我正在尝试根据Netuts上的教程向新模板添加自定义选项面板。我将选项面板的所有代码保存在一个名为optionpanel的文件中。php（LoL）和一切都正常，但现在我想添加一个上传/图像按钮，这样我就可以直接从Wordpress媒体库更改幻灯片中的图像，而不是每次都通过FTP连接。
问题是，如何做到这一点？这就是我现在所拥有的，我可以看到媒体上传框，我可以上传图像，图像存储在媒体库中，但当我单击选项面板中的“保存”并尝试回显该功能时，它不会给我任何提示，在保存有图像链接的表单后，该图像再次变为空！
我知道我的英语很难听，请礼貌一点，如果可以的话，试着向我解释，就像你在和你3岁的儿子说话一样！
我搜索了很多（可能太多了！！！）我读到：
