I am trying to get count of header from an uploaded CSV file. But I am getting error "Call to a member function keys() on null". Here is my code.
public static function import(request $request) { $error = [];
if($request->hasFile('file'))
{
$path = $request->file->getRealPath();
$data = Excel::load($path)->first()->keys()->toArray();
$countHeader = count($data);
echo $countHeader;
return;
if($countHeader <= 10 )
{
echo
$error = "file header are less than 10";
}
else
{
$error = "file headers is okay";
}
} else { $error = "Please select file"; } return $error;
} thanks
Please do post your form code
Ensure that you have enctype
<form action="/url" method="post" enctype="multipart/form-data">
If this is not present, it wont allow file uploads.
Also try to var_dump($path) to see if the $path actually has something
I had a CSV with headers only. that's why it was giving an error. I wrote some data into that CSV file and it works fine.
Please or to participate in this conversation.
