Upgrading to Phalcon 3 broke the existing site

My problem started right after I upgraded PHP to Version 7 and Phalcon to Version 3.

Problem

I m getting blank page, no error messages (Error is turned on), no `500 Internal server' error in console. The site used to work flawlessly before.

Is application made with previous version of phalcon not compatible with Phalcon 3?

I have following controller IndexController.php

namespace RealEstate\Property\Controllers;

use \Phalcon\Mvc\Controller;
use \Phalcon\Mvc\View;
use  RealEstate\Common\Models as CommonModels;

class IndexController extends Controller
{
   public function initialize(){
          //Code here
   }

   public function indexAction(){
       $this->view->setRenderLevel(View::LEVEL_ACTION_VIEW);

       $this->view->setVar("total_properties", $this->utils->getTotalProperties());    
       $this->view->pick("index");
       echo "HELLO WORLD";
   } 
}

The index action doesnot render anything, but yes HELLO WORLD is printed, so there seems there is no errors in code above that line.

My bootstrap index.php

namespace RealEstate;

use \Phalcon\Mvc\Application;
use \Phalcon\DI\FactoryDefault;
use \Phalcon\Loader;
use \Phalcon\Mvc\Router;
use \Phalcon\Mvc\View;

use \Phalcon\Events\Manager     as EventManager;
use \Phalcon\Assets\Manager       as Assets;
use \Phalcon\Mvc\Url        as UrlProvider;

  1. No errors on Server's error log
  2. Also have checked on Phalcon 3 on PHP 5.6. Same result

Thanks

double check all error logs you can find in /var/logs/ to see in which one exacly the error is placed. Cuz sometimes mine are placed at system.log or something like that ( i dont remmember exacltly )

Checked all error logs, no errors at all.

perhaps apache/nginx is screwing with you ? check their logs if everything is fine.

if its working fine start removing peice by peice the code until it start working and find the code block that fucks it.

And then we will see. There are too many stuff to copy/paste it in blank app of mine to test it.

Did you try making a micro site to see if Phalcon is even running?

Micro app is working even without changing any previous codes.

I think I solved this issue. The issue was in Module.php, the issue was in method

public function registerServices($di)
    {

        try{
            //Registering the view component
            $di->set('view', function() {
                $view = new View();
                $view->setViewsDir('../apps/modules/'.$this->module_name.'/views/');
                return $view;
            });

        }catch(\Phalcon\Exception $e){
            echo get_class($e), ": ", $e->getMessage(), "\n";
            echo " File=", $e->getFile(), "\n";
            echo " Line=", $e->getLine(), "\n";
            echo $e->getTraceAsString();
        }
    }

Where, $module_name is a property defined in class.

In above code $this->module_name was undefined. so I changed above method to -

public function registerServices($di)
    {
        $module = $this->module_name;

        try{
            //Registering the view component
            $di->set('view', function() use($module) {
                $view = new View();
                $view->setViewsDir('../apps/modules/'.$module.'/views/');
                return $view;
            });

        }catch(\Phalcon\Exception $e){
            echo get_class($e), ": ", $e->getMessage(), "\n";
            echo " File=", $e->getFile(), "\n";
            echo " Line=", $e->getLine(), "\n";
            echo $e->getTraceAsString();
        }
    }

I wondered why it was working in previous version of Phalcon

On previous to 3.0 when you used $this, on the closure used to define the service on the DIC, it was refering to the class where you was working on. Now, when you refer to $this inside the closure you are refering to the DI itself. Thats why. I had to change all my definitions too :(
