    <p>If you have an item where you allow users to add comments, how can you pass which item the user is replying too?</p> <p>I've though of using a hidden field in a form, however this can be easily changed using plugins such as firebug:</p> <pre><code>&lt;form method="post" action="blah"&gt; &lt;input type="hidden" name="item_id" value="&lt;?php echo $item_id; ?&gt;"&gt; &lt;!-- other form data here --&gt; &lt;input type="submit" name="submit"&gt; &lt;/form&gt; </code></pre> <p>Or just simply using a session:</p> <pre><code>$_SESSION['item_id'] = $item_id </code></pre> <p>Is there a safe way to send the item data in a form?</p> <p><strong>Edit:</strong> This is <em>after</em> validation,... I do implement some XSS protection (form tokens etc). The reason I was asking was just to know what the best practise is.</p> <p>I though of doing something like </p> <pre><code>$_SESSION['item_id'] = $id //this is set when they visit the current item </code></pre> <p>then in the form have a hidden field:</p> <pre><code>&lt;input type="hidden" name="item_id" value="&lt;?php echo $id?&gt;"&gt; </code></pre> <p>Finally check the session matches the id clicked:</p> <pre><code>if ($_SESSION('item_id') !== $item_id) //the value posted in the form { die('There\'s got to be a morning after If we can hold on through the night We have a chance to find the sunshine Let\'s keep on looking for the light'); } </code></pre> <p>However after reading some of your comments I guess this is a bad idea?</p> <p>To be fair (@Surreal Dreams): it isn't that big a deal if they do change the id, I as I've said,I was just looking for the best practice.</p> <p>Cheers.</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.
