weird pdo sql update behaviour - php

Question

I have a sql UPDATE query in PDO that should update a name and a permissions string.
But instead it just places the id of that row inside all columns.
Here is my code:
public function saveRole($roleID, $name, $permissions)
{
$sql = "UPDATE roles SET name = :name, permissions = :permissions WHERE id = :id";
//this one sets a string variable in the PDO wrapper class
PDO::setSQL($sql);
//this one sets an array inside the PDO wrapper class
PDO::setData([
'name' => $name,
'permissions' => $permissions,
'id' => $roleID,
]);
PDO::execute();
return PDO::getResponse(true);
}
As you see, I've written a wrapper for PDO, which looks like this:
static function execute($sql = null, $data = null, $fetchmode = \PDO::FETCH_OBJ)
{
//check if data and SQL are set in function call, if so, use function call params, if not use class params ($this->SQL & $this->data)
self::connect();
try
{
$stmnt = self::$con->prepare(self::$sql);
$stmnt->setFetchMode($fetchmode);
if (sizeof(self::$data) > 0)
{
foreach (self::$data as $key => $value)
{
$stmnt->bindParam(':' . $key, $value);
}
}
$stmnt->execute();
self::$stmnt = $stmnt;
self::$data = [];
self::$sql = '';
self::$lastResponse = new pdoReturn(true, $stmnt);
return;
} catch (\PDOException $exception)
{
self::$data = [];
self::$sql = '';
self::$lastResponse = new pdoReturn(false, $exception);
return;
}
}
function setSQL($sql) {
if (!is_string($sql))
return false;
if (strlen($sql) == 0)
return false;
$this->sql = $sql;
return true;
}
function setData($data) {
if (!is_array($data))
return false;
$this->data = $data;
return true;
}

For the immediate fix, change
$stmnt = self::$con->prepare(self::$sql);
$stmnt->setFetchMode($fetchmode);
if (sizeof(self::$data) > 0)
{
foreach (self::$data as $key => $value)
{
$stmnt->bindParam(':' . $key, $value);
}
}
$stmnt->execute();
to
$stmnt = self::$con->prepare(self::$sql);
$stmnt->setFetchMode($fetchmode);
$stmnt->execute(self::$data);
