Display wrong information with the good row value - php

Question

I have a problem with the code below. In fact, it's supposed to show the information of a table, where the MomentEvent value match with the row requested. The only problem, is that sometimes, it show the information of a complete diffrent row! And I don't have any idea why! Does the problem come from my code?
And in my table, the information are placed in order, so they are always added one after an other.
<?php
include('base.php');
?>
<?php
if(isset($_GET['MomentEvent']))
{
$MomentEvent = intval($_GET['MomentEvent']);
$dn = mysql_query("select Ordre, Confidentialite, ID, TitreEvent, DescriptionEvent, LieuEvent from users_event where MomentEvent=$MomentEvent");
if(mysql_num_rows($dn)>0)
{
$dnn = mysql_fetch_array($dn);
?>
This is the profile of "<?php echo htmlentities($dnn['TitreEvent']); ?>" :
<table style="width:500px;">
<tr><td>
<?php
if($dnn['avatar']!='')
{
echo '<img src="'.htmlentities($dnn['avatar'], ENT_QUOTES, 'UTF-8').'" alt="Avatar" style="max-width:100px;max-height:100px;" />';
}
else
{
echo 'This user dont have an avatar.';
}
?>
</td>
<td class="left"><h1><?php echo ($dnn['TitreEvent']); ?></h1>
Email: <?php echo htmlentities($dnn['DescriptionEvent']); ?><br />
<a href=*****.php>Retour.</a>
</tr>
</table>
<?php
}
else
{
echo 'Sorry, any event found';
}
}
else
{
echo 'The user ID is not defined.';
}
?>
</body>
</html>

Answer 1

you have missed </td> in your code.
and use echo $dnn['TitreEvent']; without parenthesis
try this
<td class="left"><h1><?php echo $dnn['TitreEvent']; ?></h1>
Email: <?php echo htmlentities($dnn['DescriptionEvent']); ?><br />
<a href=*****.php>Retour.</a>
</td>
^^----you missed this
EDIT:
Ithink you have many result returned from your sql and you need to specify more in your query .
like that
where MomentEvent=$MomentEvent AND user = $theUser

Answer 2

Now all works fine with these changes:
$MomentEvent = $_GET['MomentEvent'];
$sql = "select ID, TitreEvent, DescriptionEvent, LieuEvent from users_event where MomentEvent='$MomentEvent'";
$dn = mysql_query($sql);
