Update row data with id not carrying id forward - php

Question

Have being trying this query for 3 days now. I have a list of rows here: http://prntscr.com/dick00. All what I want to is to edit and delete each row respectively. For some reason the id is not carrying forward and no record is updating.
When I click on edit in access.php I get edit_access.php?id= in address bar.
Here is my link in access.php
<td><a href="edit_access.php?id=<?php echo $row['id']; ?>"><i class="fa fa-edit"></i>edit</td>
edit_access.php
EDIT 1: php code
<?php
// start session
session_start();
// error_reporting(E_ALL); ini_set('display_errors', 1);
if(!isset($_SESSION['user_type'])){
header('Location: index.php');
}
// include connection
require_once('include/connection.php');
// set user session variables
$userId = $_SESSION['user_id'];
$error = [] ;
if(isset($_POST['update']))
{
$id = $_POST['id'];
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$therapist = $_POST['therapist'];
$access_type = $_POST['access_type'];
$code = $_POST['code'];
$created_at = $_POST['created_at'];
$postcode = $_POST['postcode'];
// validate form field
if (empty($firstname)){
$error[] = 'Field empty, please enter patient first name';
}
if (empty($lastname)){
$error[] = 'Field empty, please enter patient last name';
}
if (empty($therapist)){
$error[] = 'Field empty, please enter your name';
// $error = true;
}
if (empty($code)){
$error[] = 'Field empty, please enter patient access code';
// $error = true;
}

$error[] = 'Field empty, please check access type';
// $error = true;
}
if (empty($postcode)){
$error[] = 'Field empty, please enter patient postcode';
// $error = true;
}
//if no errors have been created carry on
if(empty($error)){
$updated_at = date('Y-m-d');
// ************* UPDATE PROFILE INFORMATION ************************//
if(!($stmt = $con->prepare("UPDATE access SET firstname = ?, lastname = ?, therapist = ?, access_type = ?, postcode = ?, code = ?, updated_at = ?

}

exit;
}else{

<?php

Answer 1

you most put your id inside of a hidden input in your html form like this:
<input type="hidden" name="itemId" value="<?php echo '$_GET['id']'?>">
and then when you submit your form you have itemId in side $_POST['itemId'] variable.
EDIT:
I must describe scenario for you. maybe you got the point.
you have a list of access witch in every row has this tag:
access ....
in your access-form.php you have a form with this structure:
<form method="post" action="edit-access.php">
.....
<input type="hidden" name="id" value="<?php echo $_GET['id']?>">
.....
</form>
next in your edit-access.php you can access to this id by this syntax:
echo $_POST['id'];
