Question

问题很简单，但为什么它对我来说很复杂。我也写过数据验证。但是对于空字段，它也接受输入。请检查我的action.php中是否有错误。

型号/ action.php的

func prepareChangePasswordField() {
    enterPasswordText.placeholder = "Password"
    enterPasswordText.detailColor = Color.red
    enterPasswordText.delegate = self
    enterPasswordText.placeholderNormalColor = UIColor.lightGray
    enterPasswordText.placeholderActiveColor = Color.blue.base
    enterPasswordText.dividerNormalColor = Color.grey.base
    enterPasswordText.dividerActiveColor = Color.blue.base
    enterPasswordText.isVisibilityIconButtonEnabled = true
    enterPasswordText.visibilityIconButton?.tintColor = Color.grey.base.withAlphaComponent(passwordText.isSecureTextEntry ? 0.2 : 1.0)

}

func prepareConfirmPasswordField() {
    confirmPasswordText.placeholder = "Confirm password"
    confirmPasswordText.detailColor = Color.red
    confirmPasswordText.delegate = self
    confirmPasswordText.placeholderNormalColor = UIColor.lightGray
    confirmPasswordText.placeholderActiveColor = Color.blue.base
    confirmPasswordText.dividerNormalColor = Color.grey.base
    confirmPasswordText.dividerActiveColor = Color.blue.base
    confirmPasswordText.isVisibilityIconButtonEnabled = true
    confirmPasswordText.visibilityIconButton?.tintColor = Color.grey.base.withAlphaComponent(passwordText.isSecureTextEntry ? 0.2 : 1.0)

    //self.view.addSubview(userNameText)
    //view.layout(emailTextField).center(offsetY: -passwordField.height - 60).left(20).right(20)
}

查看/操作/ index.ctp

<?php
App::uses('AppModel', 'Model');

class Actions extends AppModel {
  public $validate = array(
        'value_to_plot' => array(
          'required'=>true,
            'message' => 'atleast select one measure'
        ),
        'column_name' => array(
          'required'=>true,
            'rule'=>array('notBlank'),
            'message' => 'atleast select one table'
          )

      );
}

?>

控制器/ ActionsController.php

<div align="center">
<fieldset>
  <?php  echo $this->Form->create('valueToSend',array('type' => 'get'));?>
    <?php if(isset($_GET['table_name'])){ ?>
      <table class="table table-bordered table-hover table-striped">
        <?php echo $this->Form->hidden('table_name', array('hiddenField' => true, 'value'=> $_GET['table_name'],'id'=>'table_name'));
       echo $this->Form->hidden('chart', array('hiddenField' => true, 'value'=> "column3d",'id'=>"chart"));
        ?>
          <tr>
            <th>MEASURES</th>
            <td>
              <?php  echo $this->Form->select('value_to_plot',$measures1,array('class'=>'form-control','id'=>'measures','required'=>true),['empty' => 'choose one']);?>
            </td>

          </tr>
          <tr>
            <th>DIMENSIONS</th>
            <td>
              <?php echo  $this->Form->select('column_name[]',$measures2,array('multiple'=>'true','class'=>'form-control','id'=>'dimensions','required'=>true),['empty' =>'choose one']);?>
            </td>

          </tr>
        </table>
      <div style="text-align:center">
        <?php  echo $this->Form->end('submit'); ?>
      </div>
    <?php } ?>
</fieldset>
</div>

Answer 1

这将验证并保存您的数据

if ($this->request->is('post')) {
     $this->Actions->set($this->request->data);
     if ($this->Actions->save($this->request->data)) {
            // Set a session flash message and redirect.
     }
}

Answer 2

我认为你混淆了''required'=＆gt; true“和''allowEmpty'=＆gt; true”。前者意味着无法保存记录而不将该字段包含在更新的字段列表中，无论它是否包含实际数据。后者，我认为是你真正的意思，允许一个字段为空，虽然它不会强制声明。
