建立一個基本的 index 檔案
From Joomla! Documentation
index.php file becomes the core of every page that Joomla! delivers. Essentially, you make a page (like any HTML page) but place PHP code where the content of your site should go. The template works by adding Joomla code into module positions and the component section in your template. Anything added to the template will appear on all pages unless it is added to one of these sections via the Joomla CMS (or customised code).
This page will show the bare-bones code ready for you to cut and paste into your own design.
A Joomla template begins with the following lines:
<?php defined( '_JEXEC' ) or die( 'Restricted access' );?> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="<?php echo $this->language; ?>" lang="<?php echo $this->language; ?>" >
The first line stops naughty people looking at your coding and getting up to bad things.
The second line is the Document Type Declaration (DOCTYPE), which tells the browser (and web crawlers) which flavor of HTML the page is using. The doctype used above is HTML5, a newer version of HTML that is largely backwards compatible, but contains many new features. You should be aware that this will not work well in Internet Explorer 8 or earlier without a hack. You might want to investigate this situation and your clients' wishes before deciding on which doctype you want to use. However this is used in Joomla and higher.
The third line begins our HTML document and describes what language the website is in. A html document is divided into two parts, head and body. The head will contain the information about the document and the body will contain the website code which controls the layout.
<head> <jdoc:include type="head" /> <link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/system/css/system.css" type="text/css" /> <link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/system/css/general.css" type="text/css" /> <link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/<?php echo $this->template; ?>/css/template.css" type="text/css" /> </head>
template.css and is located in the
css folder of your template directory. So if your template is in
http://www.mysite.com/templates/my_template/ then the css files will go in
<body> <jdoc:include type="modules" name="top" /> <jdoc:include type="component" /> <jdoc:include type="modules" name="bottom" /> </body>
Amazingly, this will suffice! Yes, it's a very basic layout, but it will do the job. Everything else will be done by Joomla!. These lines, usually called jdoc statements, tell Joomla to include output from certain parts of the Joomla system. Note: you will need to ensure your menu is set to go into the "top" module position.
Above, the line which says
name="top" adds a module position called top and allows Joomla to place modules into this section of the template. The
type="component" line contains all articles and main content (actually, the component) and is very important. It goes in the centre of the template.
Note: You can add your own module lines anywhere you want in the body, but you have to add a corresponding line to the templateDetails.xml file which sits alongside the index.php of your template.
Finish it off - one last bit:
If you want to add any images to the template you can do so like this:
<img src="<?php echo $this->baseurl; ?>/templates/<?php echo $this->template; ?>/images/myimage.png" alt="Custom image" class="customImage" />
Here the template variable will fill in the name of your template.
<link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/<?php echo $this->template;?>/css/styles.css" type="text/css" />
Every file which is added must have a line in the templateDetails.xml file for the template, unless it resides in a sub-folder (which can be included in a <folder> element).
