Question

我正在尝试为wordpress创建一个微笑插件。我需要能够更新自定义选项的get_option（）变量。如果您知道下面的脚本有什么问题，请告诉我。

它会将字段添加到数据库并显示设置页面，但是当我点击“保存更改”按钮时它不会更新它们。

请让我知道我做错了什么......

我无法更改插件的选项页面中的任何选项值...

Answer 1

尝试使用update_option()更新选项。

add_option()添加了该选项，但它不会更新它，而update_option()也会创建它，如果它不存在的话。

希望这有帮助。

在PHP中为插件创建选项页面：get_option（）
