A textarea isn't like the other inputs because it's a different tag. Instead of a value input, the "value" is just placed between the tags. So modify the code above like this:
<textarea name="name"><?php if (!empty($_POST['name'])) { echo htmlentities($_POST['name']); } ?></textarea>

Note that this method works for most types of input, perhaps with some manipulation (such as for a checkbox).
However, for a select menu (maybe radio buttons as well) it becomes more complicated because you need to use a loop to determine which value was selected.

Very late reply (9 years later), but how can you implement this into a html page? The PHP processor is a seperate .php document.
Thanks!
