mysql query not formatting correctly - php

Question

I am very close on this but still having a problem with the listing of events. What I am looking for is for the title, date and event to show once with a list of names who participated in that event. Now I am getting an event, date and title printed as many times as names, with only one name showing in each.
I have tried GROUP BY on several fields but nothing seems to work.
SELECT x.xdate, x.xevent, x.xname, x.xaffirm, y.activity, y.title,
y.text, y.date
FROM x LEFT JOIN y ON x.xdate = y.date
WHERE xevent='Hiking' AND xaffirm='Yes'
ORDER BY y.date DESC")
Print "<table width=500>";
while($info = mysql_fetch_array( $data ))
{
Print "<tr>";
Print
"<th style='width:225px;' bgcolor=#49A78D align=center >Title</th>
<th style='width:300px;' bgcolor=#49A78D align=center >Text</th>
<th style='width:175px;' bgcolor=#49A78D align=center >Date</th>
<th style='width:175px;' bgcolor=#49A78D align=center >Name</th>";
Print "</tr>";
Print "<tr>";
Print
"<td bgcolor=#ffffff valign=top align=center>".$info['title'] . "</td>
<td bgcolor=#ffffff valign=top align=left>".$info['text'] . "</td>
<td bgcolor=#ffffff valign=top align=left>".$info['date'] . "</td>
<td bgcolor=#ffffff valign=top align=left>".$info['name'] . "</td>";
Print "</tr>";
This is what I am getting now:undesired
This is what I would like to get: desired

What I'd probably do is to have a single variable that denotes "does the data in this row correspond to a new event, or is it additional data for the same event?"
If the date doesn't match, it's a new event; first, add a new header row, then add a new row with data for all four columns. If the date does match, then skip the header and add a row where the first three columns are empty and the fourth has the new name. (Apologies if my PHP doesn't quite compile, it's been a while.)
$lastEventDate = '';
Print "<table width=500>";
while($info = mysql_fetch_array( $data ))
{
if ($lastEventDate != $info['date'])
{
Print "<tr>";
Print
"<th style='width:225px;' bgcolor=#49A78D align=center >Title</th>
<th style='width:300px;' bgcolor=#49A78D align=center >Text</th>
<th style='width:175px;' bgcolor=#49A78D align=center >Date</th>
<th style='width:175px;' bgcolor=#49A78D align=center >Name</th>";
Print "</tr>";
}
Print "<tr>";
if ($lastEventDate == $info['date'])
{
Print "<td colspan=3 />"
}
else
{
Print
"<td bgcolor=#ffffff valign=top align=center>".$info['title'] . "</td>
<td bgcolor=#ffffff valign=top align=left>".$info['text'] . "</td>
<td bgcolor=#ffffff valign=top align=left>".$info['date'] . "</td>"
}
Print "<td bgcolor=#ffffff valign=top align=left>".$info['name'] . "</td>";
Print "</tr>";
$lastEventDate = $info['date'];
}
Also, I'm unsure whether what you actually want is separate tables; if so, then inside the first if block, you can close the first table, then open a new one.
