micah1701 Posted May 10, 2006 Share Posted May 10, 2006 I'm not sure I follow your problem?a "checkbox" is an HTML element, not PHP.a checkbox can be checked, or unchecked. if it is checked, when the form is submitted, the "value" is passed in $_POST with the element's "name". Your above code looks fine.a "checkbox" however, can not be a "BUTTON"unless you add a some sort of "onClick" javaScript to the checkbox, it can not behave like a button.If this doesn't help, perhaps you could explain your problem w/ more detail.Thanks!

ober Posted May 10, 2006 Share Posted May 10, 2006 You missed Micah's point. Nowhere in what you've posted does it show a submit button in the form. You MUST have a submit button or an "onclick" event in the checkbox that calls a javascript submit event.
