CGI, how to exit ?

[David_246]

Hi,

I would like to check my incomming values to be a real e-mail adres. Unfortunetly when they do not pass I'dd like to exit. This comes with an error. Premature end of Header.
When I leave the exit, the scipt continues and prints the start html-page again.

if ((grep !/\./, $mailadres) || (grep !/@/, $mailadres)) {
print "

Error: E-mail adres has to contain an @ and a .

";
exit;

How do I exit without the premature end of script message?

In a cgi script you can do email addresses in single quotes.

email='someone@your.net';

That avoides the problem of the special character @ which requires a / before it to not casue the premature header error.

David,

I think you are missing a curly bracket, before the exit command.

Otherwise, there is no problem with the code or the exit instance.

print "

"; }
exit;
<<

Should work!

You could try to add two newlines to the start of your print... The problem is you need some newlines between your HTML header and the HTML code. If those are missing, you get an error message like the one you got.

If the curly bracket is your problem, I would place it behind the exit instead of before ;-)

Oops!

Thanks elmar for pointing that out.
