记录多于一条时，记录将显示两次

Question

我正在使用CodeIgniter，正在显示数据库中的数据。

我正在视图上显示数据（预期输出）

第1行

AFGFD ANAND
trdsd@gmail.com

ActivityName   | Activity_startTime | Activity_endTime
cricket        | 05:00.             | 08:00

---

第2行

POIUY ANAND
mnbsd@gmail.com

ActivityName   | Activity_startTime | Activity_endTime
cricket        | 05:00.             | 08:00
Badminton      | 09:00.             | 11:00

问题是，第一行显示得很完美，因为我只有一个活动，但是第二行却获得了多个记录。

我正在获得第二行的输出，例如

POIUY ANAND
mnbsd@gmail.com

POIUY ANAND
mnbsd@gmail.com

ActivityName   | Activity_startTime | Activity_endTime
cricket        | 05:00.             | 08:00
ActivityName   | Activity_startTime | Activity_endTime
Badminton      | 09:00.             | 11:00

如何分别显示个人信息和活动信息？

我知道我使用了2 foreach，这就是我得到输出的原因。我想我可以通过更改模型查询来显示个人信息和活动信息。

查看代码

foreach ($SActivity as $sec_data) {
    foreach ($sec_data as $row) { ?>
        <h2><?php echo $row->first_name;?><?php echo $row->last_name;?></h2>
        <p><?php echo $row->email;?></p>
        <table>
            <thead>
                <tr>
                    <th>ActivityName</th>
                    <th>Activity_startTime</th>
                    <th>Activity_endTime</th>
                </tr>
            </thead>
            <tbody>
                <tr>
                    <td><?php echo $row->ActivityName;?></td>
                    <td><?php echo $row->Activity_startTime;?></td>
                    <td><?php echo $row->Activity_endTime;?></td>
                </tr>
            </tbody>
        </table>
<?php }
} 

我在视图页面中得到输出

模型

public function getSecondaryMemberActivity($gotMemberId)

    $getDetails = ['members.member_id' => $gotMemberId];
    $result = $this->db->where($getDetails)
        ->from('members')

    if($result) {

    } else  {
        return 0;    
    }
}

您能在这个问题上帮助我吗？

在您的视图中尝试此代码。我只添加了一个计数器来跟踪每个用户的活动数量，并跟踪循环中的当前位置，以便仅打印出每个用户的一个表头和用户信息：

<?php 
foreach ($SActivity as $sec_data) {

    $counter = 0; // COUNTER FOR KNOWING POSITION IN ACTIVITIES LOOP 
    $num_activities = count($sec_data); // TOTAL NUMBER OF ACTIVITIES FOR THIS USER

    foreach ($sec_data as $row) { 
        $counter++; // ADD +1 TO COUNTER FOR EACH ACTIVITY

        // ONLY PRINT OUT THE NAME AND TABLE HEADER IF FIRST ROW 
        if($counter == 1){ ?>

        <h2><?php echo $row->first_name;?><?php echo $row->last_name;?></h2>
        <p><?php echo $row->email;?></p>
        <table>
            <thead>
                <tr>
                    <th>ActivityName</th>
                    <th>Activity_startTime</th>
                    <th>Activity_endTime</th>
                </tr>
            </thead>
            <tbody>

        <?php } ?>      

                <tr>
                    <td><?php echo $row->ActivityName;?></td>
                    <td><?php echo $row->Activity_startTime;?></td>
                    <td><?php echo $row->Activity_endTime;?></td>
                </tr>

        <?php 
        // IF THIS IS THE LAST ACTIVITY OF THIS USER IN THE LOOP: PRINT TABLE END TAG
        if($counter == $num_activities){
            echo '</tbody></table>';
        }
    } 
} 
?>
