PHP 中的考勤门户

我在生成最终出勤报告时遇到问题

我被困在项目的最后阶段：

我有一个出勤表，如果学生在场，我将其标记为 1，如果缺席 0。我们有日期，星期顺序，小时（我们遵循日顺序时间表）

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

餐桌出勤率：

我必须像下面这样生成一个月度报告

我尝试过的代码：

SELECT student_id,deptno,Month, Year_c,
branch.description as bdesc,
course.coursecode as ccd, 
users.firstname as ufn, 
users.lastname as uln,
course.description as ccdes,schedules.hour as hhour,
h,dayorder,AttdDate,
CONCAT(AttdDate,h,dayorder) AS fate,

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

【问题讨论】：

你需要规范你的数据库。
@Dharman 你能帮忙举几个例子吗
未定义：student_rollno。请修复。
phpmyadmin 中的输出与“必须生成”示例不匹配。我们应该为哪一个而努力？
主表请提供SHOW CREATE TABLE。

【解决方案1】：

我为你的情况写了一个 PHP MySQL 的例子，但没有得到你的 SQL，为什么你有一天的描述也是第一个头不知道的。此外，您必须在几个小时内添加代码，这只是 PHP MySQL 示例的正确方法，如果您卡住了，我建议您使用 ez_SQL 更好的对象编程与 oho MySQL，不要犹豫评论

    <?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";
    }

【讨论】：

我们有日订单系统，例如从第 1 天到第 6 天和星期六，有 7 个时段，每个日期都分配有一个天订单。在给定的图片中，您可以查看描述“2019-06-17”是日期“5”是期间“Day6”是日订单
因此，只需在 foreach 中添加 Dayorder 并检查订单中当前日期的位置，这样您就可以安排 tahat 但尝试代码看看发生了什么，它会让您对它有所了解
