in reply to Error using HTML::Template

I see two errors - one is an error in your code (copy/paste from improperly formatted POD on your end), the other is an actual typo in the POD.

Looking at the POD on CPAN, the line reads:

# send the obligatory Content-Type and print the template output print "Content-Type: text/html\n\n", $template->output;

So it's "print", not "output print". But there is a typo in the POD - that comma before $template->output; should be a period (string concatenation).

print "Content-Type: text/html\n\n". $template->output;

Or, if you're familiar with C, you could also write it in a more recognizable form:

print sprintf("Content-Type:text/html\n\n%s",$template->output);

No difference, really, but sometimes people find it easier to read the latter.


Update: Ok, so I'm wrong about the second bug - I'll plead ignorance to printing in LIST form. That being said, based on the original post, I think a code copy &paste went badly, and that's why you're getting the strange error messages.

PS - and yes, you could just use printf, but you'll get far more use out of sprintf in the long run. :)

    Why?

    #!/usr/bin/perl -l print 1,2,3; $,=$"; print "this","works"; __END__ 123 this works

    This is the print LIST form that is mentioned in perldoc -f print.

    I wouldn't bother with print sprintf(...).. just use printf.

    swngnmonk,

    The comment and line of code are correct in my script. It could be that it showed up incorrectly on the node because I didn't use code tages. Thanks to Allolex pointing that out. It looks fine on my screen because I am using small fonts in my CSS.

    I thought that the comma could be problem too, so I tried using the concatenation operator and also tried using two print statements but to no avail.

    I'm a newbie to programming and web pages so I think using C is out for me right now. Too steep a learning curve.

    Thank you for taking your valuable time to respond.

    Much appreciated,

    Anne
