Setting up user login session code in MVC.

I am NOT getting my populated array results printed to page.

using ...

controllers/sessions.php

<?php

  include(MODEL_PATH.'user.php');


switch ($route['view']) {

  case "new":

  break;

  case "create":
 echo OK; 

  print_r($params['user']);

  break;

}

?>

the page i am routing to (from sessions/new to sessions/create)
http://localhost/localFixers/sessions/create

echos ...
OK
for

  case "create":
 echo OK;

yet prints nothing for

print_r($params['user']);

I Did a var dump which shows the [user] Array is being populated.

index.php

<?php

  // starts a session
  	session_start();

  // Holds the configuration for app, CONSTANTS ect...
	// Good idea to look inside.
	// * change the directory of your app in here
	// * edit your routes in here.
	// * edit database params in here.
	include('config.php');

die('<pre>'.print_r(get_defined_vars(), true).'</pre>');


  function dispatcher($routes)

AND SO ON for code

Array
(
[GLOBALS] => Array
(
[GLOBALS] => Array
RECURSION
[_POST] => Array
(
[user] => Array
(
[username] => User1
[password] => password
)

            )

How do I TEST/DEBUG code to see why the populated Array
is not displaying my array results on the page I have routes to?

sessions/create

should display

Array ([username] => User1 [password] => password )

    Hi anakadote

    Thanks for the reply!

    php code is printing out fine when finding posts $routes array
    http://localhost:8080/localFixers/posts

    but not when finding sessions $routes

    I am defining $params in index.php

    <?php

   // starts a session
	 session_start();

/**
	 * dispatches route
	 * @param array $routes
	 * @return array
	 */
	include('config.php');

  function dispatcher($routes)
  {
     // Requested URL
	  $url = $_SERVER['REQUEST_URI'];

  // Removes Apllication root from url
  $url = str_replace('/'.APP_ROOT.'/', '', $url);

	// holds the named captures, $_POST data
  $params = parse_params();

	// Removes query string from $url we don't need it anymore affect routes.
	$url = str_replace('?'.$_SERVER['QUERY_STRING'], '', $url);

	//  becomes true if $route['url'] matches $url
  $route_match = false;	

	// loops over $routes looking for a match
	foreach($routes as $urls => $route)
  {
		// if match found appends $matches to $params
		// sets $route_match to true and also exits loop.
	  if(preg_match($route['url'], $url, $matches))
	  {
		  $params = array_merge($params, $matches);
		  $route_match = true;
	    	break;
	  }
  }

	// if no route matched display error
	if(!$route_match) { exit('no route found'); }

	// include controller
  include(CONTROLLER_PATH.$route['controller'].'.php');

	if(file_exists(VIEW_PATH.'layouts'.DS.$route['controller'].'.php'))
	{
			// includes controller layout
	    include(VIEW_PATH.'layouts'.DS.$route['controller'].'.php');
	}
	else
	{
		// include default layout
	  include(VIEW_PATH.'layouts'.DS.'application.php');
	}

	// reset our flashs back to empty.
  $_SESSION['flash']['notice'] = '';
	$_SESSION['flash']['warning'] = '';

  }

dispatcher($routes);

/**
 * Return array of $_GET and $_POST data
 * @return array
 */
function parse_params()
{
  $params = array();

	if (!empty($_POST))
	{
	  $params = array_merge($params, $_POST);
	}

  if (!empty($_GET))
	{
	  $params = array_merge($params, $_GET);
	}

	return $params; 
}

?>

    I am defining $routes in config.php

    
<?php

/**
 * Holds the configuration for app, CONSTANTS ect...
 * Good idea to look inside.
 * change the directory of your app in here
 * edit your routes in here.
 */


   // routes url to controller and view

$routes = array(   
				   // posts
	               array('url' => '/^posts\/(?P<id>\d+)$/', 'controller' => 'posts', 'view' => 'show'),
				   array('url' => '/^posts\/new$/', 'controller' => 'posts', 'view' => 'new'),

      It's a lot to look over, but I don't see where $params['user'] is being set anywhere. What do you get when you try print_r($params) instead of this print_r($params['user']) ?

        well that prints

        Array ( [0] => sessions/create )

          RESOLVED

          Hey anakadote

          I replaced my index.php with the index.php I am using on my server and still had the same problem so I did a copy and paste of the text using note pad.

          NOW using ...

            case "create":

  //print_r($params['user']);

  print_r($params);
  break;

          I get what I need.

          Array ( [user] => Array ( [username] => User1 [password] => password ) [0] => sessions/create )

          I didn't see any difference in the index.php files yet Problem Solved.

          Thanks for your assistance!

          Oh and I found the TEST/DEBUG code I was asking about to test my code routes in case anyone needs it.

          I placed it in my index file like so ...

          		// if no route matched display error
		if(!$route_match) { exit('no route found'); }
print('controller: '.$route['controller'].' view: '.$route['view'].' id: '.$params['id']).'<br />';

          which gives

          controller: sessions view: create id:

          ' id: '.$params['id'] is blank right now because I am not connecting to the database yet to get
          user_id = '%s'

          cheers
