I am using php and mysql to update user data inside of the database as admin, i have a text box which allows the admin to input approved or not approved, now i want to try change the text box for the approved or not approved into a check box where the admin can just click on the check box approved and the data will be updated according to the user which was selected as im not really sure how to go about it. thanks

require('connection.php');
if (isset($_POST['submit'])) {
$prescription = $_FILES['prescription']['name'];
$image_tmp = $_FILES['prescription']['tmp_name'];
move_uploaded_file($image_tmp,"medical-prescription/$prescription");
$sql = $conn->prepare("UPDATE users SET approved=?,prescription=? WHERE id=?");
$approved=$_POST['approved'];
$sql->bind_param("ssi",$approved, $prescription,$_GET["id"]);

You can do it this way:
Change HTML:
<input type="checkbox" name="approved" class="txtField" value="<?php echo $row["approved"]?>"> Approved?
php:
Replace this:
...
$approved=$_POST['approved'];
...
with:
...
$approved=(isset($_POST['approved'])) ? $_POST['approved']: "Not approved"; // Or any other text value what you use
...
Here is formatted code:
<?php
require('connection.php');
if (isset($_POST['submit'])) {
$prescription = $_FILES['prescription']['name'];
$image_tmp = $_FILES['prescription']['tmp_name'];
move_uploaded_file($image_tmp,"medical-prescription/$prescription");
$sql = $conn->prepare("UPDATE users SET approved=?,prescription=? WHERE id=?");
//HERE WE CHANGE
$approved=(isset($_POST['approved'])) ? $_POST['approved']: "Not approved";
$sql->bind_param("ssi",$approved, $prescription,$_GET["id"]);
if($sql->execute()) {
$success_message = "Edited Successfully";
} else {
$error_message = "Problem in Editing Record";
}
}
$sql = $conn->prepare("SELECT * FROM users WHERE id=?");
$sql->bind_param("i",$_GET["id"]);
$sql->execute();
$result = $sql->get_result();
if ($result->num_rows > 0) {
$row = $result->fetch_assoc();
}
$conn->close();
?>
<?php if(!empty($success_message)) { ?>
<div class="success message"><?php echo $success_message; ?></div>
<?php } if(!empty($error_message)) { ?>
<div class="error message"><?php echo $error_message; ?></div>
<?php } ?>
<form method="post" action="" enctype="multipart/form-data">
<label>approved</label>
<input type="checkbox" name="approved" class="txtField" value="<?php echo $row["approved"]?>"> Approve?
<label>Medical prescription</label>
<input type="file" name="prescription" id="prescription" required/><br>
<input type="submit" name="submit" value="Submit" class="demo-form-submit">
</form>
Here is the test:
$('form').on('submit', function(e){
e.preventDefault();
var data = $(this).serialize();
alert("Submitted data: {" + data + '}');
});

<form>
<input type="checkbox" name="approved" class="txtField" value="Yes"> Approved?
<button type="submit" name="submit" value="submit">Submit</button>
</form>
