Getting an error while trying to get data out of a database based on id which i got from i button on a previous page. When i echo the id only it gives me the correct id but in the full query it gives me this error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY093]: Invalid parameter number: no parameters were bound' in
I found some SO answers on this but none of them solved the problem i had.
<?php
$fetch_article_info = $db->query("select * from news_article where id = :id");
$fetch_article_info->execute(array(':id' => $_GET['id']));
$list = $fetch_article_info->fetchAll(PDO::FETCH_ASSOC);
?>
Here are some of my public funtions in db.class which i think might be usefull
class Database{
private $host = DB_HOST;
private $user = DB_USER;
private $pass = DB_PASS;
private $dbname = DB_NAME;
// database handler
private $dbh;
private $error;
private $stmt;
public function __construct(){
// Set DSN
$dsn = 'mysql:host=' . $this->host . ';dbname=' . $this->dbname;
// Set options
$options = array(
PDO::ATTR_PERSISTENT => true,
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
);
// Create a new PDO instanace
try {
$this->dbh = new PDO($dsn, $this->user, $this->pass, $options);
}
// Catch any errors
catch (PDOException $e) {
$this->error = $e->getMessage();
}
}
public function bind($param, $value, $type = null){
if (is_null($type)) {
switch (true) {
case is_int($value):
$type = PDO::PARAM_INT;
break;
case is_bool($value):
$type = PDO::PARAM_BOOL;
break;
case is_null($value):
$type = PDO::PARAM_NULL;
break;
default:
$type = PDO::PARAM_STR;
}
}
$this->stmt->bindValue($param, $value, $type);
}
public function query($query){
$this->stmt = $this->dbh->prepare($query);
}
public function execute(){
return $this->stmt->execute();
}
public function resultset(){
$this->execute();
return $this->stmt->fetchAll(PDO::FETCH_ASSOC);
}
public function single(){
$this->execute();
return $this->stmt->fetch(PDO::FETCH_ASSOC);
}

You aren't passing into your execute function. See below.
$db->execute(array(':id' => $_GET['id']));
$list = $db->resultset(PDO::FETCH_ASSOC);
print_r($list);
// db.php file
public function execute($params){
return $this->stmt->execute($params);
}
public function resultset(){
// $this->execute();
return $this->stmt->fetchAll(PDO::FETCH_ASSOC);
}
