Problem with Security when inserting HTML/javascript code into MYSQL table fields

[student]

Hello,
We run an affiliate program and affiliates send visitors to our site.
We would like to allow our affiliates to customize their landing pages by allowing them to add any HTML / javascript / text to it.

For example: affiliates may insert their google adsense code etc.

So, we need to insert this data in to the database table:
id
name
email
code

This 'code' will be any HTML / javascript / text.

Later we read from the table and insert that HTML / javascript / text into the landing page.

I doubt if any user may input any malicious script or code.

How to ensure the safety of the database while inserting that code.

Please suggest.
Thank you.

Not sure what you are asking. If you are worried about quotes and what not in the code then run it through mysql_real_escape_string on the data before it goes into the database.
