I'm a newbie with PHP. I am trying to create a log in /register system for a project, so I am using a login system source code I found which has many functions and features like salted passwords. The system itself works fine, but I am trying to add more fields to my MySQL Table. The system had an array for extra columns, but I think it was resulting in bad mysql syntax so I decided to write out the query myself using the variables, but I am not sure how I can give access to the variables to the function. The variables are in the register.php document, here is the code (all of register.php):
if( isset($_POST['submit']) ){
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$user = $_POST['username'];
$sex = $_POST['sex'];
$country = $_POST['strCountryChoice'];
$email = $_POST['email'];
$pass = $_POST['pass'];
$pass2 = $_POST['pass2'];
$birthdate = $_POST['birthdate'];
$created = date("Y-m-d H:i:s");
//need to add a lot more validation functions.. AKA Check if email exists and username. Password > 5 chars
if( $user=="" || $email=="" || $pass=='' || $pass2=='' || $firstname=='' || $lastname='' || $sex='' || $country='' || $birthdate='' ){
echo "Fields Left Blank","Some Fields were left blank. Please fill up all fields.";
exit;
}
if( !$LS->validEmail($email) ){
echo "E-Mail Is Not Valid", "The E-Mail you gave is not valid";
exit;
}
if( !ctype_alnum($user) ){
echo "Invalid Username", "The Username is not valid. Only ALPHANUMERIC characters are allowed and shouldn't exceed 10 characters.";
exit;
}
if($pass != $pass2){
echo "Passwords Don't Match","The Passwords you entered didn't match";
exit;
}
$createAccount = $LS->register($user, $pass,
array(
"email" => $email,
"name" => $firstname,
"lastname" => $lastname,
"gender" => $sex,
"country" => $country,
"DOB" => $birthdate,
"created" => date("Y-m-d H:i:s") // Just for testing
)
);
if($createAccount === "exists"){
echo "User Exists.";
}elseif($createAccount === true){
echo "Success. Created account.";
}
}
The whole system takes place in another file which has the class. Here is the register function:
public function register( $id, $password, $other = array() ){
if( $this->userExists($id) && (isset($other['email']) && $this->userExists($other['email'])) ){
return "exists";
}else{
$randomSalt = $this->rand_string(20);
$saltedPass = hash('sha256', "{$password}{$this->passwordSalt}{$randomSalt}");
if( count($other) == 0 ){
/* If there is no other fields mentioned, make the default query */
//old query: ("INSERT INTO `{$this->dbtable}` (`username`, `password`, `password_salt`) VALUES(:username, :password, :passwordSalt)");
//new query: ("INSERT INTO `{$this->dbtable}` (`username`, 'email' , `password`, `password_salt` , 'name' , 'lastname' , 'gender' , 'country' , 'DOB') VALUES(:username, :email, :pass, :passwordSalt, :firstname, :lastname, :gender, :country, :DOB)");
$sql = $this->dbh->prepare("INSERT INTO `{$this->dbtable}` (`username`, `password`, `password_salt`) VALUES(:username, :password, :passwordSalt)");
}else{
/* if there are other fields to add value to, make the query and bind values according to it */
//old query: ("INSERT INTO `{$this->dbtable}` (`username`, `password`, `password_salt`, $columns) VALUES(:username, :password, :passwordSalt, :$colVals)");
//new query: ("INSERT INTO `{$this->dbtable}` (`username`, 'email' , `password`, `password_salt` , 'name' , 'lastname' , 'gender' , 'country' , 'DOB') VALUES(:username, :email, :pass, :passwordSalt, :firstname, :lastname, :gender, :country, :DOB)");
$keys = array_keys($other);
$columns = implode(",", $keys);
$colVals = implode(",:", $keys);
//l= $this->dbh->prepare("INSERT INTO `{$this->dbtable}` (`username`, `password`, `password_salt`, $columns) VALUES(:username, :password, :passwordSalt, :$colVals)");
//INSERT INTO MyGuests (firstname, lastname, email)cLUES ('John', 'Doe', 'john@example.com')
$sql = $this->dbh->prepare("INSERT INTO `{$this->dbtable}` (username,email,password,password_salt,name,lastname,created,gender,country,DOB) VALUES ('$username','$email','$pass','$saltedPass','$firstname','$lastname','$created','$gender','$country','$birthdate')");
print($sql);
foreach($other as $key => $value){
$value = htmlspecialchars($value);
$sql->bindValue(":$key", $value);
}
}
/* Bind the default values */
$sql->bindValue(":username", $id);
$sql->bindValue(":password", $saltedPass);
$sql->bindValue(":passwordSalt", $randomSalt);
$sql->execute();
return true;
}
}
So I need to use the variables from register.php in the class file. Can I just include it at the top or do I need to do something specific to the function?
Thanks. I'm focusing on the $sql line after else.
