Route Filtering with regex
Suppose, you’ve a route named Route::get(‘product/{id}’, [\App\Http\Controllers\ProductController::class,’view’]) and you want id to strictly to be a number. To achieve that you’ve to use Regex with an where() condition like below
Route::get('user/{name}', function ($name) {
//
})->where('name', '[A-Za-z]+');
Route::get('user/{id}', function ($id) {
//
})->where('id', '[0-9]+');
Route::get('user/{id}/{name}', function ($id, $name) {
//
})->where(['id' => '[0-9]+', 'name' => '[a-z]+']);
Define Regex in a RouteServiceProvider
We will use the previous route Route::get(‘product/{id}’, [\App\Http\Controllers\ProductController::class,’view’]), where you want to always use id as a number, then you can also specify it in the RouteServiceProvider. Just pase the below code in boot() method of your RouteServiceProvider.
Route::pattern('project_id', '[0-9]+');
parent::boot();
That’s all for today. Thanks for reading ?
