Zend framework zend中的视图渲染未按预期正常工作

Zend framework zend中的视图渲染未按预期正常工作,zend-framework,Zend Framework,我的zend布局和脚本都很好。但是当我在IndexController的init函数中写入$this->view->render（“header.phtml”）时，它不会在屏幕上显示任何内容，而当我写入echo（$this->view->render（“header.phtml”）；它会显示我的header.phtml文件。这是我的IndexController 类IndexController扩展Zend\u控制器\u操作 { 变量$crt\U theme被设置为“默认值”。render（）正

我的zend布局和脚本都很好。但是当我在IndexController的init函数中写入$this->view->render（“header.phtml”）时，它不会在屏幕上显示任何内容，而当我写入echo（$this->view->render（“header.phtml”）；它会显示我的header.phtml文件。这是我的IndexController

类IndexController扩展Zend\u控制器\u操作 {

变量$crt\U theme被设置为“默认值”。

render（）
正在按预期工作；它返回一个字符串，然后您应该
回显该字符串

但是，直接在控制器中渲染是非常罕见的。至少，您应该从
视图/scripts/index/index.phtml
渲染页眉和页脚，尽管使用会更好。如果您使用
Zend_应用程序
，那么您可以通过添加以下内容开始使用
Zend_布局
：


<?php
$this->headMeta()->appendHttpEquiv('Content-Type', 'text/html;charset=utf-8');
$this->headTitle()->setSeparator(' - ');
$this->headTitle('My website');
?>
<!DOCTYPE html>
<html> 
<head>
    <?php echo $this->headMeta(); ?> 
    <?php echo $this->headTitle(); ?>
    <!-- Other <head> elements and view helpers here -->
</head>
<body>
<div id="content">
    <?php echo $this->layout()->content; ?>
</div>
</body>
</html>


到您的
应用程序/config/application.ini
文件。然后，您需要创建一个
应用程序/layouts/scripts/layout.phtml
文件，该文件可能如下所示：


resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts/"



Rob的回答是正确的，尽管您可能需要更多信息，因为您似乎正在努力使这个问题变得复杂。
ZF作为MVC使用时，有放置布局和使用布局的默认设置的位置。

如果使用Zend_工具命令行界面，请从命令开始：
zf enable layout
，该工具将向项目中添加默认目录和默认layout.phtml。

在application.ini中，它将添加以下行：


resources.layout.layout = master


并在该路径上添加文件
layout.phtml


如果需要更改默认布局的名称，请使用脚本名称添加这一行，而不使用.phtml


View Settings
;*************
resources.view[]=
resources.view.charset = "UTF-8"
resources.view.encoding = "UTF-8"
resources.view.doctype = "HTML5"
resources.view.language = "en"
resources.view.contentType = "text/html; charset=UTF-8"


使用此文件的方法尽可能多，但下面是我如何使用它的示例。

我喜欢在application.ini文件中设置我的项目默认值，这样如果我需要更改任何内容都很容易


protected function _initView() {
        //Initialize view
        $view = new Zend_View();

        $view->addHelperPath('/../library/Application/View/Helper');

        $view->doctype(Zend_Registry::get('config')->resources->view->doctype);

        $view->headTitle('Our Home');

        $view->headMeta()->appendHttpEquiv('Content-Type', Zend_Registry::get(
                        'config')->resources->view->contentType);
        $view->headLink()->setStylesheet('/css/normalize.css');
        $view->headLink()->appendStylesheet('/css/blueprint/src/liquid.css');
        $view->headLink()->appendStylesheet('/css/blueprint/src/typography.css');
        $view->headLink()->appendStylesheet(
                '/javascript/mediaelement/build/mediaelementplayer.css');
        $view->headLink()->appendStylesheet('/css/main.css');
        $view->headLink()->appendStylesheet('/css/nav.css');
        $view->headLink()->appendStylesheet('/css/table.css');

        //add javascript files
        $view->headScript()->setFile('/javascript/mediaelement/build/jquery.js');
        $view->headScript()->appendFile('/javascript/modernizr.js');

        //add it to the view renderer
        $viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper(
                        'ViewRenderer');
        $viewRenderer->setView($view);
        //Return it, so that it can be stored by the bootstrap
        return $view;
    }


然后在我的引导中，我设置了我想要使用的视图，我在这里这样做，这样如果我有多个布局（我通常这样做），就可以很容易地在一个地方更改css或js文件

                </nav>

                        if (count($this->messages) > 0) {
                            printf("<h3 id='flash'>%s</h3>", $this->messages[0]);
                        }
                        ?>
                    </div>
                    <?php echo $this->layout()->content; ?><!-- Default placeholder, where views are rendered -->

                    <div id="adminMenu">

            </footer>
        </section>
        <?php echo $this->inlineScript() ?><!-- placeholder -->
    </body>
</html>


请注意所有这些headLink（）、headScript（）和docType（）条目，它们是设置数据的位置，将在布局中使用

现在在布局中，来自其他基于动作的脚本的实际内容通常由占位符
$this->layout（）->content


$this->_helper->layout->setLayout('myOtherLayout');


这样做将更改控制器中每个操作的布局。为了更具选择性，您可以使用条件，如：


我真的不确定您想做什么。
render（）
方法应该返回呈现的HTML，而不是显示它。如果您正在寻找一种在Zend中布局模板的方法，您可能想看看Zend_layout，了解如何正确地执行此操作。

protected function _initView() {
        //Initialize view
        $view = new Zend_View();

        $view->addHelperPath('/../library/Application/View/Helper');

        $view->doctype(Zend_Registry::get('config')->resources->view->doctype);

        $view->headTitle('Our Home');

        $view->headMeta()->appendHttpEquiv('Content-Type', Zend_Registry::get(
                        'config')->resources->view->contentType);
        $view->headLink()->setStylesheet('/css/normalize.css');
        $view->headLink()->appendStylesheet('/css/blueprint/src/liquid.css');
        $view->headLink()->appendStylesheet('/css/blueprint/src/typography.css');
        $view->headLink()->appendStylesheet(
                '/javascript/mediaelement/build/mediaelementplayer.css');
        $view->headLink()->appendStylesheet('/css/main.css');
        $view->headLink()->appendStylesheet('/css/nav.css');
        $view->headLink()->appendStylesheet('/css/table.css');

        //add javascript files
        $view->headScript()->setFile('/javascript/mediaelement/build/jquery.js');
