I am new in Swift. I have small application which checks if phone number appears more than 1 in the same day, then my application should stop and error out
I tried few ways but it looks to me that the code skips the part which checks phone number in the same day and moves to next step.
import UIKit
import Firebase
//import FirebaseAuth
//import FirebaseDatabase
var ref_login: DatabaseReference!
var refTransaction: DatabaseReference!
var refcustomerdetails: DatabaseReference!
var refcountcheckin: DatabaseReference!
var CustomerName = String()
class ViewController: UIViewController {
@IBOutlet weak var nameText: UITextField!
@IBOutlet weak var nameLabel: UILabel!
@IBOutlet weak var phoneText: UITextField!
@IBOutlet weak var errorText: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
ref_login = Database.database().reference()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func loginPressed(_ sender: Any) {
if self.phoneText.text == "" {
print("Phone is empty")
self.errorText.text = "Phone is empty."
return
}
if self.phoneText.text == "000000000" {
switchownerScreen()
}
else {
Auth.auth().signIn(withEmail: phoneText.text! + "@gmail.com", password: "fingerjoynails", completion: {(user, error) in
if error != nil {
print(error)
self.errorText.text = "Phone does not exist in system."
return
}
if error == nil {
print("self.phoneText.text!",self.phoneText.text!)
//Start checking duplicate checking in the same day
//Start Date to query
let dformatter = DateFormatter()
dformatter.dateFormat = "yyyy-MM-dd"
let dmyString = dformatter.string(from: Date())
let dyourDate = dformatter.date(from: dmyString)
dformatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let dmyStringafd = dformatter.string(from: dyourDate!)
print("dmyStringafd:------",dmyStringafd)
refcountcheckin = Database.database().reference().child("Transactions")
let query = refcountcheckin.queryOrdered(byChild: "CHECK_IN_DATE").queryStarting(atValue: dmyStringafd)
query.observe(.value, with: { (snapshot) in
print("snapshot.childrenCount:----",snapshot.childrenCount)
if snapshot.childrenCount>0{
for transactions in snapshot.children.allObjects as![DataSnapshot]{
let transactionObject = transactions.value as? [String: AnyObject]
let transactionPhone = transactionObject?["PHONE"]
let checkPhone = transactionPhone as! String?
print("self.phoneText.text!",self.phoneText.text!)
if checkPhone == self.phoneText.text! {
self.errorText.text = "You already checked in on today."
print("You already checked in on today.")
return
}
}
}
})
//End checking duplicate checking in the same day
let phone = self.phoneText.text!
//let name = self.nameText.text!
let formatter = DateFormatter()
// initially set the format based on your datepicker date / server String
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let myString = formatter.string(from: Date()) // string purpose I add here
// convert your string to date
let yourDate = formatter.date(from: myString)
//then again set the date format whhich type of output you need
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
// again convert your date to string
let myStringafd = formatter.string(from: yourDate!)
refcustomerdetails = Database.database().reference().child("Users")
let customerdetailsquery = refcustomerdetails.queryOrdered(byChild: "PHONE").queryEqual(toValue: self.phoneText.text!)
customerdetailsquery.observe(.value, with: { (snapshot) in
if snapshot.childrenCount>0{
for transactions in snapshot.children.allObjects as![DataSnapshot]{
let customerdetailsObject = transactions.value as? [String: AnyObject]
let customerFirstName = customerdetailsObject?["FIRST_NAME"]
let customerLastName = customerdetailsObject?["LAST_NAME"]
let firstname = customerFirstName as! String?
let lastname = customerLastName as! String?
CustomerName = firstname! + " " + lastname!
}
}
})
ref_login?.child("Transactions").childByAutoId().setValue(["PHONE": phone, "NAME": CustomerName,"CHECK_IN_DATE": myStringafd, "GIFT_CARD_NUMBER": "N"])
print("Insert into transaction complete.")
self.switchScreen()
}
})
}
}
func switchScreen() {
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let controller = storyboard.instantiateViewController(withIdentifier: "usersVC")
self.present(controller, animated: true, completion: nil)
}
func switchownerScreen() {
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let controller = storyboard.instantiateViewController(withIdentifier: "ownerVC")
self.present(controller, animated: true, completion: nil)
}
func assignbackground(){
let background = UIImage(named: "login.jpg")
var imageView : UIImageView!
imageView = UIImageView(frame: view.bounds)
imageView.contentMode = UIViewContentMode.scaleAspectFill
imageView.clipsToBounds = true
imageView.image = background
imageView.center = view.center
view.addSubview(imageView)
self.view.sendSubview(toBack: imageView)
}
}
On the log I can see application inserts record before checking existing condition. My goal is if the phone number is already inserted in transaction table on today, we should NOT allow end user to insert it again.
