    hi, I've made some changes to previous code: <?php //defining variables $error_quote=NULL; $error_author=NULL; $error_date=NULL; $error_url=NULL; $error_flag = true; $genre=NULL; $quote=NULL; $author=NULL; $date=NULL; $url=NULL; $genre=NULL; $redisplay = TRUE; if (isset($_POST['submit'])) { array_map('trim', $_POST); // trim() the entire $_POST array at once. if ( !isset($_POST['quote']) || strlen($_POST['quote']) < 2 || strlen($_POST['quote']) > 16 ) { // if form field 'quote' value not set, or too short or too long, error $error_quote="Please enter a <b>Quote</b> between 2 to 16 characters long <br/>"; $error_flag = true; } else { // otherwise, assign value of form field 'quote' to the $quote variable. $quote = $_POST['quote']; } if( !isset($_POST['author']) || strlen($_POST['author']) < 2 || strlen($_POST['author']) > 16) { // this is same as above $error_author="Please enter an <b>Author</b> between 2 to 16 characters long <br/>"; $error_flag = true; } else { $author = $_POST['author']; } if( !isset($_POST['q_date']) || strlen($_POST['q_date']) < 2 || strlen($_POST['q_date']) > 24) { // same as above $error_date="Please enter a <b>Date</b> between 2 to 24 characters long <br/>"; $error_flag = true; } else { $q_date = $_POST['q_date']; } if( !isset($_POST['url']) || strlen($_POST['url']) < 2 || strlen($$_POST['url']) > 246) { // same as above $error_url="Please enter a <b>URL</b> between 2 to 246 characters long <br/>"; $error_flag = true; } else { $url = $_POST['url']; } if( !isset($_POST['genre']) || !in_array($_POST['genre'], array( 'humour', 'politics', 'romance')) ) { // if form field 'genre' not set, or isn't one of the only three permitted values, error $error_genre=" - Please select a <b>Genre</b>. <br/>"; $error_flag = true; } else { // else assign value to variable $genre = $_POST['genre']; } if ($error_flag !== true) { // If there are no validation errors, run the DB query. $dbhost = 'localhost'; $dbuser = 'lenstanbera'; $dbpass = '27yriloba'; $dbname = 'anevins'; // make a connection to the database $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die('Connection failed: '. mysql_error()); // select the database mysql_select_db($dbname) OR die('Database select failed: '. mysql_error()); // set up the query to insert the new data $query = "INSERT INTO quotes (id, quote, author, q_date, url, genre) VALUES ('', '$quote', '$author', '$q_date', '$url', '$genre')"; $result = mysql_query($query) OR die('Query failed: ' . mysql_error()); if( mysql_affected_rows() > 0 ) { // check to see if a row was actually inserted. echo "<p>Thank you for adding your quote</p>"; $redisplay = FALSE; // if a record was inserted, set $redisplay = FALSE to prevent form redisplay } else { echo "Sorry, your quote was not added to the database."; } } } if( $redisplay !== FALSE ) { // Only redisplay form if $redisplay has not been set to FALSE ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Form to add quotes</title> </head> <body> </body> <form method="post" action=""> <!-- Using echo $_SERVER['PHP_SELF'] is a known XSS vulnerability.

