    <p>I am able to get the web path to the file like so:</p> <pre><code>$filename = 'elephant.jpg'; $path_to_file = $this-&gt;getSkinUrl('manufacturertab'); $full_path = $path_to_file . '/' . $filename; </code></pre> <p>But if the file doesn't exist, then I end up with a broken image link.</p> <p>I tried this:</p> <pre><code>if(!file_exists($full_path)) { Mage::log('File doesn\'t exist.'); } else { ?&gt;&lt;img src="&lt;?php echo $full_path ?&gt;" /&gt;&lt;?php } </code></pre> <p>Of course that didn't work because <code>file_exists</code> does not work on urls.</p> <p>How do I solve this?</p> <p>1.) Can I translate between system paths and web urls in Magento?</p> <p>e.g. something like (pseudocode):</p> <pre><code>$system_path = $this-&gt;getSystemPath('manufacturertab'); </code></pre> <p>That looks symmetrical and portable.</p> <p>or 2.) Is there some PHP or Magento function for checking remote resource existence? But that seems a waste, since the resource is really local. It would be stupid for PHP to use an http method to check a local file, wouldn't it be?</p> <p>Solution I am currently using:</p> <pre><code>$system_path = Mage::getBaseDir('skin') . '/frontend/default/mytheme/manufacturertab'; // portable, but not pretty $file_path = $system_path . '/' . $filename; </code></pre> <p>I then check if <code>file_exists</code> and if it does, I display the <code>img</code>. But I don't like the asymmetry between having to hard-code part of the path for the system path, and using a method for the url path. It would be nice to have a method for both.</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.
