为我们的Hello World模块创建一个简单的HTML模板。首先我们要创建如下文件
app/design/frontend/default/default/layout/local.xml
包含以下内容
<?xml version="1.0" encoding="UTF-8"?>
<layout version="0.1.0">
??? <helloworld_index_index>
??????? <reference name="root">
??????????? <block type="page/html" name="root" output="toHtml" template="helloworld/simple_page.phtml"/>
??????? </reference>
??? </helloworld_index_index>
</layout>
再创建如下文件
app/design/frontend/default/default/template/helloworld/simple_page.phtml
包含以下内容
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
??????? "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
??? <title>Untitled</title>
??? <style type="text/css">
??????? body {
??????????? background-color:#f00;
??????? }
??? </style>
</head>
<body>
<h4>Links</h4>
<?php echo $this->getChildHtml('top.links'); ?>
<?php echo $this->getChildHtml('customer_form_register'); ?>
</body>
</html>
最后，我们要在执行控制器里面调用布局文件，开始输出HTML。修改执行方法如下
public function indexAction() {
??? //remove our previous echo
??? //echo 'Hello Index!';
??? $this->loadLayout();
??? $this->renderLayout();
}
