Only one radio button value is inserted in php - php

Question

I have a dynamic radio button that inserts a list of student attendance data
but only one student data is inserted. What am I doing wrong
When only the first student gets inserted. The rest of the students do not get inserted into the database
<div class="table">
<table class="table table-sm table-bordered mx-auto">
<tr>
<th>Student Name</th>
<th>Attendence Status</th>
</tr>
<tbody>
<?php
while ($row=mysqli_fetch_array($select)) {
$student_id=$row['student_id'];
$student_name=$row['student_lastname'].' '.$row['student_midname'].' '.$row['student_firstname'];
$link='student_images/'.$row['student_img'];
?>
<tr>
<td class="px-md-2" ><?php echo '<img src="'.$link.'" class="profile-user-img img-fluid img-circle" alt="Student Picture" />' ?>
<p class="profile-username lead"><?php echo $student_name; ?></p>
<p class="text-muted "><?php echo "Date:".' '.date("d/m/Y"); ?></p>
</td>
<td class="mx-auto" style="width: 40%;">
<div class="radio icheck-square">
<input type="radio" value="1" id="state" name="<?php echo $student_id; ?>" />
<label for="present">Present</label>
</div>
<div class="radio icheck-square">
<input type="radio" value="0" id="state" name="<?php echo $student_id; ?>" />
<label for="absent">Absent</label>
</div></td>
</tr>
<input type="hidden" name="student_id" id="student_id" value="<?php echo $student_id ?>">
<input type="hidden" name="date" id="date" value="<?php echo date("Y/m/d"); ?>">
<?php
}
?>
</tbody>
</table>
<div class="row">
<div class="col">
<button class="btn btn-primary" onclick="AddOnly();">Add Attendance Only</button>
or
<button class="btn btn-info" onclick="AddSend();">Add Attendance & Alert Parents</button>
</div>
</div>
</div>
</div>
The PHP code is that processes the data is below
$state=$_POST['state'],
$student_id=$_POST['student_id'];
$date=$_POST['date'];
$insert=mysqli_query($conn,"INSERT INTO `aza_attendance`(`attendance_id`, `student_id`, `atten_date`, `state`) VALUES (NULL, '$student_id', '$date', '$state')") or die(mysqli_error($conn));
if ($insert) {
if ($state==1) {
echo $student_id. 'was at school on'.' '.$date;
}else if($state==0){
echo $student_id. 'was at <strong>NOT</strong> school on'.' '.$date;
}
}

i think is not good to use a variable in name like you use here name="" i think this is better just put them in one div
<div class="radio icheck-square">
<input type="radio" value="1" id="state" name="state" />
<label for="present">Present</label>
<input type="radio" value="0" id="state" name="state" />
<label for="absent">Absent</label>
</div>
