我试过使用sanitize_text_field() 和esc_attr() 在将复选框数据的值保存到数据库时筛选复选框数据，但这会导致数据无法保存。
是什么原因造成的以及过滤输入的正确方法是什么checkbox 和radio?
清理发送到数据库的复选框值的正确方法是什么

我将使用filter\\u var（）函数。它有一些预定义的过滤器，您可以根据所需的数据类型（如字符串、数字等）使用这些过滤器。
因此，要进行一些消毒：
$sanitizedNum = filter_var($yourVar, FILTER_SANITIZE_NUMBER_INT);
然后将它们包装到自定义函数中。

我的意思是checkbox或radio的值通常是一个整数值。如果是整数值，则将其设置为整数作为实心过滤器。
$checkbox = (int) $checkbox;
esc_attr 过滤固体。功能sanitize_text_field 还有一个过滤器，其他插件可以更改输出，可能对您的目标没有帮助。该函数更多用于过滤来自用户或数据库的输入。esc_attr还有一个过滤器，但更符合您的要求。有关更多信息，请访问codex page about validation.
