Zend和Smarty 3集成使用

标签: php zend-framework smarty zend-view

我正在尝试更改控制器中的布局内容,它似乎只是覆盖它,只是附加。

我使用Zend和Smarty构建了一个CMS。我有一个主要布局,显示每个页面的内容:

{$this->layout()->content}

虽然当我尝试使用新的内容区域覆盖控制器中的“内容”时,这会导致显示index / index.tpl和contact / contact.tpl:

$this->view->content = $this->view->display('contact/contact.tpl');

我知道我可以手动将内容分配给view smarty变量,虽然我想减少smarty中的赋值并使用Zend。

在我的application.ini

smarty.caching = 1
smarty.cache_lifetime = 14400
smarty.template_dir = PATH "/templates/default/"
smarty.compile_dir = PATH "/tmp/smarty_compile/"
smarty.plugins_dir = APPLICATION_PATH "/plugins/smarty/"
smarty.config_dir = ""
smarty.cache_dir = PATH "/tmp/smarty_cache/"
smarty.left_delimiter = "{"
smarty.right_delimiter = "}"

在我的bootstrap.php

protected function _initView()
{
    $view = new Web_View_Smarty($this->getOption('smarty'));
    $viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('ViewRenderer');
    $viewRenderer->setViewSuffix('tpl');
    $viewRenderer->setView($view);
    $this->bootstrap('layout');
    $layout = Zend_Layout::getMvcInstance();
    $layout->setViewSuffix('tpl');
    return $view;
}

在我的Smarty.php中

<?php
/**
 * Smarty template engine integration into Zend Framework

class Web_View_Smarty extends Zend_View_Abstract
{
/**

Zend文档中有Smarty实现。 Smarty很糟糕,任何模板引擎都很糟糕,并且会降低应用程序的速度。 使用zend原生视图。 请记住,PHP被发明为模板引擎。 http://framework.zend.com/manual/1.11/en/zend.view.scripts.html

答案 1 :(得分:0)

在模板中,您可以写

{$this->layout()->content}

这是布局助手的内容,它将呈现与每个动作关联的视图。

当您在控制器中编写

$this->view->content = $this->view->display('contact/contact.tpl');

您可以使用

为视图指定一个可以显示的变量
{$content}

在你聪明的模板中。

我认为你对这种排序方式有些困惑。看一下 http://framework.zend.com/manual/1.12/en/zend.layout.quickstart.html

无论如何,你的问题已经过去了,你已经选择了一个正确的答案,顺便说一句,这不是一个真正的答案,但是我无法过去而且什么都不说。使用Smarty和Zend很棒,Smarty更快,编译/缓存比Zend有更好的微调,两者之间的整合很简洁(由于依赖注入)。你可以在一个应用程序中拥有两个库的强大功能,所以去吧。
