Says Class 'update_user_info' not found in \android_login_example\login.php Here is Login.php...
IDK whats happening but i also tried removing public in front of functions in update_user_info.php file! It didnt worked! Im creating a login page and registration page for an android app!
Thanks Tracy
<?php
require_once 'update_user_info.php';
$db = new update_user_info();
// json response array
$response = array("error" => FALSE);
if (isset($_POST['email']) && isset($_POST['password'])) {
// receiving the post params
$email = $_POST['email'];
$password = $_POST['password'];
// get the user by email and password
$user = $db->VerifyUserAuthentication($email, $password);
if ($user != false) {
// use is found
$response["error"] = FALSE;
$response["uid"] = $user["unique_id"];
$response["user"]["name"] = $user["name"];
$response["user"]["email"] = $user["email"];
$response["user"]["age"] = $user["age"];
$response["user"]["gender"] = $user["gender"];
echo json_encode($response);
} else {
// user is not found with the credentials
$response["error"] = TRUE;
$response["error_msg"] = "Login credentials are wrong. Please try again!";
echo json_encode($response);
}
} else {
// required post params is missing
$response["error"] = TRUE;
$response["error_msg"] = "Required parameters email or password is missing!";
echo json_encode($response);
}
?>
Now This is update_user_info.php..
<?php
function StoreUserInfo($name, $email, $password, $gender, $age) {
$hash = $this->hashFunction($password);
$encrypted_password = $hash["encrypted"]; // encrypted password
$salt = $hash["salt"]; // salt
$stmt = $this->conn->prepare("INSERT INTO android_php_post(name, email,
encrypted_password, salt, gender, age) VALUES(?, ?, ?, ?, ?, ?)");
$stmt->bind_param("ssssss", $name, $email, $encrypted_password, $salt, $gender, $age);
$result = $stmt->execute();
$stmt->close();
// check for successful store
if ($result) {
$stmt = $this->conn->prepare("SELECT name, email, encrypted_password, salt, gender, age FROM android_php_post WHERE email = ?");
$stmt->bind_param("s", $email);
$stmt->execute();
$stmt-> bind_result($token2,$token3,$token4,$token5,$token6,$token7);
while ( $stmt-> fetch() ) {
$user["name"] = $token2;
$user["email"] = $token3;
$user["gender"] = $token6;
$user["age"] = $token7;
}
$stmt->close();
return $user;
} else {
return false;
}
}
function hashFunction($password) {
$salt = sha1(rand());
$salt = substr($salt, 0, 10);
$encrypted = base64_encode(sha1($password . $salt, true) . $salt);
$hash = array("salt" => $salt, "encrypted" => $encrypted);
return $hash;
}
function VerifyUserAuthentication($email, $password) {
$stmt = $this->conn->prepare("SELECT name, email, encrypted_password, salt, gender, age FROM android_php_post WHERE email = ?");
$stmt->bind_param("s", $email);
if ($stmt->execute()) {
$stmt-> bind_result($token2,$token3,$token4,$token5,$token6,$token7);
while ( $stmt-> fetch() ) {
$user["name"] = $token2;
$user["email"] = $token3;
$user["encrypted_password"] = $token4;
$user["salt"] = $token5;
$user["gender"] = $token6;
$user["age"] = $token7;
}
$stmt->close();
// verifying user password
$salt = $token5;
$encrypted_password = $token4;
$hash = $this->CheckHashFunction($salt, $password);
// check for password equality
if ($encrypted_password == $hash) {
// user authentication details are correct
return $user;
}
} else {
return NULL;
}
}
function checkHashFunction($salt, $password) {
$hash = base64_encode(sha1($password . $salt, true) . $salt);
return $hash;
}
function CheckExistingUser($email) {
$stmt = $this->conn->prepare("SELECT email from android_php_post WHERE email = ?");
$stmt->bind_param("s", $email);
$stmt->execute();
$stmt->store_result();
if ($stmt->num_rows > 0) {
// user existed
$stmt->close();
return true;
} else {
// user not existed
$stmt->close();
return false;
}
}
?>
You need to encapsulate your update_user_info.php in class if you are going to use it as a class
<?php
class update_user_info {
function StoreUserInfo($name, $email, $password, $gender, $age) {
$hash = $this->hashFunction($password);
$encrypted_password = $hash["encrypted"]; // encrypted password
$salt = $hash["salt"]; // salt
$stmt = $this->conn->prepare("INSERT INTO android_php_post(name, email,
encrypted_password, salt, gender, age) VALUES(?, ?, ?, ?, ?, ?)");
$stmt->bind_param("ssssss", $name, $email, $encrypted_password, $salt, $gender, $age);
$result = $stmt->execute();
$stmt->close();
// check for successful store
if ($result) {
$stmt = $this->conn->prepare("SELECT name, email, encrypted_password, salt, gender, age FROM android_php_post WHERE email = ?");
$stmt->bind_param("s", $email);
$stmt->execute();
$stmt-> bind_result($token2,$token3,$token4,$token5,$token6,$token7);
while ( $stmt-> fetch() ) {
$user["name"] = $token2;
$user["email"] = $token3;
$user["gender"] = $token6;
$user["age"] = $token7;
}
$stmt->close();
return $user;
} else {
return false;
}
}
function hashFunction($password) {
$salt = sha1(rand());
$salt = substr($salt, 0, 10);
$encrypted = base64_encode(sha1($password . $salt, true) . $salt);
$hash = array("salt" => $salt, "encrypted" => $encrypted);
return $hash;
}
function VerifyUserAuthentication($email, $password) {
$stmt = $this->conn->prepare("SELECT name, email, encrypted_password, salt, gender, age FROM android_php_post WHERE email = ?");
$stmt->bind_param("s", $email);
if ($stmt->execute()) {
$stmt-> bind_result($token2,$token3,$token4,$token5,$token6,$token7);
while ( $stmt-> fetch() ) {
$user["name"] = $token2;
$user["email"] = $token3;
$user["encrypted_password"] = $token4;
$user["salt"] = $token5;
$user["gender"] = $token6;
$user["age"] = $token7;
}
$stmt->close();
// verifying user password
$salt = $token5;
$encrypted_password = $token4;
$hash = $this->CheckHashFunction($salt, $password);
// check for password equality
if ($encrypted_password == $hash) {
// user authentication details are correct
return $user;
}
} else {
return NULL;
}
}
function checkHashFunction($salt, $password) {
$hash = base64_encode(sha1($password . $salt, true) . $salt);
return $hash;
}
function CheckExistingUser($email) {
$stmt = $this->conn->prepare("SELECT email from android_php_post WHERE email = ?");
$stmt->bind_param("s", $email);
$stmt->execute();
$stmt->store_result();
if ($stmt->num_rows > 0) {
// user existed
$stmt->close();
return true;
} else {
// user not existed
$stmt->close();
return false;
}
}
}
Or convert class method calls to plain functions:
$user = $db->VerifyUserAuthentication($email, $password);
to
$user = VerifyUserAuthentication($email, $password);
