PHP：无法上传文件

Question

I'm having trouble making file uploads with my PHP code. I've checked out a few tutorials and some debug tips and advice (on here and off here), but nothing is working. print_r($_FILES) yields no results. Here's my HTML code:

<form action="admin_avatars.php" method="post" enctype="multipart/form-data">
    <p>Image: <input type="file" name="avatar" id="avatar" /></p>
    <p class="buttonset"><input type="submit" value="Upload" /></p>
</form>

And here's my PHP code (with an ini_get just to make sure my file_uploads is set to "on"):

print("[ini get: ".ini_get("file_uploads")."]<br />");
print("[".$_FILES["avatar"]["name"]. "==".$_FILES["avatar"]["tmp_name"]."]<br />");

And, for this, I get the output:

[ini get: 1]
[==]

Kinda stumped at this point why nothing is uploading or why $_FILES isn't being filled with anything. What small detail am I missing?

Thanks!

Ok, for some reason it suddenly works. And I'm not sure why. All the elements that I can see remain the same, but here's my PHP code (PHP is the only thing I changed):

if($_FILES["character_image"]["name"] <> "") {
    $newfilename = $directory_characters . "/" . createfilename($_REQUEST["character_name"]) . "." . pathinfo($_FILES["character_image"]["name"], PATHINFO_EXTENSION);
    $imagesizeinformation = getimagesize($_FILES["character_image"]["tmp_name"]);
    copy($_FILES["character_image"]["tmp_name"], $newfilename);
}

Just in case, here's my HTML code at its barest:

<form action="admin_characters.php" method="post" enctype="multipart/form-data">
    Image: <input type="file" name="character_image" id="character_image" />
    <p class="buttonset"><input type="submit" value="Add" /></p>
</form>

If anybody knows what fixed my problem, please let everyone know. I'm stumped what happened here that suddenly allowed the images to come through.
