如何使用php表单的重置按钮？

I've got a form that I'm handling with PHP. Before the user submits it, the Reset button works. But when they submit and the page reloads (I've made the form fields sticky based on the $_POST values) the reset doesn't work. How can I fix that? EDIT: For example, a checkbox on the form:I've got a form that I'm handling with PHP. Bef
