Question

How can I send a radio or checkbox value to the $_POST array even when the field is empty?

\';
            


        

Answer 1

Consider this example:

// Set a default value as male
 Male
 Female

and you will get the value

Array
(
    [name] => 
    [email] => 
    [gender]=>male
)

You only get the checked radio in the $_POST array
