dropdown yii

lets consider two tables Employee and Department, Employee column field Department-id refers to Department etc.. and you want to display a dropdrop rather than textfield in the create view. 


protected/views/Department/_form.php

beginWidget('CActiveForm', array(

'id'=>'employee-form',

'enableAjaxValidation'=>false,

)); ?>

Fields with * are required.

errorSummary($model); ?>

labelEx($model,'departmentId'); ?>

textField($model,'departmentId'); ?>

                dropDownList($model,'departmentId', CHtml::listData(TestDepartment::model()->findAll(), 'id', 'departmentName')); ?>

error($model,'departmentId'); ?>

labelEx($model,'firstName'); ?>

textField($model,'firstName',array('size'=>20,'maxlength'=>20)); ?>

error($model,'firstName'); ?>

labelEx($model,'lastName'); ?>

textField($model,'lastName',array('size'=>40,'maxlength'=>40)); ?>

error($model,'lastName'); ?>

labelEx($model,'email'); ?>

textField($model,'email',array('size'=>60,'maxlength'=>60)); ?>

error($model,'email'); ?>

labelEx($model,'ext'); ?>

textField($model,'ext'); ?>

error($model,'ext'); ?>

labelEx($model,'hireDate'); ?>

textField($model,'hireDate'); ?>

error($model,'hireDate'); ?>

labelEx($model,'leaveDate'); ?>

textField($model,'leaveDate'); ?>

error($model,'leaveDate'); ?>

isNewRecord ? 'Create' : 'Save'); ?>

endWidget(); ?>

Show more records per page Yii

to display more records in CGrid in Yii simply add one line to your model :)


protected/models/Product.php


/*** Retrieves a list of models based on the current search/filter conditions.
* @return CActiveDataProvider the data provider that can return the models based on the search/filter conditions.*/


public function search()
{
// Warning: Please modify the following code to remove attributes that should not be searched.
$criteria=new CDbCriteria;


$criteria->compare('Product_Code',$this->Product_Code,true);
$criteria->compare('Name',$this->Name,true);
$criteria->compare('Short_Description',$this->Short_Description,true);



return new CActiveDataProvider(get_class($this), array(
'criteria'=>$criteria,  
                'pagination'=>array('pageSize'=>20,), //framework/web/CPagination.php
));
}
