Laravel Route how to convey the parameters

Laravel routes: learn how to pass parameters w/ an example.

Passing Parameters to a Route

Parameters can be passed to a route by placing them in the URL or as route attributes. The parameters can then be used to perform certain tasks and can be retrieved in the controller or the route file itself. In this article, we will look at how to pass parameters to a route in a Laravel application.

Passing Parameters as URL

The most common approach is to pass parameters as a URL segment. To do this, you can define a route that contains the parameter as part of its URL definition. The parameter can be specified as a named parameter in the URL, or as an optional parameter. Let's look at an example:

Route::get('users/{id}', 'UserController@show'); // Named Parameter
Route::get('users/{id?}', 'UserController@show'); // Optional Parameter

In the example above, we have defined a route that takes a parameter as part of its URL definition. The parameter is specified as a named parameter, which means that it is required for the route to be matched. If the parameter is not specified, the route will not be matched. The parameter can also be specified as an optional parameter, which means that it is not required for the route to be matched.

Once the parameter is defined in the URL, it can be accessed in the controller or the route file using the $request object. The parameter can then be used to perform certain tasks, such as retrieving data from the database or performing calculations.

Passing Parameters as Route Attributes

Parameters can also be passed to a route as route attributes. To do this, you can define a route with an array of attributes as the second parameter. The attributes can then be accessed in the controller or the route file using the $request object. Let's look at an example:

Route::get('users', 'UserController@show', [
    'id' => '12345'
]);

In the example above, we have defined a route that takes an array of attributes as its second parameter. The attributes can then be accessed in the controller or route file using the $request object. The attributes can then be used to perform certain tasks, such as retrieving data from the database or performing calculations.

In this article, we have looked at how to pass parameters to a route in a Laravel application. We have seen that parameters can be passed as URL segments or as route attributes. We have also seen how to access the parameters in the controller or the route file using the $request object.
