While loop form in PHP - php

Question

I want to develop while loop form in PHP. I am able to create different name in each row but don't know how to handle POST value in next page.
Below is my code:
<form action="sms.php" method="post" enctype="multipart/form-data">
<table class="table table-hover" style="border: groove;">
<thead>
<tr>
<th>Student Id</th>
<th>Student Name</th>
<th>Phone Number</th>
<th>Today's Attendance</th>
</tr>
</thead>
<tbody>
<?php
$c = 1;?>
<?php
$database = new Database();
$db = $database->getConnection();
$user = new User($db);
$stmt = $user->present();
while($ro1 = $stmt->fetch(PDO::FETCH_ASSOC))
{
?>
<tr>
<td><input name ="uname" id ="uname" style ="border:none;background: none;" value = "<?php echo $ro1['user_id'] ?>" readonly/></td>
<td><?php echo $ro1['first_name'] ?> <?php echo $ro1['last_name'] ?></td>
<td><input name = "list<?php echo $c++ ?>" id ="cont1" type="number" style ="border:none;background: none;" onBlur="checkAvailability1a()" value="<?php echo $ro1['parent_contact'] ?>"/></td>
<td><input id="press1" name="press1" type="button" value="<?php echo $ro1[$_SESSION['dyy']] ?>" onclick="return change(this);" onBlur="checkAvailability()" class="w3-button w3-teal"/></td>
</tr>
<?php } ?>
</tbody>
</table>
<button name="back"><a href = 'attendance.php'>< Back</a></button>
<button type="submit" name="next">Next</a></button>

Answer 1

You don't need to give your input name a counter based on the loop. You can use array notation for your input name, for example:
<?php
$database = new Database();
$db = $database->getConnection();
$user = new User($db);
$stmt = $user->present();
while($ro1 = $stmt->fetch(PDO::FETCH_ASSOC)) {
?>
<tr>
<td><input name ="uname[]" id ="uname" style ="border:none;background: none;" value = "<?php echo $ro1['user_id'] ?>" readonly/></td>
<td><?php echo $ro1['first_name'] ?> <?php echo $ro1['last_name'] ?></td>
<td><input name = "list[]" id ="cont1" type="number" style ="border:none;background: none;" onBlur="checkAvailability1a()" value="<?php echo $ro1['parent_contact'] ?>"/></td>
<td><input id="press1" name="press1[]" type="button" value="<?php echo $ro1[$_SESSION['dyy']] ?>" onclick="return change(this);" onBlur="checkAvailability()" class="w3-button w3-teal"/></td>
</tr>
<?php } ?>
Then in your next page (sms.php) you can get the request parameter with $_POST['list'] (without the [] ). That parameter will be an array in php.
