运行时的Yii验证 - Yii validation at run time?

我有一个用户Model和一个permisssion模型。在用户表单中有主管和城市两个字段。在权限表中，我将required设置为1，不需要设置为0。

Permission table
user_role      supervisor      city
1                    1              1
2                    1              0
3                    0              0

现在我想当我从城市和主管的用户中选择一个角色时如果1则需要为该user_role设置激活的规则

<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'lms-user-form',
    'enableAjaxValidation'=>true,
)); ?>
    <p class="note">Fields with <span class="required">*</span> are required.</p>
    <?php echo $form->errorSummary($model); ?>
<div class="row">
        <?php echo $form->labelEx($model,'user_role'); ?>
        <?php echo $form->drodownList($model,'user_role',array(); ?>
        <?php echo $form->error($model,'user_role'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'user_first_name'); ?>
        <?php echo $form->textField($model,'user_first_name',array('size'=>40,'maxlength'=>40)); ?>
        <?php echo $form->error($model,'user_first_name'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'user_last_name'); ?>
        <?php echo $form->textField($model,'user_last_name',array('size'=>40,'maxlength'=>40)); ?>
        <?php echo $form->error($model,'user_last_name'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'user_password'); ?>
        <?php echo $form->textField($model,'user_password',array('size'=>40,'maxlength'=>40)); ?>
        <?php echo $form->error($model,'user_password'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'user_city'); ?>
        <?php echo $form->textField($model,'user_city',array('size'=>10,'maxlength'=>10)); ?>
        <?php echo $form->error($model,'user_city'); ?>
    </div>
<div class="row">
        <?php echo $form->labelEx($model,'user_supervisor'); ?>
        <?php echo $form->textField($model,'user_supervisor',array('size'=>10,'maxlength'=>10)); ?>
        <?php echo $form->error($model,'user_supervisor'); ?>
    </div>
    <div class="row buttons">
        <?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?>
    </div>
<?php $this->endWidget(); ?>
</div><!-- form -->

我使用了类似这样的东西，但这不起作用

    $permiss = Permission::model->findByAttributes(array('user_role'=>$model=>user_role));
    if($permiss->user_city && $permiss->user_supervisor){
    $model->rules(array('user_city','user_supervisor','required'));
    }
    elseif($permiss->user_city)
   {
    $model->rules(array('user_city','required'));
    }
 elseif($permiss->user_supervisor)
   {
    $model->rules(array('user_supervisor','required'));
    }

我知道addError，但我希望ajax validation发生

为什么不使用自定义验证?

你应该试试这个方法。

选项1:

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'lms-user-form',
    'enableAjaxValidation'=>true,
    'enableClientValidation'=>true,
    'clientOptions'=>array(
     'validateOnSubmit'=>true),
)); ?>

在你的动作中使用这个

$this->performAjaxValidation($model);

选项2:

添加如上和自定义验证:

array('user_role', 'customValidation'),
public function customValidation($attribute, $params)
    {
        $user_role = $this->attributes['user_role'];
        $permiss   = Permission::model()->findByAttributes(array('user_role' => $user_role));
        if ($permiss->user_city && $permiss->user_supervisor) {
            if ($this->user_city == '') {
                $this->addError('user_city', "User city cannot be blank.");
            }
            if ($this->user_supervisor == '') {
                $this->addError('user_supervisor',
                    "User supervisor cannot be blank.");
            }
        } else if ($permiss->user_city) {
            if ($this->user_city == '') {
                $this->addError('user_city', "User city cannot be blank.");
            }
        } elseif ($permiss->user_supervisor) {
            if ($this->user_supervisor == '') {
                $this->addError('user_supervisor',
                    "User supervisor cannot be blank.");
            }
        }
    }

还有一件事你需要添加表单名称在performAjaxValidation($model)方法。

在这两种方式ajax验证工作。希望能有所帮助
