php - 在 PHP 生成的表中显示 MySQL 用户数据

我想用 PHP 和 MySQL 做一个缺勤系统。每个缺勤都有一个休假类型。我想在生成的 HTML 表格中显示这种类型(例如生病)。左侧第一个字段显示用户名,其他为 31 个字段(如月份)。

我可以在表格中输入类型,但是我不知道如何只在正确的表格中显示它们。例如,“Max”的 PK 0 和缺席类型为“Emergency”和“ASDF”,PK 2 和“Compensation”,但类型在两个表中。

Array ( 
[0] =>
Array ( [start] => 0 [end] => 27 [type_FK] => Compensation [employee_FK] => 0 )
[1] =>
Array ( [start] => 1 [end] => 3 [type_FK] => Emergency [employee_FK] => 2 )
)

如何在该表中只显示正确用户的休假类型?

最佳答案

按照这些思路尝试一些事情:

获取一个月的缺勤列表:Select * from abnissions_table

获取员工列表:从 abnances_table 中选择 *

创建一个空的 $employees 数组。循环遍历缺席结果,并针对每次缺席运行如下内容:

  for($i=0;$i<count($absences_array);$i++){
if(!$employees[$absences_array[$i]['employee_FK']]['dates']){
$employees[$absences_array[$i]['employee_FK']]['dates'] = array();
}

$employees[$absences_array[$i]['employee_FK']]['dates'][$absences_array[$i]['employee_FK']['start']];
for( $j=$absences_array[$j]['employee_FK']['start'];$j<$absences_array[$j]['employee_FK']['end']; $j++){
$employees[$absences_array[$i]['employee_FK']]['dates'][$j];
}
}

现在你有一个字典的字典 - 这意味着像 $employees[$employee_id]['dates'][$date] 这样的东西会给你缺席类型或 null。
