Answer 1

You can simply CURRENT_TIMESTAMP in your database, but unfortunately it only works for 1 row in a table

Answer 2

Instead of

<?php echo $form->textField($model,'createtime'); ?>

Use

<?php echo $form->hiddenField($model,'createtime'); ?>

---

Alternatively in your model, you can set default values in afterConstruct():

protected function afterConstruct() {

    parent::afterConstruct();

    if($this->hasAttribute('createtime') && empty($this->createtime))
        $this->createtime = new Date();

---

Another way to do it is set the default value in the database to CURRENT_TIMESTAMP.

Answer 3

You can do that in Your controller. For example in yuor Controller` create action

 public function actionCreate()
 {
 $model=new Product;
 $model->createtime = strtotime('Now');
 if(isset($_POST['Product']))
 {........}
 .......
 }

And remove from _from.php

 <div class="row">
  <?php echo $form->labelEx($model,'createtime'); ?>
  <?php echo $form->textField($model,'createtime'); ?>
  <?php echo $form->error($model,'createtime'); ?>
 </div>

Answer 4

I think better put assign value on Model. you can use beforeSave() to assign value into 'createtime' before model saved.

on # protected/models/YourModel.php add method like this :

public function beforeSave(){
    if($this->isNewRecord){
        $this->createtime = date('Y-m-d H:i:s');
    }else{
        $this->modifiedtime = date('Y-m-d H:i:s'); 
       //just case if you have modifiedtime field 
    }
    return parent::beforeSave();
} 

after that, just removed this code from view form.

<div class="row">
     <?php echo $form->labelEx($model,'createtime'); ?>
     <?php echo $form->textField($model,'createtime'); ?>
     <?php echo $form->error($model,'createtime'); ?>
</div>

Answer 5

Use simply:

date('Y-m-d H:i:s')
