Php 为什么多个场景在Yii中不起作用？

我在应用程序中使用了多个场景，但每次最后一个场景都会覆盖第一个场景时都会遇到问题

控制器： 关于：

首先，需要注意的是，任何未分配给场景的规则都将应用于所有场景

因此，我认为您可能不需要场景，只需要使用通用规则/验证

或

您的规则有一个场景，如下所示：

public function rules()
{
    return array(
      [...]
      array('cost_spares','numerical',
        'integerOnly' => true,
        'min' => 1,
        'max' => 250,
        'tooSmall' => 'You must order at least 1 piece',
        'tooBig' => 'You cannot order more than 250 pieces at once',
        'message' => 'Do not enter zero or/and characters for Spare parts!',
        'on' => 'myScenario'),
      array('cost_labour','numerical',
        'integerOnly' => true,
        'min' => 1,
        'max' => 250,
        'tooSmall' => 'You must order at least 1 piece',
        'tooBig' => 'You cannot order more than 250 pieces at once',
        'message' => 'Do not enter zero or/and characters for Labour Charges!',
        'on' => 'myScenario'),
    );
}

  array('cost_spares', 'cost_spare_func',
    'message' => 'Do not enter zero or/and characters for Spare parts!',
    'on' => 'cost_spare_func'),

  array('cost_spares', 'match',
    'pattern' => '/^[a-zA-Z]+$/',
    'message' => 'Do not enter zero or/and characters for Spare parts!',
    'on' => 'cost_spare_func'),

在控制器中，您只需编写：

public function actionUpdate ($id)
{ 
  if (isset($_POST['TblEnquiry']))
  {
     [...]
     $model->setScenario('myScenario');
  }
}

编辑：
关于，我只看到您只需要

数字

输入。所以这可能更适合你的需要。由于两者都得到了相同的检查，您可以只进行一次检查，然后将消息传递给它。但就目前而言，这应该是可行的

额外的：
你的规则中还有一个bug，就像你写的那样

  array('cost_spares', 'cost_spare_func', 'match',
    'pattern' => '/^[a-zA-Z]+$/',
    'message' => 'Do not enter zero or/and characters for Spare parts!',
    'on' => 'cost_spare_func'),

这是不可能的。不能将规则验证函数和默认验证（如

match

）混合使用

这意味着您只能像这样定义

验证函数

：

public function rules()
{
    return array(
      [...]
      array('cost_spares','numerical',
        'integerOnly' => true,
        'min' => 1,
        'max' => 250,
        'tooSmall' => 'You must order at least 1 piece',
        'tooBig' => 'You cannot order more than 250 pieces at once',
        'message' => 'Do not enter zero or/and characters for Spare parts!',
        'on' => 'myScenario'),
      array('cost_labour','numerical',
        'integerOnly' => true,
        'min' => 1,
        'max' => 250,
        'tooSmall' => 'You must order at least 1 piece',
        'tooBig' => 'You cannot order more than 250 pieces at once',
        'message' => 'Do not enter zero or/and characters for Labour Charges!',
        'on' => 'myScenario'),
    );
}

  array('cost_spares', 'cost_spare_func',
    'message' => 'Do not enter zero or/and characters for Spare parts!',
    'on' => 'cost_spare_func'),

  array('cost_spares', 'match',
    'pattern' => '/^[a-zA-Z]+$/',
    'message' => 'Do not enter zero or/and characters for Spare parts!',
    'on' => 'cost_spare_func'),

或使用如下默认验证：

public function rules()
{
    return array(
      [...]
      array('cost_spares','numerical',
        'integerOnly' => true,
        'min' => 1,
        'max' => 250,
        'tooSmall' => 'You must order at least 1 piece',
        'tooBig' => 'You cannot order more than 250 pieces at once',
        'message' => 'Do not enter zero or/and characters for Spare parts!',
        'on' => 'myScenario'),
      array('cost_labour','numerical',
        'integerOnly' => true,
        'min' => 1,
        'max' => 250,
        'tooSmall' => 'You must order at least 1 piece',
        'tooBig' => 'You cannot order more than 250 pieces at once',
        'message' => 'Do not enter zero or/and characters for Labour Charges!',
        'on' => 'myScenario'),
    );
}

  array('cost_spares', 'cost_spare_func',
    'message' => 'Do not enter zero or/and characters for Spare parts!',
    'on' => 'cost_spare_func'),

  array('cost_spares', 'match',
    'pattern' => '/^[a-zA-Z]+$/',
    'message' => 'Do not enter zero or/and characters for Spare parts!',
    'on' => 'cost_spare_func'),

这是出于设计-一个记录一次只能分配一个场景。当然，它会覆盖ist，因为您先将

cost\u spare\u func

设置为场景，然后将

cost\u labour\u func

设置为实际场景。@DCoder，我想在提交表单时同时显示这两个验证。@Jurik，你能告诉我场景和实际场景吗？如何实现这两个功能才能正确验证？当然，让我来实现你的想法。实现后，我发现“cost\u spare\u func”和“cost\u labour\u func”两个函数不是同时工作的，而是一次工作得很好。我编辑了我的答案。这是我的错误-您只能进行一次检查-因此只能通过

匹配进行检查

或通过

功能进行检查

-而不是同时进行检查。但在我看来，这可能更符合你的需要。
