Help creating new pages in ACP

[FounderSim]

I cant seem to find any proper documentation on how to create modifications for mysidia. Here's what I have tried so far and can't figure out.

I have modified the class/class_page.php get_page to add my :EXPLORE: page the list of ACP pages if its even required.

I have created my explore.php page following the flow of other pages. To keep it simple, i only created the content first to see if it was even going to work which it didnt.

	public function add(){
	    $mysidia = Registry::get("mysidia");
		$document = $mysidia->frame->getDocument();	
			
		$document->setTitle($mysidia->lang->explore_title);
		$exploreForm = new Form("addform", "add", "post");
		$exploreForm->buildComment("<u><strong>Add new status:</strong></u>")
		               ->buildComment("Status Description: ", FALSE)->buildTextField("textDesc")
					   ->buildComment("Status Chance %: ", FALSE)->buildTextField("textDescPerc")
					   ->buildComment("<b>Add Explore Pet</b>")
					   ->buildDropDownList("adopt", "AdoptTypeList")
		               ->buildComment("Pet %: ", FALSE)->buildTextField("textPetPerc")
					   ->buildComment("<b>Add Explore Item:</b>")
					   ->buildDropDownList("item", "ItemList")
		               ->buildComment("Item %: ", FALSE)->buildTextField("textPetPerc")					   
					   ->buildComment("<b>Coin % Chance: </b>")
					   ->builtComment("Coin Low Amount", FALSE)->buildTextField("textCoinLow")
					   ->buildComment("Coin High Amount: ", FALSE)->buildTextField("textCoinHigh")
					   ->buildButton("Modify Explore", "submit", "submit");
		$document->add($exploreForm);
	}

I found i had to build my own itemList form helper as there was not one already made so i did so in the class_formhelper.php

	/**
     * The buildItemList method, builds a dropdown list for available items.
	 * @param String  $name
     * @access public
     * @return DropdownList
     */		
	public function buildItemList($name){
        $mysidia = Registry::get("mysidia");
		$itemList = new DropdownList($name);
	    $iids = $mysidia->db->select("items", array("id"))->fetchAll(PDO::FETCH_COLUMN);
		$inames = $mysidia->db->select("items", array("items"), "1 ORDER BY id")->fetchAll(PDO::FETCH_COLUMN);
	    $itemList->add(new Option("No Item Selected", "none"));
	    $itemList->fill($inames, $iids);
		return $itemList;
	}

so since I could not get the page to be displayed at myurl.com/adminacp/explore/add

I decided i would just add the method to another page to see if that was the problem. So i threw my add method into the image.php admin class and went to myurl.com/adminacp/image/add and the same problem continues.

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, blahblahblah and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

I am guessing that i have to somehow register the files or methods before actual using them?

Will the same concept of creating an acp file apply for creating a player file
