can i see the view's code?

I'm not sure how to post it so it's helpful. There is a lot going on in the view.

I'm not able to return anything from the controller method actually anymore...unless I use dump & die. Why would that be?

example (doesn't work):

public function postApplication($type){
        if ( $validation->passes() ) {
            //do something here
	} else {
	    Redirect::to(URL::previous());
	}
}

example (works):

public function postApplication($type){
        if ( $validation->passes() ) {
            //do something here
	} else {
	    dd(URL::previous());
	}
}

you need to return the Redirect::to(URL::previous());

    if ( $validation->passes() ) {
        //do something here
} else {
    return Redirect::to(URL::previous());
}

No luck there either. It just loads a blank page and never redirects anywhere.

I've tried: return Redirect::to(URL::previous()); return Redirect::back(); return Redirect::action();

what url did you get? the previous url?

can you try return URL::previous();

I get the previous url, but nothing is rendered on the page.

Nothing happened with return URL::previous(); either....so bizarre.

if you can paste your views page to see what going on.

You can try this

return Redirect::to(URL::previous())->withInput()->withErrors($validation);

did you try this?

return Redirect::to(URL::previous())->withInput()->withErrors($validation);

remove you views page in this thread.

Yes, I did...didn't affect anything unfortunately.

did you get blank page again? try to view source.

Yeah, view source is empty.

Even if I do:

return View::make('index');

I get nothing.

are you putting something in the first block? it might be there are no errors?

if ( $validation->passes() ) {
        //nothing is in here
        //so you get a blank page
} else {
    return Redirect::to(URL::previous())->withInput()->withErrors($validation);
}

I had the same problem. Turned out I used

Redirect::back()->withErrors($validator)->withInput();

and constantly received white pages instead of being redirected back. Only worked once I explicitly used a return statement

return Redirect::back()->withErrors($validator)->withInput();

May seem like a silly thing to overlook, but if you're having the same problem it's worth ruling out...

@Stekefanten:

return Redirect::back()->withErrors($validator)->withInput();

is problematic when you add setStatusCode(422) to it: result creates separate response page with redirection warning in it and then redirects:

return Redirect::back()->withErrors($validator)->withInput()->setStatusCode(422);

I know this is an old thread, but for anybody who finds this thread still having issues, make sure the Redirect isn't in a closure for another function.

For example:

Excel::load($filename, function ($reader) {
    ... some other code ...
    return Redirect::back()->withErrors($errors);
});
