Displaying distinct columns and non-distinct column in one table
I have 3 tables. One is userinfo (which where you can find Name), then logs for login details and evaluation for user evaluation of the activity. They are connected by the field attendee_id.
When I joined them it gives me this output:
What I want is to have an output like this:
When I use GROUP BY Name it returned only one row for each and not returning other data.

Answer 1

It can be done like this. In this example I have hard coded the $rows array, but you can replace that with your array of rows from the database.
<?php
$rows = array(
array(
'name' => 'Juan',
'login' => '09:00:01',
'evaluation' => 'Yes'
),
array(
'name' => 'Juan',
'login' => '09:00:02',
'evaluation' => 'Yes'
),
array(
'name' => 'Juan',
'login' => '09:00:03',
'evaluation' => 'Yes'
),
array(
'name' => 'Jose',
'login' => '09:00:04',
'evaluation' => 'No'
),
array(
'name' => 'Jose',
'login' => '09:00:05',
'evaluation' => 'No'
)
);
?>
<table>
<tr>
<th>Name</th>
<th>Login</th>
<th>Evaluation</th>
</tr>
<?php
$prevName = '';
foreach($rows as $row):
if($prevName == $row['name']) {
$name = '';
} else {
$name = $prevName = $row['name'];
}
?>
<tr>
<td><?php echo htmlspecialchars($name); ?></td>
<td><?php echo htmlspecialchars($row['login']); ?></td>
<td><?php echo htmlspecialchars($row['evaluation']); ?></td>
</tr>
<?php endforeach; ?>
</table>
The result is:

Answer 2

I tried doing this a few times and gave up. In the end, I formatted the output in PHP by checking if the value for 'name' in the current row is different to the previous one:
<?php
//Assume the query has been done
//...
$lastName='';
echo '<table>';
while ($row=mysql_fetch_assoc($query_result))
{
if ($row['name']!=$lastName)
{
$lastName=$row['name'];
} else
{
$row['name']='';
}
echo '<td>'.implode('</td><td>',$row).'</td>;
echo '<tr>';
}
echo '</table>';
It's not pretty but it'll get you the result you want. You can tart it up by
