Split Page into Specific Joomla! Versions - J2.5 and 3.x

Joomla! 使用 templates/system/error.php 檔案來管理各種 HTTP 狀態錯誤，包含 "403 Forbidden"、"404 Not Found"、以及 "500 Internal Server" 錯誤。如果想要的話，您可以改變錯誤訊息的樣式。

It is important to understand that error.php is an independent file from the Joomla! CMS but dependent on the Joomla! Platform. Plugins do not run on the file. You cannot include modules or use <jdoc:include> statements.

要覆寫系統錯誤結果

要覆寫系統錯誤結果，可以複製 templates/system/error.php 檔案到您的 templates/<template-name> 路徑。

If it finds one, Joomla! will use the error.php file from the current template, in place of the system file.

You can format the page, as desired, to match your template.

Overriding the System Styling

If you want to change the styling, copy the templates/system/css/error.css file into your templates/<template-name>/css directory. Next, update your templates/<template-name>/error.php file to reference the new location of the stylesheet by changing this line, accordingly:

<link rel="stylesheet" href="<?php echo $this->baseurl; ?>/templates/system/css/error.css" type="text/css" />

Then, simply change the error.css, as desired, for your styling requirements.

Customizing Error Messages

You can add conditional logic to vary the message returned, dependent upon the specific error code.

Here is an example of how to trap a 404 error and provide a custom message.

<?php  if ($this->error->getCode() == '404') { ?>
	<div id="errorboxheader">Page not found</div>
		<div id="errorboxbody"><p>Sorry! That page cannot be found.</p>
		</div>
	</div>
<?php } ?>

HTTP Status Code

When a request is made for a page on your site, the server returns an HTTP status code in response to the request. Joomla! returns a '200 - the server successfully returned the page' for error pages. This is problematic for those working with Google Webmaster Services and trying to get a sitemap resolved.

If you want Joomla! to return a status code for the error, you can do so by adding logic before the DOCTYPE line, as follows:

<?php 
if ($this->error->getCode() == '404') {
	header("HTTP/1.0 404 Not Found");
} ?>

在標準錯誤頁面使用主題頁首頁尾

If you want to see the error page in theme design and don't like redirecting to error page URL or duplicating HTML in the error page template, here is a way to apply your theme template to the error page.

First, put the following code in templates/<template-name>/error.php:

<?php
// no direct access
defined( '_JEXEC' ) or die( 'Restricted access' );

include dirname(__FILE__) . "/index.php";
?>

Then make the following edits to templates/<template-name>/index.php:

1. 在 index.php 找到以下的程式碼

<jdoc:include type="head" />

替換為以下的內容

<?php if (!$this->error->getCode()) : ?>
<jdoc:include type="head" />
<?php else : ?> 
<title><?php echo $this->error->getCode() ?> - <?php echo $this->title; ?></title>
<?php endif; ?>

2. 在 index.php找到以下的程式碼

<jdoc:include type="component" />

替換為以下的內容

<?php if ($this->error->getCode()) : /* check if we are on error page, if yes - display error message */ ?>
  <p><strong><?php echo $this->error->getCode() ?> - <?php echo $this->error->message ?></strong></p>
  <p><strong><?php echo JText::_('JERROR_LAYOUT_NOT_ABLE_TO_VISIT'); ?></strong></p>
  <ol>
    <li><?php echo JText::_('JERROR_LAYOUT_AN_OUT_OF_DATE_BOOKMARK_FAVOURITE'); ?></li>
    <li><?php echo JText::_('JERROR_LAYOUT_SEARCH_ENGINE_OUT_OF_DATE_LISTING'); ?></li>
    <li><?php echo JText::_('JERROR_LAYOUT_MIS_TYPED_ADDRESS'); ?></li>
    <li><?php echo JText::_('JERROR_LAYOUT_YOU_HAVE_NO_ACCESS_TO_THIS_PAGE'); ?></li>
    <li><?php echo JText::_('JERROR_LAYOUT_REQUESTED_RESOURCE_WAS_NOT_FOUND'); ?></li>
    <li><?php echo JText::_('JERROR_LAYOUT_ERROR_HAS_OCCURRED_WHILE_PROCESSING_YOUR_REQUEST'); ?></li>
  </ol>
  <p><strong><?php echo JText::_('JERROR_LAYOUT_PLEASE_TRY_ONE_OF_THE_FOLLOWING_PAGES'); ?></strong></p>

  <ul>
  <li><a href="<?php echo $this->baseurl; ?>/index.php" title="<?php echo JText::_('JERROR_LAYOUT_GO_TO_THE_HOME_PAGE'); ?>"><?php echo JText::_('JERROR_LAYOUT_HOME_PAGE'); ?></a></li>
  </ul>

  <p><?php echo JText::_('JERROR_LAYOUT_PLEASE_CONTACT_THE_SYSTEM_ADMINISTRATOR'); ?>.</p>
<?php else : ?>
  <jdoc:include type="component" />
<?php endif; ?>

現在您的佈景主題會被套用在錯誤訊息頁面

注意： 這個方法建立的錯誤訊息頁面，會讓佈景主題規劃的模組無法作用(但會在其他頁面上作用)。

在錯誤頁面中使用模組

同樣地，不像佈景主題index.php，因為您不能使用 <jdoc:include> 聲明，在錯誤訊息頁面中，不能使用佈景主題規劃的模組。您可以使用 JModuleHelper。

要依據標題 include 單一模組，您可以使用：

if (JModuleHelper::getModule('menu')) { 
    echo $doc->getBuffer('module', 'menu');
}

要依據位置 include 多個模組，您可以使用：

$modules = JModuleHelper::getModules( 'footer_3' );
$attribs['style'] = 'xhtml';
foreach ($modules AS $module ) {
    echo JModuleHelper::renderModule( $module, $attribs );
}
