Using function from controller in anothercontroller

Hello World!

I got two Controllers: JsonController and MapController.

In the JsonController I got a public function namend "getJson($param,$id)". This functions calls other private function, depending on the $param.

My MapController needs information about some planets, so I use

    $jsonController = new \Pegasus2540\Frontend\Controllers\JsonController();

    $json = $jsonController->getJson("planets", 1);

in the showAction() of my MapController to get the information.

My getJson() function looks like this

public function getJSON($param, $id) {
    echo "You would like to get: ".$param."-".$id;
    switch ($param) {
            $data = $this->getPlanets($id);
            $data = $this->getSolarsystem($id);

    echo json_encode($data);
    return json_encode($data);

Now, when I call the map in my browser, I expect something like "You would like to get planets-1" and my json.

But it seems like it doenst work. No echo, no json.

Are you sure your routes are working? I tested your exact scenario with two random controllers and it works. Perhaps try adding exit; after your first echo in getJson method.

In general a better solution would be to move the code from your json controller into library/helper file or a model if it is db related. This way you will be able to use it anywhere you want without violating MVC principles.


Yes, I am sure. When I call the Jsoncontroller like this MYURL/json/get/planets/1 it works.

I will try the library/helper variant. :)

Create service and put getJSON there. And then access this service in your controller. You shouldnt call method from one controller in other controller.

Okay, I changed it to this now:

I created a folder called library inside the root of my applicataion. there is a connector.php:

namespace Pegasus2540\Library;

class Connector {
public function hello($string) { return "Hello ".$string; } }

In my Module.php I register the Namespace like this:

        'Pegasus2540\Frontend\Controllers' => __DIR__.'/controllers/',
        'Pegasus2540\Library'    => '/PATH TO APP/game/library/',

In my MapController:

    $c = new \Pegasus2540\Library\Connector;
    echo $c->hello("World");

Now I get a WhiteScreen. No view is loaded and no echo.

I took in the apache error.log and found this.

Unable to load dynamic library '/usr/lib/php5/20121212/' - /usr/lib/php5/20121212/ undefined symbol: php_pdo_get_dbh_ce in Unknown on line 0

Sounds like a clue to me, but googling this error only show me solutions at installing phalcon, but I have already installed phalcon (and it works).

I will google again for this error until I find a solution. I think outsourcing the library will do it, so thanks for your help! :) should be loaded AFTER pdo, database extensions etc. Best load as last extension. Also this can mean that you dont have pdo extension loaded.
