Upload image retrieving data via $ _REQUEST with JSON

Goodnight everyone, I need to upload an image to a folder named “church” retrieving data via $ _REQUEST, you see, my page sends data to a file named “data.php” this way:

$. ajax ({
url: 'data.php'
date: {
                "name": image_desc,
                "image": image_url,
"url": url_link
}

The page has data.php this code:

<php
$name = $ _REQUEST ['name'];
$image = $ _REQUEST ['image'];
$url = addslashes ($ _REQUEST ['url']);
$uploadd = 'church /';
// till here code works fine
if I use -> echo $ image
//Its prints: C: \\ fakepath \\ frieds.jpg which is not the problem.
The problem is the time to upload the image folder to church:

// Do not know what I use on the lines below to the image is moved to folder
$fileName = $_FILES [$image] ['name'];
$tmpnam = $_FILES [$image] ['tmp_name'];
$fileSize = $_FILES [$image] ['size'];
$fileType = $_FILES [$image] ['type'];
$filePath = $uploadd. $fileName;
$result = move_uploaded_file ($tmpnam, $filePath);

if ($result) {
echo "Error uploading file";
exit;
}

The above code always return me several errors eg:

Notice: Undefined index: C: \\ fakepath \\ frieds.jpg in [My-Local-Folder]\\data.php on line 7

Notice: Undefined index: C: \\ fakepath \\ frieds.jpg in [My-Local-Folder]\\data.php on line 8

Notice: Undefined index: C: \\ fakepath \\ frieds.jpg in [My-Local-Folder]\\data.php on line 9

Notice: Undefined index: C: \\ fakepath \\ frieds.jpg in [My-Local-Folder]\\data.php on line 10
Error uploading file

I appreciate the responses

I dont think you can index the $_FILES super global like that. you should add this code on data.php to see whats in $_FILES

echo '<pre>'; print_r($_FILES); echo '</pre>';
