I have an app where a user reviews an array of users. Example: ["user1","user2","user3","user4"] When the user reviews the first user the app should present the second user for voting. Unfortunately when a user votes on the user2, user3, user4; the value for user1 is what's put in the database. I tested the PHP via postman and there's no issue there, so it has to be in the swift code. Here is my code:
func loadCards()->[String] {
let username = user!["username"] as! String
let url = URL(string: "http://localhost/shotsCenter.php")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
let body = "username=\(username)"
request.httpBody = body.data(using: .utf8)
// launch session
URLSession.shared.dataTask(with: request) { data, response, error in
// getting main queue of proceeding inf to communicate back, in another way it will do it in background
// and user will no see changes :)
DispatchQueue.main.async(execute: {
if error == nil {
do {
let json = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? [String: AnyObject]
// clean up
self.valueArray.removeAll(keepingCapacity: false)
self.circleArray.removeAll(keepingCapacity: false)
// delcare new secure var to store json
guard let parseJSON = json else {
print("Error while parsing")
return
}
// declare new secure var to store $returnArray["users"]
guard let parseUSERS = parseJSON["users"] else {
print(parseJSON["message"])
return
}
self.valueArray = parseUSERS as! [AnyObject]
if self.valueArray.count > 0 {
let num_currentLoadedCardsArrayCap = (self.valueArray.count > MAX_BUFFER_SIZE) ? MAX_BUFFER_SIZE : self.valueArray.count
for (i, value) in self.valueArray.enumerated() {
let ava = self.valueArray[i]["ava"]
let id = self.valueArray[i]["id"]
let age = (NSString(format: "%@", self.valueArray[i]["age"] as! CVarArg))
let city = self.valueArray[i]["city"]
let state = self.valueArray[i]["state"]
self.age.append(age as AnyObject)
self.city.append(city as AnyObject)
self.state.append(state as AnyObject)
let url = NSURL(string: ava! as! String)!
let imageData = try? Data(contentsOf: url as URL)
let image = UIImage(data: imageData!)!
self.circleArray.append(image)
let reviewed = self.valueArray[i]["username"]
self.reviewed.append((reviewed as AnyObject) as! String)
print("reviewed user", reviewed! as Any)
let newCard = self.createDraggableViewWithData(at: i, value:value as! NSDictionary)
self.allCardsArray.append(newCard)
if i < num_currentLoadedCardsArrayCap {
self.currentLoadedCardsArray.append(newCard)
}
}
for (i,_) in self.currentLoadedCardsArray.enumerated() {
if i > 0 {
self.viewTinderBackGround.insertSubview(self.currentLoadedCardsArray[i], belowSubview: self.currentLoadedCardsArray[i - 1])
}
else {
self.viewTinderBackGround.addSubview(self.currentLoadedCardsArray[i])
}
self.currentIndex += 1
}
self.animateCardAfterSwiping()
self.perform(#selector(self.createDummyCard), with: nil, afterDelay: 1.0)
}
} catch {
// get main queue to communicate back to user
DispatchQueue.main.async(execute: {
let message = "\(error)"
})
return
}
} else {
DispatchQueue.main.async(execute: {
let message = error!.localizedDescription
})
return
}
})
} .resume()
return reviewed
}
func insertShot(_ rating: String, _ reviewed2: NSDictionary) {
let reviewer = user!["username"] as! String
let reviewed2 = reviewed[index]
let url = URL(string: "http://localhost/shotsCenter.php")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
// param to be passed to php file
let param = [
