I need to send 5 strings and 3 integers as parameters to my server. I keep receiving this error back: "Required parameters (name, email, password, gender or dob) is missing!" [found at the end of my php code]. How do I send multiple primitive types as parameters to my server? Prior to messing around with this code, I was using a StringRequest and a HashMap as a return type for the overridden method: getParams(). I have now added the integers...dob_day, dob_month, and dob_year and have run into trouble. Here is some code...
private void registerUser(final String first_name, final String last_name, final String email, final String password, final String gender, final int dob_day, final int dob_month, final int dob_year) {
// Tag used to cancel the request
String cancel_req_tag = "register";
progressDialog.setMessage("Verifying Registration...");
showDialog();
JSONObject jObj = new JSONObject();
try {
jObj.put("first_name", first_name);
jObj.put("last_name", last_name);
jObj.put("email", email);
jObj.put("password", password);
jObj.put("gender", gender);
jObj.put("dob_day", dob_day);
jObj.put("dob_month", dob_month);
jObj.put("dob_year", dob_year);
Log.i("jsonString", jObj.toString());
} catch(Exception e) {
e.printStackTrace();
}
JsonObjectRequest jsonReq = new JsonObjectRequest(Request.Method.POST,
URL_FOR_REGISTRATION, jObj, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.d(TAG, "Register Response: " + response.toString());
hideDialog();
try {
boolean error = response.getBoolean("error");
if (!error) {
String user = response.getJSONObject("user").getString("first_name");
Toast.makeText(getApplicationContext(), "Registration Successful! \nWelcome, " + user +"!", Toast.LENGTH_LONG).show();
SharedPreferences preferences = getSharedPreferences(PREFS_NAME,MODE_PRIVATE);
SharedPreferences.Editor editor = preferences.edit();
editor.putString(PREF_USERNAME, signupInputEmail.getText().toString());
editor.apply();
// Launch login activity
Intent intent = new Intent(
RegisterActivity.this,
LoginActivity.class);
startActivity(intent);
finish();
} else {
String errorMsg = response.getString("error_msg");
Toast.makeText(getApplicationContext(),
errorMsg, Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "Registration Error: " + error.getMessage());
Toast.makeText(getApplicationContext(),
error.getMessage(), Toast.LENGTH_LONG).show();
hideDialog();
}
}) {
/**
* Passing some request headers
*/
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
};
// Adding request to request queue
AppSingleton.getInstance(getApplicationContext()).addToRequestQueue(jsonReq, cancel_req_tag);
}
}
