    <p>I'm trying to get a value to be inserted into a table on a webpage if the value equals $i.</p> <p>$i starts at a number and decreases every loop. i can get it to work but it outputs multiple lines for each $i equivalent to the results in the table</p> <p>I've reworked the code using everyones feedback to get this.</p> <pre><code>Echo "&lt;tr&gt;&lt;th colspan='3'&gt;&lt;center&gt;$rackname&lt;/th&gt; &lt;/tr&gt;" ; for ($i=$RUtotal; $i &gt; 0; $i--) { echo" &lt;tr class='rackbg'&gt;&lt;td class='i'&gt;&lt;center&gt;$i&lt;/td&gt;" ; $sql1 = "SELECT racks.rackID, racks.rackname, devices.deviceID, devices.deviceName, racks.rackRU, devices.deviceRU, devices.RUcount FROM racks LEFT JOIN devices ON racks.rackID = devices.rackID WHERE devices.rackID = '$rackID'"; $query1 = mysql_query($sql1); while ($row = mysql_fetch_assoc($query1)) { $deviceru = $row['deviceRU']; $deviceID = $row['deviceID']; $device = $row['deviceName']; $deviceRUC = $row['RUcount']; if ($deviceru == $i) { echo '&lt;td class="device" rowspan='.$deviceRUC.'&gt;&lt;a onclick=window.location="/devices.php?id='.$deviceID.'"&gt;'.$device.'&lt;/a&gt;&lt;/td&gt;&lt;td rowspan='.$deviceRUC.'&gt;&lt;/td&gt;&lt;/tr&gt;'; } else { ; } } } Echo "&lt;tr class='rackb'&gt;&lt;th colspan='3'&gt;a&lt;/th&gt;&lt;/tr&gt; " ; </code></pre> <p>This works to a degree (picture1) but when i add echo "" to the else statement it displays all wrong. (picture 2)</p> <p>Any help would be greatly appreciated</p> <p>Picture1 - <a href="http://imageshack.us/photo/my-images/263/examplewq.png/" rel="nofollow">http://imageshack.us/photo/my-images/263/examplewq.png/</a></p> <p>Picture2 - <a href="http://imageshack.us/photo/my-images/269/example2jp.png/" rel="nofollow">http://imageshack.us/photo/my-images/269/example2jp.png/</a></p>

    1. COCan you do a var_dump($row); inside of this loop to see what $row looks like? That might provide some more insight for me.

    2. COAlso, open up a util like SQuirrelSQL to check out the table. No dupe data?

    3. COI don't see why the you are using the outer loop the way you are. The variable $i has no effect on the query, so you are effectively running the same query over and over.

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).
