html/template: How to bind nested structs from form data?

从示例中的 c.Bind 调用开始，检查 repository 如何处理请求表单解析和嵌套值。将该行为与标准库的表单数据约定进行比较，然后确定是否支持预期的命名约定，以及最终结果需要文档说明还是范围明确的功能提案。

I'm trying to bind form data to nested structs, but I'm not sure if I'm doing it correctly. Is there a recommended way to handle form binding with nested structs using the standard library?

My Use Case
I have a form structure with nested fields that I want to bind to corresponding nested structs:

type UserInfo struct {
    Name string   `form:"name"`
    Sex string   `form:"sex"`
}

type UserGroup struct {
    Men []UserInfo `form:"men"`
    Women   []UserInfo `form:"women"`
}

type UserResults struct {
    Win          UserGroup `form:"win"`
    Lose UserGroup `form:"lose"`
}

func handler(w http.ResponseWriter, r *http.Request) {
    form := &UserResults{}
    if err := c.Bind(form); err != nil {
	// error handle
    }
    // Values are not bound to nested structs
}

What I've Tried
I've attempted to use dot notation in the form field names:

<form method="POST">
    <input type="number" name="win.men[0].name" value="john">
    <input type="number" name="win.men[0].sex" value="1">
</form>

Questions

1. Is there a built-in way to handle nested struct binding with the standard library?
2. If yes, what is the correct naming convention for form fields?
3. Is there any documentation I might have missed about this topic?

Environment

• Go version: 1.22

Any guidance or best practices would be greatly appreciated. If this functionality isn't currently supported, would it be worth considering as a feature request?
