HTTP Requests 87
.
1 $input = $request->input('products.0.name');
Determining If An Input Value Is Present
To determine if a value is present on the request, you may use the has method. The has method
returns true if the value is present and is not an empty string:
.
1 if ($request->has('name')) {
2 //
3 }
Retrieving All Input Data
You may also retrieve all of the input data as an array using the all method:
.
1 $input = $request->all();
Retrieving A Portion Of The Input Data
If you need to retrieve a sub-set of the input data, you may use the only and except methods. Both
of these methods accept a single array as their only argument:
.
1 $input = $request->only('username', 'password');
2
3 $input = $request->except('credit_card');
Old Input
Laravel allows you to keep input from one request during the next request. This feature is particularly
useful for re-populating forms after detecting validation errors. However, if you are using Laravel’s
included validation services, it is unlikely you will need to manually use these methods, as some of
Laravel’s built-in validation facilities will call them automatically.
