Why would the $_FILES['userfile']['name'] be empty/blank?

[dadofgage]

Ok, I have a basic script to upload an image.

<?php

$uploaddir = '/public_html/myfolder/mysubfolder/';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);

echo $_FILES['userfile']['name'].'<br>';
echo $uploaddir.'<br>';
echo $uploadfile.'<br>';

echo '<pre>';
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
   echo "File is valid, and was successfully uploaded.\n";
} else {
   echo "Possible file upload attack!\n\n";
}

echo 'Here is some more debugging info:';
print_r($_FILES);

print "</pre>";

The form has the proper enctype="multipart/form-data" attribute on it.

When this uploads, the first echo $_FILES['userfile']['name'] is blank.

But when the print_r($_FILES) is executed, it shows:

Here is some more debugging info:Array
(
    [filebyuser] => Array
        (
            [name] => kramer.jpg
            [type] => image/jpeg
            [tmp_name] => /tmp/phpplFX2y
            [error] => 0
            [size] => 32910
        )

)

What am I missing here?

The element 'userfile' in the file array is merely an example name used on many tutorial sites. Your form element is called filebyuser so that's what you have to use.

$_FILES['filebyuser']['name'] will not be blank.

Hope this fixes your problem.

Well, now I get a different error:

move_uploaded_file(/home/myname/public_html/folder/uploadedfiles/napoleon.jpg): failed to open stream: Permission denied in ...

[arun_md]

In this error You have to set all access permission to that folder.

By use of chmod(foldername,0777) first you set this permission to your uploading folder , then you won't get that error.

[trhynard]

Make sure that you have write permission to the folder that you are trying to upload the picture to.

Edit:

Just as he ^ said

Yea, I thought the permissions were set correctly, but obviously not.

Thanks for your help.

This is appreciated!
