php - I am unable to handle SSH Connection Error Anyway -


i'm trying handle runtimeexception connect vps through ssh.

here's code connect vps through ssh. 

$server_ip = input::get('server_ip'); $password = input::get('password');  $validator = validator::make(     ['server_ip' => $server_ip],     ['server_ip' => 'ip|required|unique:servers'],     ['password' => $password],     ['password' => 'required|confirmed'] );  if(!$validator->fails()) {     config::set('remote.connections.production.host',$server_ip);     config::set('remote.connections.production.username','root');     config::set('remote.connections.production.password',$password);     config::set('remote.connections.production.root','/');      $command = 'mysql --version';      $connection_status = ssh::run($command, function($line)     {         $this->output = $line.php_eol;     });      if(!$connection_status)         return $this->output;     else         return view('dashboard.add_server'); } else     return "validation failed...";

it's written in laravel. in case, if error ssh connection, should redirect me view named add_server. but, i'm getting exception instead of redirection. here's errror every time instead of redirection.

enter image description here

what want is, if there error connection vps through ssh, should redirect me view named add_server

let me know what's wrong code.

try {     $connection_status = ssh::run($command, function($line)     {         $this->output = $line.php_eol;     });      if(!$connection_status)         return $this->output; } catch(\runtimeexception $e) {     return view('dashboard.add_server'); }

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
