大小写。

Good day, I have been following a tutorial and have worked really hard to make this script work, I have managed to fix many things however the one constant problem I'm getting is:

No such file or directory in /home/xxxxxxx/public_html/regForm.php on line 93

What I am trying to acomplish is get user to upload a profile pic to my live server / website upon registration, here is part of my form and the code below:

I would greatly appreciate it if a more experienced user can give it a scan and advise to where I am going wrong, thanx in advance

HTML FORM

 <form ENCTYPE="multipart/form-data" name="registration-form" id="regForm" method="post" action="regForm.php">
 :
 :
Upload Picture: <INPUT NAME="file_up" TYPE="file">
<input type="submit"  value="Register" name="register" class="buttono" />
</form>

UPLOAD SCRIPT

$file_upload="true";
$file_up_size=$_FILES['file_up']['size'];
echo $_FILES['file_up']['name'];

if ($_FILES['file_up']['size']>250000){
    $msg=$msg."Your uploaded file size is more than 250KB
 so please reduce the file size and then upload.<BR>";
$file_upload="false";
}

if (!($_FILES['file_up']['type'] =="image/jpeg" OR $_FILES['file_up']['type'] =="image/gif"))
{
    $msg=$msg."Your uploaded file must be of JPG or GIF. Other file types are not allowed<BR>";
$file_upload="false";
}

$file_name=$_FILES['file_up']['name'];

if($file_upload=="true"){

$ftp_server = "xxxxxx";
$ftp_conn = ftp_connect($ftp_server) or die("Could not connect to $ftp_server");
$ftp_username='xxxxxx';
$ftp_userpass='xxxxxx';
$login = ftp_login($ftp_conn, $ftp_username, $ftp_userpass);

$file = $file_name;

// upload file
if (ftp_put($ftp_conn, "public_html/img/userPics", $file, FTP_ASCII)) //here is the problem with the path I suspect
  {
  echo "Successfully uploaded $file.";
  }
else
  {
  echo "Error uploading $file.";
  }

// close connection
ftp_close($ftp_conn);   
}

解决方案

When dealing with images, you need to use a binary format.

FTP_BINARY instead of FTP_ASCII.

As per the manual:

• http://php.net/manual/en/function.ftp-put.php

Make sure the path is correct. This can differ from different servers.

You also need a trailing slash here:

public_html/img/userPics/
                        ^

Otherwise, your system will interpret that as:

userPicsIMAGE.JPG rather than the intended userPics/IMAGE.JPG

Yet, you may need to play around with the path itself. FTP is a bit tricky that way.

I.e.:

• /home/xxxxxxx/public_html/userPics/
• img/userPics/
• ../img/userPics/

Depending on the file's area of execution.

Root > ftp_file.php  
-img  
   -userPics

The folder also needs to have proper permissions to be written to.

• Usually 755.

  Use error reporting if your system isn't already setup to catch and display error/notices:

  • http://php.net/manual/en/function.error-reporting.php

An example from the FTP manual:

<?php 
ftp_chdir($conn, '/www/site/'); 
ftp_put($conn,'file.html', 'c:/wamp/www/site/file.html', FTP_BINARY ); 
?>

Another thing though, the use of of "true" and "false". You're most likely wanting to check for truthness

$file_upload=true;

rather than a string literal $file_upload="true";

same thing for

if($file_upload=="true")

to

if($file_upload==true)

and for $file_upload="false"; to check for falseness

to $file_upload=false;

Read the manual on this:

• http://php.net/manual/en/language.types.boolean.php

Test your FTP connection, pulled from https://stackoverflow.com/a/3729769/

try {
    $con = ftp_connect($server);
    if (false === $con) {
        throw new Exception('Unable to connect');
    }

    $loggedIn = ftp_login($con,  $username,  $password);
    if (true === $loggedIn) {
        echo 'Success!';
    } else {
        throw new Exception('Unable to log in');
    }

    print_r(ftp_nlist($con, "."));
    ftp_close($con);
} catch (Exception $e) {
    echo "Failure: " . $e->getMessage();
}

Naming conventions:

I also need to note that on LINUX, userPics is not the same as userpics, should your folder name be in lowercase letters.

Unlike Windows, which is case-insensitive.
