wish of those help Your best bet is to make a custom error page, and optionally create a custom error handler to alert you of the error. First, create a custom error page, just create a file in /path/to/project/config/error/error.html.php. Symfony will automatically use your error page instead of its own if it exists. class ProjectConfiguration extends sfProjectConfiguration
{
public function setup()
{
//...
$this->dispatcher->connect('application.throw_exception', array($this, 'listenToException'));
}
public function listenToException(sfEvent $event)
{
$handler = new myExceptionHandler($event);
$handler->doSomethingHere();
}
}
class myExceptionHandler
{
protected $event;
public function __construct(sfEvent $event)
{
$this->event = $event;
}
protected function getMailer()
{
return sfContext::getInstance()->getMailer();
}
public function notify()
{
$subject = 'Uncaught Exception';
$body = $this->event->getSubject();
$mailer = $this->getMailer();
$mailer->composeAndSend('root@yourserver.com', 'you@youremail.com', $subject, $body);
}
}

Handling MySQL Errors when using Ajax
Date : March 29 2020, 07:55 AM
fixed the issue. Will look into that further I would move all your error logic from jQuery to PHP. You can respond with a simple JSON object that can hold the status (success or error), code (if needed), message, and even data, if you want to provide specific results. For example, you make a request like this: $.ajax({
type: 'POST',
url: url,
data: $("#frmSurvey").serialize(),
success: function(result){
var json = $.parseJSON(result);
if(json.response.status == 'success') {
// do something
} else {
// look at message or code to perform specific actions
}
}
});
$result = array(
'response' => array(
'status' => 'error',
'code' => '1', // whatever you want
'message' => 'Could not connect to the database.'
)
);
echo json_encode($result);

Handling errors in PDO when MySQL query fails

I hope this helps you . Nope, it is not. Just like almost every PHP user, you have quite vague and uncertain idea on error handling. And the code mostly looks like a dummy code from sandbox example. Speaking of your current approach, frankly - it's just terrible. On a live site it will only scare an innocent user, while webmaster would have no idea what's going on. $dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
private function checkUser($user)
{
$stmt = $this->_PDO->prepare("SELECT 1 FROM users WHERE name=?");
$stmt->execute(array($user));
return $stmt->fetchColumn();
}
