How to set checkbox values for checked or not checked

I have  a checkbox with a value of "yes" if it is checked. It inserts fine into the database if I actually check the checkbox. If I don't, then I get a php error.

Can you use html to have a value for checked and not checked or would I have to use php and do something like, if it isn't empty then it = yes or if it is empty then it = no.

before I write the php, I was just wondering if there was a simpler way just using html?

<input type="checkbox" data-toggle="checkbox" name="featured" value="yes"> Featured product </label>

in php, you can try this:

$featured= (isset($_POST['featured']))?"Yes":"No";

You can use a hidden input in HTML to set a default value for a checkbox.

Full explanation and code examples here:

See especially Another Take on Unchecked Checkboxes.  This works in PHP because of the way that raw post data is presented to the PHP script in the $_POST associative array.  If you were dealing with raw post data in another language, you would need to do what PHP already does for us -- put the post data elements into the $_POST array, using the key/value pairs and overwriting the values for repeated identical keys.

I really like the simple way of using a hidden field. That worked like a charm :)
