New breadcrumbs tag

[rickb]

I like to have clean separation of presentation from content.  The existing breadcrumb tag doesn't do this; instead it builds the presentation stuff into the HTML. So I wrote a new version of it (which I imaginatively called breadcrumbs2) that generates a sequence of list elements.  You just wrap it in a of your own choosing and write some CSS to make it look nice.

Most of the optional attributes were not strictly needed, so I simplified it by removing them.

Here's the additional admin text.

Code: Select all

$lang['admin']['about_function_breadcrumbs2'] = <<<EOT

<p>Version: 1.0</p>

Change History:<br/>
</p>
EOT;

$lang['admin']['help_function_breadcrumbs2'] = <<<EOT
<h3>What does this do?</h3>
<p>Prints a breadcrumb trail as a navigation list.</p>
<h3>How do I use it?</h3>
<p>Just insert the tag into your template/page within a list like this:
<code><ul class="breadcrumb_trail">{breadcrumbs2}</ul></code>. The markup is designed to be easy to
decorate using CSS. Your CSS might draw from some ideas here:</p>
<pre>
div.navigation ul.breadcrumb_trail li {
    display: inline;
    list-style: none;
    font-size: 11px;
}
div.navigation ul.breadcrumb_trail li.parent {
    padding: 0 20px 0 0;
    background: url(/css/images/tab_right.png) right no-repeat;
}
div.navigation ul.breadcrumb_trail li.last {
    font-weight: bold;
    color: #555;
}
</pre>
<h3>What parameters does it take?</h3>
<p>
<ul>
<li><em>(optional)</em> <tt>root</tt> - Page alias of a page you want to always appear as the first page in
    the list. Can be used to make a page (e.g. the front page) appear to be the root of everything even though it is not.</li>
<li><em>(optional)</em> <tt>root_url</tt> - Override the URL of the root page. Useful for making link be to '/' instead of '/home/'. This requires that the root page be set as the default page.</li>
</ul>
</p>
