Hello everyone,
I have this form that we use for keeping track of tapes we send off site for storage where I work. The form works almost perfectly with the help of a few people.
We use a scanner to input the tape id's. The scanner automatically puts a carriage return at the end of each tape so they all go on seperate lines.
Anyway the question is this: After the last tape is scanned I end up with a line put into the mysql db that looks like this: (from mysql log file)
243 Query INSERT INTO tape_tracking_test (media_id,retention,out_date,return_date,box_id) values ('','7WK=%s','2005-01-11','2005-3-01','006455C5092800')
If you look closely you'll see the first field is '' Single quotes with nothing in between.
How can I get PHP to ignore that line that has empty data in the media_id field? I have checking in place to not allow empty fields but PHP/mysql think that last carriage return is not empty.
I don't want to tell users they have to backspace at the end of the last tape (which fixes the problem)
I hope I'm explaining this properly. If not I'm sure you guys will let me know :)
Here is the script:
Above here is javascript for a calendar
//--> </script>
</head>
<Body> <body onLoad="showCalendar('now')">
<?php
if (isset($_POST['submit'])) { // Handle the form.
$message = NULL; // Create an empty new variable.
}
// Check for MediaID. if (strlen($_POST['MediaID']) > 0) { $MediaID = TRUE; } else { $MediaID = FALSE; $message .= '<p>You forgot to enter a Media ID!</p>'; }
// Set the page title and include the HTML header. $page_title = 'submit!';
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> <fieldset><legend>Enter the Tape information into the form below:</legend>

Hi Mike
I am not sure of the format of the media id, but can you not use a simple regex so that if mediaID is not of a certain pattern (e.g. all alphanumeric and a certain length), the relevant corrective action is taken?
