Question

So I have library called Engine.php and what it does basically is running

example.com/controller/method/value

So for example if I have

example.com/category/images

it runs the method called “images”. But I don’t want to add to the code for every single category. I want the method to be a variable (so that I will make it work with db later).

How can I achieve this without changing the Engine? The problem is – some of the pages don’t have categories at all. And I don’t want to rewrite the Engine itself.

Can I somehow do this in the controller? For example:

I’m entering controller called “category” and if method is set, it searches for this method within the controller (”category”).

This is what part of my Engine.php looks like:

    if (isset($url_output[1])) {
        if (isset($url_output[2])) {
            if (method_exists($controller,$url_output[1])) {
                $controller->{$url_output[1]}($url_output[2]);
            } else {
                $this->error();
            }
        } else {
            if (method_exists($controller,$url_output[1])) {
                $controller->{$url_output[1]}();
            } else {
                $this->error();
            }
        }
      }

So basically, as you can see:

$controller->{$url_output[1]}();

$url_output[1] = the name of the method in controller named $url_output[0].

What I want is:

public function $category() {
echo $category
}

You know what I mean?

Answer 1

why don’t you make url like this

example.com/category/index/images

where index is a predefined function for category controller and images will be passes as first parameter to index function.

Second option, bypass the index function in url.

if (isset($url_output[1])) {
    if (method_exists($controller,'index')) {
        $controller->index($url_output[1]);
    } else {
        $this->error();
    }
}

class Category
{
    function index($category)
    {

    }
}

use like this: example.com/category/images
