Issue
Good day, I've seen a couple of threads with similar questions but I can't seem to implement the suggestions on my practice project.
is there any way I can add a function where my selected items can be deleted at once?
Here are my codes.
select.php
<?php
$connect = mysqli_connect("localhost", "root", "root", "appointments");
$output = '';
$sql = "SELECT * FROM appointments ORDER BY id DESC";
$result = mysqli_query($connect, $sql);
$output .= '
<div class="table-responsive">
<table class="table table-bordered">
<tr>
<th width="5%">Checkbox</th>
<th width="10%">Id</th>
<th width="40%">Name</th>
<th width="40%">Email</th>
<th width="40%">Address</th>
<th width="10%">phoneNumber</th>
<th width="10%">appointmentTime</th>
<th width="10%">appointmentDate</th>
<th width="50%">message</th>
<th width="10%">delete</th>
</tr>';
if(mysqli_num_rows($result) > 0)
{
while($row = mysqli_fetch_array($result))
{
$output .= '
<tr>
</td>
<td><input type="checkbox" /></td>
<td>'.$row["id"].'</td>
<td class="name" data-id1="'.$row["id"].'" contenteditable>'.$row["name"].'</td>
<td class="email" data-id2="'.$row["id"].'" contenteditable>'.$row["email"].'</td>
<td class="address" data-id2="'.$row["id"].'" contenteditable>'.$row["address"].'</td>
<td class="phoneNumber" data-id2="'.$row["id"].'" contenteditable>'.$row["phoneNumber"].'</td>
<td class="appointmentTime" data-id2="'.$row["id"].'" contenteditable>'.$row["appointmentTime"].'</td>
<td class="appointmentDate" data-id2="'.$row["id"].'" contenteditable>'.$row["appointmentDate"].'</td>
<td class="message" data-id2="'.$row["id"].'" contenteditable>'.$row["message"].'</td>
<td><button type="button" name="delete_btn" data-id3="'.$row["id"].'" class="btn btn-danger btn_delete">Delete</button></td>
</tr>
';
}
}
else
{
$output .= '<tr>
<td colspan="10"><center><p style="color:red">No Data Found</p></center></td>
</tr>';
}
$output .= '</table>
</div>';
echo $output;
?>
Here's the delete function for a single row.
<?php
$connect = mysqli_connect("localhost", "root", "root", "appointments");
$sql = "DELETE FROM appointments WHERE id = '".$_POST["id"]."'";
if(mysqli_query($connect, $sql))
{
echo 'Data Deleted';
}
?>
Here's my display page.
<?php
require("config.php");
if(empty($_SESSION['user']))
{
header("Location: success.php");
die("Redirecting to index.php");
}
?>

Solution
I'm not sure exactly how you are sending the data from the HTML to the PHP page in this example, so I will give you a generic simple implementation and hopefully you can figure out how to work it into your project.
HTML:
Using checkboxes, you can send multiple values as an array to a php script like so.
<form action="delete.php" method="POST">
<input name="delete[]" value="id_of_row" type="checkbox">
<input name="delete[]" value="id_of_another_row" type="checkbox">
<button type="submit">Submit</button>
</form>
This will send an array of whatever is in the value attribute of each box that is checked. You would then be able to delete every row that was checked with the following php script.
PHP:
<?php
$connect = mysqli_connect("localhost", "root", "root", "appointments");
foreach($_POST['delete'] as $id){
$sql = "DELETE FROM appointments WHERE id = '" . $id . "';
if(mysqli_query($connect, $sql))
{
echo 'Data Deleted';
}
}
?>
This should be what you need to somehow implement into your existing project so that you can delete multiple rows at once.
