Send html code to the database

Hello, I am trying to send this code to the database. I am using a textarea for this.

<iframe src="https://www.google.com/maps/embed?pb=!1m14!1m8!1m3!1d12120.585326380824!2d22.9467158!3d40.5825253!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x14a83f3fcf9f38d1%3A0xfa15735035ac2c0e!2zzpTOl86czp_OoyDOms6RzpvOkc6czpHOoc6ZzpHOoywgzqDOv8-DzrXOuc60z47Ovc6_z4IgNDksIM6gz4XOu86xzq_OsS3Op86_z4HPhM65zqzPhM63z4IgNTU1IDM1!5e0!3m2!1sel!2sgr!4v1654252946213!5m2!1sel!2sgr" width="600" height="450" style="border:0;" allowfullscreen="" loading="lazy" referrerpolicy="no-referrer-when-downgrade"></iframe>

The issue is that it won’t be sent. I get an error (access forbidden), but when I send plain text the insert works.

Any ideas on how to make it work? Thank you!
