I'm using this class code to insert data into the database:
<?php
Class User
{
private $error = "";
public function signup($post)
{
$data = array();
$data['name'] = trim($_POST['name']);
$data['email'] = trim($_POST['email']);
$data['pass'] = trim($_POST['pass']);
$pass2 = trim($_POST['pass2']);
if(empty($data['email']) || !preg_match("/^[0-9a-zA-Z_-]+#[0-9a-zA-Z_-]+.[0-9a-zA-Z_-]+$/", $data['email']))
{
$this->error .= "Please enter a valid Email <br>";
}
if(empty($data['name']) || !preg_match("/^[a-zA-Z]+$/", $data['name']))
{
$this->error .= "Please enter a valid Name <br>";
}
if($data['pass'] !== $pass2)
{
$this->error .= "Password dont match <br>";
}
if(strlen($data['pass']) < 4)
{
$this->error .= "Password must be at least 4 character long <br>";
}
if($this->error == "")
{
$data['rank'] = "customer";
$data['url_address'] = $this->get_random_string_max(60);
$data['date'] = date("Y-m-d H:i:s");
$query = "INSERT INTO users (url_address, name, email, pass, date, rank) VALUES (:url_address, :name, :email, :pass, :date, :rank)";
$db = Database::getInstance();
$result = $db->write($query, $data);
if ($result) {
header("Location:" . ROOT . "login");
die();
}
}
}
private function get_random_string_max($length)
{
$array = array(0,1,2,3,4,5,6,7,8,9,'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z');
$text = "";
$length = rand(4, $length);
for ($i=0; $i>$length;$i++) {
$random = rand(0, 61);
$text .= $array[$random];
}
return $text;
}
}
this is the database Class:
<?php
Class Database
{
public static $con;
public function __construct()
{
$dsn = 'mysql:hostname=localhost;dbname='. DB_NAME;
$options = array(
PDO::ATTR_PERSISTENT => true,
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
);
try {
return $db = new PDO($dsn, DB_USER, DB_PASS, $options);
} catch (PDOException $e) {
die($e->getMessage());
}
}
public static function getInstance()
{
if(self::$con) {
return self::$con;
}
return $instance = new self();
}
public function read($query, $data = array())
{
$stmt = self::$con->prepare($query);
$result = $stmt->excute($data);
if ($result) {
$data = $stmt->fetchAll(PDO::FETCH_OBJ);
if(is_array($data)) {
return $data;
}
}
return false;
}
public function write($query, $data = array())
{
$stmt = self::$con->prepare($query);
$result = $stmt->excute($data);
if ($result) {
return true;
}
return false;
}
}
I'm using MVC and this is the signup controller page and database class.
pass2 is retyped password in the form.
but the data not inserting into the database and not redirecting to the login page.
and
PDO::ERRMODE_EXCEPTION
not showing any errors.
what is the problem?

Answer 1

In Database Class You have an error in writing the function excute() in line:
$result = $stmt->excute($data);
it should be execute()
$result = $stmt->execute($data);
