带有单选按钮的简单考勤系统


simple attendance system with radio button

我正在制作一个简单的考勤类系统

我这里有这个带有单选按钮的 php 代码.. 现在我把它放在一个表格中

我只能在整个表格上选择一个单选按钮,而不是每个注册帐户一个单选按钮

<?php
session_start();
if(!isset($_SESSION["in"]))
{
    header("Location: log.php");
}
?>

    <body>

<?php
echo "Today is " . date("m/d/Y") . "<br><br><br><br>";
?>
<?php
$conn= new mysqli("localhost", "root", "", "dbform");
    $sql = "SELECT * FROM tblusers";

$result = $conn->query($sql);
if ($result->num_rows > 0) {
    echo "<table width='1300' border='6'> 
<tr>
<th width='100'>ID</th>
<th width='100'>Lastname</th>
<th width='100'>Firstname</th>
<th width='100'>Sex</th>
<th width='100'>Attendance</th>
</tr>";
     // output data of each row
     while($row = $result->fetch_assoc()) {
         echo "<tr> ";
echo "<td align='center'>2016" . $row['id'] . "</td>";
echo "<td align='center'>" . $row['lastname'] . "</td>";
echo "<td align='center'>" . $row['firstname'] . "</td>";
echo "<td align='center'>" . $row['sex'] . "</td>";
?>
<form method="post" action="Succes_Submit_Attendace.php" name="submit_attendance">
attendance = 
<td align='center'> <label><input type="radio" name="attendance" value="present">Present</label>
              &emsp;<label><input type="radio" name="attendance" value="absent">Absent</label><br /><br />
<?php  
$row['attendance'] ;
?> </td>
<?php 
echo " </tr>";
     }
     echo "</table>";
} 
else {
     echo "0 results";
}
$conn->close();
?>   
<br>
<br>
<input type="reset">&emsp;<input type="submit" value="Submit Attendance"></h4>
</form>

<div align="right">
 <a href="admin.php"><h3>Back</h2></a>
</div>

所有单选按钮的名称都相同,因此您需要按行 ID 对它们进行分组。 将输入类型更改为以下内容:

<label><input type="radio" name="attendance[<?php echo $row['id']; ?>]"  value="present">Present</label> 
&emsp;
<label><input type="radio" name="attendance[<?php echo $row['id']; ?>]" value="absent">Absent</label><br /> <br />

代码中也存在 HTML 错误。请修复它们
