控制器之间的Symfony调用功能 [英] Symfony calling functions between controllers

问题描述

有人可以指导我如何完成跨控制器变量交换和/或函数调用吗?

Can anyone give me direction on how to accomplish cross controller variable exchange and/or function calls?

我是Symfony的新手，我有一个相当复杂的练习示例站点，该站点具有两个控制器-PageController和BlogController.

I'm new to Symfony and I have a reasonably complex practice sample site which has two controllers - PageController and BlogController.

PageController可以执行一些操作来生成我的主页，关于和联系页面.主页仅包含博客列表.

PageController has actions to generate my home, about and contact page. The home page simply has a list of blogs.

BlogController具有与CRUD相关的所有功能-创建，删除等

The BlogController has all the CRUD related functions - create, delete etc

我的问题是我想从PageController调用我的BlogController:createAction函数，这样我就可以在主页上博客列表上方显示一个博客创建表单，或者只传递包含新博客表单数据的变量.

My issue is that I want to call my BlogController:createAction function from the PageController so I can present a blog create form above the blog listings on the homepage OR just pass the variable containing the new blog form data.

此外，我需要找到一种解决方案，以允许表单提交并通过AJAX刷新列表.

In addition, I need to find a solution which will allow the form to submit and the listings to refresh via AJAX.

推荐答案

直接使用向前方法

$response = $this->forward('AcmeDemoBundle:Blog:myFunction', array(
    'name'  => $name,
));

http://symfony.com/doc/current/book/controller.html#forwarding-to-another-controller

或者，您也可以将博客控制器定义为服务.

Or alternatively, you could define the blog controller as a service.

service.yml

service.yml

services:
    your_service:
        class: Acme\DemoBundle\Controller\BlogController

然后您就可以使用

$service = $this->get('your_service');
$service->myFunction();

您还可以考虑设置表格工厂服务(高级一点)

You could also look into setting up a form factory service (bit more advanced)

更新:

在您发布帖子之后，我实施了一项服务，但出现以下错误:

Following your post I implemented the a service but got the following error:

Error: Call to a member function get() on a non-object

当我在服务声明中添加以下行时，此问题已解决:

This got fixed when I added the following line to the service declaration:

calls:
         - [ setContainer, [ @service_container ]]
