【问题描述】：
我在组合框填充数据时遇到问题。
我有一个表 user 列：
- usrIndex
- usr昵称
- usrFullname
- usrEmail
我们正在绑定数据，包括与其他表的连接（如 hrh...），我们正在计算用户心率和他们的卡路里，使用以下代码：
$totalPoints = 0;
$totalDuration = 0;
$totalCalories = 0;
$noOfParticipants = 0;
$includedUsers = 0;
$participants = "";
主程序
$query = "SELECT DISTINCT usrIndex,usrNickname";
$query .= " FROM hrheader hrh";
$query .= " INNER JOIN `user` usr ON hrh.hrhUsrIndex=usr.usrIndex";
$query .= " WHERE usrSIndex=$sIndex";
$query .= " AND hrhStart>'" . $start . "' AND hrhStart<'" . date("Y-m-d", strtotime($end . " +1 days")) . "'";
$query .= " ORDER BY usrNickname";
$gresult = mysql_query($query);
if ($gresult)
{
$noOfParticipants = mysql_num_rows($gresult);
$participants = "<table style='text-align:center;font-size:18px;width:980px;margin- top:16px;color:#231f20;'>";
$participants .= "<tr>";
$participants .= "<th>Nickname</th><th>Time (Hours & Mins)</th><th>Average Effort</th><th>Calories</th><th><img src='../images/mepslogo.png' /></th>";
$participants .= "</tr>";
下面的代码和图表有助于清楚地理解问题：
while ($grow = mysql_fetch_array($gresult))
{
$query = "SELECT ROUND(AVG(hr/hrhMaxHR)*100) AS AverageEffort,ROUND(AVG(hr)) AS AverageHeartRate,ROUND(MAX(hr)) AS MaxHeartRate,";
$query .= " COUNT(DISTINCT hrhIndex) AS NumberOfMoves";
$query .= " FROM `hrheader` hrh INNER JOIN hr ON hrh.hrhIndex=hr.hrHrhIndex";
$query .= " WHERE hrhUsrIndex=" . $grow['usrIndex'] . " AND hr>0";
$query .= " AND hrReceivedTime>'" . $start . "' AND hrReceivedTime<'" . date("Y-m-d", strtotime($end . " +1 days")) . "'";
$result = mysql_query($query);
$pAverageEffort = 0;
$pAverageHeartRate = 0;
$pMaxHeartRate = 0;
$pNumberOfMoves = 0;
if ($result)
{
$row = mysql_fetch_array($result);
if ($row)
{
$pAverageEffort = $row['AverageEffort'] . "%";
$pAverageHeartRate = $row['AverageHeartRate'];
$pMaxHeartRate = $row['MaxHeartRate'];
$pNumberOfMoves = $row['NumberOfMoves'];
}
}
$query = "SELECT hr,hrReceivedTime,hrhMaxHR,hrhWeight,FLOOR(DATEDIFF(hrReceivedTime,usrDOB)/365) AS Age,usrGender";
$query .= " FROM hrheader hrh INNER JOIN hr ON hrh.hrhIndex=hr.hrHrhIndex";
$query .= " INNER JOIN `user` usr ON hrh.hrhUsrIndex=usr.usrIndex";
$query .= " WHERE hrhUsrIndex=" . $grow['usrIndex'] . " AND hr>0";
$query .= " AND hrReceivedTime>'" . $start . "' AND hrReceivedTime<'" . date("Y-m-d", strtotime($end . " +1 days")) . "'";
$query .= " ORDER BY hrReceivedTime";
//echo $query;
$result = mysql_query($query);
$lastReceived = false;

{

}
$count++;
$pDuration += $t;
$pCalories += calculateCalPerMin($row['hr'], $row['hrhWeight'], $row['Age'], $row['usrGender']) * $t;
}

$zone1 = floor($zone1);

}

$participants .= "</table>";
这是主程序的html代码（这里我们定义了html表）：
<div class="txt" style="margin-right:10px;margin-top:16px;font-size:18px;width:462px;float:right">
<div class="txtl"></div>
<div class="txtr"></div>
<span>% of group that achieved target</span>
<span id="spanPercentAchieved" style="color:black;float:right">-%</span>
</div>
<div class="txt" style="margin-left:10px;margin-top:16px;font-size:18px;width:462px">
<div class="txtl"></div>
<div class="txtr"></div>
<span>Number of users achieved target</span>
<span id="spanNumberAchieved" style="color:black;float:right">-</span>
</div>
<span id="spanParticipants">
<table style='text-align:center;font-size:18px;width:980px;margin-top:16px;color:#231f20;'>
<tr>
<th>Nickname</th>
<th>No of Sessions</th>
<th>Duration</th>
<th>Average Effort</th>
<th><img src='../images/mepslogo.png' /></th>
</tr>
</table>
</span>
我已在“主程序”中指明查询并将数据绑定到html表
这段代码可以正常工作......但我的问题是
我想在该组合框中的昵称标题处设置 html 表内的组合框，当用户选择这些选项（全名、电子邮件）时，选项类似于（昵称、全名、电子邮件），他们将能够看到用户的电子邮件并全名当前显示昵称的人..
我想要这样：
如果用户选择全名，将显示全名而不是昵称，当用户选择电子邮件ID时，将显示电子邮件ID而不是用户的昵称。
此组合框选择将在表格列标题中设置。
有人可以帮忙吗？
任何人都可以在这个...这个主题上提供帮助。
