Handling File Upload Exception - Laravel - php

Question

This is how i upload a file into my database but i am not able to handle my exception when the file uploaded is an invalid format or type.
I am able to handle exception when no file is uploaded but not when the file type is invalid or does not meet the standard.
How do i get this done please?
Controller
public function import($id, Request $request)
{
$country= Country::all()->where('id',$id)->first();
if($request->file('imported-file'))
{
$path = $request->file('imported-file')->getRealPath();
$data = Excel::load($path, function($reader)
{
})->get();
if(!empty($data) && $data->count())
{
foreach ($data->toArray() as $row)
{
if(!empty($row))
{
$dataArray[] =
[
'name' => $row['name'],
];
}
else {
return redirect('admin')->with('error','File format Error');
}
}
if(!empty($dataArray))
{
$country->teams()->createMany($dataArray);
return redirect('admin')->with('status','Countries successfully added');
}
}
}
else {
return redirect('admin')->with('error','No file was uploaded');
}
}

Answer 1

From Laravel's documentation, You can accept only a certain type of file using mime validation rule,
'file' => 'required | mimes:application/vnd.ms-excel',
The mime-type application/vnd.ms-excel will match these file extensions xls xlm xla xlc xlt xlw

I have uploading excel files in one of my project. Hope this will helps you:-
$file = Input::file('imported-file');
Excel::load($file ,function($reader){
$reader->each(function($sheet){
YourMOdelName::firstOrCreate($sheet->toArray());
});
});
YourModelName is your table name suppose if table is users so you have to define User in that case.....
From this way you can get the extenstion of your uploading file:-
$ext= Input::file('imported-file')->getClientOriginalExtension();
echo $ext; //print the extension here
Hope it willl help!

Okay i solved this in a very simple way by checking out the laravel documentation. So here is what i just added
if(($request->file('imported-file')->getClientOriginalExtension() != 'xls, xlm, xla ,xlc, xlt, xlw'))
{
}
else {
//process the file
}
