You should check that no username match the username_db
open PAGE, "$data_reg" or die "Can't open $data_reg: $!";
while (my $line = <PAGE>) {
($username_db,$password_db,$email_address_db,$name_db,$spare) = sp
+lit "\t",$line;
if ($username eq $username_db) {
$check++;
$found_user++;
last; # exit while
}
}
unless ( $found_user ) {
$problem = "Unfortunately we cannot find reference to the username s
+upplied.<br> Please check with the webmaster of this site.";
print "$problem";
exit;
}
close PAGE;

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
