mysql查询没有正确格式化

Question

我对此非常接近，但仍然遇到事件列表问题。我正在寻找的是标题，日期和事件，以及参加该事件的名单列表。现在我得到的事件，日期和标题打印的次数与名称相同，每个都只显示一个名称。

我在几个领域尝试过GROUP BY，但似乎没什么用。

current

这就是我现在所得到的：undesired

这就是我想要的：desired

Answer 1

我可能做的是让一个变量表示“此行中的数据是否与新事件相对应，还是同一事件的附加数据？”

如果日期不匹配，那就是新事件;首先，添加一个新的标题行，然后添加一个包含所有四列数据的新行。如果日期匹配，则跳过标题并添加一行，前三列为空，第四列为新名称。 （抱歉，如果我的PHP没有完全编译，那已经有一段时间了。）

另外，我不确定你真正想要的是单独的表格;如果是这样，那么在第一个$lastEventDate = ''; Print "<table width=500>"; while($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']; } 块内，您可以关闭第一个表，然后打开一个新表。
