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:

}
// Check for MediaID.
if (strlen($_POST['MediaID']) 0) {
$MediaID = TRUE;
} else {
$MediaID = FALSE;
$message .= 'pYou forgot to enter a Media ID!/p';
}
// Set the page title and include the HTML header.
$page_title = 'submit!';

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?
