Where am I making a mistake in if else statement? - laravel

Question

I can't return a toast error message. Where am I making a mistake? Message returns when successful.
My code is as follows:
public function store(Request $request)
{
$validated = $request->validate([
'category_name' => 'required|unique:categories|max:50',
]);
$data = array();
$data['category_name'] = $request->category_name;
$save = DB::table('categories')->insert($data);
if ($save) {
Toastr::success('Post Successfully Saved :)', 'Success');
return redirect()->route('admin.category');
} else {
Toastr::error('Error :)', 'Error');
return redirect()->route('admin.category');
}
}

Answer 1

Try the following:
public function store(Request $request)
{
$validated = $request->validate([
'category_name' => 'required|unique:categories|max:50',
]);
$data = array();
$data['category_name'] = $request->category_name;
$save = DB::table('categories')->insert($data);
if (!$save) {
Toastr::error('Error :)', 'Error');
return redirect()->route('admin.category');
} else {
Toastr::success('Post Successfully Saved :)', 'Success');
return redirect()->route('admin.category');
}
}

You can try this code.. You can use ->fails() function to check the inputs
public function store(Request $request)
{
$validated = $request->validate([
'category_name' => 'required|unique:categories|max:50',
]);
if($validated->fails()){
Toastr::error('Error :)','Error');
return redirect()->route('admin.category');
}
$data=$request->only(['category_name']);
$save = DB::table('categories')->insert($data);
Toastr::success('Post Successfully Saved :)','Success');
return redirect()->route('admin.category');
}

I found the solution . I created a validator myself
public function store(Request $request)
{
$validated = Validator::make($request->all(), [
'category_name' => 'required|unique:categories|max:50',
]);
$notificationerror=array(
'messege'=>'Category Added Error',
'alert-type'=>'error',
'positionClass' =>'toast-top-right'
);
if($validated->fails()){
return redirect()->route('admin.category')->with($notificationerror);
}
$data=array();
$data['category_name']=$request->category_name;
DB::table('categories')->insert($data);
$notification=array(
'messege'=>'Category Added Successfully',
'alert-type'=>'success',
);
return redirect()->route('admin.category')->with($notification);
}
