how to call a function inside a controller in opencart - php

Question

i have a controller that have with in let's say thingy/stuff directory
<?php public function index() { /*thingy stuff */ }
public function anotherfunction() {/*other thingy stuff*/} ?>
i see tthe url like index.php?route=thingy/stuff&var=dd
what i want is to call an $.post to this function inside that controller
so it uses another template file thingy.tpl and return html to use
what the URL should like ??
i searched for hours ans it sounds like there is no development documentation for open-cart out there

Answer 1

let's say you have a controller called "stuff" under the thingy folder and a function called "my function" within that class, that looks like this:
class ControllerThingyStuff extends Controller {
public function index() {
// Some code
}
public function myfunction() {
// Your code
}
}
if you want to directly communicate with this function using the URL you can add the function name to the end of the route parameter "route=thingy/stuff/myfunction& ..." and load the thingy.tpl inside the function and return it after rendering:
// some code
$this->template = 'template/product/thingy.tpl';
...
$this->response->setOutput($this->render());
if are using the open cart 1.5 and you want to use jQuery AJAX with JSON then you'll need to import the JSON library before rendering:
$this->template = 'thingy/stuff/thingy.tpl';
$json['output'] = $this->render();
$this->load->library('json');
$this->response->setOutput(Json::encode($json));
take a look at the checkout page to get some ideas, the default open cart 1.5 template uses the same technique to load the templates for each section.

It's added to the route if it's not index, which it is by default, for example
<?php
class ControllerThingyStuff extends Controller {
public function index() {
// This is called with route=thingy/stuff or thingy/stuff/index
}
public function something() {
// This is called with route=thingy/stuff/something
}
}
