在zend_form中设置路由Router

设置好路由之后怎么使用呢？在控制器中有redirection 控制器助手，在视图中有url视图助手

Naneau在这篇博文中使用$route->assemble()设置表单的url

/**
 * set the action based on a route
 *
 * @param array $params
 * @param string $routeName
 * @param bool $reset
 */
public function setRouteAction($params = array(), $routeName = null, $reset = false)
{
    $frontController = Zend_Controller_Front::getInstance();
    //the FC
    
    $router = $frontController->getRouter();
    //the router (assumes rewrite router)

    if ($reset) {
        $routeName = 'default';
    }
    //hmm... this may lead to unexpected results
    //but so will getting the current route name
        
    if ($routeName == null) {
        try {
            $routeName = $router->getCurrentRouteName();
        } catch (Zend_Controller_Router_Exception $e) {
            $routeName = 'default';
        }
    }
    //requested routename/default
    
    $route = $router->getRoute($routeName);
    //the current route
    
    $action = rtrim($frontController->getBaseUrl(), '/') . '/';
    $action .= $route->assemble($params, $reset);
    
    $this->setAction($action);
}

注意getCurrentRouteName(),getRoute(),assemble()方法的使用 

$params = array(
    'module' => 'blog',
    'controller' => 'post',
    'action' => 'read'
    'id' => 13
);
$route = $router->getRoute('default');
$url = $route->assemble($params, true);
//create a url using just the params set in $params
//this will look like blog/post/read/id/13

assemble的第2个参数为可选的boolean,表示是否重置当前请求变量
