php - How to make Request default in Laravel 5.1 when none is given -

i using laravel 5.1 , need make default value when in field none given.

so view looks like:

<form name="search" method="post" action="/s">     country<input name="country" type="text">     field<input name="field" type="text">     <button type="submit" type="button">search</button>     <input name="_token" value="{{ csrf_token() }}" type="hidden"> </form> 

the controller looks like:

public function extendedpost(request $request){         $data = $request->all();         $request->input('field', 'random');         dd($data); } 

in laravel 5.1 documentation have:

you may pass default value second argument input method. value returned if requested input value not present on request:

$name = $request->input('name', 'sally'); 

so when have in "field" have:

array:21 [▼   "country" => ""   "field" => "dddd"   "_token" => "xemi" ] 

but when "field" empty have

 array:21 [▼       "country" => ""       "field" => ""       "_token" => "xemi"     ] 

instead of

 array:21 [▼       "country" => ""       "field" => "random"       "_token" => "xemi" 

thanks helping me

the function input not updating $request check if given attribute not present in request if return default value passed in second argument, try use has() check if attribute present in request , update request manually :

if( $request->has('field')) {     $request->field = 'random'; } 

note : has method returns true if value present , not empty string.

hope helps.
