I have a form that asks for comments. The form is submitted to a PHP action program that emails off the contents and redisplays the form. But the form is displayed by just including a form.html file, so it's just the generic form that gets generated again. But I'd like to display "Thank you for your comments." in the comment textarea element when I display the form the second time, so I need some way to get a hold of input#comments, which is a textarea in the form, from php, so I can set value to "Thank you for your comments."
Thanks for any suggestions