    hello. I took pikachu2000 code and tested. Got problems with undefined variables. I've changed the code to: <?php //defining variables $error_quote=NULL; $error_author=NULL; $error_date=NULL; $error_url=NULL; $genre=NULL; $quote=NULL; $author=NULL; $date=NULL; $url=NULL; $genre=NULL; $redisplay = TRUE; if (isset($_POST['submit'])) { array_map('trim', $_POST); // trim() the entire $_POST array at once. if ( !isset($_POST['quote']) || strlen($_POST['quote']) < 2 || strlen($_POST['quote']) > 16 ) { // if form field 'quote' value not set, or too short or too long, error $error_quote="Please enter a <b>Quote</b> between 2 to 16 characters long <br/>"; $error_flag = true; } else { // otherwise, assign value of form field 'quote' to the $quote variable. $quote = $_POST['quote']; } if( !isset($_POST['author']) || strlen($_POST['author']) < 2 || strlen($_POST['author']) > 16) { // this is same as above $error_author="Please enter an <b>Author</b> between 2 to 16 characters long <br/>"; $error_flag = true; } else { $author = $_POST['author']; } if( !isset($_POST['q_date']) || strlen($_POST['q_date']) < 2 || strlen($_POST['q_date']) > 24) { // same as above $error_date="Please enter a <b>Date</b> between 2 to 24 characters long <br/>"; $error_flag = true; } else { $q_date = $_POST['q_date']; } if( !isset($_POST['url']) || strlen($_POST['url']) < 2 || strlen($$_POST['url']) > 246) { // same as above $error_url="Please enter a <b>URL</b> between 2 to 246 characters long <br/>"; $error_flag = true; } else { $url = $_POST['url']; } if( !isset($_POST['genre']) || !in_array($_POST['genre'], array( 'humour', 'politics', 'romance')) ) { // if form field 'genre' not set, or isn't one of the only three permitted values, error $error_genre=" - Please select a <b>Genre</b>. <br/>"; $error_flag = true; } else { // else assign value to variable $genre = $_POST['genre']; } if ($error_flag !== true) { // If there are no validation errors, run the DB query. $dbhost = 'localhost'; $dbuser = 'lenstanbera'; $dbpass = '27yriloba'; $dbname = 'anevins'; // make a connection to the database $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die('Connection failed: '. mysql_error()); // select the database mysql_select_db($dbname) OR die('Database select failed: '. mysql_error()); // set up the query to insert the new data $query = "INSERT INTO quotes (id, quote, author, q_date, url, genre) VALUES ('', '$quote', '$author', '$q_date', '$url', '$genre')"; $result = mysql_query($query) OR die('Query failed: ' . mysql_error()); if( mysql_affected_rows() > 0 ) { // check to see if a row was actually inserted. echo "<p>Thank you for adding your quote</p>"; $redisplay = FALSE; // if a record was inserted, set $redisplay = FALSE to prevent form redisplay } else { echo "Sorry, your quote was not added to the database."; } } } if( $redisplay !== FALSE ) { // Only redisplay form if $redisplay has not been set to FALSE ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Form to add quotes</title> </head> <body> <form method="post" action=""> <!-- Using echo $_SERVER['PHP_SELF'] is a known XSS vulnerability.

    I've pasted your code, created database and table accordingly, and when I run it, this is what it gave me: see attachment [attachment deleted by admin]

    I'm new to PHP but done some C++, but as much as I see they are very similar. when you assign value to variable, it's stored in memory until it's unset "PHP". you using the same variable $timestamp in stop script as in start, statement: $timestamp = date('Y-m-d H:i:s'); in stop script gives $timestamp date-time value of time stop script is executed, hence reassigning new date-time value. In stop script, replace $timestamp variable with something different eg: $stop_timestamp or anything you fancy, so stop script should look like this: <?php date_default_timezone_set('Europe/Brussels'); $stop_timestamp = date('Y-m-d H:i:s'); $conn = mysql_connect('server', 'user', 'pw') or die(mysql_error()); mysql_select_db('hystudi_timesheets', $conn) or die(mysql_error()); $records = mysql_query("SELECT id, t_start_timestamp FROM timesheet ORDER BY id DESC LIMIT 1"); while ($row = mysql_fetch_array($records)) { $id = $row['id']; $start_timestamp = date("U", strtotime($row['t_start_timestamp'])); } $duration = (date("U", strtotime($stop_timestamp)) - $start_timestamp) / 3600; // duration mysql_query("UPDATE timesheet SET t_end_timestamp = '$stop_timestamp', t_calculated_time = '".round($duration,2)."' WHERE id = $id", $conn) or die(mysql_error()); ?> As I've mentioned I'm new to PHP, so hopefully this solution helps. If not, hopefully somebody else will come up with it.
