  1. Ben, Hats of too you my friend you're a genius! I amended line 57 to if (is_numeric($_GET['route_id'])) and line 60 to $id = $_GET['route_id']; All is now working. Thank you so much for your assistance Take care, Gunny
  2. Hi Ben, Yes my url ends like this editroute.php?route_id=13 Thanks for your help, I have been going over and over the code for hours now but still cannot find where the issue is! Cheers Gunny
  3. Hi Ben, Great example here, I have been mulling over a way to do this for days! I have obviously had to amend your code somewhat to fit in with my Database setup and required data. The edit.php is successfully pulling the data required. However when I edit the data and click on submit I am getting the Error displayed. I have amended the error messages to identify where the error is, but cannot locate the rror in the code. The error being thrown is for the id being invalid. Can you see where I have gone wrong in the below code at all? Many Thanks Gunny <?php /* EDIT.PHP Allows user to edit specific entry in database */ // creates the edit record form // since this form is used multiple times in this file, I have made it a function that is easily reusable function renderForm($id, $routenumber, $depicao, $arricao, $aircrafttype, $error) { ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>Edit Record</title> </head> <body> <?php // if there are any errors, display them if ($error != '') { echo '<div style="padding:4px; border:1px solid red; color:red;">'.$error.'</div>'; } ?> <form action="" method="post"> <input type="hidden" name="id" value="<?php echo $id; ?>"/> <div> <p><strong>ID:</strong> <?php echo $id; ?></p> <strong>Route Number *</strong> <input type="text" name="route_number" value="<?php echo $routenumber; ?>"/><br/> <strong>Dep ICAO</strong> <input type="text" size="5" name="dep_icao" value="<?php echo $depicao; ?>"/><br/> <strong>Arr ICAO</strong> <input type="text" size="5" name="arr_icao" value="<?php echo $arricao; ?>"/><br/> <strong>Aircraft Type*</strong> <input type="text" name="aircraft_type" value="<?php echo $aircrafttype; ?>"/><br/> <p>* Required</p> <input type="submit" name="submit" value="Submit"> </div> </form> </body> </html> <?php } // connect to the database require_once 'connect.php'; $db_server = mysql_connect($db_hostname, $db_username, $db_password); if (!$db_server) die ("Unable to connect to MySQL: " . mysql_error()); mysql_select_db($db_database) or die("Unable to Select database: " . mysql_error()); // check if the form has been submitted.
