在PHP中，move_uploaded_file将文件上传到一个目录，但是无法上传到另一个目录吗？

Question

I am relatively new to PHP, and am working on a website which should accept functionality for when user's upload pdf, doc, or docx files. 我对PHP相对较新，并且正在一个网站上工作，该网站应该接受用户上载pdf，doc或docx文件时的功能。 I was able to look up code online and see what the html form looks like (not my code, as I am simply trying to see if bare functionality for uploading works right now) and also the code for processing the upload. 我能够在线查找代码，并查看html表单的外观（不是我的代码，因为我只是想立即查看裸露的上传功能是否正常工作）以及处理上载的代码。 I will put the codes below, and I don't think there's anything wrong with the code itself, but maybe something to do with permissions for the directory I'm uploading the files to. 我将代码放在下面，我认为代码本身没有任何问题，但也许与我要将文件上传到的目录的权限有关。 Note : question might be too long, skip to end for clear question and to see what I've tried so far) 注意：问题可能太长，请跳到结尾以解决明确的问题，并查看到目前为止我已尝试过的操作）

Here is the HTML (sample.php) for the form: 这是表单的HTML（sample.php）：

<!DOCTYPE html>
<html>
    <body>

    <form action="docs.php" method="post" enctype="multipart/form-data">
        Select document to upload:
        <input type="file" name="fileToUpload" id="fileToUpload">
        <input type="submit" value="Upload Document" name="submit">
    </form>

    </body>
</html>

Here is the PHP code (docs.php) that is used to upload the file to the specified directory: 这是用于将文件上传到指定目录的PHP代码（docs.php）：

<?php
$target_dir = "../../UPLOADS/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$documentFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = filesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check > 0) {
        echo "File is a document";
        $uploadOk = 1;
    } else {
        echo "File is not a document.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 100000000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($documentFileType != "pdf" && $documentFileType != "doc" && 
$documentFileType != "docx") {
        echo "Sorry, only PDF, DOC, & DOCX files are allowed.";
        $uploadOk = 0;
    }
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) 
{
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has 
been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?>

So, with the code above, I am successfully able to upload a file to the path specified in the PHP code ("../../UPLOADS/"). 因此，使用上面的代码，我可以成功地将文件上传到PHP代码中指定的路径（“ ../../UPLOADS/”）。 However, if I try to change this path, all I get as output on the webpage is "File is a documentSorry, there was an error uploading your file." 但是，如果我尝试更改此路径，则在网页上显示的所有内容是“文件是documentSorry，上传文件时出错。”

Now, the path I am giving instead of "../../UPLOADS/" is just "test/". 现在，我提供的路径不是“ ../../UPLOADS/”，而是“ test /”。 I created another folder in the directory where my webpages are, and named it "test" 我在网页所在的目录中创建了另一个文件夹，并将其命名为“ test”

I am a university student, and so I am using my Linux account under my school's AFS servers. 我是一名大学生，因此我在学校的AFS服务器下使用Linux帐户。 After I ssh into my account, I have to cd into my public_html directory. SSH进入我的帐户后，我必须进入cd到public_html目录。 Once I am there, it contains: 我到那里后，它包含：

UPLOADS/   
resport/
download/

The directory "resport" contains subdirectories for where my webpages are in, so if I cd into resport, I see: 目录“ resport”包含网页所在的子目录，因此，如果我进入resport，则会看到：

login/
student/

The directory "student" contains the subdirectory "UPLOADS" and also other webpages, so if I cd into student, I see: 目录“ student”包含子目录“ UPLOADS”以及其他网页，因此，如果我将CD装入学生，则会看到：

sample.php
docs.php
test/

The problem (clear and simple): I'd like it to be so that I can upload files into test in the "resport" directory and not UPLOADS in the "public_html" directory. 问题（清晰而又简单）：我希望这样做，以便可以将文件上传到“ resport”目录中的测试中，而不是“ public_html”目录中的UPLOADS。 I am able to upload files into "public_html/UPLOADS" (the path relative to where sample.php and docs.php is "../../UPLOADS/") but I need to upload the files into "public_html/resport/student/test" (the path relative to where sample.php and docs.php is "test/") 我可以将文件上传到“ public_html / UPLOADS”（相对于sample.php和docs.php的路径是“ ../../UPLOADS/”），但是我需要将文件上传到“ public_html / resport /学生/测试”（相对于sample.php和docs.php的路径为“ test /”）

What I've tried: I have checked permissions for the UPLOADS directory and it is drwxrwxrwx so I also set the same permissions for the test directory, and gave it a go, but nothing changed. 我尝试过的操作：我已经检查了UPLOADS目录的权限，它是drwxrwxrwx，所以我也为测试目录设置了相同的权限，并给了它一个权限，但是没有任何改变。 I was still seeing "File is a documentSorry, there was an error uploading your file." 我仍然看到“文件是文档抱歉，上传您的文件时出错”。 I have also tried renaming " test " to " UPLOADS " and changing permissions again, but still nothing. 我也尝试过将“ test ”重命名为“ UPLOADS ”，然后再次更改权限，但还是没有。 I'm not sure what the issue could be. 我不确定是什么问题。 I'd greatly appreciate any help, thanks! 非常感谢您的帮助，谢谢！

UPDATE Put a full path to test/ instead of a relative one. 更新放置完整的测试路径，而不是相对路径。 Something like this: 像这样：

/afs/univ/u/c/r/ucid/public_html/resport/student/test/

but still no luck Instead of echoing 但还是没有运气

echo "Sorry, there was an error uploading your file.";

I tried changing it to: 我尝试将其更改为：

echo " Not uploaded because of error #".$_FILES["file"]["error"];

but all I get now is: 但是我现在得到的是：

"File is a document Not uploaded because of error #"

There is no number after 之后没有数字

.$_FILES["file"]["error"]

Change: $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); 更改： $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);

To: $target_file = $target_dir . $_FILES["fileToUpload"]["name"]; 到： $target_file = $target_dir . $_FILES["fileToUpload"]["name"]; $target_file = $target_dir . $_FILES["fileToUpload"]["name"];

The basename() command changes the directory to put the file. basename()命令更改目录以放置文件。

Make sure the / after the directory name is set. 确保设置了目录名称后的/ 。
