I recently moved to MariaDB, because since MySQL 5.6 it has been failing a lot for me.
MariaDB works flawlessly but, in a new project, I cannot insert data to the database with a PHP script. I can only insert manually. I have made no changes from scripts working with MySQL.
The INSERT statement is:
INSERT INTO participantes (nome, curso, email, equipe) VALUES (:nome, :curso, :email, :equipe);
And the script which should be inserting is:
$stmt = $this->dbh->prepare($this->SQL_INSERT);
$nome = $participante->nome();
$curso = $participante->curso();
$email = $participante->email();
$equipe = $participante->equipe();
$stmt->bindParam(':nome', $nome);
$stmt->bindParam(':curso', $curso);
$stmt->bindParam(':email', $email);
$stmt->bindParam(':equipe', $equipe);
$stmt->execute();
The "participante" functions return data to be used, with no problems. Everything is inside a try/catch block, which reports no exceptions.
My PDO class is as follows:
class Connection extends PDO {
private $dsn = 'mysql:host=localhost;port=3307;dbname=dacu';
private $usr = 'dacu';
private $pwd = 'my password';
public $handle = null;
function __construct() {
try {
if ($this->handle == null) {
$dbh = new PDO($this->dsn, $this->usr, $this->pwd);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$this->handle = $dbh;
return $this->handle;
}
}
catch (PDOException $e) {
throw new Exception('Não foi possível conectar-se ao banco de dados: ' . $e->getMessage());
}
catch (Exception $e) {
throw new Exception('Um erro não identificado ocorreu: ' . $e->getMessage());
}
}
}
And using controller->insert gives me:
Warning: PDO::prepare(): SQLSTATE[00000]: No error: PDO constructor was not called in C:\Webserver\Files\dacu\controller\EquipesController.php on line 25
I can post code on pastebin if necessary, just ask.

Check your connection, then try this way, its working fine:
//first you need a connection to mysql use this and replace the variables
try {
$dbh = new PDO('mysql:host=localhost;dbname='.$db_name.'', $user, $pass, array(
PDO::ATTR_PERSISTENT => true
));
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}
//then do the insert variable
$sql = 'INSERT INTO encomendas (`nome`, `user`, `id`, `email`) ';
$sql .= 'VALUES (:nome, :curso, :email, :equipe )';
$query = $dbh->prepare($sql);
//bindParam with your own variables
$query->bindParam(':nome', $varDoNome, PDO::PARAM_STR);
$query->bindParam(':curso', $varDoCurso, PDO::PARAM_STR);
$query->bindParam(':email', $varDoEmail, PDO::PARAM_STR);
$query->bindParam(':equipe', $varDaequipe, PDO::PARAM_STR);
//execute query
$query->execute()
;
