我用过this nettuts tutorial 创建选项面板。当我尝试添加当前用户信息时，我正在尝试如何做，但迄今为止没有成功（我不断“破坏”代码/出现服务器错误）。。。我有3个自定义选项，我想提供给客户，而其余的只有管理员可用。我尝试在我的函数文件中添加此代码，但我提到了上面的错误。

if(current_user_can(\'manage_options\')) {
array( "name" => "Site Nav Background Image",
    "type" => "section"),
array( "type" => "open"),   

array( "name" => "Site Nav Background Image",
    "desc" => "Paste URL for site navigation background image",
    "id" => $shortname."_nav_bkg",
    "type" => "text",
    "std" => ""),

array( "type" => "close"),
} else {
array( "name" => "Custom CSS",
    "type" => "section"),
array( "type" => "open"),   

array( "name" => "Custom CSS",
    "desc" => "Want to add any custom CSS code? Put in here, and the rest is taken care of. This overrides any other stylesheets. eg: a.button{color:green}",
    "id" => $shortname."_custom_css",
    "type" => "textarea",
    "std" => ""),       

array( "type" => "close"),

    }
}

有没有一个我错过的简单解决方案？有人能告诉我如何错误地使用上述代码吗？

TIA！
