Re: Perl beginner  I need help please
[In reply to]

Can't Post


Hi Jenny, it seems it was a bit late when I was answering yesterday. Well I'll try to be more precise this time. Concerning the anonymous thing your assumption is right.
What does the segment in blue mean? $Name is used in some places? As I said, it was late and I didn't find the right words. I meant that the variable $Name is used to insert the name of the form user in the text for both the mail to you and the autoreply mail. If the user doesn't enter a name, nothing is inserted in both mails. It's a matter of taste what solution you choose. So don't hesitate to comment the line out.
Goodluck with that presentation! Thanks a lot. Reminds me that I gotta get myself working now...
What does that mean? You know Regular Expressions? Short term for them is regex. A regular expression is used for an abstract description of some part of a text, e.g. an email address. Regular expressions, even short ones, look quite weird to the beginner. And the email checking regex looks even weird to the perl guru (although he may at least be able to recognize it's a regex ). To give you a little impression, here's the fast version of the email validation regex (please, don't try to understand and don't ask me to explain):

If I use your code is it possible for the poll to have the users select a radio button and then press a submit button to send their vote? I guess that should be no problem. If you can wait for another 48 hours, I can check this out. You can also have a try yourself, the code shoud be readable as long as you have some Perl experience.
Were you unable to vote on the nfl poll because you don’t know anything about football or was the poll broken? No, having nothing to do with football couldn't have stopped me from voting. I just didn't find a submit button or at least any button to click on. Perhaps they closed the poll... Bye, Marcus
