Catch FatalErrorException PHP - php

Question

Hi everyone! In my Laravel application I have a upload function for an Excel file. I got this code from the web and adjusted it to my application. The problem is, it doesn't catch a fatal error exception which is produced when the user submits a file, but hasn't selected a file. I don't understand why it is not being caught. I will add a part of my controller.
public function upload() {
$file = array('thefile' => Input::file('thefile'));
$rules = array('excel' => 'excel');
$validator = Validator::make($file, $rules);
if ($validator->fails()) {
return Redirect::to('UploadExcelFile')->withInput()->withErrors($validator);
}
else {
try{
// FatalErrorException happens in this line!
if (Input::file('thefile')->isValid()) {
$destinationPath = 'uploads';
$fileName = Input::file('thefile')->getClientOriginalName();
Input::file('thefile')->move($destinationPath, $fileName);
Session::flash('success', 'Upload successfully');
$fileNameJSON = exec("python /path/to/script/ExcelToJSON3.py $fileName"); // This returns a full path name of the JSON file that is made...
if ($fileNameJSON == null){
return Redirect::to('/dashboard/input');
}
else {
// Getting the ID from the file that is uploaded
try {
$jsonDecode = json_decode(file_get_contents($fileNameJSON));
} catch (ErrorException $e){
return Redirect::to('/errorpage')->with(array('status'=> 'ErrorException'));
}
A lot of code for handling the data entered....
}catch (FatalErrorException $e){
return Redirect::to('/errorpage')->with(array('status'=> 'FatalErrorException'));
}
}
return true;
}
The error that is given:
FatalErrorException in UploadExcelFileController.php line 35:
Call to a member function isValid() on a non-object
So, I don't understand why this code doesn't handle the error exception and how I could fix this!

Unless you've imported the namespace that FatalErrorException is declared in with "use" you will need to scope the exception, like this:
catch (\Symfony\Component\Debug\Exception\FatalErrorException $e) {
Otherwise you're using whatever namespace your class is in and trying to catch an exception that is declared in that namespace. It looks like your ErrorException is similarly set up.
I'm not sure that the namespace above is the one your class is deriving from, I'm just guessing it is because you're using Laravel.
