return view('import');
}
public function importWord(Request $request)
{
$file_path = $request->file('word_file')->getRealPath();
try {
$word = new COM("Word.Application") or die("Unable to instantiate Word");
$word->Visible = 0;
$word->Documents->Open($file_path);
$content = $word->ActiveDocument->Content->Text;
$word->Quit();
$word = null;
unset($word);
} catch (Exception $e) {
return redirect()->back()->with('error', 'An error occurred while importing the Word document');
}
