zend framework class初始化的问题

[hxsying]

<?php
class Db extends Zend_Db_Table {
function __construct($name='',$primary=''){
echo "*****$name******";
}
public function setName($name){
$this->_name = $name;
}
public function setPrimary($primary){
$this->_primary = $primary;
}
}

function indexAction(){
$artiClass = new Db('b_arti_class','id');

}

的结果
***********
Catchable fatal error: Argument 1 passed to Zend_Db_Select::__construct() must be an instance of Zend_Db_Adapter_Abstract, null given, called in D:\Soft\wamp\www\library\Zend\Db\Table\Select.php on line 76 and defined in D:\Soft\wamp\www\library\Zend\Db\Select.php on line 163

来人呐

嗯嗯 没人

提示的错误是Zend_Db_Select这个类的构造失败，提交的必须是一个实例

[hxsying]

为什么不输出 *****b_arti_class****** 呢

在zend_db_table 的继承类里面最好不要用构造器，用另外一个类似构造器的方法
protected function _setup()
{
$this->_name = 'category';
parent::_setup();
}

[hm446434459]

如果你一定要用构造器，记得在子类中调用父类的构造器
public function __construct($name,$primary)
{
$this->_name = $name;
$this->_primary = $primary;
parent::__construct();
}

需要在配置文件中配置好数据库连接相关项.

你贴的代码和你的出错信息没关系，
重贴！

public function int($name,$primary){
$this->_name = $name;
$this->_primary = $primary;
parent::init ();
}
