I have the following script segment:
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++;
} else {
$problem = "Unfortunately we cannot find reference to the
+username supplied.<br>
Please check with the webmaster of this site.";
print "$problem";
exit;
}
}
close PAGE;
This seemes always to fail ar the first pass and does not check the rest of the lines.
I can get round this by taking the 'else' statement out and doing (after close PAGE):
if ($check){
#do something;
} else {
$problem etc.
}
But I don't want to!
can someone tell me why the original fails to lookup the whole file?

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).
