Hi,
Your first code snippet contains my $node;
if ($node eq...
Is this a typo? $node will always eq undef in this case. Did you mean my $node = param('node')
You could do it something like this: (untested code): #!/usr/bin/perl
use CGI;
my $node = param('node');
my %lookup_table = (how => 'how_sub', foo => 'foo_sub');
if ($lookup_table{$node} ne '') {
&{$lookup_table{$node}};
} else {
print "Unknown sub called\n";
}
sub how_sub {}
sub foo_sub {}
The %lookup_table and if routine makes sure users cant choose any old sub to run, just the ones you define in the lookup_table.

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).
