How To Select / Get Values From Database In Laravel - php

Question

I am creating a web site and I have a Registration form. So , when someone going to use a username and email which is already in the database , I want to show them a message " Username and Email already taken " like this. If username and email are unique , user can register. But , when I try to register someone , it always shows " Username and Email already taken ". I can't register even when I use unique data.
How can I Fix this ??
AdminPanel.blade.php
#if(session()->has('OnlyImg'))
<h4 class="alert alert-success"> {{ session()->get('OnlyImg') }} </h4>
#endif
<form class="form-horizontal" method="POST" action="{{ route('adinsert') }}" enctype="multipart/form-data">
{{ csrf_field() }}
<div class="form-group">
<label>Username : *</label>
<input type="text" class="form-control" name="username" value="{{ old('username') }}" placeholder="Enter Your Username" required>

</div>
<div class="form-group">
<label>Password : *</label>
<input type="password" class="form-control" name="password" value="{{ old('password') }}" placeholder="Enter Your Password" required>
</div>
<div class="form-group">
<label>Upload Profile Picture :</label>
<input type="file" class="form-control-file" name="file_img" aria-describedby="fileHelp">
<small id="fileHelp" class="form-text text-muted">If U Want , U Can Skip Upload A Profile Picture</small>
</div>
#section('btnName',"Insert")
<input type="submit" class="btn btn-primary" onclick="myFunction()" name="submit" value="#yield('btnName')">
</form>
AdminPanelController.php
public function adinsert(Request $request)
{
$username = $request->input('username');
$email = $request->input('email');
$password = bcrypt($request->input('password'));
//$passen = bcrypt($password);
$user = new User();
$user->username = $username;
$user->email = $email;
$user->password = $password;
$this->validate($request, [
'email' => 'required'
]);
$res = DB::table('users')->where(['username' => $username, 'email' => $email])->get();
if ($res > 0 ) {
$request->session()->flash('Msg', 'Email already taken , Use another Email !!');
return redirect('AdminPanel');
}
else
{
if(Input::hasFile('file_img')){
$file = Input::file('file_img');
$rules = array(
'file_img' => 'required|max:10000|mimes:jpeg,png,jpg'
);
$validator = Validator::make(Input::all(), $rules);
if ($validator->fails()) {
$request->session()->flash('OnlyImg', 'You Can Only Upload Images !!');
return redirect('AdminPanel');
}
else if ($validator->passes()) {
$fileimg = $file->getClientOriginalName();
$destinationPath = 'img/Admins/';
$filemove = $file->move($destinationPath, $fileimg);
$user->fileimg = $fileimg;
$user->filemove = $filemove;
$user->save();
$request->session()->flash('Msg', 'Successfully Inserted !!');
return redirect('AdminPanel');
}
}
else
{
$user->save();
$request->session()->flash('Msg', 'Successfully Inserted !!');
return redirect('AdminPanel');
}
}
}
Here is Route.
Route::post('adinsert',[
'uses'=> 'AdminPanelController#adinsert',
'as' => 'adinsert'
]);
