PHP的出勤门户

我在最终出勤报告生成中遇到问题

我被困在项目的最后阶段：

我有一个表出席者，如果一个学生在场，如果缺席，我将其标记为1。我们有日期，订单，小时（我们遵循的是订单日程安排表）

Table 
dayorder:
    id day
    1 day1
    2 day2
    3 day3
    4 day4
    5 day5
    6 SAT
    7 day6

Table 
Hour:
   id
    1
    2
    3
    4
    5
    6
    7

出席人数：

我必须生成一个月度报告，如下所示的注册表

PHPMYADMIN中的输出但是我无法使用PHP和MY SQL显示为HTML页面

Answer 1

我为您的情况写了一个PHP MySQL示例，但没有确切地了解您的SQL，为什么您首先还需要很多时间来描述。此外，您还必须花费数小时来添加代码，这只是PHP MySQL示例的正确方法，如果您不愿意发表评论，我建议您将ez_SQL与oho MySQL一起使用更好的对象编程

    <?php
    $sql="SELECT * FROM attendance ORDER BY student_id ASC, date ASC";
    $result = $conn->query($sql);
    if ($result->num_rows > 0) {
        // output data of each row
        echo "<table><thead><tr><td># Student ID</td><td>Dept No</td><td>Description</td>";
        for ($i=0; $i < $day; $i++) { 
            echo "<td>".$i."</td>";
        }
        echo "</tr></thead><body><tr>";

        while($row = $result->fetch_assoc()) {
            $student_id = $row->student_id;
            $deptno = $row->deptno;
            $decp = $row->date." ".$row->semester." ".$row->day;
            $absence = $row->present;
            if(isset($temp) and $temp != $student_id){
                echo "</tr>";
                echo "<tr>";
                echo "<td>".$student_id."</td><td>".$deptno."</td><td>".$decp."</td>"
            }elseif(!isset($temp)){
                echo "<td>".$student_id."</td><td>".$deptno."</td><td>".$decp."</td>";
            }

            echo "<td>".$absence."</td>";
            $temp = $student_id;

        }
echo "</tr></tbody></table>";
    } else {
        echo "0 attendance taken";
