move_uploaded_file() failed to open stream

问题:

I've done your standard checks (is the directory there, are lax enough permissions set), and I'm pretty sure I've covered your standard stupid human tricks. Here's the code that's failing:

move_uploaded_file($_FILES['image1']['tmp_name'], "/public_html/flashsale/assets/img/products/T".$_FILES['image1']['name']);

The directory is there - I copied the path from FileZilla. I even set the permissions to 777, both in FileZilla and in the file manager on the HostGator control panel. This code generates two warnings:

Message: move_uploaded_file(/public_html/flashsale/assets/img/products/Tsirloin.jpg) [function.move-uploaded-file]: failed to open stream: No such file or directory

Message: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/phpI5GZ3S' to '/public_html/flashsale/assets/img/products/Tsirloin.jpg'

In that order. So, the file is being uploaded, the directory exists and is set to 777, what else could I be missing?

回答1:

you do not need to put the full directory to the file. try to remove /public_html/flashsale/ from your link and see if that will work. In addition, the file does not need to have 777 permission, I myself upload files to folders with 755 permissions.

also, you can use getcwd(); in the directory your aiming to. the function will give you the directory that you need to use for moving your file. source

The Problem

$dirpath = dirname(getcwd())

This is what I used initially to get the directory path to my /public_html/upload folder. $dirpath will contain

/public_html/upload

The Solution(On server)

$dirpath = realpath(dirname(getcwd()))

Since I’m on a shared hosting environment, the right way of getting move_uploaded_file to work is using this as the destination: realpath(dirname(getcwd())) returns something like:

/home/cpanelusername/public_html/upload

Make sure the path you are traversing. public_html is not required

$image=basename($_FILES['file']['name']);
$image=str_replace(' ','|',$image);

$tmppath="images/".$image;

        if(move_uploaded_file($_FILES['file']['tmp_name'],$tmppath))
        {
         echo "success";
        }
        else
        {
         echo "fail";
        }

Hope this helps

For Ubuntu 14.04 with XAMPP, I also have problem with upload but after I have fixed with sudo chmod -R 777 destination, it works well.

Here is what I did:

Temporary folder to upload in my Ubuntu 14.04 XAMPP is /opt/lampp/temp/. If I want my upload files to /opt/lampp/temp/testupload as destination folder, then I need config bellow.

1. Go to temp folder

   cd /opt/lampp/temp/
   

2. Create 'testupload' folder under /opt/lampp/temp/

   sudo mkdir testupload
   

3. Change permission 777

   sudo chmod -R 777 /opt/lampp/temp/testupload/
   

4. PHP code

   move_uploaded_file($_FILES["file"]["tmp_name"], "/opt/lampp/temp/testupload/" . $_FILES["file"]["name"])

Solution for Windows and ISS:

The IUSR account needed permissions in the destination directory. Not the ISS_IUSR account, just the IUSR account.
