    <p>I wonder whether someone may be able to help me please.</p> <p>I'm using the script below to create a 'gallery' page. </p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;?php //This variable specifies relative path to the folder, where the gallery with uploaded files is located. $galleryPath = 'UploadedFiles/'; $thumbnailsPath = $galleryPath .

&lt;/files&gt; </code></pre> <p>What I wanted to do is filter the records returned, to be more specific by 'userid' and 'locationid' and for testing purposes these had the value of '1'.</p> <p>I'd received some useful guidance from this site at <a href="https://stackoverflow.com/questions/9749774/xml-select-where-statement">XML &#39;Select Where&#39; Statement</a>, and from the subsequent 'XPath' tutorials I've read I put together what I thought would be the correct xpath code to use which is at the top of my 'gallery' page script.</p> <p>However, when I've tried to run this I recieve the following error:</p> <p><code>Parse error: syntax error, unexpected '=' in /homepages/2/d333603417/htdocs/development/gallery.php on line 16</code></p> <p>It's clear that the problem is with the 'equals', but when I've gone back to the tutorials, this appears to be the correct syntax to use.</p> <p>I just wondered whether someone could perhaps have a look at this please and let me know where I've gone wrong.</p> <p>Many thanks</p> <p><strong>Amended Xpath Code</strong></p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
