Answer 1

You need to add the parameter to the route. So, it should look like this:

Route::get('add/{slug}', 'HomeController@add');

And the add method:

public function add(Request $request, $slug)

Then value of the $slug variable will be Chilli Green Salad

Answer 2

You can do it like,

Route

Route::get('add/{data}', 'HomeController@add');

Controller

public function add(Request $request){
    // Access data variable like $request->data
}

I hope you will understand.

Answer 3

In your router.php :

Route::get('/add/{recipe}', 'HomeController@add'); // if recipe is required
Route::get('/add/{recipe?}', 'HomeController@add'); // if recipe is optional

In your `controller:

public function add(Request $request, $recipe) {
  // play with $recipe
}

Hope this will help!

Answer 4

Alter your url,add a get variabile

tableHtml += "<td><a href= '{{url('/add')}}/?slug=" + data.hits[i].recipe.label + "'> add to favotite</a></td>";

in your controller you use

public function add(Request $request)
{

echo $request->slug;

}

Answer 5

1. If you have your parameter attached to the URL after the question mark like

http://www.siteurl.com/someRoute?key=value

Your route for this controller will look something like this

public function controllerMethod(Request $request) {
$key = $request->key
echo $key;
}

2. If you have your parameter attached to the URL without question mark like

http://www.siteurl.com/someRoute/value

Your route for this controller will look something like this

Route::get('someRoute/{key}', $controller . 'controllerMethod');

You can get the value of this parameter in your controller function by passing the same name of variable in your controller method as you used in the route.

public function controllerMethod(Request $request, $key) {
echo $key;
}
