Yii CActiveForm examples
Last updated:Simple Default Form
Assuming you have sent a variable called $model (with one attribute called name) from your controller to this view when you rendered it:
<?php $form=$this->beginWidget('CActiveForm', [
'id'=>'my-form',
'enableAjaxValidation'=>true,
'clientOptions'=>[
'validateOnSubmit'=>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,'name'); ?>
<?php echo $form->textField($model,'name'); ?>
<?php echo $form->error($model,'name'); ?>
</div>
<br />
<?php echo CHtml::submitButton('Save Changes'); ?>
<?php $this->endWidget(); ?>
Focus on an Element
<?php $form=$this->beginWidget('CActiveForm', array(
'enableAjaxValidation'=>true,
'clientOptions'=>[
'validateOnSubmit'=>true
],
'focus'=>[$model,'name'],
)); ?>
//...form elements
<?php $this->endWidget(); ?>
Default Selected Item in DropDownList Element
To have the second option on a DropDownList selected by default, you need something like this: (wildly useful IMO)
<?php
echo $form->dropDownList(
$model,
'language',
CHtml::listData( Language::model()->findAll(),'id','name' ),
[
'class' => 'my-drop-down',
'options' => [
'2' => [ 'selected' => true ]
]
]);
?>
DatePicker Element for date Attribute in a Form
<?php $this->widget('zii.widgets.jui.CJuiDatePicker',
[
'model'=>$model,
'attribute'=>'start_date',
'options'=>[
'showAnim'=>'fold',
'autoSize'=>true,
'dateFormat'=>'dd/mm/yy',
'defaultDate'=>'10/12/2011',
],
'htmlOptions'=>[
'value'=>date_format(new DateTime,'d/m/Y'),
],
]);
?>
P.S.: Note that you may need to convert dates from one type to another before saving it to your database. Use PHP's date_format function for that.
