这是我的代码：

$array_theme_options = array(
    array(
        \'id\' => \'facebook_url\',
        \'title\' => \'Facebook Profile Url\',
        \'callback\' => \'display_facebook_element\',
        \'page\' => \'theme-options\',
        \'type\' => \'text\'
    )
);


function input_type($id, $type)
{
    switch ($type) {
        case \'text\':
            $input = \'<input type="text" name="\' . $id . \'" id="facebook_url" value="\' . get_option($id) . \'" />\';
        break;
        case \'checkbox\':
            $input = \'<input type="checkbox" name="\' . $id . \'" value="1" \'.checked(1, get_option($id), true). \' />\';
        break;
    }
    return $input;
}



function display_theme_panel_fields()
{
    global $array_theme_options;
    add_settings_section("section", "All Settings", null, "theme-options");

    foreach ($array_theme_options as $ato) {
        $cf = create_function(\'$id, $type\',\'return input_type($id, $type);\');
        $input_type = $cf($ato[\'id\'], $ato[\'type\']);

        add_settings_field($ato[\'id\'], $ato[\'title\'], $input_type, $ato[\'page\'], "section");
        register_setting("section", $ato[\'id\']);
    }
}
add_action("admin_init", "display_theme_panel_fields");
