php - 为什么多个场景在 Yii 中不起作用？

Question

我在我的应用程序中使用了多个场景，但遇到的问题是每次最后一个场景都会覆盖第一个场景。

型号:

public function rules()
{
    return array(
      [...]
      array('cost_spares', 'cost_spare_func', 'match',
        'pattern' => '/^[a-zA-Z]+$/',
        'message' => 'Do not enter zero or/and characters for Spare parts!',
        'on' => 'cost_spare_func'),
      array('cost_labour', 'cost_labour_func', 'match',
        'pattern' => '/^[a-zA-Z]+$/',
        'message' => 'Do not enter zero or/and characters for Labour Charges!',
        'on' => 'cost_labour_func'),
    );
}

Controller :

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

关于 documents :

Firstly it is important to note that any rules not assigned a scenario will be applied to all scenarios.

所以我认为您可能不需要场景，只需使用通用规则/验证即可。

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'),
    );
}

然后在你的 Controller 中你只需要写:

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

编辑:
关于this document ，我只看到您只需要 numerical 输入。所以这可能更适合您的需求。由于两者都得到了相同的支票，您可以只进行一次支票，然后将消息传递给它。但就目前而言，这应该可行。

额外:
就像您写的那样，您的规则中还有另一个错误。

  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'),

那是不可能的。您不能混合使用规则验证函数和默认验证，例如 match。

这意味着您只能像这样定义一个验证函数:

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

或使用这样的默认验证:

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