未定义的变量：gcount Laravel 4

Question

I'm having trouble with this variable. After filling up the details on the form and by clicking the reserve button, this error would come up. 'Unidentified variable: gcount'. I have included the necessary '->with' on the controller part but still, it shows the error. What seems to be the problem here?

    @extends('layouts.master')

     {{ Form::open(['url'=>'flight/onewayflightfillup']) }}

I'll just include my routes, the error might come from there.

routes.php

Route::post('flight/onewayflightterms','OnewayflightController@onewayflightfillup');
Route::post('flight/onewayflightfillup','OnewayflightController@onewayflightshow')

Answer 1

The problem is that line:

return View::make('content.onewayflightfillup')->withErrors($validator);

You don't pass here gcount . You should change it into:

return View::make('content.onewayflightfillup')->withErrors($validator)->with(['gcount'=>$guestcount]);

and obviously you need to add $guestcount= $children+$adult+$infant; before that the same as you did in the first function
