<tr>
        <td bgcolor='yellow'><center></td>
        <td bgcolor='yellow'><center>Name</td>

//retrieving data from temporary table that needs to be validate first by the administrator before it goes to the official table

$retrieve_query = mysqli_query($connections, " SELECT * FROM temptbl WHERE status='pending'");

//retrieving data from temptbl

while($row_users = mysqli_fetch_assoc($retrieve_query)) {

    $db_id = $row_users["temp_id"];
    $ins_name = $row_users["name"];
    $ins_address = $row_users["address"];

    echo "<form method='POST' action='accept.php'>";
    echo "  <tr>

            </tr>";




}
?>
</table>
<hr>

<input type="submit" name="accept" value="Accept">
</form>

AND this is the accept.php file:

<?php
include ("connections.php");
//if accept button submits, it will insert all the checked checkboxes that contains the data from table rows
    if(isset($_POST['accept'])) {
 //inserting values to official table
        $query = mysqli_query($connections, "INSERT INTO mytbl (name,address,email,password,account_type)
                VALUES('$ins_name','$ins_address','$ins_email','$ins_password','2') ");
//and updates all pending to good or done
        mysqli_query($connections, "UPDATE temptbl SET status='good' WHERE status='pending'");

//notifications
        echo "<script language='javascript'>alert('New record has been inserted!')</script>";
        echo "<script>window.location.href='index.php';</script>";  
    }

}
