Laravel 4, ->withInput(); = Undefined offset: 0 - php

Question

I have had a lengthy search both here and the Laravel forums, but i can't find an answer to this problem. ->withInput() coughs up an Undefined offset: 0.
For Context:
Controller
public function getJobs()
{
$position_options = DB::table('jposition')->lists('friendly','id');
$category_options = DB::table('jcategory')->lists('friendly','id');
$location_options = DB::table('jlocation')->lists('friendly','id');
$result = $query->get();
return View::make('jobsearch.search', array('position_options' => $position_options, 'category_options' => $category_options, 'location_options' => $location_options))->withInput();
}
View
<form action="{{ action('JobsearchController#getJobs') }}" method="post">
<div class="row">
<div class="large-8 columns">
<input type="text" name="realm" placeholder="Keywords/Skills" />
</div>
<div class="large-4 columns">
{{ Form::select('category', $category_options , Input::old('category')) }}
</div>
</div>
<div class="row">
<div class="large-4 columns">
{{ Form::select('location', $location_options , Input::old('location')) }}
</div>
<div class="large-4 columns">
{{ Form::select('type', $position_options , Input::old('type')) }}
</div>
<div class="large-4 columns">
<input type="submit" value="Search" style="width:100%; padding-top: .5rem;
padding-bottom: .5rem;" class="button border-btn" />
</div>
</div>
</form>
Now according to the documentation there should not be an issue, and the page loads fine if the ->withInput(); is removed.
The end goal is to roll in the answer that i received from my previous question Undesired result from db:raw and have a single page that loads the "Filtering" form and displays the relevant results on the reload and remembers the selections in the form.
Thanks in advance.
UPDATE:
Following a comment i have updated the controller and routes, still same result:
routes.php
Route::get('jobs/search', 'JobsearchController#getSearch');
&
Route::post('jobs/search', 'JobsearchController#getJobs');
Controller
public function getSearch()
{
$position_options = DB::table('jposition')->lists('friendly','id');
$category_options = DB::table('jcategory')->lists('friendly','id');
$location_options = DB::table('jlocation')->lists('friendly','id');
return View::make('jobsearch.search', array('position_options' => $position_options, 'category_options' => $category_options, 'location_options' => $location_options));
}
public function getJobs()
{
$position_options = DB::table('jposition')->lists('friendly','id');
$category_options = DB::table('jcategory')->lists('friendly','id');
$location_options = DB::table('jlocation')->lists('friendly','id');
return View::make('jobsearch.search', array('position_options' => $position_options, 'category_options' => $category_options, 'location_options' => $location_options))->withInput();
}

Answer 1

withInput() doesn't work the way you think it does. It's only a function of Redirect, not View.
Calling withInput($data) on View has a completely different effect; it passes the following key value pair to your view: 'input' => $data (you get an error because you're not passing any data to the function)
To get the effect that you want, call Input::flash() before making your view, instead of calling withInput(). This should allow you to use the Input::old() function in your view to access the data.
Alternatively, you could simply pass Input::all() to your view, and use the input[] array in your view:
View::make(...)->withInput(Input::all());
which is translated to
View::make(...)->with('input', Input::all());
As for your comment, I recommend doing it like so:
$position_options = DB::table('jposition')->lists('friendly','id');
$category_options = DB::table('jcategory')->lists('friendly','id');
$location_options = DB::table('jlocation')->lists('friendly','id');
$category = Input::get('category');
$location = Input::get('location');
$type = Input:: get('type');
$data = compact('position_options', 'category_options', 'location_options', 'category', 'type', 'location');
return View::make('jobsearch.search', $data);
