php - php yii将错误发送到actionCreate上的表单

我想向表单上的字段Components_original_asset_number发送错误。我将如何实现这一目标。在 Controller 功能中，我正在检查是否存在，如果我不想要在表单或消息上显示错误。 original asset number是我在此表单上显示的单独模型的一部分。

public function actionCreate()
{
    $model = new Components;
    $model_fixedAsset = new FixedAsset;
    $model_comAsset = new ComAsset;

    // Uncomment the following line if AJAX validation is needed
    // $this->performAjaxValidation($model);

    if(isset($_POST['Components']))
    {
        $model->attributes=$_POST['Components'];
        $fixedAssetId = null;


        // Check if asset exist and get PK
        if( $_POST['Components']['original_asset_number'] != "" ){
            //print_r($_POST['Components']);
            $criteria = new CDbCriteria;
            $criteria->condition = "(original_asset_number = :original_asset_number)";
            $criteria->params = array(":original_asset_number" =>  $_POST['Components']['original_asset_number'] );
            $fixedAssetRow = FixedAsset::model()->find($criteria);
            //print_r($fixedAssetRow);
            if($fixedAssetRow){
                $fixedAssetId = $fixedAssetRow->fixed_asset_id;
            }
            //echo $fixedAssetId;
        }

        if($fixedAssetId){

        /*if($model->save())
            $this->redirect(array('view','id'=>$model->component_id));*/

        // Create com_asset record

        }else{
            //no asset found return error message to input corect asset number or create asset in navision and run php script to update mysql db
        }
    }

    $this->render('create',array(
        'model'=>$model,
        'model_fixedAsset'=>$model_fixedAsset,
        'model_comAsset'=>$model_comAsset,
    ));
}

Answer 1

您应该在模型中添加“original_asset_number”作为变量，并设置所需的验证规则。然后您可以使用以下行设置错误

$model->addError('original_asset_number', " no asset found return error message to input corect asset number or create asset in navision and run php script to update mysql  ");

另外，您可以使用以下方式显示该字段和错误。

<?php echo $form->errorSummary($model); ?>

要么

    <div class="row">
    <?php echo $form->labelEx($model,'original_asset_number'); ?>
    <?php echo $form->textField($model,'original_asset_number',array('size'=>60,'maxlength'=>255)); ?>
    <?php echo $form->error($model,'original_asset_number'); ?>
</div>
