问题 I am using Laravel Framework version 4.1.21 and the "expire_on_close" option does not end the session in Chrome when the browser is closed.

问题 I am trying to find an elegant way in Eloquent and Laravel to say select * from UserTable where Age between X and Y Is there a between operator in Eloquent (I can't find it).

' AND ' . $ageTo . ''); Is there an actual Eloquent way (not raw) that deals with ranges? 回答1: $query-

问题 when use "Route::model" in routes.php Route::model('pizza', 'Pizza'); Route::get('edit/{pizza}', 'PizzaController@edit'); I receive error if "id" not found in DB, how to display custom message in this status? thanks, 回答1: By default, Laravel will throw a 404 error if the model binding fails.

问题 I have just installed a laravel project into my Home/public_html folder. I gave it a name, let's call it laravel for this purpose. So the template installed to Home/public_html/laravel and then I ran a composer install . I got a database password error. I fixed that, ran it again, and all went well.
