    <p>I'm developing a PHP website that uses url routing. I'd like the site to be directory independent, so that it could be moved from <a href="http://site.example.com/" rel="noreferrer">http://site.example.com/</a> to <a href="http://example.com/site/" rel="noreferrer">http://example.com/site/</a> without having to change every path in the HTML. The problem comes up when I'm linking to files which are not subject to routing, like css files, images and so on. </p> <p>For example, let's assume that the view for the action <code>index</code> of the controller <code>welcome</code> contains the image <code>img/banner.jpg</code>. If the page is requested with the url <a href="http://site.example.com/welcome" rel="noreferrer">http://site.example.com/welcome</a>, the browser will request the image as <a href="http://site.example.com/img/banner.jpg" rel="noreferrer">http://site.example.com/img/banner.jpg</a>, which is perfectly fine. But if the page is requested with the url <a href="http://site.example.com/welcome/index" rel="noreferrer">http://site.example.com/welcome/index</a>, the browser will think that <code>welcome</code> is a directory and will try to fetch the image as <a href="http://site.example.com/welcome/img/banner.jpg" rel="noreferrer">http://site.example.com/welcome/img/banner.jpg</a>, which is obviously wrong.</p> <p>I've already considered some options, but they all seem imperfect to me:</p> <ul> <li><p>Use url rewriting to redirect requests from (<strong>*.css</strong>|<strong>*.js</strong>|...) or (<strong>css/*</strong>|<strong>js/*</strong>|...) to the right path. </p> <p><em>Problems</em>: Every extension would have to be named in the rewrite rules. If someone would add a new filetype (e.g. an mp3 file), it wouldn't be rewritten.</p></li> <li><p>Prepend the base path to each relative path with a php function. For example:<br> <code>&lt;img src="&lt;?php echo url::base(); ?&gt;img/banner.jpg" /&gt;</code> </p> <p><em>Problems</em>: Looks messy; <strong>css</strong>- and <strong>js</strong>-files containing paths would have to be processed by PHP.</p></li> </ul> <p>So, how do you keep a website directory independent? Is there a better/cleaner way than the ones I came up with?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
