public function store(Request $request) { $article = Article::create($request->only(['content'])); $categories = explode(",",$request->get('categories')); $category_ids =[]; foreach ($categories as $category) { $category_db = Category::where('name', trim($category))->firstOrCreate(['name'=> trim($category)]); $category_ids [] = $category_db->id; } $article->category()->attach($category_ids); return response("Successfully Added to Database"); }
In the end there is no comma and no issue and in the database everything is fine
Now problem is that when i put a comma in the end there is a cell created in the database with whitespace
I know why this happening. The last key of the exploded array containing value is whitespace. But i want to omit or leave that empty key. How can i do that?

You should use array_filter()
which will remove all empty keys from the array. So here is the code you should use:
$categories = array_filter(explode(",",$request->get('categories')));
