上面是我的 header 小部件视图，您可以在业务中看到，我想从我的数据库中获取类别，这是静态的，我想使其成为动态的。

<?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(

    }

     */
    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);
    }
}

以上是我的品类模型

Answer 1

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>
