Route Parameters laravel issue - laravel

Question

I simply made this but /maps/{category}/{map} does not work correctly.
putting anything on {category} showing same result.
/maps/php/1
/maps/laravel/1
I want to show a result when category's name and map's id exactly matches otherwise redirect to homepage.
My route
Route::get('/maps/{category}', 'MapsController#index');
Route::get('/maps/{category}/{map}', 'MapsController#show');
My controller
public function show(Category $category, Map $map)
{
return view('maps.show', compact('map'));
}
My blade template
{{ $map->title }}

Answer 1

Swap over the routes in your routes file so that the more specific one is first.
Route::get('/maps/{category}/{map}', 'MapsController#show');
Route::get('/maps/{category}', 'MapsController#index');

Answer 2

Firstly, there is no need to swap order of routes if you are using 5.4, since I started with 5.4 to use laravel i cannot say anything for previous versions.
If you you want to filter asked map if it matches given category, you can use "whereHas" method with eloquent if you defined relationship between category and map.
"One To Many (Inverse)" relationship is what you need to use, check here: https://laravel.com/docs/5.4/eloquent-relationships#one-to-many-inverse
And querying relationship is what you need to know, check here: https://laravel.com/docs/5.4/eloquent-relationships#querying-relationship-existence
How your relationship should look like in Map model:
/**
* Get the category that owns the map.
*/
public function category()
{
return $this->belongsTo('App\Category');
}
An example code:
public function show($category, $map)
{
$map = Map::whereHas('category',function($query) use($category){
$query->where('id', $category);
});
return view('maps.show', compact('map'));
}

Answer 3

Route::get('/maps/{category}', 'MapsController#index');
is a more generalized route so it matches more than
Route::get('/maps/{category}/{map}', 'MapsController#show');
You should list the show route first.
To match an exact model attribute (i.e. name), you should customize the resolution logic the router uses in the route service provider boot method. For example:
Route::bind('category', function ($value) {
return App\Category::where('name', $value)->first();
});
Route::bind('map', function ($value) {
return App\Map::where('id', $value)->first();
});

Answer 4

public function show($category,$map)
{
$category = App\Category::where('category_name',$category);
$map_id =App\Map::where('map_id',$map);
if(!empty($category) && !empty($map_id))
{
return view('maps.show', compact('map'));
}
else
{
return view('homepage', compact('map'));
}
}
