所以我遇到了问题,如果我点击足够快的subnmit按钮,我的表单会被提交几次。我怎么能阻止这个?令牌是自动添加的,但它根本没有帮助。 表格示例:

  <div class="row padding-10">
    {!! Form::open(array('class' => 'form-horizontal margin-top-10')) !!}
    <div class="form-group">
      {!! Form::label('title', 'Title', ['class' => 'col-md-1 control-label padding-right-10']) !!}
      <div class="col-md-offset-0 col-md-11">
      {!! Form::text('title', null, ['class' => 'form-control']) !!}
      </div>
    </div>
    <div class="form-group">
      {!! Form::label('body', 'Body', ['class' => 'col-md-1 control-label padding-right-10']) !!}
      <div class="col-md-offset-0 col-md-11">
      {!! Form::textarea('body', null, ['class' => 'form-control']) !!}
      </div>
    </div>
    <div class="col-md-offset-5 col-md-3">
      {!! Form::submit('Submit News', ['class' => 'btn btn-primary form-control']) !!}
    </div>
    {!! Form::close() !!}
  </div>

我的NewsController商店方法:

    public function store()
{
$validator = Validator::make($data = Input::all(), array(
  'title' => 'required|min:8',
  'body' => 'required|min:8',
));

if ($validator->fails())
{
  return Redirect::back()->withErrors($validator)->withInput();
}

News::create($data);

return Redirect::to('/news');
}

一种方法是使用按钮的单击处理程序,首先禁用该按钮,然后提交表单。

<script>
    function submitForm(btn) {
        // disable the button
        btn.disabled = true;
        // submit the form    
        btn.form.submit();
    }
</script>

<input id="submitButton" type="button" value="Submit" onclick="submitForm(this);" />

使用PHP sessions将会话变量(例如$_SESSION['posttimer'])设置为发布时的当前时间戳。在PHP中实际处理表单之前,请检查$_SESSION['posttimer']变量是否存在并检查某个时间戳差异(IE:2秒)。这样,您就可以轻松过滤掉多个提交。

// form.html
<form action="foo.php" method="post">
    <input type="text" name="bar" />
    <input type="submit" value="Save">
</form>


// foo.php
if (isset($_POST) && !empty($_POST)) 
{
    if (isset($_SESSION['posttimer']))
    {
        if ( (time() - $_SESSION['posttimer']) <= 2)
        {
            // less then 2 seconds since last post
        }
        else
        {
            // more than 2 seconds since last post
        }
    }
    $_SESSION['posttimer'] = time();
}

是否也要提交按钮的值并防止重复提交表单?

如果您使用的是类型为“提交”的按钮,并且还希望提交按钮的值(如果禁用了该按钮,则不会发生),则可以设置表单数据属性,然后进行测试。

// Add class disableonsubmit to your form
    $(document).ready(function () {
        $('form.disableonsubmit').submit(function(e) {
            if ($(this).data('submitted') === true) {
                // Form is already submitted
                console.log('Form is already submitted, waiting response.');
                // Stop form from submitting again
                e.preventDefault();
            } else {
                // Set the data-submitted attribute to true for record
                $(this).data('submitted', true);
            }
        });
    });
