How to get data from textFieldDidEndEditing to save to Firebase? - ios

Question

I am trying to get the inputted text from recipeName, servingsNumber, prepTime and cookTime to save to fb.
I know this is close to where I need to be. I am need some help with my save function. I need to assign the textField.text in sendToFirebase() I am able to print out the inputted text into the console and I was able to get it to save a document to FB but the entry was null. What am I missing? I feel like it is here in my code:
import UIKit
import Firebase
class AddRecipeViewController: UIViewController {
#IBOutlet weak var table: UITableView!
#IBOutlet weak var saveButton: UIBarButtonItem!
let db = Firestore.firestore()
var id = UUID().uuidString
var data = [RecipeData]()
let user = Auth.auth().currentUser?.email
var objRecipe = RecipeData.init()
override func viewDidLoad() {
super.viewDidLoad()
table.delegate = self
table.dataSource = self
navigationItem.hidesBackButton = true
let newBackButton = UIBarButtonItem(title: "Cancel", style: .plain, target: self, action: #selector(cancelPressed))
self.navigationItem.leftBarButtonItem = newBackButton
table.register(UINib(nibName: "RecipeNameCell", bundle: nil), forCellReuseIdentifier: "recipeName")
table.register(UINib(nibName: "ServingSizeTableViewCell", bundle: nil), forCellReuseIdentifier: "servings")
table.register(UINib(nibName: "PrepTimeTableViewCell", bundle: nil), forCellReuseIdentifier: "prep")
table.register(UINib(nibName: "CookTimeTableViewCell", bundle: nil), forCellReuseIdentifier: "cook")
}
func sendToFirebase() {
do {
let recipeName = objRecipe.recipeName
let servings = objRecipe.servingsNumber
let prep = objRecipe.prepTime
let cook = objRecipe.cookTime
let user = Auth.auth().currentUser?.email
let id = objRecipe.id
let data = try JSONEncoder().encode(objRecipe)
let dictionary = (try? JSONSerialization.jsonObject(with: data)) as? [String: Any] ?? [:]
db.collection("Recipe").document(objRecipe.id).setData(dictionary)
}
catch {
print(error)
}

You need to fire the sendToFirebase() function:
extension AddRecipeViewController: UITextFieldDelegate {
func textFieldDidEndEditing(_ textField: UITextField) {
switch textField.tag {
case 0:
let recipeName = textField.text!
print(recipeName)
objRecipe.recipeName = textField.text!
sendToFirebase() // Send to firebase
case 1:
let servingSize = textField.text!
print(servingSize)
objRecipe.servingsNumber = textField.text!
sendToFirebase()
case 2:
let prepTime = textField.text!
print(prepTime)
objRecipe.prepTime = textField.text!
sendToFirebase()
case 3:
let cookTime = textField.text!
print(cookTime)
objRecipe.cookTime = textField.text!
sendToFirebase()
default: break
}
}
}
sendToFirebase() function:
func sendToFirebase() {
let recipeName = objRecipe.recipeName
let servings = objRecipe.servingsNumber
let prep = objRecipe.prepTime
let cook = objRecipe.cookTime
let user = Auth.auth().currentUser?.email
let newRecipeRef = db.collection("Recipe").document(objRecipe.id)
newRecipeRef.setData([
"Recipe Name" : recipeName ?? "Empty",
"Serving #" : servings ?? "Empty",
"Prep Time" : prep ?? "Empty",
"Cook Time" : cook ?? "Empty",
"User" : user ?? "No email provided",
])
{ err in
if let err = err {
print("Error adding document: \(err)")
} else {
print("Document added with ID:\(newRecipeRef)")
}
}
}
