checkbox in theme options page [closed]

Question

This is the code I have to display the checkbox in the theme options page:

$options[] = array( "name" => "Enable/Disable Slider",
                "desc" => "If you don´t want to see the slider on your homepage you can disable it here.",
                "id" => $shortname."_onoffslider",
                "std" => "",
                "type" => "checkbox",
                "class" => "");

The checkbox now is there. And also I have this bit of code to echo the value true or false in my template. like this:

            <p>
            <?php if( get_option('_onoffslider') != '') { ?>
            <?php echo get_option('_onoffslider'); ?>

            <?php } else { ?>

            It is ON!

            <?php } ?>
        </p>    

In the template page the text "It is ON!" always shows, no matter the checkbox is on or off. I know the code is wrong but i can´t fix it.

Any help? thanks =)

If I'm correct when you use the checkbox on options it saves a value when it is checked but when it's not it doesn't save one so basically it has a null value and it is going to be always != ''. Try dumping the retrieved value ( var_dump(get_option()) ) then you'll be sure what does it return
