File uploading but name is empty - php

Question

I have an IOS app that uses PHP for my API. My file upload is working fine but the name of the file is not appending to the file. I've mirrored other pages in my app but it's still not working although others are working fine. I’m able to see the file on the server, but the name is notes-.jpg. It’s not appending the puuid to the name per the code. I've implemented MessageKit on the ViewController that isn't working (just in case it makes a difference). Here is my code below, I feel like I'm looking for a needle in a haystack. The code is a little sloppy (please don't judge).
func createBodyWithParams(_ parameters: [String: String]?, filePathKey: String?, imageDataKey: Data, boundary: String) -> Data {
let body = NSMutableData();
if parameters != nil {
for (key, value) in parameters! {
body.appendString("--\(boundary)\r\n")
body.appendString("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n")
body.appendString("\(value)\r\n")
}
}
// if file is not selected, it will not upload a file to server, because we did not declare a name file
var filename = ""
if imageSelected == true {
filename = "notes-\(puuid).jpg"
print("name of file", filename)
}
let mimetype = "image/jpg"
body.appendString("--\(boundary)\r\n")
body.appendString("Content-Disposition: form-data; name=\"\(filePathKey!)\"; filename=\"\(filename)\"\r\n")
body.appendString("Content-Type: \(mimetype)\r\n\r\n")
body.append(imageDataKey)
body.appendString("\r\n")
body.appendString("--\(boundary)--\r\n")
return body as Data
}
func uploadImage(_ image: UIImage, completion: #escaping (URL?) -> Void) {
print("im in upload")
let avame = user!["ava"]
let user_id = user!["id"] as! String
let me = user!["username"] as! String
let recipientfe = getmessages["recipient"]
let uuidfe = getmessages["uuid"] as! String
let recipient = getmessages["username"] as! String
let rid = String(describing: getmessages["sender_id"]!)
let puuid = UUID().uuidString

}
request.httpBody = createBodyWithParams(parameters, filePathKey: "file", imageDataKey: data, boundary: boundary)

}
var message = Message(messageuser: self.sender, image: image)

self.messagesCollectionView.scrollToBottom()
} else {

Helper().showAlert(title: "Error", message: message, in: self)
print("where am i", parsedJSON["message"] as Any)

Answer 1

I figured it out. The body and headers in Swift were incorrect and weren't sending the correct file name.
I changed the body to:
// web development and MIME Type of passing information to the web server
let boundary = "Boundary-\(NSUUID().uuidString)"
request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
// access / convert image to Data for sending to the server
var data = Data()
// if picture has been selected, compress the picture before sending to the server
if image != nil {
data = image.jpegData(compressionQuality: 0.5)!
}
// building the full body along with the string, text, file parameters
request.httpBody = Helper().body(with: parameters, filename: "notes-\(puuid).jpg", filePathKey: "file", imageDataKey: data, boundary: boundary) as Data
