You may access all user input with a few simple methods. You do not need to worry about the HTTP verb used for the request, as input is accessed in the same way for all verbs.
Retrieving An Input Value
$name = Input::get('name');
Retrieving A Default Value If The Input Value Is Absent
$name = Input::get('name', 'Sally');
Determining If An Input Value Is Present
if (Input::has('name'))
{
//
}
Getting All Input For The Request
$input = Input::all();
Getting Only Some Of The Request Input
$input = Input::only('username', 'password');
$input = Input::except('credit_card');
Some JavaScript libraries such as Backbone may send input to the application as JSON. You may access this data via Input::get like normal.
All cookies created by the Laravel framework are encrypted and signed with an authentication code, meaning they will be considered invalid if they have been changed by the client.
Retrieving A Cookie Value
$value = Cookie::get('name');
Attaching A New Cookie To A Response
$response = Response::make('Hello World');
$response->withCookie(Cookie::make('name', 'value', $minutes));
Creating A Cookie That Lasts Forever
$cookie = Cookie::forever('name', 'value');
You may need to keep input from one request until the next request. For example, you may need to re-populate a form after checking it for validation errors.
Flashing Input To The Session
Input::flash();
Flashing Only Some Input To The Session
Input::flashOnly('username', 'email');
Input::flashExcept('password');
Since you often will want to flash input in association with a redirect to the previous page, you may easily chain input flashing onto a redirect.
return Redirect::to('form')->withInput();
return Redirect::to('form')->withInput(Input::except('password'));
Note: You may flash other data across requests using the Session class.
Retrieving Old Data
Input::old('username');
Retrieving An Uploaded File
$file = Input::file('photo');
Determining If A File Was Uploaded
if (Input::hasFile('photo'))
{
//
}
The object returned by the file method is an instance of the Symfony\Component\HttpFoundation\File\UploadedFile class, which extends the PHP SplFileInfo class and provides a variety of methods for interacting with the file.
Moving An Uploaded File
Input::file('photo')->move($destinationPath);
Input::file('photo')->move($destinationPath, $fileName);
Retrieving The Path To An Uploaded File
$path = Input::file('photo')->getRealPath();
Retrieving The Size Of An Uploaded File
$size = Input::file('photo')->getSize();
Retrieving The MIME Type Of An Uploaded File
$mime = Input::file('photo')->getMimeType();
The Request class provides many methods for examining the HTTP request for your application and extends the Symfony\Component\HttpFoundation\Request class. Here are some of the highlights.
Retrieving The Request URI
$uri = Request::path();
Determining If The Request Path Matches A Pattern
if (Request::is('admin/*'))
{
//
}
Get The Request URL
$url = Request::url();
Retrieve A Request URI Segment
$segment = Request::segment(1);
Retrieving A Request Header
$value = Request::header('Content-Type');
Retrieving Values From $_SERVER
$value = Request::server('PATH_INFO');
Determine If The Request Is Using AJAX
if (Request::ajax())
{
//
}
Determining If The Request Is Over HTTPS
if (Request::secure())
{
//
}
