Hi, I am a Perl CGI beginner. I am trying to construct perl statements to do depending on user input, and interpret them at runtime using eval. I execute these commands by writing
eval $commandString; where $commandString is constructed as per user input. if $commandString="simpleSubroutine();" my eval works well, but if $commandString="notSoSimpleSubroutine(\"$string1\", \"$string2\");" my eval bombs with the following message: Insecure dependency in eval while running with -T switch at /var/www/ CGI/process.cgi line 92. Line 92 points to the line eval $commandString; Any pointers on what is going on? I have read about unsafe characters, and tried the following: $safeCommand=uri_escape($commandString); eval $commandString; (that does not work). I have also tried substituting $string1 and $string2 with literals. I.e., I tried $commandString="notSoSimpleSubroutine(\"delta\", \"gamma\");" and that works just fine. So I gathered that the eval could be bombing because, perhaps variables ($string1 and $string2) above are not safe? However, I need the flexibility of using $string1 and $string2. Any workaround? Any help is greatly appreciated. Thanks. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
