How can I define a route differently if parameter is not integer

Question

I am using Laravel 5 and working on my local. I made a route with a parameter of {id} and another route with a specific name like so :

Route::get(\'contacts/         


        

Answer 1

Just add ->where('id', '[0-9]+') to route where you want to accept number-only parameter:

Route::get('contacts/{id}', 'ContactController@get_contact')->where('id', '[0-9]+');
Route::get('contacts/new', 'ContactController@new_contact');

Answer 2

There is also the possibility to just switch those around, because route file will go through all lines from top to bottom until it finds a valid route.

Route::get('contacts/new', 'ContactController@new_contact');
Route::get('contacts/{id}', 'ContactController@get_contact');

If you want to restrict that route to pure numbers, the marked solution is correct though.

Just adding it here, I know it is quite old ;)

Answer 3

Although the accepted answer is perfectly fine, usually a parameter is used more than once and thus you might want to use a DRY approach by defining a pattern in your boot function in the RouteServiceProvider.php file located under app/Providers (Laravel 5.3 and onwards):

 /**
 * Define your route model bindings, pattern filters, etc.
 *
 * @return void
 */
public function boot()
{
    Route::pattern('id', '[0-9]+');

    parent::boot();
}

This way, whereever you use your {id} parameter the constraints apply.

Answer 4

A simple solution would be to use an explicit approach.

Route::get('contacts/{id:[0-9]+}', 'ContactController@get_contact');
Route::get('contacts/new', 'ContactController@new_contact');
