Question

有没有办法在Zend Framework中使用常规的mysql select语句，而无需使用Zend_Db :: factory

下面的代码在我的Model类中，它扩展了Zend_Db_Table_Abstract

我现在可以这样做（有效）：

    $db = Zend_Db::factory('Pdo_Mysql', array(
                'host' => 'localhost',
                'username' => 'dbuser',
                'password' => 'dbuserpass',
                'dbname' => "somedbname"
            ));

    $select = "SELECT iv.* 
                FROM image_variations AS iv
                LEFT JOIN images AS i ON (i.image_id = iv.image_id)
                LEFT JOIN product_images AS pi ON (pi.image_id = iv.image_id)
                WHERE pi.pid = '$pid'
                && iv.image_type_id = '$image_type_id' ";

    $stmt = $db->query($select);
    $rows = $stmt->fetchAll();
    return $rows;

我想这样做：

    $select = "SELECT iv.* 
                FROM image_variations AS iv
                LEFT JOIN images AS i ON (i.image_id = iv.image_id)
                LEFT JOIN product_images AS pi ON (pi.image_id = iv.image_id)
                WHERE pi.pid = '$pid'
                && iv.image_type_id = '$image_type_id' ";

    $stmt = $this->query($select);
    $rows = $stmt->fetchAll();
    return $rows;

所以我不必总是在每个方法中定义db变量并且在整个地方都有mysql密码。有没有办法使用$ this而不必实例化一个新的$ db Zend_DB Factory ??

好的想通了。解决方案不是很优雅，但可以工作并且便携。

我的设置包含多个DB，因此在Bootstrap.php中我有：

protected function _initDatabase() {
    $resource = $this->getPluginResource('multidb');
    $resource->init();

    Zend_Registry::set('db', $resource->getDb('db'));
    Zend_Registry::set('shopdb', $resource->getDb('shopdb'));
}

在Application.ini中

resources.multidb.db.adapter = PDO_MYSQL
resources.multidb.db.host = 127.0.0.1
resources.multidb.db.username = user
resources.multidb.db.password = userpassword
resources.multidb.db.dbname = dbone
resources.multidb.db.isDefaultTableAdapter = true
resources.multidb.db.default = true


resources.multidb.shopdb.adapter = PDO_MYSQL
resources.multidb.shopdb.host = 127.0.0.1
resources.multidb.shopdb.username = user
resources.multidb.shopdb.password = userpassword
resources.multidb.shopdb.dbname = dbtwo
resources.multidb.shopdb.isDefaultTableAdapter = false

index.php中的

$config = new Zend_Config_Ini(APPLICATION_PATH . "/configs/application.ini");
Zend_Registry::set('settings', $config);

然后（模型中不是很优雅的位）添加一个init（）方法

protected $db;

public function init() {
    $settings = Zend_Registry::get('settings');
    $adapter = $settings->production->resources->multidb->shopdb->adapter;
    $params = array(
        'host' => $settings->production->resources->multidb->shopdb->host,
        'username' => $settings->production->resources->multidb->shopdb->username,
        'password' => $settings->production->resources->multidb->shopdb->password,
        'dbname' => $settings->production->resources->multidb->shopdb->dbname,
    );
    $this->db = Zend_Db::factory("$adapter", $params);
}

然后你可以在Model类的其他方法中使用$ this-＆gt; db，例如：

public function getProductImages($pid, $image_type_id) {

    $select = "SELECT iv.* 
                FROM image_variations AS iv
                LEFT JOIN images AS i ON (i.image_id = iv.image_id)
                LEFT JOIN product_images AS pi ON (pi.image_id = iv.image_id)
                WHERE pi.pid = '$pid'
                && iv.image_type_id = '$image_type_id' ";

    $stmt = $this->db->query($select);
    $rows = $stmt->fetchAll();
    return $rows;
}

它有效，但似乎应该有更简单的方法...
