上面是我的标题小部件视图，你可以在业务中看到，我想从我的数据库中获取类别，这是静态的，我想让它变得动态。
<?php
/**
* This is the model class for table "category".
*
* The followings are the available columns in table 'category':
* @property integer $id
* @property string $category_name
*
* The followings are the available model relations:
* @property SubCategoryBusiness[] $subCategoryBusinesses
*/
class Category extends CActiveRecord
{
/**
* @return string the associated database table name
*/
public function tableName()
{
return 'category';
}
/**
* @return array validation rules for model attributes.
*/
public function rules()
{
// NOTE: you should only define rules for those attributes that
// will receive user inputs.
return array(
array('category_name', 'length', 'max'=>45),
// The following rule is used by search().
// @todo Please remove those attributes that should not be searched.
array('id, category_name', 'safe', 'on'=>'search'),
);
}
/**
* @return array relational rules.
*/
public function relations()
{
// NOTE: you may need to adjust the relation name and the related
// class name for the relations automatically generated below.
return array(
'subCategoryBusinesses' => array(self::HAS_MANY, 'SubCategoryBusiness', 'category_id'),
);
}
/**
* @return array customized attribute labels (name=>label)
*/
public function attributeLabels()
{
return array(
'id' => 'ID',
'category_name' => 'Category Name',
);
}
/**
* Retrieves a list of models based on the current search/filter conditions.
*
* Typical usecase:
* - Initialize the model fields with values from filter form.
* - Execute this method to get CActiveDataProvider instance which will filter
* models according to data in model fields.
* - Pass data provider to CGridView, CListView or any similar widget.
*
* @return CActiveDataProvider the data provider that can return the models
* based on the search/filter conditions.
*/
public function search()
{
// @todo Please modify the following code to remove attributes that should not be searched.
$criteria=new CDbCriteria;
$criteria->compare('id',$this->id);
$criteria->compare('category_name',$this->category_name,true);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
/**
* Returns the static model of the specified AR class.
* Please note that you should have this exact method in all your CActiveRecord descendants!
* @param string $className active record class name.
* @return Category the static model class
*/
public static function model($className=__CLASS__)
{
return parent::model($className);
}
}
以上是我的类别模型
答案 0 :(得分：0)
我是通过cdbcriteria完成的，这是我的headerwidget视图
<ul>
<?php $criteria = new CDbCriteria(array('order'=>'id ASC'));
$model = Category::model()->findAll($criteria);
$name=array();
$id=array();
foreach ($model as $list) {
$names[] = $list->category_name;
$id[]=$list->id;
}
for($i=0;$i<8;$i++){
?>
<li>
<a href="<?php echo Yii::app()->request->baseUrl;?>/<?php echo $id[$i];?>.php"><?php echo $names[$i];?> </a>
</li>
<?php }?>
</ul>
