If you are trying to generate lots of form each with just a button then you need to put the form in a table cell like this
It might also be useful to place the data items you want to pass in hidden fields rather than try and put 2 data items in the button value
<?php
$propertyType = $xmlDom1->getElementsByTagName('PropertyType');
$rent = $xmlDom1->getElementsByTagName('rates');
$rooms = $xmlDom1->getElementsByTagName('rooms');
//$server = $xmlDom1->getElementsByTagName('server');
$propertyServer = $xmlDom1->getElementsByTagName('Property');
$propertyID = $xmlDom1->getElementsByTagName('Property');
$imageURL = $xmlDom1->getElementsByTagName('url');
$imageAlt = $xmlDom1->getElementsByTagName('altText');
$server = $propertyID->item($i)->getAttribute('server');
echo '<table><th>Type:</th><th>Rent:</th><th>Rooms:</th><th>Server</th>';
$records = $xmlDom1->documentElement->childNodes;
for ($i = 0; $i < $records->length; $i++) {
echo "<tr><td>".$propertyType->item($i)->nodeValue."</td>";
echo "<td>".$rent->item($i)->nodeValue."</td>";
echo "<td>".$rooms->item($i)->nodeValue."</td>";
echo "<td>".$propertyServer->item($i)->getAttribute('Server')."</td>";
echo '<td><img src="data:image/jpeg;base64,'.$imageURL->item($i)->nodeValue.'" alt="'.$imageAlt->item($i)->nodeValue.'"></img></td>';
$pid = $propertyID->item($i)->getAttribute('pid');
?>
<td>
<form action="level5Details.php" method="get" enctype="application/x-www-form-urlencoded">
<input type="hidden" name="pid" value="<?php echo $pid;?>">
<input type="hidden" name="server" value="<?php echo $server;?>">
<button class="submit" type="submit" value="submit" name="submit22">something</button>
</form>
</td>
</tr>
<?php
}
?>
If you just want the button to carry all the data and have only one form you will have to package the 2 data items into one string and sent it as the value of the button
<?php
$propertyType = $xmlDom1->getElementsByTagName('PropertyType');
$rent = $xmlDom1->getElementsByTagName('rates');
$rooms = $xmlDom1->getElementsByTagName('rooms');
//$server = $xmlDom1->getElementsByTagName('server');
$propertyServer = $xmlDom1->getElementsByTagName('Property');
$propertyID = $xmlDom1->getElementsByTagName('Property');
$imageURL = $xmlDom1->getElementsByTagName('url');
$imageAlt = $xmlDom1->getElementsByTagName('altText');
$server = $propertyID->item($i)->getAttribute('server');
echo '<form action="level5Details.php" method="get" enctype="application/x-www-form-urlencoded">';
echo '<table><th>Type:</th><th>Rent:</th><th>Rooms:</th><th>Server</th>';
$records = $xmlDom1->documentElement->childNodes;
for ($i = 0; $i < $records->length; $i++) {
echo "<tr><td>".$propertyType->item($i)->nodeValue."</td>";
echo "<td>".$rent->item($i)->nodeValue."</td>";
echo "<td>".$rooms->item($i)->nodeValue."</td>";
echo "<td>".$propertyServer->item($i)->getAttribute('Server')."</td>";
echo '<td><img src="data:image/jpeg;base64,'.$imageURL->item($i)->nodeValue.'" alt="'.$imageAlt->item($i)->nodeValue.'"></img></td>';
$dataPackage = $propertyID->item($i)->getAttribute('pid') . ':' . $server;
?>
<td>
<button class="submit" type="submit" value="<?php echo $dataPackage;?>" name="submit22">something</button>
</td>
</tr>
<?php
}
</table>
</form>
?>
Now in the receiving form unpack the data for use
<?php
// usual checks for things existing
list($pid, $server) = explode(':', $_GET['submit22'];
