Part 6-Admin Panel(Registration): Delete Data from Database in php
As per the video, we have already downloaded the files and linked the CSS and JS.
Step 1: as you have created a register.php page and inside the table we have delete option, table structure given below:
<?php
include('security.php');
?>
<div class="table-responsive">
<?php
$query = "SELECT * FROM register";
$query_run = mysqli_query($connection, $query);
?>
<table class="table table-bordered" id="dataTable" width="100%" cellspacing="0">
<thead>
<tr>
<th> ID </th>
<th> Username </th>
<th>Email </th>
<th>Password</th>
<th>UserType</th>
<th>EDIT</th>
<th>DELETE</th>
</tr>
</thead>
<tbody>
<?php
if(mysqli_num_rows($query_run) > 0)
{
while($row = mysqli_fetch_assoc($query_run))
{
?>
<tr>
<td><?php echo $row['id']; ?></td>
<td><?php echo $row['username']; ?></td>
<td><?php echo $row['email']; ?></td>
<td><?php echo $row['password']; ?></td>
<td><?php echo $row['usertype']; ?></td>
<td>
<form action="register_edit.php" method="post">
<input type="hidden" name="edit_id" value="<?php echo $row['id']; ?>">
<button type="submit" name="edit_btn" class="btn btn-success"> EDIT</button>
</form>
</td>
<td>
<form action="code.php" method="post">
<input type="hidden" name="delete_id" value="<?php echo $row['id']; ?>">
<button type="submit" name="delete_btn" class="btn btn-danger"> DELETE</button>
</form>
</td>
</tr>
<?php
}
}
else {
echo "No Record Found";
}
?>
</tbody>
</table>
</div>
Step 2: Create a page with the name code.php and paste the below code.
<?php
include('security.php');
if(isset($_POST['delete_btn']))
{
$id = $_POST['delete_id'];
$query = "DELETE FROM register WHERE id='$id' ";
$query_run = mysqli_query($connection, $query);
if($query_run)
{
$_SESSION['status'] = "Your Data is Deleted";
$_SESSION['status_code'] = "success";
header('Location: register.php');
}
else
{
$_SESSION['status'] = "Your Data is NOT DELETED";
$_SESSION['status_code'] = "error";
header('Location: register.php');
}
}
?>
Step 3: Create a folder called database and then create a file named dbconfig.php and paste the below code.
<?php
$server_name = "localhost";
$db_username = "root";
$db_password = "";
$db_name = "adminpanel";
$connection = mysqli_connect($server_name,$db_username,$db_password,$db_name);
if(!$connection)
{
die("Connection failed: " . mysqli_connect_error());
echo '
<div class="container">
<div class="row">
<div class="col-md-8 mr-auto ml-auto text-center py-5 mt-5">
<div class="card">
<div class="card-body">
<h1 class="card-title bg-danger text-white"> Database Connection Failed </h1>
<h2 class="card-title"> Database Failure</h2>
<p class="card-text"> Please Check Your Database Connection.</p>
<a href="#" class="btn btn-primary">:( </a>
</div>
</div>
</div>
</div>
</div>
';
}
?>
Step 4: Create a page security.php and paste the below code.
<?php
session_start();
include('database/dbconfig.php');
if($connection)
{
// echo "Database Connected";
}
else
{
header("Location: database/dbconfig.php");
}
?>
