I want to send an error to the field Components_original_asset_number on the form. How would I achieve this. In the controller function I am checking to see if it exists if not I want to display error on form or message. original asset number is part of a separate model which I am displaying on this form.
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

You should add the 'original_asset_number' in your model as variable and set required validation rule. Then you can use the following line to set error
$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 ");
Also, you use the following way to display the field and error.
<?php echo $form->errorSummary($model); ?>
or
<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>
