There are three WordPress functions worth mentioning when working with forms. checked, selected and disabled provide a quick way of setting a checked boxed to checked, an option of a select tag to selected or disabling a field varying the value of the input.
The three functions, fully listed below, compare $checked, $selected or $disabled against $current (which defaults to true) and provides the option to echo the result if $echo is true, or return the result if $echo is false.
checked( $checked, $current = true, $echo = true ); selected( $selected, $current = true, $echo = true ); disabled( $disabled, $current = true, $echo = true );
