我在admin.php文件中的表单中有多个提交按钮。对于管理员执行的每个操作，我在admin.php文件中有一个提交按钮。管理员（每日出勤）的一项行动是将员工的出勤标记为现在或不在。
当我点击＆＃34;每日出勤＆＃34;的提交按钮时，出现3个下拉选项，允许管理员选择年份，月份和日期来标记出勤率。除此之外，还会显示一个表，其中包含employee表中的所有记录。对于显示的每条记录，我动态生成一个用于出勤的单选按钮（值：存在和不存在）和一个提交按钮（名称=标记）。管理员只需在单选按钮的帮助下将任何一名员工标记为现在/不在，并点击相邻的提交按钮（标记）将该记录插入考勤表。
每条记录的选择（年，月，日）和单选按钮是动态生成表单的一部分。在这种形式中，我将ACTION属性赋予＆＃34; mark-attendance.php＆＃34;和method = POST。
现在，我想传递年，月和日期的选定值;出现或缺席的出勤值，以及记录出勤记录的员工的员工ID，到页面＆＃34; mark-attendance.php＆＃34;通过POST方法。
我能够检索年，月，日（选择）和出勤值（出现/缺席）的值。但我无法将该人员的员工ID值传递给＆＃34; mark-attendance.php＆＃34; ，因为它不是表格输入。
如何传递此值？我想使用此值在该特定员工ID的考勤表中插入记录。
任何帮助将不胜感激：
这是我的代码：我已经编辑了空间约束的代码

首先，在回显html代码时使用'而不是'
echo '<a href="#">'更容易编写。
所以对于你的问题，我会按照以下方式进行：
添加一个额外的隐藏输入，其中包含员工ID作为其值 在php中查看它。有关详细信息，请参阅此主题：Multiple inputs with same name through POST in php
..
<td>' . $row['emp_id'] . '<input type="hidden" name="employee[]" value="' . $row['emp_id'] . '"</td>
..
答案 1 :(得分：0)
由于您在name循环内运行form，因此无需将while属性放入数组中。您只需在form
<input type="hidden" name="emp_id" value="<?php echo $row['emp_id']; ?>" />
这样您就可以通过$_POST['emp_id'];
答案 2 :(得分：0)
我为每个显示的员工记录动态生成了一个表单。生成的每个表单都包含以下
这样，我就可以将值传递给attendance.php文件，该文件标志着每位员工的出勤率。
下面这段代码非常适用。我编辑了我的代码以提高可读性以及解决空间约束问题。
