只需设置name 复选框标记中的属性，格式如下：favourite_colors[]. 以下代码派生自this thread.

add_settings_field(  
    \'favourite-colors\',  
    \'Select your favourite colour\',  
    \'favourite_colors_checkbox_callback\',  
    \'my-settings\'
);

function favourite_colors_checkbox_callback() {

    $options = get_option( \'favourite_colors\' );

    $html = \'<input type="checkbox" id="red" name="favourite_colors[red]" value="1"\' . checked( 1, $options[\'red\'], false ) . \'/>\';
    $html .= \'<label for="red">Red</label><br />\';
    $html = \'<input type="checkbox" id="yellow" name="favourite_colors[yellow]" value="1"\' . checked( 1, $options[\'yellow\'], false ) . \'/>\';
    $html .= \'<label for="yellow">Yellow</label>\';

    echo $html;

}
