Laravel - Form Action to Controller Function - php

Question

I'm trying to create a situation where a user can load a page, select a timesheet number, and then have the system delete all records associated with that timesheet number. This function loads the form page:
public function deletetimesheetLoad()
{
$timesheets = collect(DB::select("SELECT dbo.TIME.Source AS Source
FROM dbo.TIME
GROUP BY dbo.TIME.Source
ORDER BY dbo.TIME.Source ASC"));
return view('utilities/deletetimesheet',['timesheets' => $timesheets]);
}
This is the actual blade template:
<form method="post"
action="{{url('/time/deletetimesheet/process')}}"
enctype="multipart/form-data"
<div class="form-group">
<label class="col-md-12 control-label" for="TIMESHEETNUMBER">Timesheet Number</label>
<div class="col-md-12">
<select required id="TIMESHEETNUMBER" name="TIMESHEETNUMBER" class="form-control select2_field">
<option value=""></option>
#foreach ($timesheets as $row)
<option value="{{ $row->Source }}">{{ $row->Source }}</option>
#endforeach
</select>
</div>
</div>
<div id="saveActions" class="form-group">
<input type="hidden" name="save_action" value="Submit">
<div class="btn-group">
<button type="submit" class="btn btn-success">
<span class="fa fa-save"></span>
<span data-value="Submit">Submit</span>
</button>
</div>
<span class="fa fa-ban"></span> Cancel
</div>
This is the function that the form action is pointing to:
public function deletetimesheetProcess(TimesheetRequest $request)
{
DB::table('TIME')->where('Source', $request->get('TIMESHEETNUMBER'))->delete();
\Alert::success(trans('yay'))->flash();
return view('details/customershow',[]);
}
Here are the defined routes for the two functions:
Route::get('/time/deletetimesheet', 'Admin\TimeCrudController#deletetimesheetLoad');
Route::post('/time/deletetimesheet/process', 'Admin\TimeCrudController#deletetimesheetProcess');
Currently the blade template loads correctly, and does not throw an error on submit - just reloads the current page. What am I doing wrong?
