Getting Statement couldn't be produced with sql in zend2? - php

Question

this is my function in my model:
public function user_login($getData,$session_id){ // manage the user's login
$email = $getData['login_email'];
$password = $getData['login_password'];
$select = $this->adapter->query("select count(*) as counter from users where email = '$email' and password = '".md5($password)."'");
$results = $select->execute();
if ($results->current()['counter'] == 1 ){
$update = $this->adapter->query("update users set session_id = '".$session_id."' where email = '".$email."'");
$update_session = $update->execute();
return 1;
}else{
return 0;
}
}
When I executed the count query it works and im also using this method to get values from queries or to insert data in db. but now i want to do a simple update, which does not work for some reason. I don't know why ? why i'm getting this message ?
UPDATE: this is the content of the Module.php file from my module name folder:
namespace Application;
use Zend\Mvc\ModuleRouteListener;
use Zend\Mvc\MvcEvent;
class Module
{
public function onBootstrap(MvcEvent $e)
{
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
}
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
public function getAutoloaderConfig()
{
return array(
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
),
),
);
}
public function getServiceConfig() {
return array(
'factories' => array(
'Application\Model\UsersTable' => function($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$table = new Model\UsersTable($dbAdapter);
return $table;
},
),
);
}
}

Had the same issue, found solution here.
Probably unbuffered query?
$statement = $adapter->query("SELECT ...");
$result = $statement->execute();
$result->buffer();
// validate your result
