Laravel route with parameters

Question

Am using laravel route for approving some form from email. So i have encrypted some variables and created link which is like

Answer 1

Usually I use two ways:

1º way:

The route:

Route::get('approveRequest', 'ApproveController@approve');

The controller:

public function approve (Request $request) {
    $var1 = $request->input('var1');
    $var2 = $request->input('var2');
    
    // (...) do something with $var1 and $var2
}

2º way:

The route:

Route::get('approveRequest/{var1}/{var2}', 'ApproveController@approve');

The controller:

public function approve ($var1, $var2) {
    
    // (...) do something with $var1 and $var2: they already have a instance
}

Answer 2

There are many methods to do this.

Method 1

If you make the url like below:

<a href="http://localhost/travel/tr/approveRequest/<?=$Encoded_travelRq_id?>/<?=$Encoded_emp_gslab_id?>/<?=$Encoded_iv?>">Approve</a>;

You can make route with parameters as like below.

 Route::get('approveRequest/{par1}/{par2}/{par3}', 'ApproveController@approve');

And in your function get the respective parameter as following:

public function approve($par1,$par2,$par3,) 
{
     $id = $par1;
     $gsID = $par2;
     .... and so on for all your variables.
 }

Method 2 use request method:

If your url is like:

  <a href="http://localhost/travel/tr/approveRequest?id=<?=$Encoded_travelRq_id?>&gsID<?=$Encoded_emp_gslab_id?>&decrypt<?=$Encoded_iv?>/">Approve</a>;

Then define Route Like:

   Route::post('approveRequest', 'ApproveController@approve');

Then in your controller function you get parameters as below:

Use Request after the namespace in youe controller class

            namespace App\Http\Controllers;
            use Illuminate\Http\Request;

            class SomeClassController extends Controller {

                public function approve(Request $request) 
               {
                 $id = $request->id;
                 $gsID = $request->get('gsID');
                 .... and so on for all your variables.
                }
             }

Answer 3

Simply write a GET route to approveRequest :

Route::get('approveRequest', 'ApproveController@approve');

Because you are using URL parameters, you can simply get them in the approve() function like this

public function approve(Request $request) 
{
     $id = $request->id;
     $gsID = $request->get('gsID');
     .... and so on for all your variables.
}

With this approach the order of parameters does not matter.
