ASP.NET MVC 如何实现多个表单验证和提交

[Dick_Xie]

比如说有这么一个页面，包含了用户注册和登录，需要分别验证输入和提交，使用ASP.NET MVC应如何实现？

[Dick_Xie]

是不是问题太傻了呢？

[nwxhl]

不是很了解mvc 虽然是2.0了。

大概知道是 post 到 model 类里面直接接受数据验证就可以了。至于你要做什么操作，我想都应该可以的。
不明白你为何要提交多个表单

注册完，直接都登陆了。mvc 默认生成该程序。

Asp.net MVC中表单验证

[wanghuaide]

分别放在二个from里，form 的action="***.aspx"

[Dick_Xie]

代码贴上，请帮忙提点建议，主要是如何分别处理表单验证，两个form会有同名的表单项:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Register And LogOn
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Register And LogOn</h2>

<div style="float: left; width: 400px;">
<% using (Html.BeginForm("Register2", "Account", FormMethod.Post, new { id = "registerForm" }))
{ %>
<%= Html.ValidationSummary(true, "Account creation was unsuccessful. Please correct the errors and try again.", new { id = "RegisterValidationSummary" })%>
<div>
<fieldset>
<legend>Account Information</legend>

<div class="editor-label">
<%= Html.Label("UserName") %>
</div>
<div class="editor-field">
<%= Html.TextBox("UserName") %>
<%= Html.ValidationMessage("UserName", "*") %>
</div>

<div class="editor-label">
<%= Html.Label("Email") %>
</div>
<div class="editor-field">
<%= Html.TextBox("Email") %>
<%= Html.ValidationMessage("Email", "*") %>
</div>

<div class="editor-label">
<%= Html.Label("Password") %>
</div>
<div class="editor-field">
<%= Html.Password("Password") %>
<%= Html.ValidationMessage("Password", "*") %>
</div>

<div class="editor-label">
<%= Html.Label("ConfirmPassword") %>
</div>
<div class="editor-field">
<%= Html.Password("ConfirmPassword") %>
<%= Html.ValidationMessage("ConfirmPassword", "*") %>
</div>

<p>
<input id="register" type="submit" value="Register" />
</p>
</fieldset>
</div>
<% } %>
</div>
<div style="float: right; width: 280px">
<% using (Html.BeginForm("LogOn2", "Account", FormMethod.Post, new { id = "logonForm" }))
{ %>
<%= Html.ValidationSummary(true, "Login was unsuccessful. Please correct the errors and try again.", new { id = "LogonValidationSummary" })%>
<div>
<fieldset>
<legend>Log On</legend>

<div class="editor-label">
User Name
</div>
<div class="editor-field">
<%= Html.TextBox("UserName") %>
<%= Html.ValidationMessage("UserName", "*")%>
</div>

<div class="editor-label">
Password
</div>
<div class="editor-field">
<%= Html.Password("Password")%>
<%= Html.ValidationMessage("Password", "*")%>
</div>

<div class="editor-label">
<%= Html.CheckBox("RememberMe") %>
<%= Html.Label("RememberMe") %>
</div>

<p>
<input id="logon" type="submit" value="Log On" />
</p>
</fieldset>
</div>
<% } %>
</div>
<div style="clear: both"></div>

</asp:Content>

Controll:
public ActionResult RegisterAndLogOn()
{
return View();
}

[HttpPost]
public ActionResult LogOn2(string userName, string password, bool rememberMe, string returnUrl)
{
if (ModelState.IsValid)
{
if (ValidateLogOn(userName, password))
{
if (MembershipService.ValidateUser(userName, password))
{
FormsService.SignIn(userName, rememberMe);
if (!String.IsNullOrEmpty(returnUrl))
{
return Redirect(returnUrl);
}
else
{
return RedirectToAction("Index", "Home");
}
}
else
{
ModelState.AddModelError("logonForm", "The user name or password provided is incorrect.");
}
}
}

// If we got this far, something failed, redisplay form
return View("RegisterAndLogOn");
}

[HttpPost]
public ActionResult Register2(string userName, string email, string password, string confirmPassword)
{
if (ModelState.IsValid)
{
if (ValidateRegistration(userName, email, password, confirmPassword))
{

// Attempt to register the user
int createStatus = MembershipService.CreateUser(userName, password, email);

if (createStatus > 9999)
{
FormsService.SignIn(userName, false /* createPersistentCookie */);
return RedirectToAction("Index", "Home");
}
else
{
ModelState.AddModelError("registerForm", AccountValidation.ErrorCodeToString(createStatus));
}
}
}

// If we got this far, something failed, redisplay form
ViewData["PasswordLength"] = MembershipService.MinPasswordLength;
return View("RegisterAndLogOn");
}

这个问题不是很难吧，一个网面只能有一个from ,但每个控件都一个ValidationGroup属性，属于一组的控件或验证控件和提交按钮，把他们的ValidationGroup值设相同的名字，这样多个提交，都互不干涉了。

[Dick_Xie]

怎么去处理多个“Html.ValidationSummary”呢？

[手抓宝]

不建议放在一个页面中

[sjt000]

每次操作只有一个啊～

[Dick_Xie]

但如果确实有这样的需求，如何处理，提提建议，谢谢。

[Dream_Hunter_]

mvc有自带的验证控件
另外也可以在form的action指向的action里做判断，再显示页面

[lyvscf]

多个表单对应多个form

[Im_Sorry]

up!~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[cphackers]

如果确实需要，可以用AJax做

[challenger_chen]

建议分开来做
