General developer forum

All,

I've been working on developing a Lesson Plan module for Moodle as part of a project. Recently, I ran into problems where I recieved a "Cannot create new instance of <module name> ..." and I'm redirected to a view.php ID.  After going in and doing some echo() debugging, I came up with the following variable definitions that my mod.html/php is passing to mod.php....

First, the code snippet that I changed for debugging purposes...
==================================
 case "add":
                $return = $addinstancefunction($mod);
                if (!$addinstancefunction($mod))  // shouldn't matter
        {
            echo "Vars"; // I used this as a marker flag //
            echo $mod; // prints out "Object" thanks to the forced type... //
            echo "$addinstancefunction($mod)"; // same as $return; returns "plans_add_instance(Object)" //
            echo "$_POST"; // returns "Array" //
            echo"$Array"; // returns nothing? //
            echo "\"" . $return . "\""; // returns "" //
                    if (file_exists($moderr))
            {
                        $form = $mod;
                        include_once($moderr);
                        die;
                    }

==================================

Has anyone else developed a module that communicates through mod.php that might be able to offer any pointers?  Anyone have a clear roadmap for the mod.php case-switch in the sky?  Anyone have some examples they can let me see?

Thanks, all.
