Update DATE field for an existing record

Upon reading a training item, users must click a button to acknowledge the training.  I have the form set up so that it passes a couple variables to a script that will add the DATE() to the record.  I cannot get the $date variable into the database.  Any advice would be greatly appreciated.

Here is my code for the page that inserts that date() into the existing record:
<?php

require_once '../scripts/app_config.php';
require_once '../scripts/database_connection.php';


$user_id = $_GET['user_id'];
$item_id = $_GET['item_id'];
$date = date();

$insert_sql = sprintf("INSERT INTO user_training_items (date_completed) VALUES ('%s') WHERE user_id=$user_id AND item_id=$item_id",
					  mysql_real_escape_string($date));
         
// Insert the user into the database
mysql_query($insert_sql);


// Redirect the user to the page that displays user information
header("Location: ../user_profile.php");
exit();
?>

Open in new window


The table in question (user_training_items) has three fields:
item_id
user_id
date_completed

The item_id and user_id are populated upon user account creation.  The date_completed field is NULL by default.

If you are updating a record then you cannot INSERT

$insert_sql = sprintf("UPDATE user_training_items set date_completed = '%s' WHERE ...

I get this error if I try to run the first part of your script:
Warning: date() expects at least 1 parameter, 0 given

You need to put at least one formatting parameter in there.  This is the recommended format for insert or update in MySQL.
$today = date("Y-m-d H:i:s");                   // 2001-03-10 17:16:18 (the MySQL DATETIME format)

date();
Almost certainly the wrong PHP function, or at least the arguments you need are omitted.  When you are not 100% certain about how a PHP function works, you can look up the PHP functions on the php.net web site.  Example:
