Question

我想只获取已触发的消息，但我收到了所有已注册的消息。

var ticket_arr = '[{"Id":"a874062a-3f1e-4f91-a9d7-334aedd2e79f","Name":"Tesr","StartDate":"2015-04-08","EndDate":"2015-04-09","Duration":"1","leaf":true,"IsProject":false,"IsStage":false,"IsActivity":false,"IsTicket":true,"IsTask":false},{"Id":"19f3722f-5f19-430a-bf8a-699c6841aec2","Name":"Go define this test projecct","StartDate":"2015-04-21","EndDate":"2015-04-29","Duration":"8","leaf":true,"IsProject":false,"IsStage":false,"IsActivity":false,"IsTicket":true,"IsTask":false},{"Id":"5576edbf-3feb-4204-b488-0d0a35688538","Name":"Mike is getting a lesson in cool","StartDate":"2015-04-08","EndDate":"2015-04-10","Duration":"2","leaf":true,"IsProject":false,"IsStage":false,"IsActivity":false,"IsTicket":true,"IsTask":false},{"Id":"5bf5d77c-73b1-480b-8758-2e822db73964","Name":"Test ticket","StartDate":"2015-04-08","EndDate":"2015-04-09","Duration":"1","leaf":true,"IsProject":false,"IsStage":false,"IsActivity":false,"IsTicket":true,"IsTask":false}]';

function sortArray(arr, name){
    arr.sort(function(a,b) 
        {
      if (new Date(a[name]) > new Date(b[name]) )
         return 1;
      else if (new Date(a[name]) < new Date(b[name]) )
         return -1;
       else
         return 0;
    }); 
}
function getMinMaxDate(arr, name, type)
{
    if(arr.length)
    {
        sortArray(arr, name);
        console.log(arr);
        console.log(name);
        if(type == "Min" && arr.length)
        {
                        console.log(arr[0][name]);
            return arr[0][name];
        }

        if(type == "Max" && arr.length)
        {
            return arr[arr.length-1][name];
        }
    }
    else
        return '';
}

稍后在控制器中：

$inputFilter = $factory->createInput(array(
        'name'       => 'image',
        'required'   => true,
        'validators' => array(
            array(
                'name'    => '\Zend\Validator\File\IsImage',
                'options' => ['message' => 'File has to be valid image.']
            ),
            array(
                'name'    => '\Zend\Validator\File\Extension',
                'options' => ['extension' => 'png,jpg,jpeg', 'message' => 'Image extension has to be png,jpg or jpeg.'],
            ),
            array(
                'name'    => '\Zend\Validator\File\Size',
                'options' => ['max' => '2MB', 'message' => 'Maximum file size for image is 2MB.'],
            ),
        ),
    ));

如果我尝试上传5MB大小的图片，我会收到所有消息：

if(!$filter->isValid()){
    var_dump($filter->getMessages());
}

但仅预期＆＃34;图像的最大文件大小为2MB＆＃34;。

有没有办法只返回触发的消息？这应该是getMessages（）方法的默认行为吗？

可能的解决方案是使用Validator Chains。

在某些情况下，如果验证程序的验证过程失败，那么验证器就会破坏链条。 Zend\Validator\ValidatorChain支持使用attach()方法的第二个参数的此类用例。通过将$breakChainOnFailure设置为TRUE，添加的验证器将在发生故障时中断链执行，从而避免运行任何其他确定为不必要或不适合该情况的验证。

这样，验证在第一次失败时停止，您将只有验证失败的消息。您还可以设置优先级，以便按特定顺序应用验证器。文档中给出的这个示例使用方法attach。这不是你所需要的。

在您的情况下，您可以在验证程序规范中使用break_chain_on_failure键，并将值设置为true。像这样：

$inputFilter = $factory->createInput(array(
        'name'       => 'image',
        'required'   => true,
        'validators' => array(
            array(
                'name'    => '\Zend\Validator\File\IsImage',
                'options' => ['message' => 'File has to be valid image.']
                'break_chain_on_failure' => true,
            ),
        ),
));

ZF2文件验证器返回所有消息，但只需触发
