jquery textarea resizer not in POST?

I'm using TextArea Resizer to allow the sizing of a textarea (similar to stackoverflow) found at http://plugins.jquery.com/project/TextAreaResizer.

It works for the end user. However, when I submit the form, the textarea is no where to be found within the POST array. Why is that? As soon as I change the class name and submit the form, the POST value开发者_StackOverflow社区 is there. Weird. Any ideas?

<textarea class="resizable" name="ingredients"></textarea>

Perhaps it is being renamed? Do a var_dump($_POST); and see what you are actually posting.
