Putting Source into DB via php

Hi All

This is a bit of a dumb question i know but hey here goes.

I'm thinking of using fckeditor to allow a client to format the content. Question how do i actually get the source of the textarea to be put into the db.

$_POST only returns the actual text and not the source so for example if the source is

<b>hi there</b>

the $_POST array only contains "hi there" and not the html source

Anyone want to show me the error of my ways and point me in the right direction?

TIA

GM
