Eval works ok, but you're using the 'quote' version here, so i'd do a
if ($class !~ /^[a-z0-9_]*$/i) {
print $cgi->header();
print "<h1> You tried something that's not allowed! </h1><br><
+br>";
exit();
}
before using the eval statement.
Alternative you'd be able to use:
eval {
require $class . ".pm";
};
if ($@) {
print $cgi->header();
print "$@";
print "<h1> The class '$class' does not exist! </h1><b
+r><br>";
} else {
# Do your stuff.
$class->main($cgi,$user);
}

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).
