properly handle error message in laravel controller

Question

I currently have a try/catch around a line of code but when it errors out It's not properly printing out the error. Currently:

try
{
    // code here
}
catch (\Exception $e)
{
    return Redirect::back()
              ->withErrors($e->getResponse()->getBody()->getContents()["message"]);
}

prints:

{

Now if I use:

return Redirect::back()->withErrors($e->getResponse()->getBody()->getContents());

then I get:

{ "message":user doesn't exist }

How can I change this to, upon error, only print "user doesn't exist"?

What is var_dump($e->getResponse()->getBody()->getContents()); giving you? — Blackbam

That's a json string. To get the message, you need to decode the string using json_decode() — M. Eriksson

You need to decode the json string so you can access the message attribute.

try {
    //code here
} catch (\Exception $e) {
    $response = json_decode($e->getResponse()->getBody()->getContents());
    $message = $response->message;

    return Redirect::back()->withErrors($message);
}

You are trying to access a serialized JSON string with array access. This will obviously fail. Here a 1:1 solution which includes the JSON decoding.

try
{
    // code here
}
catch (\Exception $e)
{
    return (json_decode(Redirect::back()
              ->withErrors($e->getResponse()->getBody()->getContents()))->message;
}
