Hi,

All cases i find about middleware explain it through users, user roles, permissions etc. Does anyone knows an example on how to use middleware only to break down an url into variabls and pass that through to the function called?

For example, if you have:

Route::get('foo/{param1}/{param2}/thing-{thing1}/thing-{thing2}', ['uses'=>'FooController@fooByParamAndThings']);
Route::get('bar/{param1}/{param2}/thing-{thing1}/thing-{thing2}', ['uses'=>'BarController@barByParamAndThings']);

You can make the functions in the two controllers:

FooController:

public function fooByParamAndThings($param1,$param2,$thing1,$thing2){
        if($param1 = something){
                $params  = $param1.$param2;
        }
        if($thing1= somethingelse){
                $things = $thing1.$thing2;
        }

        $foo= \App\Foo::where('param', $param)->where('thing', $thing)->firstOrFail();

        return view('foo', ['foo'=>$foo]);
    }

BarController:

public function barByParamAndThings($param1,$param2,$thing1,$thing2){
        if($param1 = something){
                $params  = $param1.$param2;
        }
        if($thing1= somethingelse){
                $things = $thing1.$thing2;
        }

        $bar= \App\Bar::where('param', $param)->where('thing', $thing)->firstOrFail();

        return view('bar', ['bar'=>$bar]);
    }

This should work.

But:

Wouldn't it be much better to use a ParamThings middleware that performs all the actions on the params and things, and only passes the results to the functions? now the actions on that params and things are duplicate in the code.

But how to get the url variables to the middleware, and how to pass the $params and $things to the function?
