The first line of the code is this:
open (LOGFILE, ">>guestbook.log");
The next line is the join statement. This is an extremely
useful tool for adding data to delimited text files. The statement
$newline=join('::',@value);
means take each value in the @value array (each entry box on the HTML
form), and join them with double colons.
$newline could now contain this:
Robert::Young::5 Main St.::Anytown::MA::02177::(617) 555-1212::robyoung@mediaone.net::on::This
is Great
Now that $newline is complete, I am ready to add it to the end of guestbook.log.
Since I already have a file handle for the log file, appending to it is
as easy as this:
print LOGFILE ("$newline\n");
It will add the entire contents of $newline to the end of guestbook.log.
I also asked it to add a \n (carriage return) to the end of $newline, so
that the next time I append something, it will start at the beginning of
a new line.
close LOGFILE;
It stands to reason that if I have to open a connection to the file
when I begin my program, I should close that connection when I am through.
Lastly, I printed something to the screen. This is more than just a courtesy. You have to write something or else you get a 'document contains no data' error. So we wrote this:
print "<BODY BGCOLOR=\'BEIGE\'><H1>Thank you. Your comments
have been added</H1>";
How do I get the data? |
