Question

我想问一下如何将数据从Xcode 8发布到PHP MySQL数据库中。现在我有 textField用户名和注册按钮来触发功能发布。

到目前为止，这是我的代码。

registerVC.swift

import UIKit
class RegisterVC: UIViewController {
    @IBOutlet var usernametxt: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

    @IBAction func register_click(_ sender: Any) {

        if usernametxt.text!.isEmpty{
            usernametxt.attributedPlaceholder = NSAttributedString(string: "username", attributes: [NSForegroundColorAttributeName: UIColor.red])
        }

        else{
            // Insert data into database  
        }
    }
}

Register.php

<?php
    $connect      = mysqli_connect("", "", "", "");
    global $connect;  
    if(isset($_POST['username']))
    {
        $username       = $_POST['username'];
        $insert         = "INSERT INTO table (username)
                                     VALUES  ('$username')";
        $run            = mysqli_query($connect,$insert);

        $response = array();
        $response["success"] = true; 
        echo json_encode($response);
    }
?>

在else添加sendData(usernametxt.text) 并在VC文件中添加以下功能

func sendData(username : String) {
    var request = URLRequest(url: URL(string:"http://YOUR_WEBPAGE_ADDRESS")!)
    request.httpMethod = "POST"
    let postString = "name="+username
    request.httpBody = postString.data(using: .utf8)
    let task = URLSession.shared.dataTask(with: request) { data, response, error in
    guard let data = data, error == nil else {                                               
        print("error=\(error)")
        return
    }  
    if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {           // check for http errors
        print("statusCode should be 200, but is \(httpStatus.statusCode)")
        print("response = \(response)")
    }

    let responseString = String(data: data, encoding: .utf8)
    print("responseString = \(responseString)")
   }
}
task.resume()
