    <p>I have a bunch of dom manipulation functions within a class. One of those functions assigns unique ids to specific nodes.</p> <pre><code>$resource_info_node-&gt;setAttribute('id', 'resource_'.$this-&gt;ids); $details['id'] = 'resource_'.$this-&gt;ids; $details['node'] = $resource_info_node; $this-&gt;resource_nodes['resource_'.$this-&gt;ids] = $details; $this-&gt;ids += 1; </code></pre> <p>later I want to look up and modify those nodes. I have tried :</p> <pre><code>$current_node = $this-&gt;resource_nodes[$id]['node']; </code></pre> <p>When I print_r() I find that this node is a duplicate of the original node. It has the original node's attributes but is not a part of the DOM tree. I get the same results with :</p> <pre><code>$this-&gt;content-&gt;getElementById($id); </code></pre> <p>I suppose I based this whole thing on storing node references in an array. I thought that was a fine thing to do. Even if not, after that using getElementByID() should have returned the node within the dom.</p> <p>I thought that, in PHP all objects were passed by reference. Including DOM nodes. Any ideas on how I can test what is actually going on.</p> <p><strong>EDIT :</strong> </p> <p>Well I used :</p> <pre><code>$this-&gt;xpath-&gt;query('//*[@id]'); </code></pre> <p>That returned the right number of items with ids. The node is just not in the DOM tree when I edit it.</p> <p>and </p> <pre><code>$current_node = &amp;$this-&gt;resource_nodes[$id]['node']; </code></pre> <p>Using the reference syntax had no affect.</p> <p>The strangest part is that get elementById() is not returning a node in the dom. It has all the right attributes except no parentNode.</p> <p><strong>FIX - not answer :</strong> </p> <p>I just used xpath instead of my reference or getElementById().</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.
