Question

我对选择验证规则有疑问。

我将验证规则粘贴在模型中

public $validate = array(
  'sentence_fields'=> array(
    'select_chapter' => array(
      'field'=>'select_chapter',
      'label'=>'Select chapter',
      'rules'=>'required|integer'
    ),
    'source_sentence' => array(
      'field'=>'source_sentence',
      'label'=>'Source',
      'rules'=>'trim|required|max_length[500]'
    ),
    'translated_sentence' => array(
      'field'=>'translated_sentence',
      'label'=>'Translation',
      'rules'=>'trim|required|max_length[500]'
    ),
    'translated_translation' => array(
      'field'=>'translated_translation[]',
      'label'=>'Select another translation',
      'rules'=>'trim|max_length[500]'
    )
  )
);

然后在控制器中调用它

$validate = $this->sentence_model->validate['sentence_fields'];
$this->form_validation->set_rules($validate);

那是针对create方法的，但我有一个不需要select_chapter规则集的更新方法。

是否有一种简单的方法来调用此规则集（sentence_fields），但为我的更新方法排除select_chapter？

感谢。

Answer 1

如果你想将select_chapter排除在我的更新方法之外。只需使用数组的unset()方法就可以了。

$validate = $this->sentence_model->validate['sentence_fields'];

unset($validate['sentence_fields']['select_chapter ']);//unsets your array
$this->form_validation->set_rules($validate);

由于上述方法有效，我建议将其作为一种功能，以提高可读性和易用性。为此，请查看以下内容

public $validate = array(
  'sentence_fields'=> array(
    'select_chapter' => array(
      'field'=>'select_chapter',
      'label'=>'Select chapter',
      'rules'=>'required|integer'
    ),
    'source_sentence' => array(
      'field'=>'source_sentence',
      'label'=>'Source',
      'rules'=>'trim|required|max_length[500]'
    ),
    'translated_sentence' => array(
      'field'=>'translated_sentence',
      'label'=>'Translation',
      'rules'=>'trim|required|max_length[500]'
    ),
    'translated_translation' => array(
      'field'=>'translated_translation[]',
      'label'=>'Select another translation',
      'rules'=>'trim|max_length[500]'
    )
  )
);

public function formValidationRules($validation, $unset = array()) {
     if($unset) {
        return $this->unsetValidation($unset);
     } else {
        return $this->validate[$validation];
     }
}

private function ($unset) {
  $validations = $this->validate[$validation];
  foreach($unset as $key)
  {
     unset($validations[$key]);
  }
  return $validations;
}

这样您可以按照以下方式进行验证：

$validate = $this->sentence_model->formValidationRules('sentence_fields', ['select_chapter']);

$this->form_validation->set_rules($validate);
