Topic: Controllers in MVC

[markyoung1984]

In an MVC environment, what should a controller be like?  Should it be a long series of switch statements?  Should it be an object or some description?  I just don't know and its confusing me.

A basic front controller could simply be a series of conditions within a switch. A more robust front controllershould attempt to resolv urls to objects / methods.

I do use objects in my code.  I am relating GET variables to objects but within a switch statement.  Is that how you would do it?

No. A switch statement would meen its hard coded. Everytime you add a new action controller you would need to update the switch.

A simple example of doing it dynamically (Not tested, just a demo).

Code: [Select]

<?php

  $controller = $_GET['c'];
  $action = $GET['a'];

  if (file_exists("controllers/$controller.class.php")) {
    include "controllers/$controller.class.php";
    $obj = new $controller;
    if (is_callable(array($obj, $action))) {
      $obj->$action();
    }
  }

?>
