Laravel过滤所有列中的值

Question

public function getBooks($input)
{
    $books= Book::where('book_name', 'LIKE', '%' . $input . '%')->get();
    return Response::json($books);
}

I know how to filter a column by a given value. But how do I filter ALL columns by a given value. For example, I have a column called 'category' where user should be able to use the same search bar to filter the category.

Something like:

$books = Book::where('all_columns', 'LIKE', '%' . $input . '%')->get();

Thanks!

Most databases do not support searching all columns simultaneously. I'm afraid you'll likely have to chain all of the columns together:

$books = Book::where('book_name', 'LIKE', '%' . $input . '%')
    ->orWhere('another_column', 'LIKE', '%' . $input . '%')
    // etc
    ->get();
