    <p>I have two different but related tables and I want to be able to edit/update the information that is retrieved and displayed in a Form. In plain english here's what I am trying to achieve:</p> <p>SELECT colum_1, colum_2, colum_3 FROM table requests WHERE request_id = {$id}</p> <p>But at the same time, I want to: </p> <p>SELECT colum_A, colum_B, colum_C FROM table serialNumbers WHERE request_id = {$id}</p> <p>What's the correct/best way to do this all at once?</p> <p>Question Update: I have two files (1)my_request.php (which lists the details from the table requests), and (2) configuration.php (which is the form I will use to edit/update both table - mainly the serial numbers table). How do I pass on the id from my_request.php to the configuration.php... so that I can apply the instruction you provided above</p> <p>For my_request.php I have the following code. I am able to see all the requests created by the logged in user:</p> <pre><code>while ($row = mysql_fetch_assoc($results)) { $orderdate = strtotime($row['sl_date']); $fdate = strftime("%d/%m/%Y", $orderdate); echo '&lt;tr&gt;'; echo '&lt;td class="txtLeft"&gt;' . $row['request_date'] . '&lt;/td&gt;'; echo '&lt;td class="txtLeft"&gt;' . $row['client_name'] . '&lt;/td&gt;'; echo '&lt;td class="txtCenter"&gt;' . $row['client_country'] . '&lt;/td&gt;'; echo '&lt;td class="txtCenter"&gt;' . $row['opportunity_number'] . '&lt;/td&gt;'; echo '&lt;td class="txtCenter"&gt;' . $row['machine_quantity'] . '&lt;/td&gt;'; echo '&lt;td class="txtCenter"&gt;' . $row['severity'] . '&lt;/td&gt;'; echo '&lt;td class="txtCenter"&gt;' . $row['request_status']; echo '&lt;/td&gt;'; echo '&lt;td class="txtCenter" id="task1"&gt; &lt;a href="configuraion.php?request_id=' . $row['request_id'] . '"&gt; &lt;img src="images/edit.png" width="16" height="16" title="edit sale" style="margin:1px;"/&gt; &lt;/a&gt; &lt;a href="' . $row['sales_connect'] . '" onClick="return confirm(\''. $LANG['alert_sale_del'] .'\');"&gt; &lt;img src="images/s.png" width="16" height="16" title="Sales Connect" style="margin:1px;"/&gt; &lt;/a&gt; &lt;/td&gt;'; echo '&lt;/tr&gt;'; </code></pre> <p>What do I need to do on configuration.php so it understands which id to retrieve the info from? For the configuration.php I basically have the html form where I want to display the data.</p>

    3. COThere is only one record for the request, but on most cases there will be more than on Serial Number associated with one request. @ysth

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.
