试试这个

$usercriteria = new CDbCriteria();
$usercriteria->select = "university_name";
$usercriteria->condition = "university_id=$university_id";
$university = University::model()->findAll($usercriteria);

echo $university->university_name;

或者就像你第一次那样

$agent = University::model()->findByPK($university_id);
echo $agent-> university_name;

$agent = University::model()->findByPK($university_id);
echo $agent->university_name;

它应该是这样的：

$agent = University::model()->findByPK($university_id)->university_name;

试试看：

$university_name = University::model()->findByPK($university_id, array('select'=>'univeersity_name'))->university_name;

# Query: SElECT university_name FROM table_name where id=x;

而不是

$university_name = University::model()->findByPK($university_id)->university_name;

# Query: SElECT * FROM table_name where id=x;

第二个查询返回所有字段。所以最好避免那些字段是不必要的。

如果你需要在yii _views上查看，我已经在我的项目上实现了这个，我把它放在我的'_view.php'里面，地址是/protected/views/myTable/

$agent = University::model()->findByPK($data->id_university/*this is the PK field name*/);
echo $agent->university_name /*university field name*/;

再次为我糟糕的英语道歉：o

可以这样做：

$agent = University::model()->findAllByAttributes(array('field3'),"WHERE `id` = :id", array(':id' => $university_id));

findByAttributes的第一个参数是您希望它返回的属性数组。如果保留为空，它将返回all（*）。
