Question

我编码为注册代码，但它不会注册，我正在将Android Studio与phpmysql一起使用。当我单击注册按钮时，它不会注册，也无法保存在本地主机的数据库中。我的代码已经为数据库设置了，但是我不明白注册按钮没有执行任何操作的问题。我目前也正在使用凌空将数据从android studio传递到phpmysql数据库。

地主注册类。

   public class Landlordregistration extends AppCompatActivity {



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_landlordregistration);

        final EditText Name = (EditText)findViewById(R.id.lanname);
        final EditText Username = (EditText)findViewById(R.id.lanusername);
        final EditText Password = (EditText)findViewById(R.id.password);
        final EditText Phone = (EditText)findViewById(R.id.phone);
        final EditText Address = (EditText)findViewById(R.id.lanaddress);

        final Button Landlordregister = (Button)findViewById(R.id.landlordregister);

        Landlordregister.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                final String lanName = Name.getText().toString();
                final String lanUsername = Username.getText().toString();
                final String password = Password.getText().toString();
                final String phone = Phone.getText().toString();
                final String address = Address.getText().toString();

                Response.Listener<String> responseListener = new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        try {
                            JSONObject jsonResponse = new JSONObject(response);
                            boolean success = jsonResponse.getBoolean("success");

                            if (success) {
                                Intent intent = new Intent(Landlordregistration.this, Loginlandlord.class);
                                Toast toast = Toast.makeText(getApplicationContext(), "Successfully Registered", Toast.LENGTH_LONG);
                                toast.show();
                                Landlordregistration.this.startActivity(intent);
                            }else{
                                AlertDialog.Builder builder = new AlertDialog.Builder(Landlordregistration.this);
                                builder.setMessage("Registration failed")
                                        .setNegativeButton("Try Again", null)
                                        .create()
                                        .show();
                            }

                        }
                        catch (JSONException e){
                            e.printStackTrace();
                        }
                    }
                };
                LandlordregistrationRequest landlordregistrationRequest = new LandlordregistrationRequest(lanName, lanUsername, password, phone, address, responseListener);
                RequestQueue queue = Volley.newRequestQueue(Landlordregistration.this);
                queue.add(landlordregistrationRequest);
            }
        });

    }

}

房东注册要求类

public class LandlordregistrationRequest extends StringRequest {


private static String URL_REGIST="http://127.0.0.1/script/registerLandlordtest.php";
private Map<String, String> params;

public LandlordregistrationRequest(String lanName, String lanUsername, String password, String phone, String address, Response.Listener<String> listener ){
    super(Method.POST, URL_REGIST, listener, null);
    params = new HashMap<>();
    params.put("lanName", lanName);
    params.put("lanUsername", lanUsername);
    params.put("password", password);
    params.put("phone", phone);
    params.put("address", address);

}
@Override
public Map<String, String> getParams(){
    return params;
}

}

registerLandlord.php

<?php
require "init.php";
$connect = mysqli_connect("localhost","root","","mytenant");

如果（$ _SERVER ['REQUEST_METHOD'] =='POST'）{

 $name = $_POST["lanName"]; 
 $lanName = $_POST["lanUsername"];
 $password = $_POST["password"];
 $phone = $_POST["phone"];
 $address = $POST["address"];


$statement = mysqli_prepare($connect, "INSERT INTO landlord(lanName, lanUsername, password, phone, address) VALUES(?, ?, ?, ?, ?)");
mysqli_stmt_bind_param($statement, "sssss", "$lanName", "$lanUsername", "$password", "$phone", "$address");
mysqli_stmt_execute($statement);




if ( mysqli_query($con, $sql) ) {
    $result["success"] = "1";
    $result["message"] = "success";

    echo json_encode($result);
    mysqli_close($con);

} else {

    $result["success"] = "0";
    $result["message"] = "error";

    echo json_encode($result);
    mysqli_close($con);
}

}
