PHP上传文件问题

Question

Updated!

I have never had a problem with this before, i'm on a local server and UAC is turned off as well.

Here is my form, well, a dumbed down version of the form as there is a lot of text in there:

<form id="setup" name="setup" action="php/process_setup.php" method="post" enctype="multipart/form-data">
   <input type="text" name="cname" id="cname" value="" />
   <input type="text" name="splash" id="splash" />
   <input type="file" name="file"/>
   <input type="text" name="email" id="email" />
   <input type="password" name="password" id="password" />
   <input type="password" name="cpassword" id="cpassword" />
   <input type="submit" value="Submit" name="submit_setup" />
</form>

Here is the PHP im trying:

if ($_FILES["file"]["error"] > 0)
  {
  echo "Error: " . $_FILES["file"]["error"] . "<br>";
  }
else
  {
  echo "Upload: " . $_FILES["file"]["name"] . "<br>";
  echo "Type: " . $_FILES["file"]["type"] . "<br>";
  echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
  echo "Stored in: " . $_FILES["file"]["tmp_name"];
  }

And here is the result:

Notice: Undefined index: file in C:\\xampp\\htdocs\\ppa\\php\\process_setup.php on line 10

Notice: Undefined index: file in C:\\xampp\\htdocs\\ppa\\php\\process_setup.php on line 16 Upload:

Notice: Undefined index: file in C:\\xampp\\htdocs\\ppa\\php\\process_setup.php on line 17 Type:

Notice: Undefined index: file in C:\\xampp\\htdocs\\ppa\\php\\process_setup.php on line 18 Size: 0 kB

Notice: Undefined index: file in C:\\xampp\\htdocs\\ppa\\php\\process_setup.php on line 19 Stored in:

Edit 2

Just did a test to see if PHP has write permission, here is the code:

echo copy("1383778885275.jpg", "C:/xampp/tmp/1383778885275.jpg");

And the result was:

1

And the image IS in the tmp directory..

Answer 1

I am doing it in on a simple way , try having this:

if(!empty($_POST) && !empty($_FILES["file"]["name"]) ){ //check the following post values if not empty
    $name = $_FILES["file"]["name"];
    $temp = $_FILES["file"]["tmp_name"];
    $location= "../images/";
    if(move_uploaded_file($temp, $location.$name)) {
        echo "Uploaded!!!";
    } else {
        echo "Error:";
    }
} else {
    echo "Please choose a file to upload";
}

Answer 2

You probably need to change !empty($_FILES["file"]["tmp_name"] to:

isset($_FILES["file"]["tmp_name"]

and if(move_uploaded_file($temp, $location.$name)) { to:

if(move_uploaded_file($temp, $location.basename($name))) {

Emphasis on basename() .

Answer 3

According to your notice information ,the $_FILES is probably empty.You can check the following issues:

1.Make sure your directory has permissions for the tmp and upload directories.
2.Make sure the value of `file_uploads` option in `php.ini` is `On`

Thanks for all the help guys. It seems that there was an issue in some of the code I didn't include.. :/

Basically:

<form id="setup" name="setup" action="php/process_setup.php" method="post" enctype="multipart/form-data">

.....

....

<input type="file" name="logo"/>

...


.....

somewhere had some dodgy code I deleted

....

</form>

Thanks for the help.
