Friends here is 2nd parts. Here we will go ahead and make files for edit and delete customer record.

We change our list.php as below. We include edit and delete button.

list.php

 < ?php

include ('menue.php');        

if(isset($_GET['updatestatus'])) {

echo  $delstatus =$_GET['updatestatus'];

}

?>

 < center>

 < ?php include "db.php";

 ?>

 < h2>Customer Contact List < /h2>

 < table border="1" cellpadding="8">

 < tr> < th>ID < /th> < th>Name < /th> < th>Phone < /th> < th>Email < /th> < th>Address < /th> < th>Date < /th> < th>Edit < /th> < th>Delete < /th> < /tr>

 < ?php

$result = $conn->query("SELECT * FROM customers ORDER BY id DESC");

while($row = $result->fetch_assoc()){

 ?>

   < tr>

              < td>  < ?php echo $row['id']; ?>  < /td>

             < td>  < ?php echo $row['name']; ?>  < /td>

             < td>  < ?php echo $row['phone']; ?>  < /td>

             < td>  < ?php echo $row['email']; ?>  < /td>

             < td>  < ?php echo $row['address']; ?>  < /td>

             < td>  < ?php echo $row['created_at']; ?>  < /td>

     < td> < a href="edit_list.php?editid= < ?php echo $row['id'];?>"> Edit < /td>      

     < td> < a href="delete.php?delid= < ?php echo $row['id'];?>"> Delete < /td>

     < /td>

< /tr>

   < ?php     

}

?>

 < /table>

 < /center>

< ?php

include ('footer.php');

?>

Here we create edit_list form and save it

edit_list.php

< ?php

include ('menue.php');        

include "db.php";

if(isset($_GET['editid'])){

$edit_record = $_GET['editid'];

$result = $conn->query("SELECT * FROM customers where id = '$edit_record' ");

while($row = $result->fetch_assoc()){

 $cust_id=$row['id'];

$cust_name=$row['name'];

$cust_phone=$row['phone'];

$cust_email=$row['email'];

$cust_address=$row['address'];

$cust_note=$row['notes'];

$cust_date=$row['created_at'];

}}

?>

Here is  codes for delete record

Delete.php

 < ?php

include "db.php";

if(isset($_GET['delid'])){

echo $delete_record = $_GET['delid'];

$sql = "delete from customers where id='$delete_record'";

if($conn->query($sql) === TRUE){

    $updatestatus= "Selected Customer deleted.... ";

  } else {

    $updatestatus= "Error: " . $conn->error;

  }

$conn->close();

header("location: list.php?updatestatus=$updatestatus");

}

?>
