在yii中创建记录时模型验证不起作用

Question

I really don't know why is it happening my model validations are not working while creating record in yii. doesn't display any errors . The thing is if any of the required field is empty though it passes to the display page not displaying errors but it doesn't insert the record as all required field a not filled.

My need is display errors in the same form i.e., validations should not pass if required fields are empty.

validation works with no issues in update, issues with create form

but it inserts the record if all required field are filled.

errors displayed in update are black not red as default by yii ...... is it due to the extension am using

model rules

        array('name, category, model, brand, description, price', 'required'),
        array('pimg', 'file','types'=>'jpg','on'=>'create'),
        array('pimg', 'file','types'=>'jpg','on'=>'update', 'allowEmpty'=>true),

controller for create

     $model=new controllername;

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

    if(isset($_POST['controllername']))
    {
        $model->attributes=$_POST['controllername'];
        $model->pimg=CUploadedFile::getInstance($model,'pimg');
        $fileName = $model->pimg;


        if($model->save())
            $model->pimg->saveAs('images/'.$fileName);
            $this->redirect(array('display','id'=>$model->productid));

    }

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

view

  <?php $form=$this->beginWidget('CActiveForm',array(
   'id'=>'form_name',
     'enableAjaxValidation'=>false,
    'htmlOptions'=>array('enctype'=>'multipart/form-data'),
      )); ?>

        <p class="note">Fields with <span class="required">*</span> are required.</p>





    <?php echo $form->labelEx($model,'name'); ?>
    <?php echo $form->textField($model,'name',array('size'=>60,'maxlength'=>60)); ?>
    <?php echo $form->error($model,'name'); ?>

    <?php echo $form->labelEx($model,'model'); ?>
    <?php echo $form->textField($model,'model',array('size'=>30,'maxlength'=>30)); ?>
    <?php echo $form->error($model,'model'); ?>


  <?php echo $form->labelEx($model,'description'); ?>
    <?php echo $form->textField($model,'description',array('size'=>60,'maxlength'=>256)); ?>
    <?php echo $form->error($model,'description'); ?>



    <?php echo $form->labelEx($model,'pimg'); ?>
    <?php echo $form->hiddenField($model,'pimg',array('length'=>222)); ?>
    <?php echo $form->fileField($model, 'pimg',array('id'=>'imgInput',)); ?>

    <?php echo $form->error($model,'pimg'); ?>



    <?php echo $form->labelEx($model,'category'); ?>
    <?php echo $form->dropDownList($model,'category',$model->getCat()); ?>
    <?php echo $form->error($model,'category'); ?>


<?php echo $form->labelEx($model,'brand'); ?>
    <?php echo $form->textField($model,'brand',array('size'=>30,'maxlength'=>30)); ?>
    <?php echo $form->error($model,'brand'); ?>

    <?php echo $form->labelEx($model,'price'); ?>
    <?php echo $form->textField($model,'price'); ?>
    <?php echo $form->error($model,'price'); ?>






 <?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?>


 <?php $this->endWidget(); ?>

Answer 1

if you redirect a page, the error will not be shown,

your code redirects anyway, if (save()) or not .

add a {} after your if

if($model->save())
{
            $model->pimg->saveAs('images/'.$fileName);
            $this->redirect(array('display','id'=>$model->productid));
}
