Laravel saving post variable when there is validation error? - php

Question

I am using laravel 4 , and I have a form with checkboxes and on sumbitting the form , it goes through the validation error process, if there is error how do I make it save the post values of these check boxes?
AdminRolesController:
public function postActions($action = NULL) {
// Allowed post actions..
$allowed = array('add', 'edit');
$action = in_array($action, $allowed) ? $action : NULL;
// check if action is not null
if(is_null($action))
return Redirect::to('admin/roles');
else
{
// POST ACTION
if($action == "add")
{
// put all your rules.
$rules = array(
'name'=>'required|regex:/^[a-zA-Z ]*$/|min:2',
'permission_ids' =>'required'
);
// run the validation rules on the inputs from the form
$validator = Validator::make(Input::all(), $rules);
// get all permissions or groups available
$perms = Permissions::all();
// share it to the view
// we have two parts of permissions ( 0 , 1)
// 0 : Admin Group Pages , 1: Front End Pages
View::share('perms', $perms);
if ($validator->passes())
{
// validation has passed, save user in DB
// create instance of our model..
// create a new role
$role = new Role;
$role->name = Input::get('name');
$permission_ids = Input::get('permission_ids');
// save info to db.
$role->save();
$msg = 'Role '.$role->name.' has been added';
}// end validation if
else
{
// validation has failed, display error messages
return Redirect::back()->with('message', 'The following errors occurred:')->withErrors($validator)->withInput();
}
}// end if add
}
}
I think part of the problem me redirecting with error messages , all the post values is lost , how could I still keep them?
Thanks

Your controller looks fine - all that's required to do to pass input back to the view is chaining ->withInput()
However, in your views, ensure you're populating the form using the old input values. You can do so, using Blade, by doing something like:
{{ Form::checkbox('permission_id', 'value', Input::old('permission_id)) }}
