Search bar in Swift not searching with a PHP file - ios

Question

I have no errors in my code but there's definitely something missing. Also there when I press done in the keyboard nothing happens. It might have to do with the search bar function or the table view function. I also have a Search.swift file and I will add it. Any suggestions would be very helpful, I feel really stuck.
SearchBarViewController:
let url = URL(string: "http://127.0.0.1/musicfiles/search.php")
var filteredData = [String]()
var shouldShowSearchResults = false
var search: [Search] = []
var filePath = "http://127.0.0.1/musicfiles/search.php"
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
searchBar.delegate = self
searchBar.returnKeyType = UIReturnKeyType.done
let task = URLSession.shared.dataTask(with: url!) { (data, snapshot, error) in
let retrievedList = String(data: data!, encoding: String.Encoding.utf8)
print(retrievedList!)
self.parseSongs(data: retrievedList!)
}
task.resume()
}
func parseSongs (data: String) {
if (data.contains("*")) {
let dataArray = (data as String).split(separator: "*").map(String.init)
for item in dataArray {
let itemData = item.split(separator: ",").map(String.init)
let searchSong = Search(songname: itemData[0])
search.append(searchSong!)
for s in search {
print(s.searchSongName())
}
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
}
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return search.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! DataCell
let song = search[indexPath.row].searchSongName()
cell.congigureCell(text: song)
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let searchSong = search[indexPath.row].searchSongName()
let fileURLString = "\(filePath)\(searchSong)"
print(fileURLString)
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
if searchBar.text == nil || searchBar.text == "" {
shouldShowSearchResults = false
view.endEditing(true)
filteredData.removeAll()
} else {
shouldShowSearchResults = true
filteredData = search.filter({ (songName) -> Bool in
songName.searchSongName().range(of: searchText) != nil
})
.map { $0.songname }
}
tableView.reloadData()
}

You are loading your data into an array called search.
When you filter your data, you are placing the filtered data into an array called filteredData.
Your tableview always shows the contents of search, so you never see the results of your filtering.
You could check whether filteredData is empty and then return data from that array or search in numberOfRows and cellForRow. Personally I would always use filteredData and make sure that it holds the contents of search when the filter string is empty.
var filteredData = [Search]()
func parseSongs (data: String) {
if (data.contains("*")) {
let dataArray = (data as String).split(separator: "*").map(String.init)
for item in dataArray {
let itemData = item.split(separator: ",").map(String.init)
let searchSong = Search(songname: itemData[0])
search.append(searchSong!)
for s in search {
print(s.searchSongName())
}
self.filterData = self.search
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
}
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return filteredData.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! DataCell
let song = filteredData[indexPath.row].searchSongName()
cell.congigureCell(text: song)
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let searchSong = filteredData[indexPath.row].searchSongName()
let fileURLString = "\(filePath)\(searchSong)"
print(fileURLString)
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
if (searchBar.text ?? "").isEmpty {
view.endEditing(true)
filteredData = search
} else {
filteredData = search.filter({ (songName) -> Bool in
songName.searchSongName().range(of: searchText) != nil
})
}
tableView.reloadData()
}
