首先：我真的是个新手。因此，我为我的选项页面使用了一个模板，并尝试对其进行自定义（到目前为止效果很好）。

关于我的插件：它创建发布类型和其中的一些元框。元框有一些字段，到目前为止保存字段的效果相当不错。

现在我要说的是，我希望我的选项不仅显示在选项页面上，而且保存输入的值。

我用“简短摘录”试试，因为所有其他选项都是一样的。

我不知道复选框是否需要清理或验证…我不知道如何保存当前值，当然也不知道如何在默认情况下加载。我找到了使用php函数而不是value=“xxx”的示例，但不知道如何将其包括在内，是的……我知道……当需要显示当前值时，checked属性不应该存在：）也许有人可以帮我
