wordpress主题复选框

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 =)

It should be

 <p>
        <?php $shortname="whateveryouhadchosen"; ?>
        <?php if( get_option($shortname.'_onoffslider') != '') { ?>
        <?php echo get_option($shortname.'_onoffslider'); ?>

        <?php } else { ?>

        It is ON!

        <?php } ?>
    </p>
